  Hereinafter, an embodiment in which the present invention is applied to a projection system including a projector device and a personal computer will be described with reference to the drawings.

  FIG. 1 illustrates a state in which a projector device 10 and a notebook type personal computer PC are connected by a USB cable CA1 and an RGB cable CA2.

  In this case, a projection condition setting process, which will be described later, is executed based on the projection condition setting software installed in the personal computer PC in advance, and control information is transmitted via the USB cable CA1 to project the projection condition of the projector apparatus 10. Is properly arranged, for example, presentation software is executed, image data of the presentation is transmitted to the projector apparatus 10 via the RGB cable CA2, and is projected and displayed by the projector apparatus 10.

  It should be noted that the hardware configuration of the personal computer PC is basically the same as that of a general computer, and the description and illustration thereof are omitted.

  FIG. 2 shows an external configuration of the projector device 10 as a projection control target. FIG. 2 (A) is mainly arranged on the front and top surfaces of the housing, and FIG. 2 (B) is arranged on the back and bottom surfaces of the housing. The configuration is shown.

  As shown in FIG. 2A, a projection lens 12, a distance measuring sensor 13, and an Ir receiver 14 are disposed on the front surface of a rectangular parallelepiped main body casing 11.

  The projection lens 12 is for projecting a light image formed by a spatial light modulation element such as a micromirror element, which will be described later, onto an object such as a screen, and here, a focus position and a zoom position (projection angle of view). Is arbitrarily variable.

  The distance measuring sensor 13 is arranged in a direction orthogonal to each other so that one of the two pairs of phase difference sensors is in the horizontal direction and the other is in the vertical direction. The distance to the light / dark pattern is measured along a one-dimensional detection line.

  The Ir receiver 14 receives an infrared light (Ir) signal on which a key operation signal from a remote controller of the projector device 10 (not shown) is superimposed.

  A speaker 18 is disposed on the upper surface of the main body casing 11. This speaker 18 emits a sound of the input audio signal and a beep sound during operation.

Further, as shown in FIG. 2B, an input / output connector portion 19, an Ir receiving portion 20, and an AC adapter connecting portion 21 are disposed on the back surface of the main body casing 11.
The input / output connector unit 19 includes a USB terminal for connection to an external device such as a personal computer, a mini D-SUB terminal for video input using RGB signals, an S terminal, an RCA terminal, and a stereo mini for audio input. It consists of terminals.

Similar to the Ir receiver 14, the Ir receiver 20 receives an infrared light (Ir) signal on which a key operation signal from a remote controller (not shown) is superimposed.
The AC adapter connection unit 21 connects a cable from an AC adapter (not shown) serving as a power source.

  Further, adjustment legs 22 a to 22 d capable of height adjustment are attached to the four corners of the lower surface of the main casing 11. The lengths of these adjusting legs 22a, 22b, 22c, and 22d are adjusted by key operations on the keyboard unit 16.

  In the state of FIG. 2B, the pair of adjustment legs 22a and 22b positioned on the front side are adjusted slightly longer, and the pair of adjustment legs 22c and 22d positioned on the rear side are adjusted to the shortest state. Has been.

  Therefore, when the projector device 10 in this state is installed in a horizontal place, if the projection optical axis of the projection lens 12 is perpendicular to the mounting surface of the projection lens 12, the actual projection lens 12 This projection optical axis has a slight elevation angle, and is emitted toward a screen (not shown) to be projected, slightly upward.

  Therefore, if the screen to be projected is stretched in the vertical direction, the distance from the projection lens 12 increases as it approaches the upper end of the screen. Therefore, when automatic keystone correction is not performed, a rectangular image is displayed. When projected, a trapezoidal image in which the upper base is longer than the lower base is projected and displayed on the screen.

  Next, the functional configuration of the electronic circuit of the projector apparatus 10 will be described with reference to FIG. In the figure, image signals of various standards input from the input / output connector unit 19 are unified into image signals of a predetermined format by the image conversion unit 32 via the input / output interface (I / F) 31 and the system bus SB. Later, it is sent to the display encoder 33.

  The display encoder 33 develops and stores the transmitted image signal in the video RAM 34, generates a video signal from the stored contents of the video RAM 34, and outputs the video signal to the display driving unit 35.

  The display drive unit 35 drives and displays the spatial light modulation element (SOM) 36 with higher speed time division drive according to a frame rate, for example, 30 [frame / second] as appropriate in response to the transmitted image signal. Therefore, for this spatial light modulation element 36, for example, high-intensity white light emitted from a light source lamp 38 such as an ultrahigh pressure mercury lamp disposed in a reflector 37 is appropriately colored to a primary color via a color wheel 39. By irradiating through the mirror 40, a light image is formed by the reflected light, and is projected and displayed on a screen (not shown) through the projection lens 12.

However, the projection lens 12 is driven by the lens motor (M) 41 to move the zoom position and the focus position as appropriate.
The control unit 42 controls all the operations of the circuits. The control unit 42 includes a CPU, a non-volatile memory that stores an operation program executed in the projector device 10, a work memory, and an RTC (Real Time Clock) that keeps counting the current time regardless of power on / off. ) And the like, and in response to a control command input from an external snow blower via the input / output connector unit 19 or a key operation signal received from the remote controller received by the Ir receivers 14 and 20, Is executed.

  The control unit 42 is also connected to a leg driving unit 45, a distance measurement processing unit 46, and an audio processing unit 47 via the system bus SB.

  Under the control of the control unit 42, the leg drive unit 45 individually drives each motor (not shown) connected to the adjustment leg portions 22a to 22d attached to the lower surface of the main body casing 11, The posture of the main casing 11 is controlled by adjusting the leg lengths of the adjusting leg portions 22a to 22d.

  The distance measurement processing unit 46 drives the distance sensor 13 to measure the vertical and horizontal distances to the projection target.

The sound processing unit 47 includes a sound source circuit such as a PCM sound source, converts the sound data given at the time of the projection display operation into analog, and drives the speaker 18 to emit loud sound.
Next, the operation of the above embodiment will be described.
FIG. 4 shows driver software bundled with the projector device 10 as a product, and the projector device 10 is connected to the personal computer PC via the USB cable CA1 and the RGB cable CA2 by being installed in the personal computer PC in advance. The processing contents of the program for setting projection conditions of the projector apparatus 10 executed by the personal computer PC in the state of the above are shown.

When the application software is started up at the beginning (step A01), a key operation window KW as shown in FIG. 5 is displayed on the display screen of the personal computer PC.
The key operation window KW shown in FIG. 5 includes, for example, an AF (Automatic Focus) key Ka, an AKSC (Automatic Key-Stone Correction) key Kb, a zoom key Kc, a height key Kd, and left and right keys. Ke, signal selection key Kf, setting display key Kg, setting input key Kh, setting storage key Ki, and automatic setting key Kj.

  The AF key Ka is used when the distance sensor 13 of the projector device 10 and the distance measurement processing unit 46 are driven to measure the distance from the projector device 10 to the screen to be projected and set the focus position. It is assumed that the pointing device P is clicked with a pointing device such as a mouse, and the same instruction can be performed by operating the shortcut key “F” as shown in the figure.

  The AKSC key Kb corrects the projection when the projection optical axis of the projection lens 12 is not perpendicular to the screen surface to be projected, and a projected image that is originally rectangular is projected as a trapezoid. It is instructed by a click operation, and the same instruction can be performed by operating the shortcut key “K” as shown in the figure.

  The zoom key Kc is displayed as a seesaw type key switch, and is designated by a click operation to widen the projection angle of view (zoom up (△)) or narrow (angle down (▽)). It is assumed that the same instruction can be given by operating the keys “T” and “W”.

  The height key Kd is displayed as a seesaw type key switch, and the projected image is controlled by controlling the relative leg length of the front side (22a, 22b) and the rear side (22c, 22d) of the adjustment leg portions 22a to 22d. Whether to increase (△) or lower (か) is instructed by a click operation, and the same instruction can be performed by operating the shortcut keys “U” and “D” as illustrated.

  The left / right key Ke is displayed as a seesaw-type key switch, and controls the relative leg lengths of the right side (22b, 22c) and the left side (22a, 22d) of the adjustment leg portions 22a to 22d to control the right side ( It is instructed by a click operation to increase either [Delta] or the left side ([Delta]), and the same instruction can be performed by operating the shortcut keys "R" and "L" as shown.

  The signal selection key Kf is an instruction for sequentially selecting input video and audio signals by a click operation, and the same instruction can be performed by operating the shortcut key “S” as shown in the figure.

  The setting display key Kg is used for instructing the display screen of the personal computer PC by clicking the display of various data constituting the projection condition, and the same instruction can be performed by operating the shortcut key “V” as shown in the figure. Shall.

  The setting input key Kh is clicked when a place name corresponding to the projection condition is input and displayed on the display screen of the personal computer PC. The same instruction can be given by operating the shortcut key “I” as shown in the figure. It shall be possible.

  The setting storage key Ki is a click operation for storing various data constituting the projection condition and the corresponding place name inputted as a projection condition file. As shown in the figure, the shortcut key “M” is operated. However, the same instruction can be given.

  The automatic setting key Kj is clicked when the projection conditions of the projector apparatus 10 are automatically set all at once according to the already stored projection condition file. The same applies to the operation of the shortcut key “A” as shown in the figure. Can be instructed.

  In the state where the key operation window KW is displayed on the screen of the PC as described above, a corresponding operation is executed depending on which key is instructed thereafter.

  Specifically, it is first determined whether or not a new installation operation is to be performed without using the already stored projection conditions (step A02).

  Here, when a new installation work is performed, the leg drive unit 45 is operated to increase or decrease the leg lengths before and after the adjusting leg portions 22a to 22d by the operation of the height key Kd of the key operation window KW. The height position of the projection image (white image on which nothing is displayed) projected on the screen is adjusted (step A03).

  Next, if necessary, the left and right leg lengths of the adjusting leg portions 22a to 22d are adjusted by the leg drive unit 45 by operating the left and right keys Ke of the key operation window KW, and projected onto the projection target screen. The left / right inclination of the projected image (white image on which nothing is displayed) is adjusted (step A04).

  Thereafter, the zoom lens K 41 in the key operation window KW is operated by the lens motor 41 to move the zoom lens in the projection lens 12, and the projection angle of view so that the projection image projected on the projection target screen has an appropriate size. (Zoom magnification) is adjusted (step A05).

  Thereafter, by continuously operating the AF key Ka and the AKSC key Kb of the key operation window KW, automatic focusing and keystone correction are automatically executed by the control unit 42 of the projector device 10 (steps A06 and A07). With the above, one set of operations related to setting the projection conditions is completed.

  Here, whether or not to store the projection condition in a file and store it in the personal computer PC is selected and set (step A08). When storing, the setting input key Kh of the key operation window KW is operated.

  If the setting input key Kh is operated and it is determined in step A08 that the projection condition is stored, then the state shifts to a state in which a place name corresponding to the data of the projection condition is input at the time (step A09).

  FIG. 6 exemplifies an installation location input window W1 displayed on the screen of the personal computer PC in response to the operation of the setting input key Kh. Here, as information on “installation position”, the projection distance, While the horizontal angle, vertical angle, and zoom magnification are displayed, the location name “Headquarters Meeting Room A” and other information “Business Meeting” are entered and set together with date and time information as “Installation Location”. Indicates the state. Here, the date and time information is automatically input and set as described above.

  In this way, while accepting the place name and other inputs, at the same time, the input setting is completed and the system waits for an instruction to store the input contents. This is because the setting storage key Ki of the key operation window KW is set. Judgment is made based on whether or not it has been operated (step A10).

  If it is determined in step A10 that the setting storage key Ki has been operated and the storage of projection condition data has been instructed, as shown in FIG. In addition, information and date / time information are stored in a predetermined file folder in, for example, the c drive (hard disk device) of the personal computer PC (step A11), and the processing relating to the series of projection condition setting is completed.

  Thereafter, this program is terminated as necessary (step A12), and the process proceeds to an operation of selecting a projection file such as a presentation program and executing projection.

  If it is determined in step A08 that the setting input key Kh of the key operation window KW is not operated and the projection conditions are not filed and stored in the personal computer PC, the processing from step A09 onward is performed. The process of FIG. 4 is terminated without executing it.

  When the projector apparatus 10 is installed again at the installation location shown in FIG. 6 at a later date, the processing shown in FIG. 4 is started again, the program is started up, the key operation window KW is displayed, and the setting display key is displayed. Operate Kg.

  If it is determined in step A02 that a projection condition file has been stored in the past by operating the setting display key 17g, the stored projection condition file name is set to the date and place name, and other names. After displaying the list together with the information (step A13), it waits for any one to be selected (step A14).

  FIG. 7 exemplifies a list display window W2 of locations where projection conditions have been stored in the past using the projector device 10 displayed on the screen of the personal computer PC by operating the setting display key Kg. .

  Here, when the installation location is selected by the keyboard operation of the personal computer PC or the direct operation with the pointer P by the pointing device, this is determined in step A14, and the projection selected from the file folder in the personal computer PC is selected. A set of condition file data is read and the contents are displayed on the screen of the personal computer PC (step A15).

  FIG. 8 shows an example of the projection condition window W3 for the place name “Head Office Meeting Room A” displayed on the screen of the personal computer PC at this time. As shown in the figure, on the left and center of the screen, detailed explanations regarding “installation location” and “installation position” are displayed, while on the right side of the screen, the projector device 10 based on the “installation position” and the projection target are displayed. The relationship with the screen is visually expressed and prompts the user to confirm the contents.

  In this state, it is further determined whether or not to confirm the contents of the projection condition by operating the automatic setting key Kj of the key operation window KW or operating the “Esc” key of the keyboard (step A16).

  Accordingly, when the automatic setting key Kj is operated from the state of the display screen shown in FIG. 8, this is determined in step A16, and the projection condition is determined via the USB cable CA1 based on the confirmed projection condition. Is transferred to the projector apparatus 10, and each leg, specifically, each leg length of the adjustment legs 22 a to 22 d by the leg driving unit 45 is adjusted by the lens motor 41 with the zoom angle and the in-focus position on the projection lens 12. However, the rectangular range of the image formed by the spatial light modulation element 36 is set by the display driving unit 35 (step A17), and the program is automatically terminated assuming that the automatic setting of the projection conditions has been completed. (Step A12), the process of FIG.

  When the “Esc” key of the keyboard is operated from the state where the contents of the projection condition selected in step A15 are displayed on the screen, this is determined in step A16, and the list display screen in step A13 is displayed. Shall return.

  In this way, when the projector apparatus 10 connected to the personal computer PC is installed and a projection operation is performed, if the projection condition is acquired and stored on the personal computer PC side as needed, it is the second time at the same place. The projection conditions for subsequent installations can be automated in a batch by resetting, and installation work can be greatly simplified.

  In this case, as projection conditions that can be stored on the personal computer PC side, projection conditions corresponding not only to one place but also to a plurality of installation positions are stored together with the identification information, and the corresponding projection conditions are selected by selecting and specifying the identification information. Since the resetting is performed, even when the personal computer PC and the projector apparatus 10 are connected and reused in a plurality of places, the projection conditions corresponding to the respective installation positions can be automatically automated by resetting. it can.

  In that case, basically, a personal computer PC having a Japanese display system with a large display screen and a keyboard is used, and a user can arbitrarily input an installation location name as an identification name. Even when the projector device 10 connected to the personal computer PC is used, the necessary projection conditions can be selected immediately, and the usability can be improved without causing unnecessary confusion.

  In the above embodiment, as shown in FIG. 7, the date, location, and other information are displayed as a list display screen of locations where the projection conditions have been stored in the past using the projector device 10. However, the identification information of the image data file actually projected after setting the projection conditions, for example, the location stored in the personal computer PC, the image file name, and the extension are stored together, and the contents are stored. You may make it confirm.

  FIG. 9 illustrates another list display window W4 that is displayed on the screen of the personal computer PC by the operation of the setting display key Kg and where the projection conditions are stored in the past using the projector device 10. is there.

  In this case, for example, the file name “catalog” stored in the file folder “My Documents” in the “c” drive (of the personal computer PC) at the location “head office meeting room A” on the date “May 20, 2003”. Since the JPEG (still image) data is projected, the contents of the projected image can be understood at a glance, so it becomes possible to grasp past projection contents more easily and select the necessary ones. .

  In the above embodiment, the personal computer PC is connected to the projector apparatus 10 using the USB cable CA1 to transmit and receive various control information. However, image data is transmitted from the personal computer PC to the projector apparatus 10. The connection is not limited to the wired connection including the connection of the RGB cable CA2 to be output to the wireless LAN, and a wireless LAN technology generally indicated by Bluetooth or IEEE802.11a (or 802.11b, 802.11g) may be used.

  In the above embodiment, the projector device 10 displays the leg lengths of the adjustment legs 22 a to 22 d, the in-focus position and zoom angle (projection angle of view) of the projection lens 12, and the spatial light modulator 36. However, the present invention is not intended only for projector devices that can adjust all of them, and at least two factors among them are considered. If it can be automated in a lump, it is considered to be sufficiently useful in that it can simplify the work at the time of installation as compared with the case of performing key operations instructing automation of individual factors.

  Further, in the above-described embodiment, the projection optical axis has been described as storing the “deviation angle” formed by the vertical direction with respect to the screen surface to be projected and the projection optical axis as information necessary for automatic trapezoidal correction. , Instead of performing the calculation for automatic keystone correction every time the "shift angle" is memorized and reset, a correction value that can be directly used for automatic keystone correction, that is, a rectangular image is obtained. It may be possible to store a numerical value indicating whether the image is displayed in the correct rectangle as a result if the display is driven by the spatial light modulator 36 after being distorted in what direction and in what ratio.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  Further, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements.
