The LVDS receiver 3315 receives LVDS signals including video signals and VSYNC signals from the sub control board 3200 via the relay board 3301, and outputs these data to the control LSI 3311 and the DLP control circuit.

The DLP system of the projector apparatus 3300 is mainly composed of a DLP control circuit 3313, an LED driver 3314, LED light sources 3331 (3331R, 3331G, 3331B) of the optical mechanism 3330, and a DMD3333.

The DMD3333 has mirrors corresponding to pixels corresponding to the display resolution integrated on the main surface of a semiconductor chip. The DMD 3333 is constructed such that each mirror is tilted +10° or −10° around the axis along the diagonal line with respect to the main surface by the electrostatic field action of the memory element directly below each mirror. With such a configuration, each mirror of the DMD 3333 can be switched between an ON state (a state of reflecting light in a predetermined direction) and an OFF state (a state of reflecting light outside the predetermined direction). That is, each mirror of the DMD 3333, when in the ON state, guides the light incident from the LED light sources 3331R, 3331G, and 3331B via dichroic mirrors (not shown) and the like to the lens unit 3332 again via the dichroic mirrors and the like, while it is in the OFF state. In this state, light incident from the LED light sources 3331R, 3331G, and 3331B through a dichroic mirror or the like is reflected in a direction other than the lens unit 3332. FIG.

The DLP control circuit 3313 controls an LED driver 3314 that drives the LED light sources 3331R, 3331G, and 3331B, and transmits RGB light from the LED light sources 3331R, 3331G, and 3331B in a time-division manner to the DMD 3333 via a dichroic mirror (not shown). be incident on the At this time, the DLP control circuit 3313 switches the mirror corresponding to which pixel to the ON state or the OFF state at which timing according to the image to be projected. determines whether the light is reflected in a predetermined direction, and controls the ON/OFF state of each mirror of the DMD 3333 .

In addition, as described above, the DLP control circuit 3313 transmits the VSYNC signal to the sub-control LSI 3316 to control the rotation of the glass 3352 of the switching device 3350, and the optical path of the light reflected by the DMD 3333 is switched at a predetermined timing. and enters the lens unit 3332 .

It should be noted that when the light incident through a dichroic mirror or the like is reflected in a direction other than the lens unit 3332 , even if the reflected light is reflected again within the projector device 3300 afterward, the direction of the lens unit 3332 is reflected. The incident light may be controlled to be reflected in a direction other than the lens unit 3332 through a dichroic mirror or the like so that the light does not travel toward the lens unit 3332 .

Under the control of the DLP control circuit 3313, the light reflected by the DMD 3333 in a predetermined direction proceeds to the lens unit 3332, passes through the projection lens, enters the mirror mechanism 3105, and is finally reflected by the mirror mechanism 3105. By doing so, it leads to the projection target. As a result, the illumination light is projected onto the screen and the character object to be projected, and an image corresponding to the presentation is formed.

As shown in FIG. 10, projector device 3300 further includes temperature sensor 3341 , intake fan 3342 , pulse sensor 3343 , exhaust fan 3344 , pulse sensor 3345 and LSI temperature sensor 3346 .

The temperature sensor 3341 consists of a thermistor, for example. A temperature sensor 3341 collectively represents a plurality of temperature sensors. For example, the temperature sensor 3341 detects the temperature near the LED light source 3331R and outputs a temperature detection signal to the projector control board 3310. The temperature sensor 3341a detects the temperature near the LED light source 3331G, and a temperature sensor 3341c that detects the temperature near the LED light source 3331B and outputs the temperature detection signal to the projector control board 3310. FIG. For example, each such temperature sensor 3341a, 3341b, 3341c is located on or near the corresponding LED substrate 3331Ra, 3331Ga, 3331Ba, respectively.

Further, the temperature sensor 3341 further detects the temperature near the DMD 3333 and outputs a temperature detection signal to the projector control board 3310 . It includes a temperature sensor 3341e that outputs a temperature detection signal.

The temperature sensors 3341a, 3341b, 3341c, and 3341d described above are examples of temperature detection means provided near optical elements such as the LED light sources (3331R, 3331G, and 3331B) and DMD 3333, or near the optical elements. Such temperature detection means includes the optical element itself and may include the object on which the optical element is provided. For example, when the temperature detection means is provided on the optical element itself, when the temperature detection means is provided on the substrate on which the optical element is provided, when the temperature detection means is provided near the position where the optical element is arranged, the optical element When the temperature detection means is provided near the substrate provided with the optical element, when the temperature detection means is provided inside the object (for example, projector) provided with the optical element, the temperature changes according to the amount of heat generated by the optical element. This includes the case where a temperature detection means is provided at a position where the temperature of various structures such as air, substrates, electronic circuits, etc. can be detected.

In this embodiment, the temperature sensors (3341a, 3341b, 3341c) that detect the temperature of the LED light sources (3331R, 3331G, 3331B) and the temperature sensor that detects the temperature of the lens unit 3332 detect the temperature in units of 1°C. . That is, the unit in which the temperature detected by these temperature sensors changes (temperature change unit) is 1°C.

On the other hand, the temperature sensor for detecting the temperature of the DMD3333 detects the temperature in units of 0.25.degree. That is, the unit (temperature change unit) in which the temperature detected by this temperature sensor changes is 0.25.degree.

Due to such a configuration, the temperature change related to the DMD 3333 can be detected with higher precision than the temperature change related to the LED light sources (3331R, 3331G, 3331B) and the lens unit 3332 . Note that the temperature change regarding the DMD 3333 includes the temperature change around the DMD 3333, the temperature change of the DMD 3333, the temperature change of the adjacent intake fan 3342, or the temperature change around the exhaust fan 3344. It may include temperature changes of the projector device 3300 . Also, in order to grasp such a temperature change, it is possible to adjust the arrangement position of the temperature sensor 3341d or use another temperature sensor.

The intake fan 3342 includes two intake fans, an intake fan 3342a (FAN4) and an intake fan 3342b (FAN5). The exhaust fan 3344 also includes two exhaust fans, an exhaust fan 3344a (FAN6) and an exhaust fan 3344b (FAN7).

The pulse sensor 3343 is provided so as to output a pulse signal corresponding to the rotational speed of the two pulse sensors, that is, the intake fan 3342a (FAN4), to the projector control board 3310 as a FAN4 rotational speed detection signal. A pulse sensor 3343a and a pulse sensor 3343b provided to output a pulse signal corresponding to the rotation speed of an intake fan 3342b (FAN5) to the projector control board 3310 as a rotation speed detection signal for FAN5. include. The pulse sensor may be composed of, for example, a photointerrupter.

The pulse sensor 3345 is provided so as to output a pulse signal corresponding to the number of revolutions of the exhaust fan 3344a (FAN6) to the projector control board 3310 as a detection signal of the number of revolutions of the fan 6. A pulse sensor 3345a and a pulse sensor provided to output a pulse signal corresponding to the rotation speed of an exhaust fan 3344b (FAN7) to the projector control board 3310 as a detection signal for the rotation speed of FAN7. 3345b. This pulse sensor may also be composed of, for example, a photointerrupter.

The LSI temperature sensor 3346 constitutes temperature measuring means for detecting the temperature of the control LSI 3311 . For example, the LSI temperature sensor 3346 is composed of an element such as a thermistor, which has resistance-temperature characteristics in which the resistance value changes with changes in temperature, and detects the surface temperature of the control LSI 3311 . The LSI temperature sensor 3346 may be provided on a surface facing away from the mounting surface of the control LSI 3311 (for example, a so-called package surface on which the LSI manufacturer's logo, model, etc. are printed), and may be provided near the control LSI 3311 . may be

Power supply circuit 3302 supplies power to LED light sources 3331R, 3331G, and 3331B via LED driver 3314, as shown in FIG. Although omitted in FIG. 10, the power supply circuit 3302 also supplies power to the intake fan 3342, the exhaust fan 3344, the lens unit 3332, the DMD 3333, and the like.

In this embodiment, the projector device 3300 is configured as a so-called DLP projector. In addition, the projector device 3300 uses the mirror mechanism 3105 to return the irradiation light so as to increase the projection distance to the projection target. ing. As a result, the display unit 3080 including the projector device 3300 is configured to be less expensive and smaller, and can be easily installed in the limited space in the cabinet 3003 of the gaming machine 3001 .

Projector device 3300 constitutes production equipment that executes production. The sub control unit 320U constitutes a control device that controls the projector device 3300. FIG. The graphic board 40 constitutes a video signal output device that outputs a video signal to the projector device 3300 .

The projector control board 3310 and the sub-control board 3200 are capable of bidirectional communication through asynchronous (also called "start-stop synchronization") serial communication. Therefore, both the sub control board 3200 and the projector control board 3310 are provided with serial communication circuits. Hereinafter, the communication line between the projector control board 3310 and the sub control board 3200 is also referred to as a control serial line. The serial communication circuits provided on both the sub-control board 3200 and the projector control board 3310 are configured with circuits for serial communication such as a UART (Universal Asynchronous Receiver Transmitter).

As will be described later, the projector device 3300 and the graphic board 40 are capable of unidirectional communication from the graphic board 40 to the projector device 3300 by differential signals. Hereinafter, the communication line between the projector device 3300 and the graphic board 40 is also referred to as a video serial line.

In this embodiment, the GPU 440 (see FIG. 9) functions as a video signal generating unit that generates a video signal in cooperation with the sub CPU 3201, and also functions as a channel encoding means for channel encoding the video signal. has the function of

For example, when the same value is continuously output to the video signal, the input side produces continuous values as shown in FIG. Inter-symbol interference may occur in which the signal level cannot be maintained or the signal level cannot follow when the same value continues and then becomes a different value.

For this reason, the GPU 440 performs channel encoding on the video signal so that the same value does not continue for more than a predetermined number of bits. As shown in FIG. 13, which will be referred to later, in an AC-coupled high-speed serial interface, intersymbol interference occurs when a DC balance is poor, that is, when five or more consecutive 0s or 1s occur.

Specifically, the GPU 440 performs channel coding conforming to 8b/10b. That is, the GPU 440 refers to a table such as that shown in FIG. 12 and converts an 8-bit (1-byte) symbol (data) in the video signal into a 10-bit symbol.

In the table shown in FIG. 12, when the 8-bit symbol in the video signal is "00", the GPU 440 converts it into a 10-bit symbol of either "1001110100" or "0110001011" by inverting this. do.

In this way, each symbol is assigned to two types of symbols, "Current RD+" and "Current RD-" (hereinafter simply referred to as "RD+" and "RD-", respectively). The GPU 440 alternately selects 'RD+' and 'RD-' for each symbol, thereby prohibiting the same value ('0' or '1') from continuing for 5 or more bits in the video signal.

For example, in the table shown in FIG. 12, when the 8-bit symbol “07” in the video signal continues with “02”, the GPU 440 converts the symbol “07” to “1110001011” of “RD-”. converts the next symbol '02' to '1000101011' in 'RD+'.

On the other hand, in the table shown in FIG. 12, when the 8-bit symbol "07" in the video signal continues with "02", the GPU 440 converts the symbol "07" to "0110010100" of "RD+". , the next symbol “02” is converted to “1011010100” of “RD-”. As a result, the channel-encoded video signal (10-bit symbol) becomes data suitable for an AC-coupled high-speed serial interface, thereby preventing intersymbol interference.

As shown in FIG. 13, the GPU 440 functions as a differential signal transmission driver 110 that converts a video signal into a differential signal and transmits the differential signal. Note that the differential signal in this embodiment conforms to standards such as V-by-One (registered trademark), DisplayPort, and LVDS.

The graphic board 40 is provided with an optical communication module 112 as a transmission (output) module including an electro-optic conversion unit that transmits the differential signal output from the differential signal transmission driver 110 to an optical signal. The optical communication module 112 is AC-coupled with the differential signal transmission driver 110 .

Optical communication module 112 transmits a video signal to optical communication module 114 as a receiving (input) module provided on relay substrate 3301 (see FIG. 10) of projector device 3300 via optical cable 113 as a transmission line.

The optical communication module 114 includes a photoelectric converter that converts the video signal received from the optical cable 113 from an optical signal to a differential signal. A differential signal output from the optical communication module 114 is input to the differential signal reception driver 115 of the projector device 3300 . The differential signal reception driver 115 is AC-coupled with the optical communication module 114 .

In the projector apparatus 3300, a decoding circuit is configured by a control LSI 3311 as transmission path decoding means. The decoding circuit refers to the same table as the table referred to by the GPU 440 (see FIG. 12), and converts the 10-bit symbols in the differential signal into 8-bit symbols.

In this way, the gaming machine 3001 encodes the video signal so that the same value does not continue for more than a predetermined number of bits in the transmission section of the video signal from the graphic board 40 to the relay board 3301. It is possible to prevent the occurrence of inter-symbol interference in which the signal level cannot be held or the signal level cannot follow when the same value becomes different after successive same values.

Projector device 3300 outputs illumination light according to the video signal converted from the differential signal decoded by the decoding circuit, thereby fixing screen mechanism 3120, front screen mechanism 3091, and reel screen mechanism 3130 of screen device 3090 ( (See FIG. 6).

As shown in FIG. 14, the optical communication module 112 provided on the graphic board 40 includes a VCSEL (Vertical Cavity Surface Emitting LASER) driver 120 and a VCSEL 121 as an electro-optic conversion unit. VCSEL driver 120 controls VCSEL 121 to emit light to optical cable 113 according to differential signals Din+ and Din−.

(Outline of pixel shift function)
Next, in projector apparatus 3300, an outline of a pixel shift function in which the optical path of light reflected from DMD 3333 and incident on lens unit 3332 is switched by a switching device will be described.

In this embodiment, after enlarging the original image data, each image of one frame is separated (extracted) into two images, and the separated image data are alternately provided to the DMD 3333 to produce a high-resolution image. is projected onto the fixed screen mechanism 3120 of the screen device 3090, the front screen mechanism 3091, the reel screen mechanism 3130, and the like. The optical path of the light output from the DMD 3333 toward the lens unit 3332 is switched by the switching device 3350 as the separated image data is alternately provided to the DMD 3333 .

FIG. 15 exemplifies an overview of the processing procedure of the pixel shift function when the function is ON at the top. For example, it is assumed here that the resolution of the original image data to be projected onto the screen device 3090 is 1920×1080 pixels. This resolution is called FHD (Full High Definition), and here, this image data is called FHD image data. Also, this FHD image data expresses a moving image, and consists of image images for each frame. Note that the format of general image data representing moving images is not configured to have image image data for each frame, but here, 1920×1080 image image data is prepared for each frame ( expanded).

Next, the FHD image data is enlarged (up-scaling processing) to a resolution of 2560×1440 pixels. This resolution is called WQHD (Wide Quad-HD), and image data of this resolution is called WQHD image data here. A conventional image enlargement algorithm is used to enlarge the FHD image data. For example, the coordinates in the enlarged image are associated with the coordinates (group) in the original image, and the color information (e.g., gradation of each of RGB) on each coordinate of the enlarged image is converted to the corresponding coordinates in the original image. Based on the color information of (group). There are methods such as a bilinear interpolation method and a bicubic interpolation method depending on how to obtain color information.

Next, the WQHD image data is sharpened by a sharpness filter. Sharpening processing using a sharpness filter detects edges in a two-dimensional image and enhances the detected edges to generate a sharp image.

Edge detection is a process of extracting a location where the brightness of an image changes abruptly, and the primary differential is obtained by taking the difference between the target pixel (pixel) and the pixel on the left or right according to the characteristics of the image. A filter, a second-order differential filter, or the like is used for grasping the difference between a target pixel (pixel) and pixels on the top, bottom, left, and right.

Edge enhancement is a process of clarifying a blurred image, and an edge enhancement filter is used, for example, to enhance the density of the nine central pixels. As a result, the central pixel is emphasized and an image with clear edges is generated.

Next, the sharpened WQHD image data is subjected to antialiasing by an alias filter to smooth the edges of the figure represented by the WQHD image data. Anti-aliasing involves identifying pixels (groups) that have abrupt color changes with respect to surrounding pixels (pixels) and converting the color information of the associated pixels into neutral colors so that the colors transition smoothly at their boundaries (edges). , so that the colors transition smoothly (so-called blurring). As a result, jaggies (jaggies of pixels) become less conspicuous and a smooth image can be obtained.

In this embodiment, upscaling processing, sharpening processing, and anti-aliasing processing are sequentially performed in this way. For example, if the FHD image data is displayed after only being subjected to upscaling processing, the image becomes blurred and the displayed image loses consistency. Process the image data to make the part clear. However, simply performing upscaling and sharpening will overemphasize the edges and make the displayed image difficult to see. Makes the displayed image easier to see.

After that, the ODD image data and the EVEN image data are separated (extracted) from the anti-aliased WQHD image data. Here, the ODD image data is image data consisting only of color information related to pixels having odd coordinates X and Y when each pixel of the WQHD image data subjected to anti-aliasing is arranged in a two-dimensional array. show.

That is, in the example shown in FIG. 16, the EVEN image data has coordinates (0, 0), (2, 0), (2558, 0), (0, 2), (2, 2), ( 2558,2), (0,4), (2,4)...(2558,4),...(0,1438), (2,1438)...(2558,1438) is image data consisting of color information related to pixels belonging to an array (here, referred to as an "even array") consisting of the X coordinate and the even Y coordinate of the EVEN image data. It is 1280×720. Pixels belonging to the even array are represented by hatched circular symbols.

FIG. 16 is a diagram schematically showing pixels arranged in an array of 1280×1280 represented by X coordinates (0 to 1279) and Y coordinates (0 to 1279). Color information such as RGB, for example, is stored in association with the pixels. RGB color information includes, for example, 0-255 values for R (red), 0-255 values for G (green), and 0-255 values for B (blue) in the case of 24-bit color. Also, in FIG. 16, display of pixels is omitted for some arrays.

On the other hand, in the example shown in FIG. 16, coordinates (1,1), (3,1)...(2559,1), (1,3), (3,3)...(2559,3), (1,5), (3,5)...(2559,5),...(1,1439), (3,1439)...(2559,1439) odd X coordinates and odd numbers ODD image data is image data consisting of color information related to pixels belonging to an array (here, referred to as an “odd array”) consisting of Y coordinates of , and the number of pixels (resolution) of the ODD image data in this case is It becomes 1280×720, which is the same as the EVEN image data. Pixels belonging to the odd array are represented by white circular symbols.

Further, during such separation processing of the ODD image data and the EVEN image data, each pixel in the ODD image data and the EVEN image data is color-coded based on the color information of a predetermined pixel in the WQHD image data that has undergone anti-aliasing. It is also possible to change color information and perform interpolation processing. In this embodiment, there are a first interpolation process and a second interpolation process, and these interpolation processes will be described later in detail.

As described above, the original image data expresses a moving image, is an image image for each frame (the resolution of each image data is 1920×1080 pixels), and has a frame rate of 30 Hz. This indicates that this image data is displayed at 30 frames per second.

Since the ODD image data and the EVEN image data are extracted from one frame of the original image data, they are displayed at a frame rate of 60 Hz according to the frame rate of the original image data. That is, the ODD image data and the EVEN image data are alternately displayed, the ODD image data is displayed at an interval of 1/30 second, the EVEN image data is also displayed at an interval of 1/30 second, and the ODD image data and the EVEN image data are displayed. The interval at which data is displayed is 1/60 second.

The processing of separating (extracting) the ODD image data and the EVEN image data from the original image data for each frame is performed by the GPU 440 (see FIG. 9) of the graphic board 40 . When the ODD image data and EVEN image data are generated, these image data and the VSYNC signal are transmitted from GPU 440 to projector control board 3310 .

When the DLP control circuit 3313 receives the ODD image data, the EVEN image data, and the VSYNC signal from the GPU 440, it alternately outputs the ODD image data and the EVEN image data to the DMD 3333 according to the timing of the VSYNC signal. , the switching device 3350 according to the timing of the VSYNC signal to alternately switch between the optical path of light based on the ODD image data output from the DMD 3333 and the optical path of light based on the EVEN image data.

Through such control, the light (pixels) based on the ODD image data and the light (pixels) based on the EVEN image data are projected onto the screen device 3090 in a diagonally shifted positional relationship.

FIG. 17(a) shows that when light based on EVEN image data is projected onto the front screen mechanism 3091 or the fixed screen mechanism 3120 of the screen device 3090, for example, the light is projected according to the size of the front screen mechanism 3091 or the fixed screen mechanism 3120. Each pixel of the EVEN image data (1280×720 pixels in this example) is shown displayed on the screen (EVEN image data projection image). Each displayed pixel is schematically represented by a hatched circular symbol as in FIG. The symbol corresponds to 1290×720 pixels, but is shown as 12×6 pixels in FIG. 17(a) for the sake of convenience. These pixels have been shifted by the glass 3352 of the switching device 3350 (see Figure 21).

Next, the light according to the ODD image data is projected onto the front screen mechanism 3091 or the fixed screen mechanism 3120 1/60 second after the projection of the light according to the EVEN image data. Then, each pixel of this ODD image data (1280×720 pixels in this example) is displayed shifted diagonally to the lower right of each pixel of the EVEN image data displayed immediately before.

FIG. 17(b) shows that when the light based on the ODD image data is projected onto the front screen mechanism 3091 or the fixed screen mechanism 3120, each of the ODD image data is projected according to the size of the front screen mechanism 3091 or the fixed screen mechanism 3120. The pixels (1280×720 pixels in this example) are shown displayed on the screen (ODD image data projection image). Each displayed pixel is schematically represented by a white circular symbol as in FIG. The symbol corresponds to 1290×720 pixels, but is shown as 12×6 pixels in FIG. 17(b) for the sake of convenience. These pixels are also shifted by glass 3352 of switching device 3350 (see FIG. 21).

As shown in FIGS. 17A and 17B, 1/60 second after the EVEN image data related to the original image data (first frame) is projected onto the front screen mechanism 3091 or fixed screen mechanism 3120, ODD image data related to the same first frame image data is projected onto the front screen mechanism 3091 or fixed screen mechanism 3120 . After 1/60 second, EVEN image data related to the original image data (second frame) is projected onto the front screen mechanism 3091 or fixed screen mechanism 3120, and after 1/60 second, the image data of the same second frame is projected. Such ODD image data is projected onto the front screen mechanism 3091 or fixed screen mechanism 3120 . Thereafter, similarly, EVEN image data and ODD image data are alternately projected onto the front screen mechanism 3091 or fixed screen mechanism 3120 every 1/60 second along the frame transition of the original image data. Also, here, the original image data is data representing a moving image with a frame rate of 30 Hz.

Further, as can be seen by comparing FIGS. 17(a) and 17(b), a 1280×720 pixel projection image composed of each pixel of the ODD image data is a 1280×720 pixel projection image composed of each pixel of the EVEN image data. It is displayed diagonally to the lower right as a whole with respect to the projected image of 720 pixels.

In this example, the ODD image data pixel P11 representing the pixel at coordinates (1, 1) of the original image data is relative to the EVEN image data pixel P00 representing the pixel at coordinates (0, 0) of the original image data. The pixel P13 of the ODD image data, which is shifted diagonally to the lower right and represents the pixel at the coordinates (1, 3) of the original image data, is the EVEN pixel representing the pixel at the coordinates (0, 2) of the original image data. It is displayed diagonally to the lower right with respect to the pixel P02 of the image data.

FIG. 18(a) makes it easy to understand that each pixel of ODD image data is arranged diagonally to the lower right with respect to each pixel of EVEN image data in projection onto the front screen mechanism 3091 or fixed screen mechanism 3120. FIG. For illustration purposes, each pixel of ODD image data and each pixel of EVEN image data are shown projected simultaneously onto front screen mechanism 3091 or fixed screen mechanism 3120 for convenience.

18(b) is an enlarged view of the upper left position of the front screen mechanism 3091 or fixed screen mechanism 3120 shown in FIG. 18(a). In this example, as described above, the pixel P11 of the ODD image data representing the pixel at coordinates (1, 1) of the original image data is the EVEN image data representing the pixel at coordinates (0, 0) of the original image data. , and the position where the pixel P11 is displayed (display center position) is the display center position of the pixel P00 and the pixel at coordinates (2, 2) of the original image data. and the distance between pixels of adjacent EVEN image data (for example, the distance between the display center position of P00 and the display center position of P20) is PP1. , the display center position of the pixel P11 is displaced from the display center position of the pixel P00 in the diagonally lower right direction by the distance r expressed by the following formula.

Further, since the display center position of the pixel P11 exists at the midpoint between the display center position of the pixel P00 and the display center position of the pixel P22, the distance between the display center position of the pixel P00 and the display center position of the pixel P22 is PP2. Therefore, it can be said that the display center position of the pixel P11 is shifted from the display center position of the pixel P00 in the diagonally lower right direction by a distance of PP2/2. Note that the display center position of the pixel P11 is positioned so as to exist at the middle point between the display center position of the pixel P20 and the display center position of the pixel P02. In this specification, the positional relationship of each pixel of the ODD image data including the pixel P11 is expressed as being at a position (distance/angle) shifted by "half a pixel" from the corresponding pixel of the EVEN image data. do.

In this embodiment, each pixel of the ODD image data is displayed while being shifted diagonally to the lower right direction with respect to the pixels of the EVEN image data. can be controlled to shift to Also, various distances can be selected for the shift distance.

In this way, by alternately projecting the ODD image data and the EVEN image data while shifting them by a predetermined position in the oblique direction, the human eyes can perceive the ODD image data and the EVEN image data, which have a lower resolution than the original image data. Even in the case of projection, it is visually perceived as if the moving image related to the original image data is projected onto the screen at a resolution higher than that of the ODD image data or EVEN image data.

With the configuration of this embodiment, for example, even if the DMD 3333 or other circuits do not have the ability to process high-resolution image data, low-resolution ODD image data and EVEN image data are generated and alternately projected onto the screen. As a result, high-resolution moving images can be represented.

Regarding circuits such as the DMD3333, it takes time and money to develop a new application for high-resolution images, and it will become expensive until a certain scale of manufacturing and sales is achieved. Therefore, the configuration of this embodiment, which can express moving images with higher resolution while using the existing DMD3333 or the like as it is, has a very advantageous effect.

When the pixel shift function as described above is not used (for example, when the pixel shift function is turned off, as shown in the lower part of FIG. 15), the above effects of the present embodiment cannot be obtained, and low resolution Image data is projected onto the screen. That is, the original image data (1920 × 1080 pixels) is reduced to 1280 × 720 pixels (so-called HD (High Definition)) according to the upper limit of resolution that can be processed by the DMD 3333 of this embodiment, and the lens unit 3332 is projected onto the front screen mechanism 3091 of the screen device 3090, the fixed screen mechanism 3120, or the like. The resolution of the image displayed at this time is the resolution of the reduced HD image data (1280×720 pixels), and the frame rate is 30 Hz, which is the same as the original image data.

(Mechanism for realization of pixel shift function)
Next, referring to FIGS. 19 to 22, the optical path is switched by the switching device 3350 between the ODD image data and the EVEN image data, so that each pixel of the EVEN image data is obliquely shown in the lower right direction. Describes how the pixel shift function works, where the pixels of the data are projected.

FIG. 19 shows how DMD 3333 and switching device 3350 are controlled in sub control board 3200 , graphics board 40 , projector control board 3310 and optical mechanism 3330 . Only processing related to optical path switching by the switching device 3350 will be described here.

The sub CPU 3201 of the sub control board 3200 stores, for example, the sub ROM board 42 (see FIG. 9), video data representing a video (moving image) corresponding to the effect. This video data is, for example, FHD image data (original image data) with a resolution of 1920×1080 and 30 fps.

When the sub CPU 3201 of the sub control board 3200 outputs this image data to the GPU 440 of the graphic board 40, the GPU 440 performs image processing as shown in FIG. That is, the GPU 440 enlarges the original image data input from the sub CPU 3201, then performs sharpening processing and anti-aliasing processing on the enlarged image data, and finally generates ODD image data and EVEN image data (separation and separation). Extract. These processes are performed frame by frame, and the frame rate at this time is 60 Hz (the frame rate of the original image data is 30 Hz). The GPU 440 also performs such image processing using the VRAM 441 (see FIG. 9), and the VRAM 441 temporarily stores data necessary for image processing as appropriate. The VRAM 441 is provided with an odd array storage area for storing ODD image data and an even array storage area for storing EVEN image data.

Next, the GPU 440 transmits the generated ODD image data and EVEN image data to the DLP control circuit 3313 of the projector control board 3310 together with the VSYNC signal. The VSYNC signal defines timing for switching between ODD image data and EVEN image data. In this example, the VSYNC signal is 1/60 second (or about 16.6 msec) to alternate (over multiple frames) between ODD and EVEN image data generated from one frame of image data. ) is a timing signal.

The DLP control circuit 3313 alternately outputs the received ODD image data and EVEN image data to the DMD 3333 of the optical mechanism 3330 according to the VSYNC signal.

When the ODD/EVEN signal is input from the sub CPU 3201, the sub control LSI 3316 of the projector control board 3310 controls the optical path switching driver 3335 according to this signal and the VSYNC signal. The switching device 3350 operates to alternately switch projection of ODD image data and EVEN image data based on control of the optical path switching driver 3335 .

FIG. 20 shows the VSYNC signal, the ODD/EVEN signal, the supply of image data (ODD image data and EVEN image data) to the DMD 3333, and the operation timing of the switching device 3350, respectively.

The "VSYNC signal" shown in FIG. 20 is a signal that is output every 16.6 msec (milliseconds), and as described above, this signal indicates the timing of switching between ODD image data and EVEN image data. .

The "ODD/EVEN signal (TTL signal)" shown in FIG. 20 is a signal for determining whether the next frame (the frame at the timing of the next VSYNC signal) is ODD image data or EVEN image data. be.

"Image data" shown in FIG. 20 represents the timing (output timing) at which the ODD image data and EVEN image data output by the GPU 440 are provided to the DMD 3333 by the DLP control circuit 3313, and is synchronized with the VSYNC signal. . Although the output of the ODD image data and the EVEN image data is shown here to take 16.6 msec, they can actually be provided to the DMD 3333 in a shorter time by LVDS.

The “switching device operation” shown in FIG. 20 indicates that the switching device 3350 is in an optical path switching state (ODD state) for projecting ODD image data, an optical path switching state (EVEN state) for projecting EVEN image data, and an ODD state. It indicates which of the states (OFF state) between the state and the EVEN state. The position of the wavy line indicates the OFF state. The control timings of the ODD state and the EVEN state are controlled to synchronize with the VSYNC signal described above, and in synchronization with this timing, the corresponding image data (ODD image data and EVEN image data) are controlled by the DLP control. Provided from circuit 3313 to DMD 3333 .

Here, the sub CPU 3201 controls the ODD/EVEN signal to ODD (High) after a predetermined time (in this example, less than about 1 msec) has passed since the VSYNC signal (arrow A1 in FIG. 20), and then, for example, 10 to 14 ms. It maintains the High state for some time.

The sub control LSI 3316 receives the ODD/EVEN signal from the sub CPU 3201, and if the ODD/EVEN signal is in a High state for 2 to 8 ms, for example, the switching device 3350 is brought out of the EVEN state by the next VSYNC signal (frame). Control is made to transition to the ODD state (arrow A2 in FIG. 20).

With such timing control, when the ODD image data received from the GPU 440 is provided to the DMD 3333, the switching device 3350 switches the ODD image data (at the timing of receiving the next VSYNC signal after the ODD/EVEN signal remains High). Each pixel of the ODD image data is projected onto the front screen mechanism 3091, the fixed screen mechanism 3120, or the like, as controlled by the state. After that, when the ODD image data received from the GPU 440 is provided to the DMD 3333, the switching device 3350 is controlled to the EVEN state at the timing of the next VSYNC signal reception, and each pixel of the EVEN image data becomes (ODD image data is projected onto the front screen mechanism 3091 or fixed screen mechanism 3120 or the like such that each pixel of the image is positioned at a predetermined distance in the diagonal direction from the projected position.

FIG. 21 shows how the glass 3352 of the switching device 3350 is displaced to change the optical path of incident light (light corresponding to each pixel of EVEN image data and ODD image data).

The glass 3352 of the switching device 3350 shown in FIG. 21 is displaced (rotated) by the motor 3351 when the switching device operation shown in FIG. The optical path of the light concerned is switched. Each pixel of the EVEN image data switched in this way is projected onto the front screen mechanism 3091 or the fixed screen mechanism 3120 or the like in the manner shown in FIG. 17(a), for example.

On the other hand, the glass 3352 of the switching device 3350 shown in FIG. 21 is driven by the motor 3351 in the direction opposite to the "EVEN state" when the switching device operation shown in FIG. 20 is controlled to the "ODD state". It is displaced (rotated) to switch the optical path of light for each pixel of the ODD image data. Each pixel of the ODD image data switched in this way is projected onto the front screen mechanism 3091 or fixed screen mechanism 3120 or the like in a manner as shown in FIG. 17(b), for example.

Consequently, when the pixels of the ODD image data are projected onto the front screen mechanism 3091 or the fixed screen mechanism 3120, etc., relative to the projected positions of the pixels of the EVEN image data, (as shown in FIG. 18(b)) It is positioned at a position shifted diagonally to the lower right.

It should be noted that FIG. 21 shows the OFF state of the glass 3352 of the switching device 3350, but this is the state when the pixel shift function is OFF. 3352 can be temporarily in the middle of transition from the EVEN state to the ODD state, or in the middle of transition from the ODD state to the EVEN state. is output to the glass 3352 and is not projected onto the front screen mechanism 3091, fixed screen mechanism 3120, or the like.

FIG. 22 shows the configuration of switching device 3350 . The switching device 3350 has an outermost mounting frame 3357 that fixes the switching device 3350 to the projector apparatus 3300 and rotatably holds one end of the rotating shafts (3356a, 3356b) of the glass 3352 .

Rotating shafts (3356a, 3356b) one end of which is held by the mounting frame 3357 are each fixed to the end of the frame 3355 holding the glass 3352 at the other end. The rotation axes (3356a, 3356b) are arranged at the diagonal corners of the rectangular frame 3355 so that the glass 3352 and the frame 3355 can be displaced (rotated) along the rotation axes.

At least one of the rotating shafts (3356a, 3356b) is connected to a motor 3351 (not shown), and the glass 3352 is alternately displaced around the rotating shaft between the EVEN state and the ODD state by the motor 3351, and each EVEN image is displayed. The optical path of light for data and ODD image data is switched.

(Configuration inside the projector device)
Next, temperature determination regarding DMD 3333 of projector apparatus 3300 will be described. FIG. 23 is a bottom view of the projector device 3300 viewed from below (see FIG. 7(c)). The case 3402 of the projector device 3300 is composed of an upper case 3402a and a lower case 3402b, but here the lower case 3402b is removed and the upper case 3402a is shown below. In addition, vent holes 3404a and 3404b having a plurality of holes are arranged on the side surface of the upper case 3402a.

In the projector apparatus 3300 shown in FIG. 23 from which the lower case 3402b is removed, the fan covers covering the two intake fans (3342a, 3342b) and the two exhaust fans (3344a, 3344b) are removed. , the projector control board 3310 is shown transparently with dotted lines.

Inside the projector device 3300, two intake fans (3342a, 3342b) are arranged. A heat sink 3410a is arranged between one (3342a) of the two intake fans (3342a, 3342b) and the vent 3404a. A heat sink 3410 a is configured to surround a portion of the heat pipe 3411 .

Also, two exhaust fans (3344a, 3344b) are arranged inside the projector device 3300 . A heat sink 3410b is positioned between the two exhaust fans (3344a, 3344b) and the vent 3404b. A heat sink 3410 b is configured to surround a portion of the heat pipe 3411 .

With such a configuration, the two intake fans (3342a, 3342b) and the two exhaust fans (3344a, 3344b) create an air flow from the vent 3404a to the vent 3404b. of heat is released to the outside. Also, the heat collected through the heat pipe 3411 and the like is released to the outside through the air vent 3404b when the heat sinks 3410a and 3410b receive the wind from the intake fan and the exhaust fan described above. Heat from the LED light sources (3331R, 3331G, 3331B), the DMD 3333, the lens unit 3332, the DLP control circuit 3313, etc. is transferred to the heat sinks 3410a and 3410b through the heat pipe 3411 and air. Also, the heat from the LED light sources (3331R, 3331G, 3331B), DMD 3333, lens unit 3332, DLP control circuit 3313, etc. passes through the holding member that holds these members in the projector device 3300 (some of them are heat pipes). 3411) to heat sinks 3410a, 3410b. Therefore, in this case, the heat pipe 3411, the air, and the holding member serve as a heat conduction part that transfers heat from the LED light sources (3331R, 3331G, 3331B), the DMD 3333, the lens unit 3332, the DLP control circuit 3313, etc. to the heat sinks 3410a, 3410b. can catch.

A lens unit 3332 is arranged near the intake fan 3342a. A projection lens of the lens unit 3332 is held by a lens holder 3412 . A lens cover 3413 is attached to the front end of the lens unit 3332 , and a filter 3414 is held in the opening of the lens cover 3413 .

The heat pipe 3411 connects to the heat sink 3410 a on the left side of the projector device 3300 and connects to the heat sink 3410 b on the right side of the projector device 3300 . The heat sink 3410b has a length almost double that of the heat sink 3410a, and the heat sink 3410a corresponds to one intake fan 3342a, and the intake fan 3342a is mainly responsible for the heat dissipation of the heat sink 3410a. , the heat sink 3410b corresponds to two exhaust fans (3344a, 3344b), and these exhaust fans (3344a, 3344b) are generally responsible for the heat dissipation of the heat sink 3410b.

The intake fan 3342b is positioned downstream in the air flow created by the intake fan 3342b, as shown, because there is no corresponding heat sink and the air from the vent 3404a can be drawn in without passing through the heat sink. The DMD 3333 or the like that is in the air can be cooled more effectively.

Heat pipe 3411 extends over the entire longitudinal length of heat sink 3410 a on the left side of projector device 3300 , extends to the bottom of projector device 3300 , bends at the bottom left of projector device 3300 , and extends to the bottom right of projector device 3300 . extends to The heat pipe 3411 further bends at the lower right portion of the projector device 3300 and extends to the upper right portion of the projector device 3300, and is connected to the heat sink 3410b on the right side of the projector device 3300. FIG.

As described above, the DMD 3333 is arranged on the right side (downstream) of the intake fan 3342b, and the DMD heat sink 3417 is held close to this DMD 3333. The optical case 3418 is provided with openings (or transmission portions) through which light emitted from the LED light sources 3331R, 3331G, and 3331B, light emitted to the DMD 3333, and reflected light from the DMD 3333 pass. An opening (or transmission) is provided to provide light to the lens unit 3332 .

The DMD 3333 is connected to the optical case 3418 across the DMD heat sink 3417. The DMD heat sink 3417 is also provided with an opening (or transmission part), and light emitted from the DMD 3333 passes through the DMD heat sink 3417 and the optical case 3418. Provided inside the optical case 3418 through an opening or the like in the case 3418 .

A temperature sensor 3341 d that detects the temperature near the DMD 3333 and outputs a temperature detection signal to the projector control board 3310 is arranged near the switching device 3350 . The temperature sensor 3341d is held, for example, by being placed on the projector control board 3310 at this position. Also, temperature sensor 3341 d may be held at any position near DMD 3333 , eg, any position in spatial region 3416 . In this example, it is held in the projector control board 3310, but it is not limited to this.

A temperature sensor 3341 e that detects the temperature near the lens unit 3332 and outputs a temperature detection signal to the projector control board 3310 is arranged between the intake fan 3342 a and the lens unit 3332 (lens holder 3412 ).

FIG. 24 is a bottom view of a state in which the projector device 3300 is arranged in the irradiation unit 3100 as viewed from below, and is for explaining the air flow in the irradiation unit 3100 and the projector device 3300. FIG. For convenience of explanation, the lower surface 3109 and two duct covers (3421a, 3421b) are removed from the irradiation unit 3100, and the lower case 3402b and the projector control board 3310 are removed from the projector device 3300. shown in the state.

When external air is forcibly taken into the irradiation unit 3100 of the gaming machine 3001 from the intake port 3103 a of the projector cover 3101 by the intake fan 3210 , the taken air flows through the air flow path formed by the projector cover 3101 . (through a space P5 indicated by a dotted line) to a vent 3404a provided in an upper case 3402a of the projector device 3300, and guided into the interior of the projector device 3300. FIG. Such external air intake flows are represented by arrows F1, F2, F3.

The air taken into the projector apparatus 3300 from the air vent 3404a is taken into the projector apparatus 3300 by the intake fan 3342a (FAN4) and the intake fan 3342b (FAN5) in the projector apparatus 3300. FIG.

The air taken into the interior of the projector device 3300 is mainly caused by the air intake fan 3342a (FAN4) and the exhaust fan 3344a (FAN6) (the air flows indicated by arrows H1, H3, H5, and H7). , mainly caused by the intake fan 3342b (FAN5) and the exhaust fan 3344b (FAN7) (airflow indicated by arrows H2, H4, H6, H8), It passes through the interior of the projector device 3300 .

Airflow generated by intake fan 3342a (FAN4) and intake fan 3342b (FAN5) is represented by arrows H1-H4, where heat sink 3410a is positioned upstream of intake fan 3342a (FAN4). (see FIG. 23), the heat sink 3410a is cooled mainly by the airflow (airflow indicated by arrows H1 and H3) generated by the intake fan 3342a (FAN4), and the heat is transferred through the air as a medium. It is sent downstream and further contributes to the exhaust heat of the lens unit 3332 and the like.

On the other hand, no heat sink is arranged upstream of the intake fan 3342b (FAN5). Air having the same temperature as the air temperature is sent downstream, where the air acts as a medium and contributes to the exhaust heat of DMD 3333, switching device 3350 and LED light source 3331 (3331R, 3331G, 3331B).

Thus, since no heat sink is arranged upstream of the intake fan 3342b (FAN5), the intake air (arrow H4) sent by the intake fan 3342b (FAN5) is sent by the intake fan 3342a (FAN4). The temperature is lower than that of air (arrow H3), and the downstream DMD 3333 and LED light source 3331 can be cooled more effectively.

Due to the air flow (arrows H5, H7) mainly generated by the exhaust fan 3344a (FAN6), the upper portion of the heat sink 3410b upstream of the exhaust fan 3344a (FAN6) (the portion corresponding to the position of the exhaust fan 3344a) Heat is exhausted, and the air exhausted by the exhaust fan 3344a (FAN6) is sent to the space P6 formed by the projector cover 3101 and indicated by the dotted line through the air vent 3404b.

On the other hand, due to the air flow (arrows H6, H8) mainly caused by the exhaust fan 3344b (FAN7), the lower side of the heat sink 3410b upstream of the exhaust fan 3344b (FAN7) (corresponding to the position of the exhaust fan 3344b) part) is exhausted, and the air exhausted by the exhaust fan 3344b (FAN7) is sent to the space P6 formed by the projector cover 3101 and indicated by the dotted line through the air vent 3404b.

After that, the air sent to the space P6 is exhausted to the outside from the exhaust port 3103b of the projector cover 3101 by the exhaust fan 3220. FIG. Such flows of air to the outside are indicated by arrows J1, J2, and J3.

By forming two large flow paths as a whole in this way, the air flow passing through the inside of the projector device 3300 is effectively formed, and heat is efficiently exhausted. The airflow passing through the interior of the projector device 3300 cools the optical case 3418 and the DMD 3333 from the surface (outside), and heat accumulated in the heat sink 3410 due to heat conduction through the heat pipe 3411 and the like (for example, the DMD 3333 and heat generated from the LED light sources 3331 (3331R, 3331G, 3331B), etc.). That is, the heat generated in the projector device 3300 is exhausted by the flow of air passing through the projector device 3300 .

It should be noted that the heat sinks 3410a and 3410b in FIG. 23 are simplified diagrams, and in reality, a plurality of heat sinks (for example, about 20 to 30 heat sinks 3410a and about 40 to 60 heat sinks 3410b) are shown. ) are arranged in parallel so as to form a right angle with respect to the length direction of the heat pipe 3411 .

In addition, in this embodiment, as shown in FIG. 23, the air intake fan 3342a (FAN4), the exhaust fan 3344a (FAN6), and the exhaust fan 3344b (FAN7) are adjacent to the upstream side (that is, the left side of FIG. 24). , and a heatsink is provided for each, but the positional relationship between the fan and the heatsink can be reversed left to right. For example, a heat sink 3410a may be provided adjacent to the downstream side (right side in FIG. 24) of the intake fan 3342a (FAN4), or downstream of the exhaust fan 3344a (FAN6) and the exhaust fan 3344b (FAN7). A heat sink 3410b may be provided adjacent to the side.

The intake fan 3210 is an example of an intake means for sending external air. The external air may be taken in indirectly through the flow path, or the external air may be taken in directly and sent to the projector device 3300 . Also, the intake fan 3210 can be omitted.

The exhaust fan 3220 is an example of exhaust means for discharging air to the outside, and such an intake means is formed by the projector cover 3101 of the game machine 3001 like the exhaust fan 3220 of this embodiment. The air may be discharged to the outside indirectly through the air flow path, or the air may be discharged from the projector apparatus 3300 by sending the air directly to the outside. Also, the exhaust fan 3220 can be omitted.

(Pixel shift function by switching device)
Next, the pixel shift function of switching the optical path of light output from DMD 3333 by switching device 3350 will be described with reference to FIG.

FIG. 25 is a diagram showing the internal configuration of the projector device 3300 of this embodiment, and shows some of the components shown in FIG.

In FIG. 25A, light emitted from the LED light sources 3331R, 3331G, and 3331B passes through the switching device 3350 and is incident on the DMD 3333, which is schematically represented by optical paths. That is, the light emitted from the LED light source 3331B is then incident on the switching device 3350 (arrow L) together with the light from the LED light source 3331R (arrow LR) and the light from the LED light source 3331G (arrow LG). At this time, the lights from the LED light sources 3331R, 3331G, and 3331B pass through the switching device 3350 and reach the DMD 3333 (arrow D1). Optical devices such as prisms and mirrors are omitted here.

In FIG. 25(b), based on the light received from the LED light sources 3331R, 3331G, and 3331B and the image data etc. input from the sub CPU 3201, the optical path of the light output from the DMD 3333 is alternately switched by the switching device 3350. The state in which the light is received and is incident on the lens unit 3332 is represented by a schematic optical path. That is, the light output from the DMD 3333 is incident on the switching device 3350 (arrow D2), and when it passes through this switching device 3350, the optical path is changed for a predetermined time ( For example, 1/60 second), and the respectively shifted light is incident on the lens unit 3332 (arrows E1, E2). Optical devices such as prisms and mirrors are omitted here.

Thus, in this embodiment, when the light emitted from the LED light sources 3331R, 3331G, and 3331B is provided to the DMD 3333 via the switching device 3350, and the light from the DMD 3333 is provided to the lens unit 3332, Since the optical path is alternately switched by the switching device 3350, the size of the projector apparatus 3300 can be made compact while projecting a high-resolution image.

(Shutdown temperature setting / DMD temperature peak hold / screen flip function)
Next, the shutdown temperature setting function regarding the projector apparatus 3300, the peak hold function regarding the temperature of the DMD 3333, and the screen reversing function will be described.

The projector device 3300 of the gaming machine 3001 according to this embodiment includes the temperature sensor 3341d that detects the temperature near the DMD 3333, as described above, and the temperature detected by the temperature sensor 3341d and the shutdown temperature Main components of the projector device 3300 are forcibly stopped (forced shutdown). The shutdown temperature can be set from the sub control board 3200, for example.

Further, the projector device 3300 of the gaming machine 3001 according to this embodiment has a function of storing (peak hold) the maximum temperature among the temperatures detected by the temperature sensor 3341d that detects the temperature near the DMD 3333 described above.

Furthermore, the projector device 3300 of the gaming machine 3001 according to the present embodiment has a function of rotating and projecting an image (screen reversing function) in accordance with the gaming machine in which the projector device 3300 is mounted. Also, such image rotation is in accordance with the designation from the sub-control board 3200 . Note that image rotation includes, for example, normal rotation, vertical inversion, horizontal inversion, vertical inversion + horizontal inversion, and the like.

Processing related to each of the above functions will be described with reference to FIGS. 26 to 38. FIG.

FIG. 26 shows projector control main processing by the control LSI 3311 of the projector control board 3310 in the projector device 3300 of the gaming machine 3001 .

As shown in FIG. 26, when the power is turned on, the control LSI 3311 performs projector initialization processing (S2001). This process will be described in detail later with reference to FIG.

Next, the control LSI 3311 determines whether or not the reception completion flag in various flags & work areas of the DRAM is 'ON' (S2002). If the reception completion flag is 'ON' (S2002: Yes), the control LSI 3311 proceeds to the next process of S2003. If the reception completion flag is not 'ON' (S2002: No), the control LSI 3311 proceeds to the process of S2007.

Next, the control LSI 3311 acquires the reception data from the reception storage area of the DRAM (S2003).

Next, the control LSI 3311 sets the various flags of the DRAM and the reception completion flag in the work area to 'OFF' (S2004).

Next, the control LSI 3311 determines whether or not the destination ID of the acquired received data indicates 'projector' (S2005). If the destination ID indicates 'projector' (S2005: Yes), the control LSI 3311 proceeds to the next process of S2006. If the destination ID does not indicate 'projector' (S2005: No), the control LSI 3311 proceeds to the process of S2007.

Next, the control LSI 3311 performs a sub-control-projector reception process (S2006). In the sub-control-projector reception processing, the control LSI 3311 performs various settings for the projector apparatus 3300 according to the command type represented by the reception data acquired in step S2003.

Next, the control LSI 3311 performs projector self-diagnosis processing (S2007). This process will be described in detail later with reference to FIGS. 28 and 29. FIG.

Next, the control LSI 3311 performs processing during transmission between the sub-controller and the projector (S2008). In the sub-control-to-projector transmission processing, the control LSI 3311 creates commands representing various errors of the projector device 3300 and various states of the projector device 3300 as transmission data.

Next, the control LSI 3311 determines whether an LED temperature abnormality (shutdown), FAN rotation abnormality, DMD temperature abnormality, or voltage abnormality is written in the error management area of the DRAM (S2009). An LED temperature abnormality (shutdown) means an LED temperature abnormality that leads to a forced shutdown described later. It is generated and stored when the temperature in the vicinity of any of the LED light sources 3331R, 3331G, and 3331B is detected as being equal to or higher than a predetermined temperature using the associated LED temperature control table.

FAN rotation abnormality means FAN rotation abnormality leading to forced shutdown, and is generated and stored when the rotation speed of any one of FAN4 to FAN7 is detected as being less than a predetermined rotation speed.

The DMD temperature abnormality means a DMD temperature abnormality that leads to a forced shutdown, etc., and is generated and stored when the temperature near the DMD 3333 is equal to or higher than the shutdown temperature (DMD temperature threshold) stored in the DRAM of the control LSI 3311. be. A temperature sensor 3341 d that detects the temperature near the DMD 3333 is arranged downstream of the DMD 3333 in the air flow by the intake fan 3342 and the exhaust fan 3344 and near the DMD 3333 .

A voltage abnormality is generated and stored when, for example, a voltage boost below a predetermined voltage value is detected in the power supplied from the power supply circuit 3302 .

If any of these abnormalities are written in the error management area (S2009: Yes), the control LSI 3311 basically sends an error notification command to the sub CPU 3201 of the sub control board 3200. Go to processing. Error notification processing will be described later. On the other hand, if none of the errors have been written to the error management area (S2009: No), the control LSI 3311 proceeds to the process of S2013.

Next, the control LSI 3311 determines whether or not the sub CPU 3201 of the sub control board 3200 has responded, for example, by sending back a status request command in response to the transmission of the error notification command (S2010). If the sub CPU 3201 responds (S2010: Yes), the control LSI 3311 proceeds to the process of S2012. If the sub CPU 3201 does not respond (S2010: No), the control LSI 3311 proceeds to the process of S2011.

Next, the control LSI 3311 determines whether or not a predetermined time (for example, 30 seconds) has passed after confirming that any abnormality has been written in the error management area of the DRAM (S2011). If the predetermined time has passed (S2011: Yes), the control LSI 3311 proceeds to the process of S2012. If the predetermined time has not elapsed (S2011: No), the control LSI 3311 proceeds to the process of S2013.

Next, the control LSI 3311 transmits a rotation stop command to FAN4, FAN5, FAN6, and FAN7, and a drive stop command to the DLP control circuit 3313 and the LED driver 3314 that drives the LED light sources 3331R, 3331G, and 3331B. Send (S2012). This forcibly shuts down the main operations of the projector device 3300 .

Next, the control LSI 3311 determines whether or not the reset request flag in various flags & work areas of the DRAM is 'ON' (S2013). If the reset request flag is 'ON' (S2013: Yes), the control LSI 3311 proceeds to the next process of S2014. If the reset request flag is not 'ON' (S2013: No), the control LSI 3311 proceeds to the process of S2015.

Next, the control LSI 3311 waits for a reset of the watchdog timer (WDT) (S2014). Waiting for the watchdog timer to be reset means performing infinite loop processing without clearing the watchdog timer (or setting a predetermined value) and waiting for the watchdog timer to output a reset signal to the control LSI 3311. When the timer outputs a reset signal to the control LSI 3311, the control LSI 3311 is reset, thereby restarting the process from the first step (S2001) in the projector control main process (also called "reboot").

In S2015, the control LSI 3311 clears the value of the watchdog timer (WDT).

Next, the control LSI 3311 waits for a period of, for example, 4 msec (S2016). After that, the control LSI 3311 shifts to the process of S2002.

(Projector serial line reception interrupt processing)
FIG. 27 shows projector serial line reception interrupt processing by the control LSI 3311 of the projector control board 3310 . This process is a communication interrupt for fetching received data in response to a request (interrupt signal sent when the serial communication circuit of the control LSI 3311 receives transmission data) via the control serial line during execution of the above-described projector control main process. processing.

As shown in FIG. 27, the control LSI 3311 determines whether the data received from the control serial line is 'STX (02H)' indicating the start of data (S711). If the received data is 'STX' (S711: Yes), the control LSI 3311 proceeds to the next process of S712. If the received data is not 'STX' (S711: No), the control LSI 3311 proceeds to the process of S713.

Next, the control LSI 3311 sets the ETX reception flag and the reception completion flag in the various flags & work areas of the DRAM to 'OFF', and clears the reception storage area (S712). After that, the control LSI 3311 terminates the projector serial line reception interrupt processing.

In S713, the control LSI 3311 stores the data received from the control serial line in the reception storage area of the DRAM.

Next, the control LSI 3311 determines whether or not the received data is 'ETX' indicating the end of the data (S714). If the received data is 'ETX' (S714: Yes), the control LSI 3311 proceeds to the next process of S715. If the received data is not 'ETX' (S714: No), the control LSI 3311 proceeds to the process of S716.

Next, the control LSI 3311 sets various flags in the DRAM and the ETX reception flag in the work area to 'ON' (S715). After that, the control LSI 3311 terminates the projector serial line reception interrupt processing.

In S716, the control LSI 3311 determines whether or not the ETX reception flag in the various flags & work area of the DRAM is 'ON'. If the ETX reception flag is 'ON' (S716: Yes), the control LSI 3311 proceeds to the next process of S717. If the ETX reception flag is not 'ON' (S716: No), the control LSI 3311 terminates the projector serial line reception interrupt process.

Next, the control LSI 3311 performs reception data sum check processing (S717).

Next, the control LSI 3311 determines whether or not the sum value obtained in S717 is normal (S718). If the sum value is normal (S718: Yes), the control LSI 3311 proceeds to the process of S720. If the sum value is not normal (S718: No), the control LSI 3311 proceeds to the next process of S719.

In this embodiment, when determining whether or not the sum value is normal, the control LSI 3311 adds the received data up to 'ETX' excluding 'STX' of the received data, and adds the received data up to 'ETX'. The consistency of the sum value is determined by comparing it with the received data. Note that the calculation method of the sum value is not limited to the addition formula, and a subtraction formula or exclusive OR (also called BCC) may be used.

Next, the control LSI 3311 clears the reception storage area of the DRAM (S719). After that, the control LSI 3311 terminates the projector serial line reception interrupt processing.

In S720, the control LSI 3311 sets the various flags of the DRAM and the reception completion flag in the work area to 'ON'. After that, the control LSI 3311 terminates the projector serial line reception interrupt processing.

Although not shown in FIG. 27, when receiving the received data transmitted by the sub control board 3200 via the control serial line, the control LSI 3311 detects an error in the received data (for example, a framing error, an overrun error, or a parity error). It acquires from a serial communication circuit (not shown) provided on the projector control board 3310 whether any one or more types of errors) have occurred. If so, the control LSI 3311 ends the projector serial line reception interrupt processing without executing steps S711 to S720.

28 and 29 show projector self-diagnosis processing by the control LSI 3311 of the projector control board 3310 in the projector device 3300 of the game machine 3001. FIG.

As shown in FIG. 28, the control LSI 3311 writes, for example, '55AAH' as a diagnostic value read from the ROM to the self-diagnostic storage area of the DRAM by verify check (S2021).

Next, the control LSI 3311 determines whether or not the value (load value) read from the self-diagnostic storage area correctly matches the diagnostic value (S2022). If the load value matches the diagnostic value (S2022: Yes), the control LSI 3311 proceeds to the process of S2024. If the load value does not match the diagnostic value (S2022: No), the control LSI 3311 proceeds to the next process of S2023.

Next, the control LSI 3311 sets 'self-diagnostic abnormality' as error data in the error management area of the DRAM (S2023). This self-diagnostic abnormality includes an error caused by waiting for a reset of a watchdog timer (WDT), which will be described later. When the error information related to the self-diagnostic abnormality including waiting for the WDT reset is set, the control LSI 3311 transmits a command indicating an error notification in the transmission data between the sub control and the projector (S2008) shown in FIG. , sets the reset request flag to 'ON', and then transmits a command indicating the error notification to the sub CPU 3201 of the sub control board 3200 . As a result, the projector initialization process (S2001) shown in FIG. 26 is executed according to the reset signal from the watchdog timer.

Next, the control LSI 3311 performs LED temperature diagnosis processing (S2024). In this process, the control LSI 3311 acquires the LED temperature based on temperature detection signals from the temperature sensors 3341a, 3341b, and 3341c.

Next, the control LSI 3311 determines whether the acquired LED temperature is normal (S2025). If the acquired LED temperature is normal (S2025: Yes), the control LSI 3311 proceeds to the process of S2027. If the acquired LED temperature is not normal (S2025: No), the control LSI 3311 proceeds to the next process of S2026.

Next, the control LSI 3311 sets 'LED temperature abnormality' as error data in the error management area of the DRAM (S2026). Specifically, temperature sensor 3341a, temperature sensor 3341b, and temperature sensor 3341c detect temperatures near LED light sources 3331R, 3331G, and 3331B, respectively. By measuring each temperature through these temperature sensors, the control LSI 3311 determines whether or not the measured temperature is equal to or higher than a predetermined temperature based on the above-described LED temperature control table. Alternatively, error information indicating an abnormality related to forced shutdown is set in the error management area of the DRAM. A warning means a warning display performed before forced shutdown. Forced shutdown controls the operation of main parts such as the LED light sources 3331R, 3331G, and 3331B, FAN4, FAN5, FAN6, and FAN7 of the projector device 3300 due to the temperature and temperature. It means to forcibly stop in response to an abnormality such as the number of revolutions of the fan.

When error information related to such an LED temperature abnormality is set, the control LSI 3311 creates a command indicating an error notification as transmission data in the sub-control-projector transmission processing (S2008) shown in FIG. A command indicating the error notification is transmitted to the sub CPU 3201 of the sub control board 3200 without setting the request flag to 'ON'. As a result, in the projector apparatus 3300, rotation of FAN4, FAN5, FAN6, and FAN7 is stopped, and driving of the DLP control circuit 3313 and LED driver 3314 is stopped (S2012 in FIG. 26). An error display request is made to the device 3023 .

Next, in S2027, the control LSI 3311 detects the maximum LED temperature (LED temperature (MAX)) stored in the EEPROM 3312 of the projector control board 3310 and the corresponding temperature sensor 3341a for the LED light source 3331R. The current temperature (current temperature) near the LED light source 3331R is compared, and if the current temperature is higher than the LED temperature (MAX), the current temperature is stored as the LED temperature (MAX). Such maximum temperature update processing is similarly performed for the LED light sources 3331G and 3331B.

Next, the control LSI 3311 performs fan rotation diagnosis processing (S2028). In this process, the control LSI 3311 acquires the FAN rotation speed based on the fan rotation speed signals from the pulse sensors 3343a, 3343b, 3345a, and 3345b of FAN4, FAN5, FAN6, and FAN7.

Next, the control LSI 3311 determines whether or not the acquired FAN speed is normal (S2029). If the acquired FAN rotation speed is normal (S2029: Yes), the control LSI 3311 proceeds to the process of S2031. If the acquired FAN rotation speed is not normal (S2029: No), the control LSI 3311 proceeds to the next process of S2030.

Next, the control LSI 3311 sets 'fan rotation abnormality' as error data in the error management area of the DRAM (S2030). Specifically, pulse sensors 3343a and 3343b detect the rotation speeds of FAN4 and FAN5, and pulse sensors 3345a and 3345b detect the rotation speeds of FAN6 and FAN7. If any one of FAN4, FAN5, FAN6, and FAN7 is below a predetermined number of revolutions (for example, 4410 rpm) for each number of revolutions, error information indicating an abnormality related to forced shutdown is set in the error management area of the DRAM. do.

When the error information related to the fan rotation speed abnormality is set, the control LSI 3311 creates a command indicating an error notification as transmission data in the sub-control-projector transmission processing (S2008) shown in FIG. A command indicating the error notification is sent to the sub CPU 3201 of the sub control board 3200 without setting the reset request flag to 'ON'. As a result, in the projector apparatus 3300, rotation of FAN4, FAN5, FAN6, and FAN7 is stopped, and driving of the DLP control circuit 3313 and LED driver 3314 is stopped (S2012 in FIG. 26). An error display request is made to the device 3023 .

Next, the control LSI 3311 performs DMD temperature diagnosis processing (S2031). In this process, the control LSI 3311 acquires the DMD temperature based on the temperature detection signal from the temperature sensor 3341d.

Next, the control LSI 3311 determines whether the acquired DMD temperature is normal (S2032). If the obtained DMD temperature is normal (S2032: Yes), the control LSI 3311 proceeds to the process of S2034. If the acquired DMD temperature is not normal (S2032: No), the control LSI 3311 proceeds to the next process of S2033.

Next, the control LSI 3311 sets 'DMD temperature abnormality' as error data in the error management area of the DRAM (S2033). Specifically, temperature sensor 3341 d detects the temperature in the vicinity of DMD 3333 . The control LSI 3311 determines whether the measured temperature is equal to or higher than the shutdown temperature stored in the DRAM of the control LSI 3311 by measuring the temperature through the temperature sensor 3341d. Error information indicating the abnormality is set in the error management area of the DRAM. The shutdown temperature is the default value of 50°C in this example, but can be set between 1°C and 128°C. Furthermore, the DRAM of the control LSI 3311 stores shutdown control execution enable/disable information (information indicating whether to perform forced shutdown control based on the shutdown temperature), and based on this shutdown control execution enable/disable information, sets to the error management area. You can also control whether to do it or not.

When the error information related to the DMD temperature abnormality is set, the control LSI 3311 creates a command indicating an error notification as transmission data in the sub-control-projector transmission processing (S2008) shown in FIG. A command indicating the error notification is transmitted to the sub CPU 3201 of the sub control board 3200 without setting the request flag to 'ON'. As a result, in the projector device 3300, rotation of FAN4 and FAN5 is stopped, and driving of the DLP control circuit 3313 and LED driver 3314 is stopped (S2012 in FIG. 26). A display request is made.

Next, in S2034, the control LSI 3311 controls the highest DMD temperature (DMD temperature (MAX)) stored in the EEPROM 3312 of the projector control board 3310 for the DMD 3333 and the temperature detected by the corresponding temperature sensor 3341d. The current temperature (current temperature) near the DMD 3333 is compared, and if the current temperature is higher than the DMD temperature (MAX), the current temperature is stored as the DMD temperature (MAX).

Next, the control LSI 3311 performs lens temperature diagnosis processing in S2035 of FIG. In this process, the control LSI 3311 acquires the lens temperature based on the temperature detection signal from the temperature sensor 3341e.

Next, the control LSI 3311 determines whether the obtained lens temperature is normal (S2036). If the acquired lens temperature is normal (S2036: Yes), the control LSI 3311 proceeds to the process of S2038. If the acquired lens temperature is not normal (S2036: No), the control LSI 3311 proceeds to the next process of S2037.

Next, the control LSI 3311 sets 'lens temperature abnormality' as error data in the error management area of the DRAM (S2037). Specifically, the temperature sensor 3341 e detects the temperature around the lens unit 3332 . The control LSI 3311 measures the temperature through this temperature sensor to determine whether or not the measured temperature is equal to or higher than a predetermined temperature. , 120° C. to 150° C.) is set in the error management area of the DRAM.

Warning means warning display performed before forced shutdown. Further, control may be performed so that image correction is performed based on the measured temperature. When the temperature of the lens becomes high, the image is distorted. Therefore, it is checked whether or not the image actually projected by the projector device 3300 is distorted, and if the distortion is generated, the distortion is corrected. For example, in response to a setting change request from the projector device 3300, a focus offset command, a focus drift correction value command, and the like are transmitted from the sub control board 3200 to the projector device 3300, and image correction is realized. At this time, the temperature measured by the temperature sensor 3341e is transmitted from the projector device 3300 to the sub-control board 3200, and based on this value, the focus offset command, the focus drift correction value command, etc. may be generated. good.

Forced shutdown means forcibly stopping the main operations of the LED light sources (3331R, 3331G, 3331B) of the projector device 3300, FAN4, FAN5, FAN6, FAN7, etc. according to an abnormality such as temperature or FAN rotation speed. do.

In such a lens temperature diagnosis, when error information indicating an abnormality related to forced shutdown is set, the control LSI 3311 issues a command indicating an error notification in the process (S2008) at the time of transmission between the secondary control and the projector shown in FIG. A command indicating the error notification is sent to the sub CPU 3201 of the sub control board 3200 without setting the reset request flag to 'ON'. As a result, in the projector apparatus 3300, rotation of FAN4, FAN5, FAN6, and FAN7 is stopped, and driving of the DLP control circuit 3313 and LED driver 3314 is stopped (S2012 in FIG. 26). An error display request is made to the device 3023 .

On the other hand, when error information indicating an abnormality related to a warning is set in the lens temperature diagnosis, the control LSI 3311 sends a command indicating an error notification as transmission data in the sub-control-projector transmission processing (S2008) shown in FIG. , and transmits a command indicating the error notification to the sub CPU 3201 of the sub control board 3200 without setting the reset request flag to 'ON'. As a result, the sub-control board 3200 issues an error display request to the sub-liquid crystal display device 3023, but the projector device 3300 repeats normal processing.

Next, in S2038, the control LSI 3311 detects the maximum lens temperature (lens temperature (MAX)) stored in the EEPROM 3312 of the projector control board 3310 and the corresponding temperature sensor 3341e for the lens unit 3332. The current temperature (current temperature) near the lens unit 3332 is compared, and if the current temperature is higher than the lens temperature (MAX), the current temperature is stored as the lens temperature (MAX).

Next, the control LSI 3311 performs projector power diagnosis processing (S2039). In this process, the control LSI 3311 detects the operating voltage of power supplied from the power supply circuit 3302 of the projector device 3300 .

Next, the control LSI 3311 determines whether or not the operating voltage of the projector apparatus 3300 is equal to or higher than the specified voltage (S2040). If the operating voltage of the projector apparatus 3300 is equal to or higher than the specified voltage (S2040: Yes), the control LSI 3311 proceeds to the process of S2042. If the operating voltage of the projector apparatus 3300 is less than the specified voltage (S2040: No), the control LSI 3311 proceeds to the next process of S2041.

Next, the control LSI 3311 sets 'voltage abnormality' as error data in the error management area of the DRAM (S2041). Specifically, for example, voltage abnormality error information indicating an abnormal voltage drop is set. When the error information related to such a voltage abnormality is set, the control LSI 3311 creates a command indicating an error notification as transmission data in the sub-control-projector transmission processing (S2008) shown in FIG. A command indicating the error notification is sent to the sub CPU 3201 of the sub control board 3200 without setting the flag to 'ON'. As a result, in the projector apparatus 3300, rotation of FAN4, FAN5, FAN6, and FAN7 is stopped, and driving of the DLP control circuit 3313 and LED driver 3314 is stopped (S2012 in FIG. 26). An error display request is made to the device 3023 .

Next, the control LSI 3311 performs DLP operation diagnosis processing (S2042). In this process, the control LSI 3311 checks the operation of the DLP control circuit 3313 .

Next, the control LSI 3311 determines whether the operation of the DLP control circuit 3313 is normal (S2043). If the DLP control circuit 3313 operates normally (S2043: Yes), the control LSI 3311 terminates the projector self-diagnosis process. If the operation of the DLP control circuit 3313 is not normal (S2043: No), the control LSI 3311 proceeds to the next process of S2044.

Next, the control LSI 3311 sets 'DLP abnormality' as error data in the error management area of the DRAM (S2044). When error information related to such a DLP abnormality is set, the control LSI 3311 creates a command indicating an error notification as transmission data in the sub-control-projector transmission processing (S2008) shown in FIG. After setting the flag to 'ON', the projector initialization process (S2001) shown in FIG. 32 is executed according to the reset signal from the watchdog timer.

That is, in S2008, the error notification command is created as transmission data, and the reset request flag is set to 'ON'. It is transmitted in S2128 of conversion processing. At this time, the error notification command or information indicating the error notification can also be stored in the EEPROM 3312 . In such a case, commands and information can be retained without being erased even when voltage changes (abnormality due to drop, interruption, rise, etc.) occur due to power failure or restart. After that, the control LSI 3311 terminates the projector self-diagnosis process.

According to such projector control main processing and projector self-diagnostic processing, an error notification command is sent to the sub control board 3200 in response to various abnormalities in the projector apparatus 3300, and the response from the sub control board 3200 at that time is If there is, the circuits and fans of the projector device 3300 are stopped (forced shutdown is performed) according to the abnormality that has occurred. Discomfort of such images is eliminated, and high-quality images with high image visual effects can be safely projected.

Even if there is no response from the sub-control board 3200, after a predetermined period of time, for example, 30 seconds, the operation of the projector device 3300 is automatically shut down. Safe projection of high-definition images is ensured. Note that in the case of a DLP abnormality, that is, in the case of error processing by the watchdog timer, rebooting (initialization processing) is performed, and error transmission is performed after rebooting. In the case of this type of DLP abnormality, there is a high possibility that the projector device 3300 is frozen, and it is difficult to notify the sub CPU 3201 of the sub control board 3200 of the error (for example, the communication status is not normal, the transmission It is assumed that the command or information that should be created cannot be created normally). Therefore, error transmission is executed after reboot. It should be noted that the DLP anomaly may be handled in the same manner as other errors, and error transmission relating to the DLP anomaly may be performed before rebooting.

Further, when the projector apparatus 3300 itself reboots or shuts down, communication with the sub CPU 3201 is not performed for a predetermined time (for example, 1000 ms). A reboot command (or restart) may be issued to the device 3300 . Further, when the sub CPU 3201 cannot receive a signal from the projector apparatus 3300 for a predetermined period of time (for example, 1000 ms), it determines that there is a high possibility that the projector apparatus 3300 is in the process of rebooting. When the sub CPU 3201 fails to receive the incoming error notification command (that is, when a time longer than 1000 ms, for example, 5000 ms elapses), the sub CPU 3201 controls the projector device 3300 to forcibly reboot. Alternatively, an error may be notified.

When the output data of the temperature sensor 3341d is 000h, the DMD temperature is 0.0°C. When the output data is 320h, the DMD temperature is 50°C. When the output data is 7FFh, the DMD temperature is 128°C. be done. However, if the output data of the temperature sensor 3341d is not in the range of 000h to 7FFh (for example, FFCh or 800h indicates a minus temperature), it is treated as 0°C.

In other words, the horizontal position offset and the vertical position offset control which two-dimensional position the projected image is displayed within the projection range, so the projected image can be moved without electric focus adjustment. is. It is also possible to move the focus position by electric focus adjustment, move the horizontal position and vertical position of the projected image during rendering, and change the position of the projected image by software image processing.

In S2100, the sub CPU 3201 determines whether or not the setting change is the pixel shift function setting. If the content of the setting change is pixel shift function setting (S2100: Yes), the sub CPU 3201 proceeds to the next process of S2101. If the setting change is not the pixel shift function setting (S2100: No), the sub CPU 3201 proceeds to the process of S2102.

Next, the sub CPU 3201 performs pixel shift function setting transmission processing (S2101).

When the sub CPU 3201 transmits a command for setting the pixel shift function to the projector control board 3310, the projector control board 3310 stores the pixel shift function setting ("ON" or "OFF") in a predetermined storage means. The sub-control LSI 3316 acquires the stored setting of the pixel shift function via the control LSI 3311, and controls the switching device 3350 according to the acquired setting (“ON” or “OFF”). That is, when the pixel shift function is set to "ON", the sub-control LSI 3316 controls the motor 3351 of the switching device 3350 to alternately rotate the glass 3352 by a predetermined angle at intervals of 1/60 second, The optical path of light from DMD 3333 is alternately changed. On the other hand, when the pixel shift function is set to "OFF", the sub-control LSI 3316 controls the motor 3351 of the switching device 3350 to hold the glass 3352 at a predetermined angle so that the optical path of the light from the DMD 3333 is changed over time. Control so that it does not change over time.

Also, the sub CPU 3201 outputs a command to the GPU 440 to set the frame rate to 60 Hz when the pixel shift function is set to "ON", and the frame rate is set to 60 Hz when the pixel shift function is set to "OFF". A command is output to the GPU 440 so that the frequency becomes 30 Hz.

In S2102, the sub CPU 3201 determines whether the setting change is pixel shift angle setting. If the content of the setting change is pixel shift angle setting (S2102: Yes), the sub CPU 3201 proceeds to the next process of S2103. If the setting change is not the pixel shift angle setting (S2102: No), the sub CPU 3201 ends the projector setting change process.

Next, the sub CPU 3201 performs pixel shift angle setting transmission processing (S2103). In this process, the sub CPU 3201 rewrites the pixel shift angle setting in the projector setting value storage area of the sub RAM board 41 and transmits a command for setting the pixel shift angle to the projector control board 3310 . The setting of the pixel shift angle transmitted to the projector control board 3310 is provided to the sub control board 3200 in advance as data, or is provided to the sub control board 3200 by an input operation on the game machine 3001, for example.

When the sub CPU 3201 sends a command for setting the pixel shift angle to the projector control board 3310, the projector control board 3310 receives the angle information for setting the pixel shift angle (that is, the reference for rotating the glass 3352 of the switching device 3350). angle information) is stored in a predetermined storage means. When the sub control LSI 3316 acquires the angle information of this pixel shift angle setting via the control LSI 3311, it controls the switching device 3350 accordingly. The angle information of the pixel shift angle setting is the reference angle for rotating the glass 3352 of the switching device 3350 .

Such a projector setting change process is basically executed when a maintenance worker at amusement arcade or an inspection worker performs various optical adjustments on the projector device 3300 before shipment from the factory. , the shutdown temperature and shutdown control execution permission/non-execution information can be stored in the DRAM, and can be executed at startup or at any other timing.

In the above description, the shutdown temperature and shutdown control executable information are stored in the DRAM of the projector control board 3310 by the projector setting change process, but these information are initialized by the projector initialization process.

FIG. 32 shows projector initialization processing by the control LSI 3311 of the projector control board 3310 in the projector device 3300 of the gaming machine 3001 .

First, the control LSI 3311 initializes internal functions (S2121). Next, the control LSI 3311 initializes the control serial line (S2122). In this embodiment, in step S2122, the control LSI 3311 sets the baud rate of the control serial line to 38400 bps, sets the data length to 8 bits as the data format in units of 1 byte, and sets the parity to NON (none). . Thus, the control LSI 3311 that executes step S2122 constitutes initialization means.

In S2123, the shutdown temperature and the shutdown control executable/non-executable information are initialized. In this process, the contents of the DRAM of the projector control board 3310 are initialized to a predetermined shutdown temperature and predetermined shutdown control execution availability information. The initial values set in this manner are, for example, (shutdown temperature, shutdown control executable information)=(50° C., OK) or (shutdown temperature, shutdown control executable information)=(-, NO). is.

Next, the control LSI 3311 acquires the horizontal position A adjustment value, the vertical position A adjustment value, the pixel shift function setting (ON/OFF), the angle information of the pixel shift angle setting, and other common settings from the EEPROM 3312 ( S2124).

Next, the control LSI 3311 performs setting control processing for the DLP control circuit 3313 based on the data acquired in S2124 (S2125).

Next, the control LSI 3311 performs setting control processing for the sub-control LSI 3316 based on the data acquired in S2124 (for example, pixel shift function setting (ON/OFF) and angle information for pixel shift angle setting) (S2126). .

Next, the control LSI 3311 acquires the focus adjustment value A (focus on the projection plane of the fixed screen mechanism 3120) from the EEPROM 3312 (S2127).

Next, the control LSI 3311 performs electric focus control processing of the focus mechanism based on the data obtained in S2127 (S2128). Specifically, according to the electric focus control process, a motor drive signal (excitation signal) is output to a focus motor that constitutes the focus mechanism, and the focus is adjusted to the focus position.

Next, the control LSI 3311 initializes various flags and work areas of the DRAM, and self-diagnostic abnormalities (including a reset waiting error of the watchdog timer (WDT)) before this projector initialization processing by rebooting (restarting). or an 'error notification' command indicating DLP abnormality is created, the 'error notification' command is transmitted to the sub CPU 3201 of the sub control board 3200 (S2129). After that, the control LSI 3311 ends the projector initialization process.

In this embodiment, external control means such as the sub-CPU 3201 of the sub-control board 3200 is set so that the shutdown temperature and shutdown control execution propriety information are stored in the DRAM of the projector control board 3310. Such settings can be made by various other external control means.

For example, the main control board MS of the game machine 3001 and other controllers/control means included in the game machine 3001 can function as the external control means. External control means such as the adjustment PC 1000 connected to the projector device 3300 and the secondary relay board SN, and setting control means that can be attached to the projector device 3300 can also function as the external control means.

In this embodiment, as described above, the EEPROM 3312 of the projector control board 3310 stores the DMD temperature (MAX) indicating the maximum DMD temperature after the game machine 3001 is powered on. On the other hand, if the DMD 3333 is placed in a high-temperature environment, the service life of the DMD 3333 is shortened. time) can be determined. Note that the DMD temperature (MAX) stored in the EEPROM 3312 can be reset at the factory or the like, if necessary. The high-temperature environment described above may include a case where the temperature is equal to or higher than the shutdown temperature at which the forced shutdown occurs, and a case where the temperature does not reach the forced shutdown but reaches a certain high temperature.

Further, in the present embodiment, it is possible to determine whether or not the projector device 3300 is recyclable based on the operation time (or power-on time) of the gaming machine 3001 and the DMD temperature (MAX). Here, the operating time can be ascertained by the game machine 3001 storing the energization time of the game machine or the measurement of the operating time by the RTC. , and grasping these values as operating time (or energized time), it is possible to use them as indicators (criteria) for determining whether or not the projector device 3300 is recyclable.

On the other hand, in the present embodiment, whether or not to report the replacement time of the projector device 3300 after being used for a long period of time may be determined based on the criteria for determining whether or not the projector device 3300 is recyclable. Also, although it is common to think that the operating time and the energized time are different times, the DMD 3333 of the projector device 3300 is considered to be always operating when energized. ≅ It is also possible to consider the energization time of the game machine 3001 and the projector device 3300 .

The operation time of the game machine 3001 or the projector device 3300 thus grasped can be configured so as not to be reset from the game machine 3001 or the projector device 3300 .

In this embodiment, as described above, the EEPROM 3312 of the projector control board 3310 stores the screen inversion setting. , “2: horizontal inversion”, and “3: vertical inversion + horizontal inversion” are included.

FIG. 38 shows what kind of image is projected on the screen from the projector device 3300 in accordance with the screen reversal setting described above. FIG. 38(a) shows an original image 3430 represented by original image data, and FIGS. An image projected on a screen virtually provided in front of the device 3300 is shown. In the gaming machine 3001 of this embodiment, the image from the projector device 3300 is reflected by the mirror mechanism 3105 and projected onto the front screen mechanism 3091 or the like. It shall be projected on a virtual screen.

In addition, in the game machine 3001 of the present embodiment, the projector device 3300 is arranged so that the original upper surface faces downward (see FIG. 7(c)), but FIGS. , assume that the projector apparatus 3300 is arranged in its original orientation, which is upside down from this arrangement direction. In addition, in FIGS. 38(b) to 38(e), when the original image 3430 consisting of the letters "ABC" shown in FIG. 38(a) is projected onto the above-described virtual screen, the screen is shown in a transparent view from the opposite side of the projection plane.

Here, in FIG. 38(b), the screen reversal setting of the projector device 3300 is "0: normal rotation", and the original image 3430 shown in FIG. When viewed from the opposite side of the screen projection surface, as shown in image 3430a, the image is viewed as a horizontally inverted image (because it is viewed from the opposite side of the projection surface, the image is horizontally reversed).

In FIG. 38(c), the screen flip setting of the projector device 3300 is "1: upside down", and the original image 3430 shown in FIG. 38(a) is upside down and projected onto the screen projection surface. When viewed from the opposite side of the screen projection surface, as shown in image 3430b, the image is viewed as a horizontally inverted and vertically inverted image (because it is viewed from the opposite side of the projection surface).

In FIG. 38(d), the screen reversal setting of the projector device 3300 is "2: horizontal reversal", and the original image data shown in FIG. 38(a) is horizontally reversed and projected onto the screen projection surface. , when viewed from the opposite side of the screen projection surface, as shown in image 3430c, it is visually recognized as the same image as the original image 3430 (the left-right reversed image is further horizontally reversed because it is viewed from the opposite side of the projection surface). be.

In FIG. 38(e), the screen reversal setting of the projector device 3300 is "3: vertical reversal + horizontal reversal", and the original image 3430 shown in FIG. When viewed from the opposite side of the projection surface of the screen, as shown in image 3430d, (because the image is viewed from the opposite side of the projection surface, the horizontally reversed image is further horizontally reversed) and vertically reversed. It is viewed as an image with

In the gaming machine 3001 of the present embodiment, the projector device 3300 is arranged in the postures shown in FIGS. , the initial value of the screen flip setting is set to "3: flip up/down + flip left/right". In this case, the relationship between the orientation of the projector device 3300, the rotation direction of the original image 3430, the mirror mechanism 3105, and the front screen mechanism 3091 allows the screen reversal setting to be a so-called "Ceiling+Mirror" setting.

The projector control board 3310 of the projector device 3300 controls the direction of rotation when projecting an image based on the screen inversion setting described above. In addition, such image inversion can be realized by, for example, controlling the DMD 3333 by the DLP control circuit 3313, controlling the image signal by the control LSI 3311 or the DLP control circuit 3313, or the like. Also, the projector apparatus 3300 may be a projector that can be selected to rotate an image in at least one of the vertical direction and the horizontal direction.

(VSYNC interrupt processing)
FIG. 33 shows VSYNC interrupt processing by the control LSI 3311 of the projector control board 3310 . This processing is interrupt processing according to the VSYNC signal included in the video signal received via the video serial line during execution of the projector control main processing described above. The control LSI 3311 that executes this VSYNC interrupt processing constitutes synchronous processing means.

In the sub CPU 3201 (see FIG. 9) in this embodiment, the VSYNC interrupt occurs at a cycle of 16.6 msec. A VSYNC signal indicating that a VSYNC interrupt has occurred is included in a video signal (differential signal) from the GPU 440 (see FIG. 9) and sent to the projector control board 3310 of the projector device 3300 . In the projector control board 3310, the DLP control circuit 3313 decodes the video signal sent from the GPU 440 and separates the video data and the VSYNC signal. The separated VSYNC signal is input to the control LSI 3311 as an external interrupt signal, and when the control LSI 3311 accepts the VSYNC signal as an external interrupt signal, it executes VSYNC interrupt processing (see FIG. 19). Also, based on the VSYNC interrupt processing of the control LSI 3311, the sub-control LSI 3316 executes VSYNC interrupt processing (see FIG. 35).

A system CLK (clock), which is the basis of the VSYNC signal generated by the GPU 440, is generated using a highly reliable crystal oscillator. On the other hand, the system CLK of the projector apparatus 3300 is generated by an oscillation circuit (C (capacitor) R (resistor) circuit or L (coil) R (resistor) circuit) provided in the control LSI 3311 constituting the clock generation means. . The time constant (capacitor: F (farad), resistance: Ω (ohm)) of capacitors, resistors, etc. used in the oscillation circuit changes due to heat. Therefore, the time constant of the system CLK of the projector control board 3310 changes due to heat, and the system CLK is likely to deviate due to the change in the time constant.

It should be noted that the main causes of the heat generation that causes the deviation of the system CLK are the heat generated by the LED light sources 3331R, 3331G, and 3331B and the DMD 3333 of the projector device 3300 and the heat generated by the control LSI 3311 itself. The oscillation circuit of the control LSI 3311 becomes hot.

A reception error occurs in the projector control board 3310 and the sub control board 3200 on the receiving side due to a deviation in the system CLK of the projector control board 3310, and the communication response between the projector control board 3310 and the sub control board 3200 decreases. do.

Specifically, the serial communication circuit (not shown) for the control serial line provided on the projector control board 3310 controls the communication speed to a preset communication speed based on the system CLK of the similarly built-in oscillation circuit. there is Therefore, when the system CLK deviates, the communication speed deviates in synchronization with the system CLK deviation. Even if the sub-control board 3200 attempts to receive communication data at a preset communication speed, the communication data is received at a different communication speed from the projector control board 3310, resulting in a phenomenon in which normal reception is not possible. Also, although the communication data transmitted from the sub control board 3200 is transmitted to the projector control board 3310 at a communication speed set in advance from the sub control board 3200, the communication speed of the projector control board 3310 may be deviated. Therefore, the situation is the same as when communication data with a different communication speed is received, and a phenomenon occurs in which communication data cannot be received normally.

The VSYNC interrupt processing described below prevents the communication response between the projector control board 3310 and the sub control board 3200 from deteriorating by suppressing the deviation of the system CLK of the projector control board 3310 .

First, in step S2221 of FIG. 33, the control LSI 3311 acquires the count value of the counter that counts the system CLK of the projector control board 3310 (hereinafter simply referred to as "system CLK count value"). After executing the process of step S2221, the control LSI 3311 executes the process of step S2222.

Specifically, a system CLK oscillated by an oscillation circuit built into the control LSI 3311 is supplied to a CPU (not shown) also built into the control LSI 3311, and the CPU operates with the supplied system CLK. At that time, the supplied system CLK is counted using a 4-byte register in the CPU. The control LSI 3311 acquires the value counted by the register as the system CLK count value in step S2221 of FIG.

In step S2222, the control LSI 3311 stores a count value equal to or greater than 1 ("5" in this embodiment) in CountBuf, which stores the system CLK count value in an area corresponding to the count value of the VSYNC interrupt counter. Store the obtained count value.

The VSYNC interrupt counter counts the number of VSYNC interrupt processing executions, that is, the number of VSYNC receptions. After executing the process of step S2222, the control LSI 3311 executes the process of step S2223.

In step S2223, the control LSI 3311 adds 1 to the VSYNC interrupt counter. After executing the process of step S2223, the control LSI 3311 executes the process of step S2224.

In step S2224, the control LSI 3311 determines whether or not the VSYNC interrupt counter is equal to or greater than 5, which is the number of elements of CountBuf. When determining that the VSYNC interrupt counter is 5 or more (YES), the control LSI 3311 executes the process of step S2225. When determining that the VSYNC interrupt counter is not equal to or greater than 5 (NO), the control LSI 3311 terminates the VSYNC interrupt processing.

In step S2225, the control LSI 3311 sets 0 to the VSYNC interrupt counter. After executing the process of step S2225, the control LSI 3311 executes the process of step S2226.

In step S2226, the control LSI 3311 calculates the average value Av of the difference of CountBuf. When the predetermined number is 5, the CountBuf differences d1 to d4 and their average value Av are calculated based on the following (Equation 1) to (Equation 5).

d1=CountBuf[1]−CountBuf[0] (Formula 1)
d2=CountBuf[2]−CountBuf[1] (Formula 2)
d3=CountBuf[3]−CountBuf[2] (Formula 3)
d4=CountBuf[4]−CountBuf[3] (Formula 4)
Av=(d1+d2+d3+d4)/4 (Formula 5)

After executing the process of step S2226, the control LSI 3311 executes the process of step S2227. In step S2227, the control LSI 3311 calculates an error value by subtracting the reference value from the average value Av.

For example, in this embodiment, the VSYNC interrupt occurs at a cycle of 16.6 msec, and the system CLK of the projector device 3300 is 25 MHz, so the number of reference clocks between VSYNCs is 16.6 msec×25 MHz=415,000.

Therefore, the reference value in this embodiment is set to 415,000. After executing the process of step S2227, the control LSI 3311 executes the process of step S2228.

In step S2228, the control LSI 3311 determines whether the error value is greater than or equal to the lower limit and less than or equal to the upper limit. The lower limit value and the upper limit value are values that allow the communication response between the projector control board 3310 and the sub control board 3200 to be within the allowable range, and the communication specifications of the serial communication circuit (not shown) provided in advance in the sub control board 3200. (communication speed tolerance).

The deviation rate of the baud rate of the control serial line is equal to the deviation rate of the system CLK. That is, if the deviation rate of the system CLK is 1%, the deviation rate of the baud rate of the control serial line is also 1%.

In this embodiment, by suppressing the error in the baud rate of the control serial line to within the range of ±1%, it is possible to prevent the communication response between the projector control board 3310 and the sub control board 3200 from deteriorating. Therefore, the lower limit is set to -4125 and the upper limit is set to 4125.

In step S2228, if the control LSI 3311 determines that the error value is equal to or greater than the lower limit value and equal to or less than the upper limit value (YES), it executes the process of step S2233. If so (NO), the process of step S2229 is executed.

In step S2229, the control LSI 3311 calculates a correction baud rate set value for causing the sub control board 3200 to receive data at a baud rate within the allowable range. Specifically, the control LSI 3311 calculates the corrected baud rate setting value by subtracting the average value of the number of system CLKs between VSYNCs from the product of the baud rate and the reference value.

For example, if the number of system CLKs between VSYNCs is 417038, the control LSI 3311 calculates 38212.35 bps (≈38400 bps×415000/417038) as the correction baud rate set value.

After executing the process of step S2229, the control LSI 3311 executes the process of step S2230. In step S2230, the control LSI 3311 determines whether or not the corrected baud rate setting value calculated in step S2229 is equal to the set baud rate setting value set in the baud rate generator configured by the control LSI 3311.

If it is determined that the calculated corrected baud rate setting value is equal to the set baud rate setting value set in the baud rate generator configured by the control LSI 3311 (YES), the control LSI 3311 terminates the VSYNC interrupt processing. .

If it is determined that the calculated corrected baud rate setting value is not equal to the set baud rate setting value set in the baud rate generator configured by the control LSI 3311 (NO), the control LSI 3311 performs the process of step S2231. Run. In step S2231, the control LSI 3311 sets the correction baud rate setting value to the baud rate generator.

In this way, when the frequency of the system CLK in the projector control board 3310 is higher than the reference value, the setting of the baud rate generator that operates with the clock with this high frequency is corrected to be low, so that the system CLK is transmitted from the projector control board 3310 The transmission data is transmitted at a baud rate (eg, 38400 bps) higher than the actually set baud rate, and the sub control board 3200 receives the data at a baud rate within the allowable range (eg, 38400 bps).

Conversely, when the frequency of the system CLK in the projector apparatus 3300 is lower than the reference value, the transmission data sent from the projector control board 3310 is set higher by correcting the setting of the baud rate generator that operates with a clock with a lower frequency. is transmitted at a baud rate lower than the actually set baud rate (eg, 38400 bps), and the sub control board 3200 receives the data at a baud rate within the allowable range (eg, 38400 bps). In this manner, the control LSI 3311 constitutes communication speed correcting means for correcting the setting of the baud rate generator of the serial communication circuit of the control LSI 3311 according to the frequency of the system CLK.

In other words, if the system clock frequency is higher than the standard, by setting a lower baud rate to the baud rate generator, the baud rate of the actually transmitted communication data will be higher than the set baud rate. If the frequency of the system clock is lower than the standard, by setting the baud rate generator higher, the baud rate of the actually transmitted communication data will be sent at a lower baud rate than the set baud rate. Therefore, a real baud rate different from the set baud rate can be set in the baud rate generator, and the communication speed (baud rate) for transmission and reception with the sub control board 3200 can be kept within the allowable range.

After executing the process of step S2231, the control LSI 3311 executes the process of step S2232. In step S2232, the control LSI 3311 sets ON a baud rate correction flag indicating whether or not the baud rate of the control serial line is in a corrected state. After executing the process of step S2232, the control LSI 3311 terminates the VSYNC interrupt process.

In step S2233, the control LSI 3311 determines whether the baud rate correction flag is ON. When determining that the baud rate correction flag is ON (YES), the control LSI 3311 executes the process of step S2234. When determining that the baud rate correction flag is not ON (NO), the control LSI 3311 terminates the VSYNC interrupt processing.
In step S2234, the control LSI 3311 sets the baud rate value for initialization processing (38400 bps in this embodiment) to the baud rate generator. After executing the process of step S2234, the control LSI 3311 executes the process of step S2235.

That is, when it is determined in step S2228 that the system CLK error value is within the allowable range and the baud rate correction flag is ON, the control LSI 3311 causes the system CLK error value to fall outside the allowable range at least once. , indicates that the corrected baud rate setting value has been set in the baud rate generator, and thereafter the error value of the system CLK has returned to within the allowable range, and the error value of the system CLK has returned to within the allowable range If serial communication with the sub control board 3200 is performed with the corrected baud rate set value in this state, a communication error will occur in both the projector control board 3310 and the sub control board 3200. need to return to

Therefore, after correcting the baud rate generator, the control LSI 3311 performs communication for resetting the baud rate generator of the serial communication circuit of the control LSI 3311 to the baud rate value of the initialization process when the error value of the system CLK falls within the allowable range. Configure speed resetting means.

In step S2235, the control LSI 3311 sets the baud rate correction flag to OFF. After executing the process of step S2235, the control LSI 3311 terminates the VSYNC interrupt process.

In step S2226 of the VSYNC interrupt processing described above, when the control LSI 3311 calculates the average value Av of the difference of the CountBuf, the average value Av is calculated by simple moving average. The average value Av may be calculated by another moving average.

In addition, the simple moving average is to calculate a simple average value for the elements for which the average is calculated, as in the above (Equation 1) to (Equation 5), and the weighted moving average is to calculate the time series For example, in the above (Formula 1) to (Formula 5), d4 of the calculation result is 4 times, d3 is 3 times, d2 is 2 times, and d1 is 1 times The exponential moving average is a calculation method of multiplying the most recent value by a coefficient.

Further, in steps S2228 to S2229 of the VSYNC interrupt processing described above, if the control LSI 3311 determines that the error of the average value of the CountBuf difference with respect to the reference value is outside the allowable range, it calculates the corrected baud rate set value. explained as.

On the other hand, the control LSI 3311 may calculate a corrected baud rate setting value when it determines that the state in which the error of the difference of the CountBuf with respect to the reference value is outside the allowable range continues for a predetermined number of times.

Further, when the control LSI 3311 determines that the number of times that the error of the CountBuf difference with respect to the reference value is outside the allowable range exceeds the upper limit number of times (for example, 3 times) among the specific number of times (for example, 5 times), , the correction baud rate setting value may be calculated.

Further, the control LSI 3311 may calculate a corrected baud rate set value when determining that the error of the difference of the CountBuf with respect to the reference value is out of the allowable range even once.

In addition, the control LSI 3311 acquires the value of the system CLK from the CPU built in the control LSI 3311 via a register. may be used to obtain the value of system CLK.

(Warning due to DMD temperature rise (sub control board))
Next, the function of issuing a warning based on the temperature rise of the DMD 3333 in the sub-control board 3200 of the gaming machine 3001 will be described. As described above, in the amusement machine 3001, in the projector device 3300, an abnormality in the temperature of the DMD 3333 is determined by the projector self-diagnostic process (see FIG. 28). Control was performed to forcibly shut down the main operations of the 3300, but here, various warning screens are displayed under control from the sub-control board 3200 side according to the temperature of the DMD 3333. FIG.

That is, on the sub-control board 3200 side, the temperature of the DMD 3333 (DMD temperature) is acquired from the projector device 3300, and based on the acquired DMD temperature, the projector device 3300 is instructed to irradiate the front screen mechanism 3091 with an image. , a warning screen is displayed on the upper display window 3009 of the game machine 3001, and a warning screen is displayed on the sub liquid crystal display device 3023 by instructing via the sub liquid crystal I/F board SL.

As described above, in the gaming machine 3001 according to the embodiment of the present invention, in the projector control board 3310, the number of clocks generated by the oscillation circuit during the reception time interval of the VSYNC signal is within the allowable range (the error value is the lower limit). value or more and the upper limit value or less), by correcting the baud rate with the sub control board 3200 according to the number of clocks generated by the oscillation circuit during the reception time interval of the VSYNC signal, Since reception errors that occur in the projector control board 3310 and the sub control board 3200 are suppressed, it is possible to prevent the communication response between the projector control board 3310 and the sub control board 3200 from deteriorating.

Also, in the gaming machine 3001 according to the embodiment of the present invention, the moving average of the number of clocks generated by the oscillation circuit during the reception time interval of the VSYNC signal in the projector control board 3310 is within the allowable range (the error value is above the lower limit). and below the upper limit), the baud rate with the sub control board 3200 is corrected according to the moving average of the number of clocks generated by the oscillation circuit during the reception time interval of the VSYNC signal. , suppress reception errors that occur in the projector control board 3310 and the sub control board 3200 .

For this reason, the gaming machine 3001 according to the embodiment of the present invention has the communication speed with the sub-control board 3200 frequently corrected, or the baud rate with the sub-control board 3200 is reduced due to the influence of sporadic noise. can be prevented from being corrected.

In addition, the gaming machine according to the present invention performs transmission path encoding on the video signal so that the same value does not continue for a predetermined number of bits or more in the transmission section of the video signal from the graphic board 40 to the projector device 3300. can be prevented from occurring, or intersymbol interference in which the signal level cannot follow when the same value becomes different after successive same values can be prevented.

In addition, since the gaming machine 3001 according to the embodiment of the present invention converts an electrical signal to be converted into an optical signal and an electrical signal converted from the optical signal into a differential signal having high resistance to noise, noise resistance is improved. can be improved.

In addition, the gaming machine 3001 according to the embodiment of the present invention incorporates the VCSEL driver 120 and the VCSEL 121 for converting video signals from electrical signals to optical signals in the optical communication module 112, and converts video signals from optical signals to electrical signals. By incorporating the PD 122 and the TIA/LA circuit 123 into the optical communication module 114 and transmitting the video signal as an optical signal from the GPU 440 to the projector device 3300, the video signal is prevented from being affected by noise. Therefore, the gaming machine 3001 according to the embodiment of the present invention can improve resistance to noise.

In addition, in the gaming machine 3001 according to the embodiment of the present invention, an example in which the projector device 3300 constitutes the effect device for executing the effect has been described, but the sub liquid crystal display device 3023 may also constitute the effect device.

When the sub-liquid crystal display device 3023 constitutes a production device, the control LSI (not shown) provided in the sub-liquid crystal display device 3023 selectively and adaptively executes various processes that are executed by the control LSI 3311 of the projector device 3300. You should let it run. A detailed description of the effect equipment configured by the sub-liquid crystal display device 3023 is omitted because it can be easily conceived based on the embodiment of the present invention.

(main task)
FIG. 34 shows the main task flow by the sub CPU 3201 of the sub control board 3200 . First, the sub CPU 3201 performs VSYNC interrupt initialization processing for enabling the VSYNC signal to accept interrupts (S2301).

Next, the sub CPU 3201 outputs an ODD/EVEN signal (OFF) (S2302). Here, for the ODD/EVEN signal, "ON" represents "ODD" and "OFF" represents "EVEN". This ODD/EVEN signal is provided to the sub-control LSI 3316 (see FIG. 19).

Next, the sub CPU 3201 sets the ODD/EVEN flag to "OFF" (S2303) and waits for 1 msec (S2304).

In S2305, the sub CPU 3201 determines whether or not the ODD/EVEN flag is "ON". If the ODD/EVEN flag is "ON" (S2305: Yes), the sub CPU 3201 proceeds to the process of S2306. If the ODD/EVEN flag is not "ON" (S2305: No), the sub CPU 3201 proceeds to the process of S2309.

Next, the sub CPU 3201 adds 1 to the ODD_ON counter (S2306). In S2307, the sub CPU 3201 determines whether the ODD_ON counter is 10 or more. If the ODD_ON counter is 10 or more (S2307: Yes), the sub CPU 3201 proceeds to the process of S2308. If the ODD_ON counter is not 10 or more (S2307: No), the sub CPU 3201 proceeds to the process of S2309.

Next, the sub CPU 3201 outputs an ODD/EVEN signal (OFF) (S2308). Next, in S2309, the sub CPU 3201 determines whether or not there is a VSYNC interrupt. If there is a VSYNC interrupt (S2309: Yes), the sub CPU 3201 proceeds to the process of S2310. Note that the VSYNC interrupt occurs every 16.6 msec, and the ODD_ON counter is incremented only when the ODD/EVEN signal, which alternates between ON and OFF at the timing of the VSYNC interrupt, is ON. It is never more than 17 for one interrupt.

If there is no VSYNC interrupt (S2309: No), the sub CPU 3201 returns to the processing of S2304, where it waits for 1 msec again.

In S2310, the sub CPU 3201 outputs image data to the GPU 440 for drawing processing, and then in S2311 resets the watchdog timer (WDT). Rendering processing in the GPU 440 is performed once between two VSYNC interrupts. At this time, ODD image data and EVEN image data are generated from the original image data for one frame (30 Hz), and the ODD image data is generated. is output from the DLP control circuit 3313 to the DMD 3333 at the next VSYNC interrupt timing, and the EVEN image data is output from the DLP control circuit 3313 to the DMD 3333 at the next VSYNC interrupt timing.

Next, the sub CPU 3201 determines in S2312 whether or not the pixel shift function setting is "ON". If the pixel shift function setting is "ON" (S2312: Yes), the sub CPU 3201 proceeds to the process of S2313. If the pixel shift function setting is not "ON" (S2312: No), the sub CPU 3201 returns to the process of S2304, where it again waits for 1 msec.

Next, the sub CPU 3201 determines in S2313 whether or not the ODD/EVEN flag is "OFF". If the ODD/EVEN flag is "OFF" (S2313: Yes), the sub CPU 3201 proceeds to the process of S2314. If the ODD/EVEN flag is not "OFF" (S2313: No), the sub CPU 3201 proceeds to the process of S2317.

Next, sub CPU 3201 outputs an ODD/EVEN signal (ON) (S2314), sets the ODD/EVEN flag to "ON" (S2315), and sets the ODD_ON counter to 0 (S2316). ). After that, the sub CPU 3201 returns to the process of S2304 and waits for 1 msec again there.

In S2317, the sub CPU 3201 sets the ODD/EVEN flag to "OFF", after which the sub CPU 3201 returns to the process of S2304, where it again waits for 1 msec.

Such processing by the main task of the sub CPU 3201 is shown in detail in part of FIG. FIG. 37 shows in more detail one aspect of the timing outlined in FIG. 20, the VSYNC signal, the ODD/EVEN signal, and the ODD/EVEN flag when the pixel shift function is set to ON. , image data (drawing processing), image data output, ODD_ON counter, ODD/EVEN signal monitoring counter, switching device control flag, and switching device operation (motor control) are shown in chronological order.

As shown in FIG. 37, the main task of the sub-CPU 3201 executes a VSYNC interrupt that occurs at a cycle of 16.6 msec and a process that is performed every 1 msec. Start outputting the ODD/EVEN signal at a timing less than 10 msec and continue it for 10 msec. With regard to the timing shown in FIG. 20, the ODD/EVEN signal is maintained at the High state for 10 to 14 msec, but in this example, the ODD/EVEN signal is maintained at the High state for 10 msec.

However, in case the processing is occupied by a task other than the main task of the sub CPU 3201, and the 1 msec wait in S2304 exceeds 1 msec, the ODD/EVEN signal is kept in the High state for about 4 msec for 10 to 14 msec. has a margin of

Furthermore, the ODD/EVEN flag is controlled to alternately turn ON and OFF at timings less than 1 msec from each VSYNC interrupt.

In addition, the GPU 440 performs drawing processing according to the output of image data and an instruction to the GPU 440, and ODD image data and EVEN image data are generated once every two VSYNC interrupts at a timing less than 1 msec after the VSYNC interrupt. be. The main task of the sub CPU 3201 executes processing at a constant cycle of 1 msec, and VSYNC interrupt occurs at a cycle of 16.6 msec. It should be noted that the rendering process also includes commands to the GPU 440 as described above.

Also, since the processing cycles of the sub CPU 2301 and the GPU 440 are not synchronized, a slight delay may occur until the graphics processing of the GPU 440 starts in response to an instruction from the main task of the sub CPU 3201 .

After that, the DLP control circuit 3313 provides ODD image data to the DMD 3333 at the timing of the next VSYNC interrupt of the drawing process, and further provides EVEN image data to the DMD 3333 at the timing of the next VSYNC interrupt.

Furthermore, as shown in FIG. 37, once every two VSYNC interrupts, the ODD_ON counter starts adding 1 at a time less than 1 msec after the VSYNC interrupt, until the ODD/EVEN flag turns OFF. It is added (until it reaches 17 in this example), and then reset to 0 when the ODD/EVEN flag is determined to be OFF at the timing of the VSYNC interrupt.

As described above, in the drawing process of S2310, one process is executed when the VSYNC interrupt occurs twice. By such control, the ODD image data and the EVEN image data are separated from the original image data (30 Hz), and these image data are alternately projected onto the front screen mechanism 3091, the fixed screen mechanism 3120, or the like (60 Hz). . Therefore, the image processing itself is performed every 1/30 second (at 30 fps).

Also, in this example, the switching device 3350 is set to OFF after initialization, but for the sake of processing, the ODD/EVEN signal (OFF) is first output under the control of the sub CPU 3201 (S2302).

As described above, in the drawing process of S2310, one process is executed when the VSYNC interrupt occurs twice. Since the frame rate of the GPU 440 is also changed at the same time, a VSYNC interrupt occurs at a cycle of about 33 msec (30 Hz), and image data drawing processing is performed each time a VSYNC interrupt occurs.

(VSYNC interrupt processing of sub-control LSI)
FIG. 35 shows the flow of VSYNC interrupt processing (external interrupt processing based on the VSYNC signal generated every 16.6 msec) by the sub-control LSI 3316 of the projector control board 3310 . First, in S2331, the sub-control LSI 3316 determines whether or not the pixel shift function setting from the control LSI 3311 is "ON". If the pixel shift function setting from the control LSI 3311 is "ON" (S2331: Yes), the sub-control LSI 3316 proceeds to the process of S2333. The pixel shift function setting from the control LSI 3311 is based on the control from the sub CPU 3201 as described above. If the pixel shift function setting from the control LSI 3311 is not "ON" (S2331: No), the sub-control LSI 3316 proceeds to the process of S2332.

In S2332, the sub-control LSI 3316 controls the motor 3351 of the switching device 3350 to be OFF. Thereby, the glass 3352 of the switching device 3350 irradiates the lens unit 3332 without changing the optical path of the light output from the DMD 3333 when passing through the glass 3352 . After that, the sub-control LSI 3316 returns to the process of S2331. In this example, the motor 3351 of the switching device 3350 is controlled to be turned off each time the VSYNC signal is received. can be done.

Next, the sub-control LSI 3316 determines in S2333 whether or not the switching device control flag is "ODD". If the switching device control flag is "ODD" (S2333: Yes), the sub-control LSI 3316 proceeds to the process of S2334. If the switching device control flag is not "ODD" (S2333: No), the sub-control LSI 3316 proceeds to the process of S2336.

In S2334, the sub-control LSI 3316 controls the motor 3351 of the switching device 3350 to the ODD side to rotate the glass 3352 to a position for shifting the optical path of the light according to the ODD image data. Next, in S2335, the sub-control LSI 3316 sets the switching device control flag to "EVEN" in order to shift the optical path of light according to the next EVEN image data. After that, the sub-control LSI 3316 returns to the process of S2331.

In S2336, the sub-control LSI 3316 controls the motor 3351 of the switching device 3350 to the EVEN side to rotate the glass 3352 to a position for shifting the optical path of light according to the EVEN image data. After that, the sub-control LSI 3316 returns to the process of S2331.

As shown in FIG. 37, by such VSYNC interrupt processing by the sub-control LSI 3316, if the switching device control flag is ODD at the timing of the VSYNC interrupt, the motor 3351 of the switching device 3350 is controlled so that the glass 3352 is ODD. After controlling to be in the state, the switching device control flag is set to EVEN, and if the switching device control flag is EVEN, the motor 3351 of the switching device 3350 is controlled so that the glass 3352 is in the EVEN state.

ODD image data and EVEN image data are provided to the DMD 3333 in synchronization with the transition timing of the ODD state and the EVEN state in the switching device 3350, respectively. Each optical path of light from DMD 3333 by is switched to a corresponding angle by glass 3352 .

(Timer interrupt processing of sub-control LSI)
FIG. 36 shows the flow of timer interrupt processing by the sub-control LSI 3316 of the projector control board 3310 . This processing is periodic interrupt processing executed by a timer interrupt every 1 msec of the built-in timer of the sub-control LSI 3316. At the timing of the timer interrupt, the ODD/EVEN signal is turned from "OFF" to "ON". and transitions from "ON" to "OFF".

First, in S2351, the sub-control LSI 3316 determines whether or not the ODD/EVEN signal has transitioned from "OFF" to "ON". When the ODD/EVEN signal transitions from "OFF" to "ON" (S2351: Yes), the sub-control LSI 3316 proceeds to the process of S2352. If the ODD/EVEN signal has not transitioned from "OFF" to "ON" (S2351: No), the sub-control LSI 3316 proceeds to the process of S2353.

In S2352, the sub-control LSI 3316 sets 0 to the ODD/EVEN signal monitoring counter. After that, the sub-control LSI 3316 ends the timer interrupt processing.

In S2353, the sub-control LSI 3316 determines whether the ODD/EVEN signal is "ON". If the ODD/EVEN signal is "ON" (S2353: Yes), the sub-control LSI 3316 proceeds to the process of S2354. If the ODD/EVEN signal is not "ON" (S2353: No), the sub-control LSI 3316 proceeds to the process of S2355.

Next, the sub-control LSI 3316 adds 1 to the ODD/EVEN signal monitoring counter in S2354. After that, the process proceeds to S2355.

In S2355, the sub-control LSI 3316 determines whether or not the ODD/EVEN signal monitoring counter is 8 or more. If the ODD/EVEN signal monitoring counter is 8 or more (S2355: Yes), the sub-control LSI 3316 proceeds to the process of S2356. If the ODD/EVEN signal monitoring counter is not equal to or greater than 8 (S2355: No), the sub-control LSI 3316 terminates timer interrupt processing.

In S2356, it is determined whether or not the ODD/EVEN signal has changed from "ON" to "OFF". When the ODD/EVEN signal transitions from "ON" to "OFF" (S2356: Yes), the sub-control LSI 3316 proceeds to the process of S2357. If the ODD/EVEN signal has not transitioned from "ON" to "OFF" (S2356: No), the sub-control LSI 3316 terminates timer interrupt processing.

Next, the sub-control LSI 3316 sets the switching device control flag to "ODD" in S2357. . After that, the sub-control LSI 3316 ends the timer interrupt processing.

By such timer interrupt processing by the sub-control LSI 3316, as shown in FIG. When it is ON, it is counted up by 1 at a cycle of 1 msec.

Further, when the ODD/EVEN signal is OFF, it is determined whether or not the ODD/EVEN signal has been kept ON for 8 msec or longer, and the ODD/EVEN signal has been kept ON for 8 msec or longer. , ODD is set in the switching device control flag when the ODD/EVEN signal transitions from ON to OFF. By setting the switching device control flag to ODD, the switching device 3350 is controlled to the ODD state at the timing of the next VSYNC interrupt.

Regarding the timing shown in FIG. 20, when the ODD/EVEN signal continues to be in the High state for 2 to 8 msec, the switching device 3350 is controlled to the ODD state at the timing of the next VSYNC interrupt. , the switching device 3350 is controlled to the ODD state when the ODD/EVEN signal continues to be in the High state for 8 msec.

That is, as described with reference to FIG. 34, the sub CPU 3201 controls the ODD/EVEN signal to be High for 10 msec or longer. Since the sub-control LSI 3316 monitors that the ODD/EVEN signal continues to be in the High state for 8 msec, a margin of 2 msec is provided here, and reliable control is possible.

(Interpolation processing (1) of ODD/EVEN image data in pixel shift function)
Next, the first interpolation processing (see FIG. 15) of ODD/EVEN image data in the pixel shift function will be described with reference to FIGS. 39 and 40. FIG.

As described with reference to FIG. 16, the EVEN image data has coordinates (0,0), (2,0), . . . (2558,0), (0,2), (2,2) (2558, 2), (0, 4), (2, 4) (2558, 4), (0, 1438), (2, 1438) (2558, 1438) ), which is image data consisting of color information related to pixels belonging to an array (even array) consisting of even-numbered X-coordinates and even-numbered Y-coordinates. (3,1)...(2559,1), (1,3), (3,3)...(2559,3), (1,5), (3,5)...(2559 , 5), . It is image data consisting of information.

However, such EVEN image data and ODD image data are only extracted from the original image data (enlarged WQHD image data) with 1/4 number of pixels, respectively, and odd X-coordinates and even-numbered An array of Y coordinates (here, referred to as an “odd array” or “odd array”) and an array of even X coordinates and odd Y coordinates (here, “even-odd array” or “even-odd array”). The image data consisting of the color information for the pixels belonging to the "array" has been lost.

Therefore, in the present embodiment, interpolation processing of the EVEN image data and the ODD image data is performed by reflecting the color information related to the pixels belonging to the even-odd array and the even-odd array in the EVEN image data and the ODD image data. .

FIG. 39 shows even-numbered pixels and odd-numbered pixels similar to those shown in FIG. Pixels that were not reflected (adjacent pixels) are indicated by "*".

FIG. 40 shows a part of FIG. 39 in more detail, and coordinates (0, 0) to (4, 0), (0, 1) to (4, 1), ( 30 belonging to 0,2) to (4,2), (0,3) to (4,3), (0,4) to (4,4), (0,5) to (4,5) are shown schematically.

In the interpolation processing of the present embodiment, for example, for a pixel P33 at coordinates (3, 3) (this is a pixel of ODD image data), the pixels above, below, left and right of this pixel P33, that is, at coordinates (3, 2) pixel D32, pixel D33 at coordinates (3, 4), pixel D23 at coordinates (2, 3), and pixel D43 at coordinates (4, 3). Here, a pixel D32 at coordinates (3, 2) and a pixel D33 at coordinates (3, 4) are pixels belonging to the odd array, and a pixel D23 at coordinates (2, 3) and a pixel D23 at coordinates (4, 3) are pixels belonging to the odd array. The pixel D43 of is a pixel belonging to the even-odd arrangement.

For example, if the color information of each pixel is represented by 8-bit R (red), G (green), and B (blue) (24-bit color), the color information (RGB) of pixel P33 is represented by P33R, P33G, and P33B. , the color information of pixel D32 is represented as D32R, D32G, D32B, the color information of pixel D34 is represented as D34R, D34G, D34B, and the color information of pixel D23 is represented as D23R, D23G, D23B. , the color information of pixel D43 is represented as D43R, D43G, and D43B.

At this time, assuming that the color information of the pixel P33 after the interpolation processing is P33R_N, P33G_N, and P33B_N, the respective color information can be obtained by the following (Equation 6) to (Equation 8).
P33R_N=(P33R+(D32R+D34R+D23R+D43R)/4)/2 (Formula 6)
P33G_N=(P33G+(D32G+D34G+D23G+D43G)/4)/2 (Formula 7)
P33B_N=(P33B+(D32B+D34B+D23B+D43B)/4)/2 (Formula 8)

That is, in this interpolation processing, among the pixels of the original image data (for example, the enlarged WQHD image data) that are not used for projection onto the front screen mechanism 3091, the fixed screen mechanism 3120, or the like, Pixels close to each other such as vertically and horizontally positioned pixels are selected, and the color information of those pixels is reflected in the color information of the pixel to be interpolated at a predetermined ratio. The above interpolation for pixel P33 is for the set of pixels Q2 enclosed in a thick line box indicated by arrow Q2.

In this example, the color information (each RGB value) of the pixel to be interpolated is 50%, and the color information (each RGB value) of the four pixels above, below, left and right is 50% (each pixel is 12.5%). The color information of the new pixel is constructed with the ratio of . Also, here, the values such as "1/4" and "1/2" included in (Equation 6) to (Equation 8) define the addition ratio of each element, and the added RGB value is Coefficients for converting to equivalent color information, referred to herein as "scaling coefficients."

Also, in this example, the ratios (that is, the weight of each element in interpolation) as in the above (Equation 6) to (Equation 8) are applied to the color information of the pixel to be interpolated for the four pixels on the top, bottom, left, and right. Although color information is reflected, any ratio may be used. In addition, the pixels used in the interpolation process are not limited to the four pixels on the top, bottom, left, and right, but may be pixels in the vicinity of the pixel to be interpolated or in a predetermined positional relationship, and the number of pixels used may vary. It is selectable.

Also, in this example, the color information of the four pixels is reflected at an equal rate (12.5%), but the reflection rate may be changed based on a predetermined standard. Further, here, the RGB values are used to perform the interpolation processing by calculations such as the above-mentioned (Equation 6) to (Equation 8), but various other interpolation methods can be selected.

Further, the above example was the interpolation processing for the color information of the pixel P33 included in the ODD image data, but similar interpolation processing can be performed for the color information of the pixel included in the EVEN image data. .

Also, when interpolation processing is performed on a set Q1 of pixels surrounded by a thick line frame indicated by an arrow Q1, the pixels located above, below, left and right of the pixel P00 are only D10 on the right side and D01 on the lower side, but in this case, Assuming that the color information of the pixel P00 after the interpolation processing is P00R_N, P00G_N, and P00B_N, the respective color information can be obtained by the following (equations 9) to (11).

P00R_N=(P00R+(D10R+D01R)/2)/2 (Formula 9)
P00G_N=(P00G+(D10G+D01G)/2)/2 (Formula 10)
P00B_N=(P00B+(D10B+D01B)/2)/2 (Formula 11)

Note that the two "1/2" values included in (Equation 9) to (Equation 11) define the addition ratio of each element, and convert the added RGB values into color information corresponding to one pixel. is the “scaling factor” for

However, the color information of the new pixel P00 obtained in this way may be more influenced by the color information of adjacent pixels than the pixel set Q2 described above. Alternatively, the color information of adjacent pixels that do not exist can be calculated based on the color information of other pixels, and the interpolation processing can be performed using the calculation formulas (Formula 6) to (Formula 8) in the pixel set Q1.

Also, when interpolation processing is performed on a set Q3 of pixels surrounded by a thick line frame indicated by an arrow Q3, the pixels located above, below, left and right of the pixel P04 are D14 on the right lateral side, D03 on the upper side, and D05 on the lower side. However, in this case, if the color information of the pixel P04 after the interpolation processing is P04R_N, P04G_N, and P04B_N, the respective color information can be obtained by the following (Equation 12) to (Equation 14).

P04R_N=(P04R+(D14R+D03R+D05R)/3)/2 (Formula 12)
P04G_N=(P04G+(D14G+D03G+D05G)/3)/2 (Formula 13)
P04B_N=(P04B+(D14B+D03B+D05B)/3)/2 (Formula 14)

The values of "1/3" and "1/2" included in (Equation 12) to (Equation 14) define the addition ratio of each element, and the added RGB value is the color corresponding to one pixel. It is a "scaling factor" for converting to information.

However, the color information of the new pixel P04 obtained in this way may be more influenced by the color information of adjacent pixels than the pixel set Q2 described above. Alternatively, neighboring pixels that do not exist can be calculated based on the color information of other pixels, and interpolation processing can be performed using the calculation formulas (Equation 6) to (Equation 8) in the pixel set Q1.

Such interpolation processing is executed by the GPU 440. For example, after generating (separating and extracting) ODD image data and EVEN image data from the enlarged image data, these data are stored in the VRAM 441 (see FIG. 9). This is done when storing in the odd-numbered array storage area and the even-numbered array storage area.

(Interpolation processing (2) of ODD/EVEN image data in pixel shift function)
Next, the second interpolation processing (see FIG. 15) of ODD/EVEN image data in the pixel shift function will be described with reference to FIGS. 41 and 42. FIG.

FIG. 41 is similar to FIG. 39, but virtual peripheral pixels, which are image data having predetermined color information, are added around the pixels of the effective image data shown in FIG. This is generated as 2562×1442 during the enlargement process described above (see FIG. 15). The virtual peripheral pixels have coordinates (-1,-1) to (2560,-1), coordinates (-1,0) to (-1,1439), coordinates (2560,0) to (2560,1439), coordinates The pixels are arranged in interpolation areas from (-1, 1440) to (2560, 1440), and each pixel is indicated by "◇" and hatched.

Here, after such an interpolation area is provided, the even image data and the odd image data are interpolated by reflecting the color information related to the pixels belonging to the even-odd array and the even-odd array in the even image data and the odd image data. process.

FIG. 42 shows a part of FIG. 40 in more detail. 0), (-1,1) to (4,1), (-1,2) to (4,2), (-1,3) to (4,3), (-1,4) to ( 4,4), 42 pixels belonging to (−1,5) to (4,5) are shown schematically.

In the interpolation processing of this embodiment, for example, for a pixel P00 with coordinates (0, 0) (this is a pixel of EVEN image data), the pixels above, below, left and right of this pixel P00, that is, with coordinates (0, (- 1)) of pixel U0(-1), pixel D01 of coordinates (0,1), pixel U(-1)0 of coordinates ((-1),0), and pixel D10 of coordinates (1,0) Interpolation processing is performed by adding color information. Here, the pixel D01 at coordinates (0, 1) and the pixel D10 at coordinates (1, 0) belong to the odd array, and the pixel U0(-1) at coordinates (0, (-1)) and U0(-1) at coordinates (0, (-1)). , the pixel U(-1)0 at coordinates ((-1),0) belongs to the interpolation area described above.

Pixel P00 with coordinates (0, 0) is located at coordinates (0, 0) in the original image data before the interpolation area is set, and pixels adjacent to the upper and left sides are virtual peripheral pixels. is the corner pixel of .

For example, if the color information of each pixel is represented by 8-bit R (red), G (green), and B (blue) (24-bit color), the color information (RGB) of pixel P00 is represented by P00R, P00G, and P00B. , the color information of pixel D01 is expressed as D01R, D01G, and D01B, the color information of pixel D10 is expressed as D10R, D10G, and D10B, and the color information of pixel U0(-1) is expressed as U0(-1 )R, U0(-1)G, U0(-1)B, and the color information for pixel U(-1)0 is U(-1)0R, U(-1)0G, U(-1 ) 0B.

At this time, if the color information of the pixel P00 after the interpolation processing is P00R_N, P00G_N, and P00B_N, the respective color information is the same as the above (Equation 6) to (Equation 8), and the following (Equation 15) to (Equation 17).
P00R_N=(P00R+(U0(-1)R+D01R+U(-1)0R+D10R)/4)/2 (Formula 15)
P00G_N=(P00G+(U0(-1)G+D01G+U(-1)0G+D10G)/4)/2 (Formula 16)
P00B_N=(P00B+(U0(-1)B+D01B+U(-1)0B+D10B)/4)/2 (Formula 17)

That is, in this interpolation processing, among the pixels of the original image data (for example, the enlarged WQHD image data) that are not used for projection onto the front screen mechanism 3091, the fixed screen mechanism 3120, or the like, It selects pixels that are close to each other, such as vertically and horizontally, and reflects the color information of those pixels on the color information of the pixel to be interpolated at a predetermined ratio. If any of the adjacent pixels located is a virtual peripheral pixel that is not set in the enlarged WQHD image data, color information is calculated taking into account the color information that is set for the virtual peripheral pixel. Also, here, the values such as "1/4" and "1/2" included in (Equation 15) to (Equation 17) define the addition ratio of each element, and the added RGB value is A scaling factor for converting to corresponding color information.

(Other interpolation processing of ODD/EVEN image data in pixel shift function)
Also, for example, in the arrangement of even-numbered pixels and odd-numbered pixels as shown in FIGS. Other methods can also be adopted when interpolation processing is performed taking into consideration the color information of the pixels.

For example, if the color information of each pixel is represented by 8-bit R (red), G (green) and B (blue) (24-bit color), the color information (RGB) of pixel P00 is P00R, P00G, P00B, where the color information of pixel D01 is denoted as D01R, D01G, D01B; the color information of pixel D10 is denoted as D10R, D10G, D10B; Since there is no corresponding pixel for the color information of U(-1)0 (corresponding to a virtual peripheral pixel in the representation of FIG. 41), it is determined as "none" (refer to the thick line frame of arrow Q5 shown in FIG. 42). (see enclosed pixel set Q5).

At this time, assuming that the color information of the pixel P00 after the interpolation processing is P00R_N, P00G_N, and P00B_N, the respective color information can be obtained by the following (equation 18) to (equation 20).
P00R_N=(P00R/2+(D01R+D10R)/8)×(8/6) (Formula 18)
P00G_N=(P00G/2+(D01G+D10G)/8)×(8/6) (Formula 19)
P00B_N=(P00B/2+(D01B+D10B)/8)×(8/6) (Formula 20)

Also, here, the values such as "1/2" and "1/8" included in (Equation 18) to (Equation 20) define the addition ratio of each element, and the added RGB value is A scaling factor for converting to corresponding color information. Furthermore, in this example, the pixel to be interpolated is 4 points, and the adjacent pixels above, below, left and right are 1 point each. If there are not two, then 8-2=6. Next, this total point is expressed as a ratio to the points when all adjacent points exist (=8), and then the reciprocal of this ratio is taken as an interpolation factor.

For example, if there is no neighboring pixel (if one of the pixels positioned above, below, left, and right is a virtual peripheral pixel), the interpolation coefficient is 8/7, and if there are no two neighboring pixels (if If two of the pixels are virtual surrounding pixels), the interpolation factor will be 8/6. The interpolation factor is for converting RGB values into color information corresponding to one pixel, and is one of the scaling factors described above. By providing such interpolation coefficients, it is possible to avoid excessive influence of color information of existing neighboring pixels.

The last coefficient in the calculation formulas for P00R_N, P00G_N, and P00B_N above indicates this interpolation coefficient.

In this way, pixels with interpolation coefficients of 8/7 and 8/6 are pixels located at the edges of the effective image data. For example, in the example shown in FIG. A pixel at 0 as the start point or 2559 as the end point, or a pixel at 0 as the start point or 1439 as the end point in the Y coordinate is a pixel located at the end of the effective image data. In particular, a pixel that is the start point 0 or the end point 2559 on the X coordinate and that is the start point 0 or the end point 1439 on the Y coordinate is a pixel located at a corner of the effective image data. , the interpolation factor for these pixels is 8/6.

Next, an example in which the interpolation coefficient is 8/7 will be described. When interpolation processing is performed on a set Q6 of pixels surrounded by a thick line frame of an arrow Q6 shown in FIG. exists. Note that the pixel P04 at the coordinates (0, 4) is located at the coordinates (0, 4) in the original image data before the interpolation area is set, and is the leftmost pixel that has no adjacent pixel on the left side. be.

In the case of pixels at such positions, if the color information of the pixel P04 after the interpolation processing is P04R_N, P04G_N, and P04B_N, the respective color information can be obtained by the following (Equation 21) to (Equation 23). .
P04R_N=(P04R/2+(D03R+D14R+D05R)/8)×(8/7) (Formula 21)
P04G_N=(P04G/2+(D03G+D14G+D05G)/8)×(8/7) (Formula 22)
P04B_N=(P04B/2+(D03B+D14B+D05B)/8)×(8/7) (Formula 23)

Here, the values such as "1/2" and "1/8" included in (Equation 21) to (Equation 23) define the addition ratio of each element, and the added RGB values correspond to one pixel. A scaling factor for converting to color information. Also, in this case, the interpolation coefficient, which is one of the scaling coefficients, is 8/7 because there is no adjacent pixel. By providing such interpolation coefficients, it is possible to avoid excessive influence of color information of existing neighboring pixels.

Also, when interpolation processing is performed on a set Q7 of pixels surrounded by a thick line frame of an arrow Q7 shown in FIG. However, in this case, if the color information of the pixel P33 after the interpolation processing is P33R_N, P33G_N, and P33B_N, the respective color information can be obtained by the following (Equation 24) to (Equation 26).

P33R_N=(P33R/2+(D32R+D34R+D23R+D43R)/8)×(8/8) (Formula 24)
P33G_N=(P33G/2+(D32G+D34G+D23G+D43G)/8)×(8/8) (Formula 25)
P33B_N=(P33B/2+(D32B+D34B+D23B+D43B)/8)×(8/8) (Formula 26)

Here, values such as "1/2" and "1/8" included in (Equation 24) to (Equation 26) define the addition ratio of each element, and the added RGB values correspond to one pixel. A scaling factor for converting to color information. Also, in this case, the interpolation factor, which is one of the scaling factors, is 8/8 because there are all adjacent pixels. Such an interpolation process is the same as the interpolation result in the first interpolation process when all adjacent pixels are present (see pixel set Q2 in FIG. 40).

In this way, another interpolation process according to this embodiment generates interpolation coefficients according to the number of non-existent adjacent pixels, and interpolates the color information of the pixels. By providing such an interpolation coefficient, the ratio of the color information of the existing adjacent pixels does not become too large with respect to the ratio of the color information of the pixel to be interpolated. Appropriate interpolation can be performed for pixels.

Up to this point, interpolation processing (1), interpolation processing (2), and other interpolation processing of ODD/EVEN image data in the pixel shift function have been described. The number of pixels is not limited to four, and pixels in the vicinity of the pixel to be interpolated or in a predetermined positional relationship can be used, and the number of pixels to be used can also be selected variously. Also, here, the RGB values are used to perform the interpolation processing according to the calculations of the above formulas, but various other interpolation methods can be selected.

In these interpolation processes, the ratio between the color information of the pixel to be interpolated and the color information of each of the adjacent pixels above, below, left and right (that is, the weight of each element during interpolation) is "4:1 interpolation factor ", but this ratio can be changed according to a predetermined condition. Also, different weights can be assigned according to the positions of adjacent pixels.

In yet another interpolation process, if all adjacent pixels are present, a different interpolation method than the interpolation process described above may be used.

Such interpolation processing is executed by the GPU 440. For example, after generating (separating and extracting) ODD image data and EVEN image data from the enlarged image data, these data are stored in the VRAM 441 (see FIG. 9). This is done when storing in the odd-numbered array storage area and the even-numbered array storage area.

(Adjustment of rotation angle of glass in switching device)
The switching device 3350 controls the motor 3351 to rotate the glass 3352 by a predetermined angle according to the control from the sub-control LSI 3316, and alternately between the ODD state and the EVEN state (for example, at intervals of 1/60 second). A transition can be made to alternate the optical path of light from the DMD 3333 .

In this embodiment, external control means such as the sub CPU 3201 of the sub control board 3200 receives angle information that serves as a reference for rotating the glass 3352 of the switching device 3350 and stores it in the EEPROM 3312 of the projector control board 3310 or the like. (See S2102 and S2103 in FIG. 31). Also, such settings can be performed by various other external control means, for example, an external control means such as the projector device 3300 or an adjustment PC 1000 connected to the sub-relay board SN, or the projector device 3300 A setting control means or the like that can be attached to can also function as the external control means.

For example, a maintenance worker in amusement arcade or an inspection worker before shipment from a factory connects the adjustment PC 1000 to the projector device 3300, and an instruction screen displayed on the display of the adjustment PC 1000 opens the glass 3352 of the switching device 3350. Instruct to adjust the rotation angle. The angle specified by such instructions is provided to the optical path switching driver 3335 via the sub-control LSI 3316 .

The switching device 3350 alternately transitions between the ODD state and the EVEN state according to the specified angle to alternately change the optical path of the light from the DMD 3333 so that the maintenance or inspection operator can operate the fixed screen mechanism. 3120 or the like, the ODD state angle and the EVEN state angle are adjusted by viewing the video based on the ODD image data and the EVEN image data. Then, the angle specified there is stored in the EEPROM 3312 of the projector control board 3310 or the like as angle information that serves as a reference when the glass 3352 is rotated.

As the angle information, the rotation angle of the glass 3352 in the ODD state and the rotation angle of the glass 3352 in the EVEN state can be individually designated. Basically, if the reference (OFF state) is 0°, the rotation angle of the glass 3352 in the ODD state is set to +0.16°, and the rotation angle of the glass 3352 in the EVEN state is set to −0.16°. It is A maintenance worker or the like can finely adjust these angles to adjust the rotation angle of the glass 3352 in the ODD state within the range of 0° to +0.176°, and the rotation angle of the glass 3352 in the EVEN state to It can be adjusted in the range of 0° to -0.176°.

Also, the angle information can be set in 128 steps from "0 to 127". Here, the default is "64", 0 to 63 are negative angles, and 65 to 127 are positive angles.

The projection image is confirmed in a state in which the ODD state and the EVEN state alternately transition at the angles adjusted in this way.

[First modification of the embodiment of the present invention]
A first modification of the embodiment of the present invention will be described below with reference to the drawings.

(Projector serial line reception interrupt processing)
FIG. 43 shows a modification of the projector serial line reception interrupt process shown in FIG.

First, in step S801, the control LSI 3311 acquires the status of received data transmitted through the control serial line from a serial communication circuit (not shown) of the control LSI 3311. FIG. After executing the process of step S801, the control LSI 3311 executes the process of step S802.

In step S802, the control LSI 3311 determines whether the received data status is normal. For example, if the status of the received data in the serial communication circuit of the control LSI 3311 indicates that an error such as a framing error, overrun error, or parity error has occurred, the control LSI 3311 determines that the status of the received data is not normal. Thus, the control LSI 3311 that executes step S802 constitutes communication error detection means.

When determining that the status of the received data is not normal (NO), the control LSI 3311 executes the process of step S803. When determining that the status of the received data is normal (YES), the control LSI 3311 executes the process of step S804.

In step S804, the control LSI 3311 executes the projector reception abnormality processing shown in FIG. After executing the process of step S804, the control LSI 3311 ends the projector serial line reception interrupt process.

In step S804, the control LSI 3311 sets 0 to a reception error counter that counts the number of times an error is detected in the reception data from the control serial line. After executing the process of step S804, the control LSI 3311 executes the process of step S805.

The processing of steps S805-S814 is the same as the processing of steps S711-720 in FIG. 27, respectively. Therefore, description of the processing of steps S805 to S814 is omitted.

(VSYNC interrupt processing)
FIG. 44 shows VSYNC interrupt processing executed in place of the VSYNC interrupt processing shown in FIG.

First, in step S2601, the control LSI 3311 acquires the system CLK count value. After executing the process of step S2601, the control LSI 3311 executes the process of step S2602.

In step S2602, the control LSI 3311 queues the system CLK count value in CountBuf. The CountBuf of this modification is composed of a FIFO (First-In First-Out) queue.

As shown in FIG. 45, CountBuf can store a predetermined number N of 1 or more (5 in this modification) of system CLK count values. In FIG. 45, C1-C6 represent system CLK count values, respectively, where C1 represents the first acquired system CLK count value and C6 represents the last acquired system CLK count value.

In the example shown in FIG. 45, the fifth reception of VSYNC fills the CountBuf, and the sixth reception of the VSYNC signal discards the leading (oldest) system CLK count value (C1), leaving the latest system CLK count value (C6) is saved at the end.

Returning to FIG. 44, after executing the process of step S2602, the control LSI 3311 executes the process of step S2603. In step S2603, the control LSI 3311 determines whether the VSYNC interrupt counter is 5 or less.

When determining that the VSYNC interrupt counter is 5 or less (YES), the control LSI 3311 executes the process of step S2604. When determining that the VSYNC interrupt counter is not 5 or less (NO), the control LSI 3311 ends the VSYNC interrupt processing.

In step S2604, the control LSI 3311 adds 1 to the VSYNC interrupt counter. After executing the process of step S2604, the control LSI 3311 terminates the VSYNC interrupt process.

(Projector reception error processing)
FIG. 46 shows the projector reception abnormality processing by the control LSI 3311 of the projector control board 3310 . Although not shown, the projector reception abnormality processing is called before step S2001 of the projector control main processing (see FIG. 26) is executed or before step S2015 is executed. is processed. The control LSI 3311 that executes the projector reception abnormality processing, which will be described below, constitutes error processing means.

First, in step S2611, the control LSI 3311 adds 1 to a reception error counter that counts reception errors from the control serial line. After executing the process of step S2611, the control LSI 3311 executes the process of step S2612.

In step S2612, the control LSI 3311 determines whether the reception error counter is equal to or greater than a predetermined first upper limit number ("8" in this modification) and the VSYNC interrupt counter is equal to or greater than 5, which is the number of elements of CountBuf. determine whether or not

When determining that the reception error counter is 8 or more and the VSYNC interrupt counter is 5 or more (YES), the control LSI 3311 executes the process of step S2613. When determining that the reception error counter is not 8 or more, or the VSYNC interrupt counter is not 5 or more (NO), the control LSI 3311 executes the process of step S2620.

In step S2613, the control LSI 3311 sets 0 to the reception error counter. After executing the process of step S2613, the control LSI 3311 executes the process of step S2614.

In step S2614, the control LSI 3311 calculates the average value Av of the difference of CountBuf. This process is the same as the process of step S2226 of the VSYNC interrupt process shown in FIG. Therefore, the average value Av of the difference of CountBuf is calculated based on the above (formula 1) to (formula 5). After executing the process of step S2614, the control LSI 3311 executes the process of step S2615.

In step S2615, the control LSI 3311 calculates an error value by subtracting the reference value from the average value Av. This processing is the same as the processing of step S2227 of the VSYNC interrupt processing shown in FIG. 33, and the reference value is also the same. After executing the process of step S2615, the control LSI 3311 executes the process of step S2616.

In step S2616, the control LSI 3311 determines whether the error value is greater than or equal to the lower limit and less than or equal to the upper limit. This process is the same as the process of step S2228 of the VSYNC interrupt process shown in FIG. 33, and the lower limit value and upper limit value are also the same.

If the control LSI 3311 determines in step S2616 that the error value is equal to or greater than the lower limit value and equal to or less than the upper limit value (YES), it executes the process of step S2620. If so (NO), the process of step S2617 is executed.

In step S2617, the control LSI 3311 calculates a corrected baud rate setting value for keeping the number of clocks between VSYNCs within the allowable range. This process is the same as the process of step S2229 of the VSYNC interrupt process shown in FIG. After executing the process of step S2617, the control LSI 3311 executes the process of step S2618.

In step S2618, the control LSI 3311 sets the correction baud rate setting value to the baud rate generator. This process is the same as the process of step S2230 of the VSYNC interrupt process shown in FIG. After executing the process of step S2618, the control LSI 3311 executes the process of step S2619.

In step S2619, the control LSI 3311 sets the baud rate correction flag to ON. After executing the process of step S2619, the control LSI 3311 ends the projector reception abnormality process.

In step S2620, the control LSI 3311 determines whether the reception error counter is equal to or greater than a predetermined second upper limit number ("5" in this modification) and whether the baud rate correction flag is ON.

When determining that the reception error counter is 5 or more and the baud rate correction flag is ON (YES), the control LSI 3311 executes the process of step S2621. If it is determined that the reception error counter is not 5 or more or the baud rate correction flag is not ON (NO), the control LSI 3311 terminates the projector reception abnormality processing.

In step S2621, the control LSI 3311 calculates the average value Av of the difference of CountBuf. Note that this process is the same as the process in step S2614. After executing the process of step S2621, the control LSI 3311 executes the process of step S2622.

In step S2622, the control LSI 3311 calculates an error value by subtracting the reference value from the average value Av. This process is the same as the process in step S2615. After executing the process of step S2622, the control LSI 3311 executes the process of step S2623.

In step S2623, the control LSI 3311 determines whether the error value is greater than or equal to the lower limit and less than or equal to the upper limit. This process is the same as step S2616. Note that the lower limit value and the upper limit value may differ from the lower limit value and the upper limit value in step S2616, respectively.

If the control LSI 3311 determines in step S2623 that the error value is equal to or greater than the lower limit value and equal to or less than the upper limit value (YES), it executes the process of step S2624. If so (NO), the projector reception abnormality processing is terminated.

In step S2624, the control LSI 3311 sets the baud rate before correction, that is, the baud rate value of the initialization process (projector initialization process shown in FIG. 32) to the baud rate generator. After executing the process of step S2624, the control LSI 3311 executes the process of step S2625.

In step S2625, the control LSI 3311 sets 0 to the reception error counter. After executing the process of step S2625, the control LSI 3311 executes the process of step S2626.

In step S2626, the control LSI 3311 sets the baud rate correction flag to OFF. After executing the process of step S2626, the control LSI 3311 ends the projector reception abnormality process.

In this manner, the control LSI 3311 corrects the baud rate when reception errors occur continuously for the first upper limit number of times or more. However, if the system CLK error is within the permissible range, the control LSI 3311 does not correct the baud rate because it is considered that the reception error is caused by factors other than the deviation of the frequency of the system CLK from the baud rate.

Further, after the execution of the baud rate correction, the control LSI 3311 determines whether or not the error of the system CLK is within the allowable range when the reception error occurs more than the second upper limit number of times in succession.

If the system CLK error is within the allowable range, it is considered that a reception error has occurred due to correction of the baud rate, so the control LSI 3311 returns the baud rate to the initial value. In other cases, the control LSI 3311 does not reset the baud rate to the initial value because it is considered that a reception error has occurred due to factors other than the correction of the baud rate.

In the first modified example, if the reception error occurs more than the first upper limit number of times in succession, the baud rate is corrected. The reason for this is to prevent the baud rate value from being changed when a reception error occurs due to noise or the like.

If it is determined that the error value is less than the lower limit value or greater than the upper limit value (NO) in step S2623 of the projector reception abnormality processing, the control LSI 3311 may correct the baud rate again.

In this case, if the control LSI 3311 determines in step S2623 that the error value is less than the lower limit value or greater than the upper limit value (NO), it performs the same processing as in step S2617 to calculate the corrected baud rate value. If the corrected baud rate set value obtained is different from the set corrected baud rate set value, the same processing as in step S2618 is executed, and the projector reception abnormality processing ends.

Further, in steps S2614 and S2621 of the projector reception abnormality processing described above, when the control LSI 3311 calculates the average value Av of the difference of the CountBuf, the average value Av is calculated by simple moving average. The average value Av may be calculated by another moving average such as a smooth moving average.

Further, in steps S2616 and S2617 of the projector reception abnormality processing described above, if the control LSI 3311 determines that the error of the average value of the difference of the CountBuf with respect to the reference value is out of the allowable range, the correction baud rate setting value is calculated. described as what to do.

On the other hand, when the control LSI 3311 determines that the state in which the error of the difference of the CountBuf with respect to the reference value is outside the allowable range continues for a predetermined number of times (for example, three times), the average value of the predetermined number of times is further averaged. value or the most recent average value may be used to calculate the corrected baud rate setting.

Further, when the control LSI 3311 determines that the number of times that the error of the CountBuf difference with respect to the reference value is outside the allowable range exceeds the upper limit number of times (for example, 3 times) among the specific number of times (for example, 5 times), , the correction baud rate setting value may be calculated.

Further, the control LSI 3311 may calculate a corrected baud rate set value when determining that the error of the difference of the CountBuf with respect to the reference value is out of the allowable range even once.

In steps S2623 and S2624 of the projector reception abnormality processing described above, if the control LSI 3311 determines that the error of the average value of the difference of the CountBuf with respect to the reference value is within the allowable range, the baud rate generator is initialized. was explained as setting the baud rate value of

On the other hand, if the control LSI 3311 determines that the state in which the error of the CountBuf difference with respect to the reference value is within the allowable range continues for a predetermined number of times (for example, twice), the baud rate generator 3311 outputs the baud rate value for initialization processing. may be set.

Further, when the control LSI 3311 determines that the number of times that the error of the CountBuf difference with respect to the reference value is within the allowable range is equal to or greater than the upper limit number of times (for example, 3 times) among the specific number of times (for example, 5 times), , a baud rate value for initialization processing may be set in the baud rate generator.

If the control LSI 3311 determines that the error of the CountBuf difference with respect to the reference value is within the allowable range even once, it may set the baud rate value for the initialization process to the baud rate generator.

As described above, in the gaming machine 3001 according to the present modification, in a state where an error in communication with the sub-control board 3200 is detected in the projector device 3300, the VSYNC signal is generated during the reception time interval. If the number of clocks is outside the allowable range (the error value is greater than or equal to the lower limit and less than or equal to the upper limit), the number of clocks generated during the reception time interval of the VSYNC signal determines the number of clocks generated. By correcting the baud rate, reception errors that occur in the projector control board 3310 and the sub control board 3200 are suppressed. can.

[Second modification of the embodiment of the present invention]
A second modification of the embodiment of the present invention will be described below with reference to the drawings.

(VSYNC interrupt processing)
The VSYNC interrupt processing in the second modification of the embodiment of the invention is the same as the VSYNC interrupt processing in the first modification of the embodiment of the invention (see FIG. 44). Therefore, description of VSYNC interrupt processing in the second modification of the embodiment of the present invention is omitted.

(Surface temperature diagnosis processing)
FIG. 47 shows surface temperature diagnosis processing by the control LSI 3311 of the projector control board 3310 . A control LSI 3311 that executes the surface temperature diagnosis processing described below constitutes temperature processing means.

The surface temperature diagnosis process is executed in the projector self-diagnosis process shown in FIGS. 28 and 29. For example, in step S2043 of FIG. After executing the processing of step S2044, the control LSI 3311 executes the surface temperature diagnosis processing described below.

In step S2651 of FIG. 47, the control LSI 3311 acquires measurement data, that is, data representing the surface temperature of the control LSI 3311 from the LSI temperature sensor 3346 (see FIG. 10). After executing the process of step S2651, the control LSI 3311 executes the process of step S2652.

In step S2652, the control LSI 3311 determines that the temperature represented by the data acquired from the LSI temperature sensor 3346 in step S2651 (hereinafter simply referred to as "LSI temperature") is less than the first lower threshold or exceeds the first upper threshold ( That is, it is determined whether the temperature is outside the first allowable temperature range) and the VSYNC interrupt counter is 5 or more.

The first lower threshold and the first upper threshold are appropriately set based on the guaranteed operation value of the system CLK of the projector device 3300 . In this modified example, the first lower limit threshold is set to 5°C, and the first upper limit threshold is set to 60°C.

When determining that the LSI temperature is outside the first allowable range and that the VSYNC interrupt counter is 5 or more (YES), the control LSI 3311 executes the process of step S2653. If it is determined that the LSI temperature is not outside the first allowable range or the VSYNC interrupt counter is not 5 or more (NO), the control LSI 3311 executes the process of step S2660.

In step S2653, the control LSI 3311 determines whether the baud rate correction flag is ON. When determining that the baud rate correction flag is ON (YES), the control LSI 3311 executes the process of step S2654. When determining that the baud rate correction flag is not ON (NO), the control LSI 3311 executes the process of step S2660.

In step S2654, the control LSI 3311 calculates the average value Av of the difference of CountBuf. This process is the same as the process of step S2226 of the VSYNC interrupt process shown in FIG. Therefore, the average value Av of the difference of CountBuf is calculated based on the above (formula 1) to (formula 5). After executing the process of step S2654, the control LSI 3311 executes the process of step S2655.

In step S2655, the control LSI 3311 calculates an error value by subtracting the reference value from the average value Av. This processing is the same as the processing of step S2227 of the VSYNC interrupt processing shown in FIG. 33, and the reference value is also the same. After executing the process of step S2655, the control LSI 3311 executes the process of step S2656.

In step S2656, the control LSI 3311 determines whether the error value is greater than or equal to the lower limit and less than or equal to the upper limit. This process is the same as the process of step S2228 of the VSYNC interrupt process shown in FIG. 33, and the lower limit value and upper limit value are also the same.

If the control LSI 3311 determines in step S2656 that the error value is equal to or greater than the lower limit value and equal to or less than the upper limit value (YES), it executes the process of step S2660. If so (NO), the process of step S2657 is executed.

In step S2657, the control LSI 3311 calculates a correction baud rate set value for keeping the number of clocks between VSYNCs within the allowable range. This process is the same as the process of step S2229 of the VSYNC interrupt process shown in FIG. After executing the process of step S2657, the control LSI 3311 executes the process of step S2658.

In step S2658, the control LSI 3311 sets the correction baud rate setting value to the baud rate generator. This process is the same as the process of step S2230 of the VSYNC interrupt process shown in FIG. After executing the process of step S2658, the control LSI 3311 executes the process of step S2659.

In step S2659, the control LSI 3311 sets the baud rate correction flag to ON. After executing the process of step S2659, the control LSI 3311 terminates the surface temperature diagnosis process.

In step S2660, the control LSI 3311 determines whether the LSI temperature is equal to or higher than the second lower limit threshold and equal to or lower than the second upper limit threshold (that is, within the second allowable temperature range). The second lower limit threshold and the second upper limit threshold are appropriately set based on the operation guarantee value of the system CLK of the projector device 3300 .

In this modification, the second lower threshold is set at 15° C., which is higher than the first lower threshold, and the second upper threshold is set at 40° C., which is lower than the first upper threshold. That is, the second allowable temperature range is a temperature zone called room temperature and is set to be included in the first allowable temperature range.

If it is determined in step S2660 that the LSI temperature is within the second allowable range (YES), the control LSI 3311 executes the process of step S2661. When determining that the LSI temperature is not within the second allowable range (NO), the control LSI 3311 terminates the surface temperature diagnosis process.

In step S2661, the control LSI 3311 determines whether or not the baud rate is the initial value (the value at the time of the projector initialization processing shown in FIG. 32). When determining that the baud rate is not the initial value (NO), the control LSI 3311 executes the process of step S2662. When determining that the baud rate is the initial value (YES), the control LSI 3311 terminates the surface temperature diagnosis process.

In step S2662, the control LSI 3311 sets the baud rate before correction, that is, the baud rate value of the initialization process (projector initialization process shown in FIG. 32) to the baud rate generator. After executing the process of step S2662, the control LSI 3311 executes the process of step S2663.

That is, when the LSI temperature returns to normal temperature within the second allowable range, the oscillation circuit of the control LSI 3311 also outputs system CLK of a normal frequency. must be set to the baud rate value set in the projector initialization process.

In step S2663, the control LSI 3311 sets the baud rate correction flag to OFF. After executing the process of step S2663, the control LSI 3311 terminates the surface temperature diagnosis process.

In step S2661 of the surface temperature diagnosis process described above, the control LSI 3311 may determine whether or not the baud rate correction flag is ON. In this case, if the control LSI 3311 determines that the baud rate correction flag is ON (YES), it executes the process of step S2662, and if it determines that the baud rate correction flag is not ON (NO), the surface temperature End diagnostic processing.

Thus, if the system CLK error is within the allowable range, the control LSI 3311 is likely to operate normally even if the LSI temperature is outside the first allowable range. do not have.

Further, if the LSI temperature falls within the second allowable range after the baud rate is corrected, the control LSI 3311 sets the baud rate value for the initialization process to the baud rate generator, thereby allowing the system to operate with the baud rate corrected from the initial value. Since the frequency of CLK has become normal, the occurrence of reception errors is suppressed.

If it is determined that the LSI temperature is not within the second allowable range (NO) in step S2660 of the surface temperature diagnosis process described above, the control LSI 3311 may correct the baud rate again.

In this case, if the control LSI 3311 determines in step S2660 that the LSI temperature is not within the second allowable range (NO), it executes the same processing as in step S2657 to calculate the corrected baud rate value, and If the baud rate setting value is different from the corrected baud rate setting value that has already been set, the same processing as in step S2658 is executed, and the projector reception abnormality processing ends.

In step S2654 of the above-described surface temperature diagnosis process, when the control LSI 3311 calculates the average value Av of the difference in CountBuf, the average value Av is calculated by simple moving average. You may calculate the average value Av by other moving averages, such as.

Further, in steps S2656 and S2657 of the projector reception abnormality processing described above, if the control LSI 3311 determines that the error of the average value of the difference of the CountBuf with respect to the reference value is outside the allowable range, it calculates the correction baud rate set value. described as what to do.

On the other hand, the control LSI 3311 may calculate a corrected baud rate setting value when it determines that the state in which the error of the difference of the CountBuf with respect to the reference value is outside the allowable range continues for a predetermined number of times.

Further, when the control LSI 3311 determines that the number of times that the error of the CountBuf difference with respect to the reference value is outside the allowable range exceeds the upper limit number of times (for example, 3 times) among the specific number of times (for example, 5 times), , the correction baud rate setting value may be calculated.

Further, the control LSI 3311 may calculate a corrected baud rate set value when determining that the error of the difference of the CountBuf with respect to the reference value is out of the allowable range even once.

It is possible to assume that the LSI temperature is within the second allowable range and the system CLK error value is less than the lower limit value or more than the upper limit value. The deviation is thought to be caused by an abnormality in the frequency of the system CLK output from the oscillation circuit due to other factors, and there is no guarantee that the reception error will be resolved even if the baud rate is corrected as a countermeasure. No baud rate correction is performed.

As described above, in the game machine 3001 according to the present modification, the clock generated during the reception time interval of the VSYNC signal in the state where the temperature of the control LSI 3311 is outside the first allowable temperature range in the projector device 3300 If the number is out of the allowable range (the error value is above the lower limit and below the upper limit), the baud rate with the sub control board 3200 is changed according to the number of clocks generated during the reception time interval of the VSYNC signal. By correcting, reception errors occurring in the projector device 3300 and the sub control board 3200 are suppressed, so it is possible to prevent the communication response between the projector device 3300 and the sub control board 3200 from deteriorating.

Further, in the gaming machine 3001 according to this modification, after correcting the communication speed in the projector device 3300, if the temperature of the control LSI 3311 falls within the second allowable range, the baud rate is corrected to the baud rate before correction. Therefore, by correcting the baud rate, further occurrence of reception errors can be suppressed.

Although the case where the embodiment of the present invention is applied to a pachislot machine has been described above, the present invention can also be applied to other gaming machines (for example, pachinko machines, slot machines, etc.).

A game is started by operating a bet button to insert a bet button, and if medals are to be paid out when the game is over, the hopper mechanism HP is driven to pay out the medals from the medal payout port 3021, or , credits have been described, but the present invention is not limited to this. Also, the forms of the insertion operation and the payout in the gaming machine 4001 shown in Modification 3 are also examples, and the present invention is not limited to this.

For example, for all forms in which a player inserts game media necessary for a game, a game is played based on it, and a privilege is awarded (for example, medals are paid out) based on the result of the game, The present invention can be applied. In other words, not only is the game medium inserted (played) and paid out by the player's physical actions, but also the main control circuit (main control board MS) itself receives the game medium held by the player. It may be managed electromagnetically and may be played without medals. In this case, it is the game medium management device mounted (connected) to the main control circuit (main control board MS) that manages the game medium, which electromagnetically manages the game medium held by the player. good too.

In this case, the game medium management device has ROM and RWM (or RAM), is provided in the game machine, and is capable of two-way communication with an external game medium handling device (not shown) via a predetermined interface. is connected to the game medium lending operation (that is, the action of providing the necessary game medium when the player performs the operation of inserting the game medium) or winning a prize related to the payout of the game medium (the relevant game media payout operation (that is, the operation of acquiring the game media necessary for paying out the game media to the player) in the case where the combination is established), or the game media used for the game are electromagnetically generated. It is sufficient that the operation of recording can be performed in real time. The game medium management device not only manages the actual number of game media, but also displays the number of owned game media (not shown) for displaying the number of game media owned, for example, based on the management result of the number of game media. may be provided on the front surface of the pachislot machine (gaming machine 3001) to manage the number of game media displayed on this display device for the number of owned game media. In other words, the game media management device may record and display the total number of game media that a player can use for games by an electromagnetic method.

In this case, the game medium management device may have a performance (function) that allows the player to freely transmit a signal indicating the number of recorded game media to an external game medium handling device. desirable. In addition, it is desirable that the game medium management device has a performance that does not allow the number of recorded game mediums to be reduced except when directly operated by the player. Also, if an external connection terminal board (not shown) is provided between the game medium management device and the external game medium handling device, the game medium management device can It is desirable for a player to have the ability to not send a signal indicating the number of game media recorded.

In addition to the above, the game machine is provided with lending operation means, return (settlement) operation means, and an external connection terminal board that can be operated by the player. Slots for recording media (e.g. IC cards), non-contact communication antennas for depositing electronic money, etc., from mobile terminals, various operation means such as lending operation means, return operation means, etc., and external connections on the game media handling device side A terminal board may be provided (neither shown).

As a game flow at that time, for example, the player deposits valuable value into the game medium handling device by any of the above methods, and a predetermined number of valuable values is subtracted, and the game media corresponding to the subtracted valuable value are increased from the game media handling device to the game media management device. Then, the player plays the game, and repeats the above operation when the game medium is required. After that, as a result of the game, a predetermined number of game media are obtained, and when the game is finished, the game media management device sends the game media handling device the number of game media by operating one of the return operation means. , and the game medium handling device ejects the recording medium recording the number of game media. Also, when the game medium management device transmits the number of game media, it clears the number of game media stored in itself. The player takes the ejected recording medium to a prize counter or the like to exchange for prizes, or moves the game machine to play a game on another game machine based on the recorded game medium.

In the above example, the total number of game media was transmitted from the game media management device to the game media handling device. The game media possessed by the player may be divided and processed. Also, in the above example, the game medium handling device ejects the recording medium, but cash or cash equivalents may be ejected, or may be stored in a portable terminal or the like. Further, the game medium handling device may be configured so that the member recording medium of the game parlor can be inserted, the game medium is stored in the member recording medium, and the stored game medium can be used to play again at a later date. .

Also, in the game machine or the game medium handling device, by operating a predetermined operation means (not shown), it is possible to perform a lock operation to lock the game medium or valuable value data communication to the game medium handling device or the game medium management device. may be In this case, information that only the player can know, such as a one-time password, may be set, or the player may be stored by imaging means provided in the game machine or game medium handling device.

As described above, the game medium management device may allow the game to be played only without medals, or the game medium may be inserted (played) by a physical action of the player, and the game medium may be released. The game may be played in both a payout mode and a mode in which the game can be played without medals. In the latter case, the game media management device may adopt a method of directly controlling the selector 50 and the hopper mechanism HP described above. It is also possible to employ a system that can electromagnetically record and display the total number of game media that can be used by the player based on the transmission of the control result.
