Description

  The present invention relates to a slot machine for displaying a symbol on a display device and related technology.

  Patent Document 1 discloses a coin game device. In this coin game apparatus, three drum images are displayed on the television monitor. When the player inserts coins and presses the enter button, the drum image rotates. When the player operates the handle to select a drum image and presses the enter button, the selected drum image is stopped. In this way, when three drum images are stopped and three identical symbols are arranged, coins corresponding to the number of inserted coins are paid out.

JP 2005-21654

  As described above, conventionally, the drum image is rotated by inserting coins, and the drum image is stopped by pressing the enter button. In a typical slot machine, a coin is inserted, a lever is pulled, the drum is rotated, and a button is pressed to stop the drum.

  Accordingly, an object of the present invention is to provide a slot machine that can be controlled in a non-contact manner and a related technique.

  According to an aspect of the present invention, the slot machine is configured to detect the movement of the subject based on a subject worn on the palm of the player, an imaging unit that captures the subject, and an image of the subject captured by the imaging unit. A cursor that is detected and linked to the detected movement of the subject, a first operated object and a second operated object that are operated based on the cursor, and the first operated object and the second And a processor that displays on the display device a pseudo-rotation image whose movement is controlled based on the operated object of the object, the processor immediately after the cursor overlaps the first operated object. If an image is not obtained, the stopped pseudo-rotation image is changed, and the cursor overlaps the second operated object. If the image of the subject is not obtained immediately after, the pseudo-rotation image being changed is stopped, and a pseudo reward is given according to the pattern included in the stopped pseudo-rotation image .

  According to this configuration, the real drum, the real lever, and the real button are respectively referred to as a pseudo rotation image, a first operated object, and a second operated object (hereinafter, the first and second operated objects are collectively referred to as “ It is also provided as an image as a “target”.) These operations are performed by opening or closing the palm to direct or hide the subject toward the imaging means. In addition, the actual buttons and the mechanism for driving them are not required, and it is difficult to break down, and a slot machine can be configured with space saving, simple and low cost. In addition, a slot machine that can be operated without contact can be provided.

  In addition, the player can operate or change the target by moving the cursor with the palm open, overlaying the target, and clenching the hand to hide the subject. Therefore, the player can give an input by an operation as if holding the target. As a result, it becomes a hand exercise for the player, and can also be used for rehabilitation.

  Furthermore, since the slot machine can be driven simply by opening or closing the palm, even an infant, an elderly person, a physically handicapped person or the like can easily enjoy the slot machine.

  In the slot machine, the pseudo-rotation image includes a plurality of independent pseudo-rotation images that change independently, and the second operated object includes a plurality of operated parts corresponding to the plurality of independent pseudo-rotation images. The processor gives a change to all the independent pseudo-rotated images that have been stopped when the image of the subject is not obtained immediately after the cursor has overlapped the first operated object, If an image of the subject cannot be obtained immediately after the cursor overlaps the operated portion, the changing independent pseudo-rotating image corresponding to the operated portion is stopped, and all the independent independent changes are made. When the pseudo-rotation image is stopped, a pseudo reward is given according to the order and combination of symbols included in all the independent pseudo-rotation images.

  In the slot machine, the pseudo reward is a pseudo coin.

  The slot machine further includes light emitting means for irradiating the subject with light, and the subject includes a retroreflective member.

  According to this configuration, since the light irradiated by the retroreflective member is retroreflected, the image of the retroreflective member is clearly reflected in the captured image, and the retroreflective member can be easily detected.

  In this slot machine, the light emitting means is repeatedly turned on and off, and the processor obtains a captured image obtained by the imaging means when the light emitting means is turned on and obtained by the imaging means when the light emitting means is turned off. The movement of the subject is detected based on the difference image between the captured image and the captured image.

  According to this configuration, since a difference between lighting and extinguishing is obtained, noise due to light other than the reflected light from the retroreflective member can be removed as much as possible, and the retroreflective member can be detected with high accuracy.

  In this slot machine, the light emitted from the light emitting means is infrared light, and the imaging means responds only to infrared light.

  According to this configuration, the light emitting means emits infrared light, and the imaging means responds only to the infrared light. In this way, the imaging means does not respond to light other than infrared light, and it is possible to remove noise light sources such as moving light sources and blinking light sources (such as fluorescent lamps) that contain light other than infrared light.

  In the slot machine, the subject includes a first object portion that is attached to the palm of the right hand of the player and a second object portion that is attached to the palm of the left hand, and the cursor moves to the movement of the first object portion. A first response image that is interlocked and a second response image that is interlocked with the movement of the second object portion are included.

  According to this configuration, since the player uses both hands, not only the dominant hand but also the other hand moves equally. As a result, exercise or rehabilitation of both hands can be performed in a well-balanced manner.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and the description thereof is incorporated.

  FIG. 1 is a block diagram showing an overall configuration of a slot machine according to an embodiment of the present invention. As shown in FIG. 1, the slot machine includes an information processing device 1, input devices 3L and 3R, and a television monitor 5. Here, when it is not necessary to distinguish between the input devices 3L and 3R, they are referred to as the input device 3.

  FIG. 2 is a perspective view of the input device 3 of FIG. As shown in FIG. 2, the input device 3 is formed by passing a belt 19 on the bottom surface side of the transparent body 17 and fixing the belt 19 inside the transparent body 17. The retroreflective sheet 15 is attached over the entire inner surface of the transparent body 17 (excluding the bottom surface side).

  Here, when it is necessary to distinguish between the input devices 3L and 3R, the transparent body 17 and the retroreflective sheet 15 of the input device 3L are referred to as the transparent body 17L and the retroreflective sheet 15L, respectively, and the input device 3R is transparent. The body 17 and the retroreflective sheet 15 are referred to as a transparent body 17R and a retroreflective sheet 15R, respectively.

  Returning to FIG. 1, the information processing apparatus 1 is connected to the television monitor 5 by the AV cable 7. Further, although not shown, the information processing apparatus 1 is supplied with a power supply voltage by an AC adapter or a battery. A power switch (not shown) is provided on the back surface of the information processing apparatus 1.

  The information processing apparatus 1 is provided with an infrared filter 20 that transmits only infrared light on the front side thereof, and further, four infrared light emitting diodes 9 that generate infrared light are exposed so as to surround the infrared filter 20. is doing. An image sensor 54 described later is disposed on the back side of the infrared filter 20.

  The four infrared light emitting diodes 9 emit infrared light intermittently. The infrared light from the infrared light emitting diode 9 is reflected by the retroreflective sheet 15 attached to the input device 3 and input to the image sensor 54 provided on the back side of the infrared filter 20. In this way, the input device 3 is photographed by the image sensor 54.

  When infrared light is irradiated intermittently, photographing processing by the image sensor 54 is performed even when infrared light is not irradiated. Therefore, the information processing apparatus 1 obtains the difference between the image signal at the time of infrared light irradiation and the image signal at the time of non-irradiation, and based on the difference signal DI (difference image DI), the input device 3 (that is, retroreflection). The position of the sheet 15) is calculated.

  Thus, by obtaining the difference, noise due to light other than the reflected light from the retroreflective sheet 15 can be removed as much as possible, and the retroreflective sheet 15 can be detected with high accuracy.

  FIG. 3 is an explanatory diagram showing an example of a usage state of the input devices 3L and 3R in FIG. As shown in FIGS. 1 and 3, the player puts the input device 3 by passing the middle finger through the belt 19 in FIG. 2. In this case, the transparent body 17 and the retroreflective sheet 15 are placed on the palm side. As shown in FIG. 1, when the player opens his hand toward the information processing apparatus 1, that is, toward the image sensor 54, the transparent body 17, that is, the retroreflective sheet 15 appears. Taken. On the other hand, when the transparent body 17 is clamped, the transparent body 17, that is, the retroreflective sheet 15 is hidden in the hand and is not photographed by the image sensor 54. Therefore, the player can control the input to the information processing apparatus 1 by causing the retroreflective sheet 15 to be photographed or not photographed by opening and closing the hand. In the present embodiment, a case where the retroreflective sheet 15 is photographed is referred to as an imaging state, and a state where the retroreflective sheet 15 is not photographed is referred to as a non-imaging state.

  FIG. 4 is a diagram showing an electrical configuration of the information processing apparatus 1 of FIG. As illustrated in FIG. 4, the information processing apparatus 1 includes a multimedia processor 50, an image sensor 54, an infrared light emitting diode 9, an external memory 52, and a bus 56. The external memory 52 includes a ROM, a RAM, and / or a flash memory that is necessary according to the system specifications.

  The multimedia processor 50 can access the external memory 52 through the bus 56. Therefore, the multimedia processor 50 can execute the program stored in the external memory 52 and can read and process the data stored in the external memory 52. The external memory 52 stores in advance an application program (see FIG. 8) for performing various processes such as screen control, position detection of the retroreflective sheets 15L and 15R, and input determination, image data, audio data, and the like.

  Although not shown, the multimedia processor includes a central processing unit (hereinafter referred to as “CPU”), a graphics processing unit (hereinafter referred to as “GPU”), and a sound processing unit (hereinafter referred to as “SPU”). ), A geometry engine (hereinafter referred to as “GE”), an external interface block, a main RAM, an A / D converter (hereinafter referred to as “ADC”), and the like.

  The CPU executes programs stored in the external memory 52 to perform various calculations and control of the entire system. As processing of the CPU related to graphics processing, a program stored in the external memory 52 is executed, and parameters for enlargement / reduction, rotation, and / or translation of each object, viewpoint coordinates (camera coordinates), and line-of-sight vector are calculated. Perform calculations. Here, a unit composed of one or a plurality of polygons or sprites and applied with the same transformation of enlargement / reduction, rotation, and translation is referred to as an “object”.

  The GPU generates a three-dimensional image composed of polygons and sprites in real time and converts it into an analog composite video signal. The SPU generates PCM (pulse code modulation) waveform data, amplitude data, and main volume data, and analog-multiplies them to generate an analog audio signal. The GE performs a geometric operation for displaying a three-dimensional image. Specifically, the GE performs operations such as matrix product, vector affine transformation, vector orthogonal transformation, perspective projection transformation, vertex brightness / polygon brightness calculation (vector inner product), and polygon back surface culling processing (vector outer product).

  The external interface block is an interface with peripheral devices (in this embodiment, the image sensor 54 and the infrared light emitting diode 9), and includes a 24-channel programmable digital input / output (I / O) port. The ADC is connected to four-channel analog input ports, and converts analog signals input from the analog input device (in this embodiment, the image sensor 54) into digital signals through these ADCs. The main RAM is used as a CPU work area, a variable storage area, a virtual storage mechanism management area, and the like.

  The input devices 3L and 3R are irradiated with the infrared light of the infrared light emitting diode 9, and the infrared light is reflected by the retroreflective sheets 15L and 15R. The reflected light from the retroreflective sheets 15L and 15R is photographed by the image sensor 54. Therefore, the image sensor 54 outputs image signals including the retroreflective sheets 15L and 15R. As described above, the multimedia processor 50 intermittently blinks the infrared light-emitting diode 9 for strobe photography, so that an image signal when the infrared light is extinguished is also output. These analog image signals from the image sensor 54 are converted into digital data by an ADC built in the multimedia processor 50.

  The multimedia processor 50 generates the difference signal DI (difference image DI) from the digital image signal input from the image sensor 54 via the ADC, and based on this, the input determination by the input devices 3L and 3R, The positions of the input devices 3L and 3R are detected, calculation, graphic processing, sound processing, etc. are executed, and a video signal and an audio signal are output. The video signal and the audio signal are given to the television monitor 5 through the AV cable 7, and accordingly, an image is displayed on the television monitor 5, and sound is output from a speaker (not shown).

  As will be described later, the multimedia processor 50 controls the movement of the cursors 70L and 70R according to the detected positions of the input devices 3L and 3R. That is, the multimedia processor 50 extracts the images of the retroreflective sheets 15L and 15R from the difference image DI, and calculates the coordinates of the respective points of interest on the difference image DI. Then, the multimedia processor 50 obtains the positions of the two points of interest on the screen of the television monitor 5 by converting the coordinates on the difference image DI of the two points of interest into screen coordinates. The multimedia processor 50 displays the cursors 70L and 70R at the positions on the screen of these two attention points (corresponding to the retroreflective sheets 15L and 15R). The screen coordinate system is a coordinate system used when displaying an image on the television monitor 5.

  FIG. 5 is a view showing an example of a play screen displayed on the television monitor 5 of FIG. Referring to FIG. 5, the play screen is a drum image (reel image) 36L, 36C and 36R, a lever image 32 for rotating the drum images 36L, 36C and 36R, and a drum image 36L for rotating. A stop button 34L, a stop button 34C for stopping the rotating drum image 36C, a stop button 34R for stopping the rotating drum image 36R, a remaining time display unit 38 for displaying the remaining time of play, and the player's A coin number display unit 40 for displaying the number of coins held is included. Further, the play screen includes cursors 30L and 30R that are linked to the input devices 3L and 3R, respectively.

  Here, when it is not necessary to distinguish the cursors 30L and 30R, they are represented as a cursor 30. When it is not necessary to distinguish the drum images 36L, 36C, and 36R, they are expressed as a drum image 36. When it is not necessary to distinguish the stop buttons 34L, 34C, and 34R, they are expressed as stop buttons 34. Further, the drum image 36 may be referred to as a drum 36, and the lever image 32 may be referred to as a lever 32.

  When the input device 3 is in the shooting state, the corresponding cursor 30 is in the shape of an open palm. When the input device 3 is changed from the photographing state to the non-photographing state, the corresponding cursor 30 has a shape (fist fist) in which the hand is clamped for a certain time (for example, 1 second). However, after the lapse of a certain time, the corresponding cursor 30 disappears until the input device 3 is again in the shooting state. Note that all or part of the color of the cursor 30 is translucent so that the back can be seen through. Further, a part of the cursor 30 may be completely transparent.

  The player moves the cursor 30 with the input device 3 in the shooting state (with the palm open), overlaps the lever image 32, and puts the input device 3 into the non-photographing state (the hand gripped state) to perform retroreflection. The sheet 15 is hidden. Thereby, the multimedia processor 50 assumes that the lever 32 has been operated, and rotates the drums 36L, 36C, and 36R. Such an operation is sometimes referred to as “holding the lever”. In the present embodiment, the rotation of the drums 36L, 36C, and 36R means that an image as the drum is rotating is displayed because a drum as an actual object does not exist.

  In addition, the player moves the cursor 30 with the input device 3 in the shooting state, overlaps the stop button 34, and puts the input device 3 into the non-shooting state to hide the retroreflective sheet 15. Accordingly, the multimedia processor 50 considers that the stop button 34 has been pressed, and stops the drum image 36 corresponding to the stop button 34. Such an operation may be referred to as “holding a stop button”.

  Here, the player can hold the lever 32 and the stop buttons 34L, 34C, and 34R using any of the cursors 30L and 30R. The player can hold the stop buttons 34L, 34C, and 34R in any order.

  When the player holds the lever 32 and rotates the drums 36L, 36C, and 36R, the number of coins on the coin number display unit 40 is decreased by one. When the player holds the stop buttons 34L, 34C and 34R and stops all the drums 36L, 36C and 36R, the order of the three symbols attached to the center of the three drums 36L, 36C and 36R and According to the combination, coins are paid out in a pseudo manner, and the number of coins on the coin number display unit 40 is increased by the amount paid out. Of course, coins may not be paid out depending on the order and combination of the three symbols. It should be noted that the pseudo coins are paid out in a video in which coin images are scattered.

  Next, detection processing and left / right determination processing of the retroreflective sheets 15L and 15R will be described with reference to the drawings.

  FIG. 6 is an explanatory diagram of detection processing of the retroreflective sheets 15L and 15R. FIG. 6 shows a difference image (32 × 32 pixels) based on difference image data generated from image data when infrared light is emitted and when the light is turned off. In the figure, a small square represents one pixel. The upper left corner is the origin of the XY coordinate axes.

  This image includes two regions 251 and 253 having large luminance values. Regions 251 and 253 are retroreflective sheets 15L and 15R. However, at this time, it cannot be determined which region corresponds to which retroreflective sheet.

  First, the multimedia processor 50 scans the difference image data from X = 0 to X = 31 with Y = 0 as the starting point, and then increments Y to make the difference from X = 0 to X = 31. Scan image data. Such processing is performed up to Y = 31, and the difference image data of 32 × 32 pixels is scanned to obtain the upper end position minY, lower end position maxY, left end position minX, and right end position maxX of the pixel data larger than the threshold ThL.

  Next, the multimedia processor 50 executes a scan in the positive direction of the X axis with the coordinates (minX, minY) as a starting point, and first calculates a distance LT to a pixel exceeding the threshold ThL. Further, the multimedia processor 50 executes a scan in the negative direction of the X axis starting from the coordinates (maxX, minY), and first calculates a distance RT to a pixel exceeding the threshold ThL. Further, the multimedia processor 50 performs a scan in the positive direction of the X axis with the coordinates (minX, maxY) as a starting point, and first calculates a distance LB to a pixel exceeding the threshold ThL. Further, the multimedia processor 50 executes a scan in the negative direction of the X axis starting from the coordinates (maxX, maxY), and first calculates a distance RB to a pixel exceeding the threshold ThL.

  The multimedia processor 50 sets the coordinates (maxX, minY) as the first extraction point when the distance LT> RT, and sets the coordinates (minX, minY) as the first extraction point when the distance LT ≦ RT. In addition, when the distance LB> RB, the multimedia processor 50 sets the coordinates (maxX, maxY) as the second extraction point, and when the distance LB ≦ RB, sets the coordinates (minX, maxY) as the second extraction point. .

  FIG. 7 is an explanatory diagram of the left / right determination process. In FIG. 7, the position TPL2 of the retroreflective sheet 15L of the previous time (one video frame before) and the position TPL1 of the previous time (two video frames before), the position TPR2 of the retroreflective sheet 15R of the previous time (one video frame before), and A position TPR1 two times before (one video frame before) is shown. Positions TPL1, TPL2, TPR1, and TPR2 are positions on the difference image based on the difference image data.

  The multimedia processor 50 calculates a velocity vector VL starting from the position TPL1 and ending at the position TPL2. Then, the end point of the velocity vector VL starting from the position TPL2 is set as the predicted position TPLp of the retroreflective sheet 15L. On the other hand, the multimedia processor 50 calculates a velocity vector VR starting from the position TPR1 and ending at the position TPR2. Then, the end point of the velocity vector VR starting from the position TPR2 is set as the predicted position TPRp of the retroreflective sheet 15R.

  The multimedia processor 50 includes a distance LD1 between the first extraction point TPN1 and the predicted position TPLp, a distance RD1 between the first extraction point TPN1 and the predicted position TPRp, a distance LD2 between the second extraction point TPN2 and the predicted position TPLp, and A distance RD2 between the second extraction point TPN2 and the predicted position TPRp is obtained.

  If the distance LD1> RD1, the multimedia processor 50 sets the first extraction point TPN1 as the current position of the retroreflective sheet 15R. If the distance LD1 ≦ RD1, the multimedia processor 50 sets the first extraction point TPN1 as the current position of the retroreflective sheet 15L. And Further, if the distance LD2> RD2, the multimedia processor 50 sets the second extraction point TPN2 as the current position of the retroreflective sheet 15R, and if the distance LD2 ≦ RD2, sets the second extraction point TPN2 as the current position of the retroreflective sheet 15L. The position of

  Thus, since the left and right are assigned to the first extraction point TPN1 and the second extraction point TPN2 based on the left and right predicted positions TPLp and TPRp, the left and right of the retroreflective sheet 15L and the retroreflective sheet 15R are switched. However (even if crossed), the multimedia processor 50 can accurately recognize each of the retroreflective sheets 15L and 15R on the difference image based on the difference image data.

  Next, the flow of processing by the multimedia processor 50 will be described using a flowchart.

  FIG. 8 is a flowchart showing an example of the overall processing flow by the multimedia processor 50 of FIG. With reference to FIG. 8, in step S1, the multimedia processor 50 performs initial setting of the system such as initialization of various variables. In step S <b> 3, the multimedia processor 50 executes processing according to the application program stored in the external memory 52. In step S5, the multimedia processor 50 stands by until an interrupt due to the video synchronization signal occurs. That is, the multimedia processor 50 returns to the same step S5 when the interrupt due to the video synchronization signal has not occurred, and proceeds to step S7 when the interrupt due to the video synchronization signal has occurred. For example, the interruption by the video synchronization signal occurs every 1/60 seconds. In synchronization with this interruption, in steps S7 and S9, the multimedia processor 50 updates the image displayed on the television monitor 5 and reproduces the sound. Then, the multimedia processor 50 returns to step S3.

  The application program that controls the processing in step S3 includes a plurality of programs. The plurality of programs include a program that executes processing shown in the flowchart below.

  FIG. 9 is a flowchart showing an example of the flow of the main part of the processing by the application program in step S3 of FIG. With reference to FIG. 9, in step S21, the multimedia processor 50 executes the photographing process of the retroreflective sheets 15L and 15R. In step S23, the multimedia processor 50 detects the images of the retroreflective sheets 15L and 15R based on the image obtained in step S21. In step S25, the multimedia processor 50 determines whether or not the player has performed an operation of grasping the target. Here, the target means an object to be gripped by the player, and in the above example, is the lever image 32 and the stop buttons 34L, 34C, and 34R. In step S26, the multimedia processor 50 determines the number of coins to be paid out based on the three symbols attached to the center of the three stopped drum images 36L, 36C and 36R. In step S27, the multimedia processor 50 executes control of video displayed on the television monitor 5 and other necessary calculations.

  FIG. 10 is a flowchart illustrating an example of the flow of the photographing process in step S21 of FIG. As shown in FIG. 10, in step S41, the multimedia processor 50 turns on the infrared light emitting diode 9. In step S43, the multimedia processor 50 acquires image data when the infrared light is turned on from the image sensor 54, and stores it in the main RAM.

  Here, in this embodiment, a CMOS image sensor of 32 pixels × 32 pixels is used as an example of the image sensor 54. Therefore, pixel data of 32 pixels × 32 pixels is output from the image sensor 54 as image data. This pixel data is converted into digital data by an A / D converter and stored as elements of a two-dimensional array P1 [X] [Y] on the main RAM.

  In step S45, the multimedia processor 50 turns off the infrared light emitting diode 9. In step S47, the multimedia processor 50 acquires image data (32 pixel × 32 pixel pixel data) when the infrared light is extinguished from the image sensor 54, and stores it in the main RAM. In this case, the pixel data is stored as an element of a two-dimensional array P2 [X] [Y] on the main RAM.

  The flash photography is performed as described above. Here, in the two-dimensional coordinate system representing the position of each pixel constituting the image by the image sensor 54, the horizontal direction is the X axis and the vertical direction is the Y axis. The origin O is the upper left corner of the image. In this embodiment, since the image sensor 54 of 32 pixels × 32 pixels is used, X = 0 to 31 and Y = 0 to 31. This also applies to the difference image DI. The pixel data is a luminance value.

  FIG. 11 is a flowchart showing an example of the flow of the sheet detection process in step S23 of FIG. As shown in FIG. 11, in step S61, the multimedia processor 50 determines pixel data P1 [X] [Y] when emitting infrared light and pixel data P2 [X] [Y] when turning off infrared light. And is substituted into the array Dif [X] [Y]. In step S63, the multimedia processor 50 proceeds to step S65 when the difference of 32 × 32 pixels is calculated, and proceeds to step S61 otherwise. As described above, the multimedia processor 50 repeats the process of step S61 to generate difference image data between the image data when the infrared light is emitted and the image data when the infrared light is turned off. Thus, by obtaining the difference image data (difference image), noise due to light other than the reflected light from the retroreflective sheets 15L and 15R can be removed as much as possible, and the retroreflective sheets 15L and 15R can be detected with high accuracy.

  In step S65, the multimedia processor 50 executes the left / right upper / lower end (minX, maxX, minY, maxY) detection processing described in FIG.

  FIG. 12 is a flowchart illustrating an example of the left / right upper / lower end detection process in step S65 of FIG. As shown in FIG. 12, in step S91, the multimedia processor 50 substitutes “0” for “X”, “Y”, “maxX”, “maxY”, “k”, and “SN”. Also, the multimedia processor 50 substitutes “31” for “minX” and “minY”.

  In step S93, the multimedia processor 50 compares the elements of the array Dif [X] [Y] with a predetermined threshold ThL. In step S95, the multimedia processor 50 proceeds to step S97 if the element of the array Dif [X] [Y] is greater than the predetermined threshold ThL, and proceeds to step S121 if it is less than or equal to the predetermined threshold ThL.

  The processes in steps S93 and S95 are processes for detecting whether or not the retroreflective sheets 15L and 15R are photographed. When the retroreflective sheets 15L and 15R are photographed, the luminance values of pixels corresponding to the retroreflective sheets 15L and 15R increase on the difference image. For this reason, the brightness value is distinguished by the threshold value ThL, and a pixel having a brightness value larger than the threshold value ThL is recognized as part of the photographed retroreflective sheets 15L and 15R.

  In step S97, the multimedia processor 50 increments the count value k by one. In step S99, the multimedia processor 50 determines whether or not the count value k is “1”. If k = 1, the process proceeds to step S101. Otherwise, the process proceeds to step S103.

  In step S101, the multimedia processor 50 substitutes the current Y coordinate for the minimum Y coordinate minY. In other words, the scan repeats the process of starting from (X, Y) = (0, 0), performing X = 0 to 31, incrementing Y, and again performing X = 0 to 31. (Refer to Steps S121 to S129 described later) “Y” of the array Dif [X] [Y] having an element (that is, a pixel) that first exceeds the threshold ThL is the minimum Y coordinate minY.

  In step S103, the multimedia processor 50 compares the current maximum Y coordinate maxY with the current Y coordinate. In step S105, the multimedia processor 50 proceeds to step S107 when the current Y coordinate is larger than the current maximum Y coordinate maxY, and proceeds to step S109 otherwise. In step S107, the multimedia processor 50 substitutes the current Y coordinate for the maximum Y coordinate maxY.

  In step S109, the multimedia processor 50 compares the current minimum X coordinate minX with the current X coordinate. In step S111, the multimedia processor 50 proceeds to step S113 if the current X coordinate is smaller than the current minimum X coordinate minX, and proceeds to step S115 otherwise. In step S113, the multimedia processor 50 substitutes the current X coordinate for the minimum X coordinate minX.

  In step S115, the multimedia processor 50 compares the current maximum X coordinate maxX with the current X coordinate. In step S117, the multimedia processor 50 proceeds to step S119 if the current X coordinate is larger than the current maximum X coordinate maxX, and proceeds to step S121 otherwise. In step S119, the multimedia processor 50 substitutes the current X coordinate for the maximum X coordinate maxX.

  In step S121, the multimedia processor 50 increments “X” by one. In step S123, the multimedia processor 50 proceeds to step S125 when X = 32 (that is, when the processing for one row of pixels of the difference image is completed), and proceeds to step S93 otherwise.

  In step S125, the multimedia processor 50 substitutes “0” for “X”. In step S127, the multimedia processor 50 increments “Y” by one. The processes in steps S125 and S127 are executed to advance the process for the next line because the process for one line of the difference image has been completed.

  In step S129, the multimedia processor 50 proceeds to step S131 when Y = 32 (that is, when processing of 32 × 32 pixels of the difference image is completed), and proceeds to step S93 otherwise.

  By repeating the above steps S93 to S129, when Y = 32, the minimum X coordinate minX, the maximum X coordinate maxX, the minimum Y coordinate minY, and the maximum Y coordinate maxY are all determined.

  In step S131, it is determined whether or not “maxX”, “maxY”, “minX”, and “minY” remain the initial values. If they are the initial values, the process proceeds to step S133, and otherwise returns. The fact that “maxX”, “maxY”, “minX”, and “minY” are all initial values means that all pixels of the difference image are equal to or less than the threshold ThL, and the retroreflective sheets 15L and 15R are not photographed. To do. Accordingly, in step S133, the multimedia processor 50 substitutes “01” (indicating that the number of photographed retroreflective sheets is zero) in the sheet number flag SN indicating the number of photographed retroreflective sheets. To do. In step S135, the multimedia processor 50 turns off the left open flag OL and the right open flag OR, and proceeds to step S77 in FIG. The left open flag OL and the right open flag OR are flags indicating that the retroreflective sheets 15L and 15R are photographed, respectively.

As shown in FIG. 13, the multimedia processor 50 substitutes “0” for “M” in step S151, and repeats the processing from step S153 to step S185. Here, as shown in step S153, Ytb = minY in the first loop, and Ytb = maxY in the second loop. In step S155, the multimedia processor 50 starts scanning with the coordinates (minX, Ytb) as a starting point.

  In step S157, the multimedia processor 50 substitutes “0” for the count value Cl. In step S159, the multimedia processor 50 compares the difference data Dif [X] [Y] with the threshold value ThL. If the difference data is larger than the threshold value, the multimedia processor 50 proceeds to step S165. Otherwise, the multimedia processor 50 proceeds to step S161. move on. In step S161, the multimedia processor 50 increments the count value Cl by one. In step S163, the multimedia processor 50 increments the coordinate X by one, and proceeds to step S159.

  The count value Cl when it is determined in step S159 that Dif [X] [Y]> ThL corresponds to the distance LT or LB in FIG. In step S155, when Ytb = minY, Cl = LT, and when Ytb = maxY, Cl = LB.

  In step S165, the multimedia processor 50 starts scanning using the coordinates (maxX, Ytb) as a starting point. In step S167, the multimedia processor 50 substitutes “0” for the count value Cr. In step S169, the multimedia processor 50 compares the difference data Dif [X] [Y] with the threshold value ThL. If the difference data is larger than the threshold value, the multimedia processor 50 proceeds to step S175. Otherwise, the multimedia processor 50 proceeds to step S171. move on. In step S171, the multimedia processor 50 increments the count value Cr by one. In step S173, the multimedia processor 50 decrements the coordinate X by one, and proceeds to step S169.

  The count value Cr at the time when Dif [X] [Y]> ThL is determined in step S169 corresponds to the distance RT or RB in FIG. In step S165, when Ytb = minY, Cr = RT, and when Ytb = maxY, Cr = RB.

  In step 175, the multimedia processor 50 compares the distances Cl and Cr. If the distance Cl is greater than the distance Cr in step S177, the process proceeds to step S179, and otherwise, the process proceeds to step S181.

  In step S181, “minX” is substituted for “Xtp [M]” and “Ytb” is substituted for “Ytp [M]”. On the other hand, in step S179, “maxX” is substituted for “Xtp [M]” and “Ytb” is substituted for “Ytp [M]”.

  Here, the coordinates (Xtp [0], Ytp [0]) are the coordinates of the first extraction point described in FIG. 6, and the coordinates (Xtp [1], Ytp [1]) are the coordinates of the second extraction point. Coordinates.

  In step S183, the multimedia processor 50 increments “M” by one, and proceeds to step S185. When the loop from step S153 to step S185 ends, the process returns.

Predict. In step S203, the multimedia processor 50 predicts the position (Xnr, Ynr) of the current right extraction point from the past (previous and previous) right extraction point positions (XR, YR). Here, the left extracted point (Xnl, Ynl) corresponds to the predicted position TPLp in FIG. 7, and the position (Xnr, Ynr) of the right extracted point corresponds to the predicted position TPRp.

  In step S205, the multimedia processor 50 substitutes “0” for “M”. In step S207, the multimedia processor 50 calculates a distance Dl between the predicted position (Xnl, Ynl) and the extraction point (Xtp [M], Ytp [M]). In step S209, the multimedia processor 50 calculates a distance Dr between the predicted position (Xnr, Ynr) and the extraction point (Xtp [M], Ytp [M]).

  Here, the extraction points (Xtp [0], Ytp [0]) are the first extraction points obtained by the routine of FIG. 13, and the extraction points (Xtp [1], Ytp [1]) are the same as those in FIG. This is the second extraction point obtained by the routine. When M = 0, the distance Dl corresponds to the distance LD1 in FIG. 7, and the distance Dr corresponds to the distance RD1. When M = 1, the distance Dl corresponds to the distance LD2 in FIG. 7, and the distance Dr corresponds to the distance RD2.

  In step S253, when the multimedia processor 50 detects a pixel having a threshold value ThL or less as a result of the scan in step S247 or S251, the multimedia processor 50 considers that the two retroreflective sheets 15L and 15R have been photographed, and proceeds to step S255. If no pixel equal to or less than the threshold ThL is detected, it is considered that only one of the retroreflective sheets 15L and 15R has been detected, and the process proceeds to step S259.

  In step S255, the multimedia processor 50 sets “11” (indicating that the two retroreflective sheets 15L and 15R have been photographed) to the sheet number flag SN. In step S257, the multimedia processor 50 turns on the left open flag OL and the right open flag OR. On the other hand, in step S259, the multimedia processor 50 sets “10” (indicating that only one of the retroreflective sheets 15L and 15R has been captured) to the sheet number flag SN.

Referring to FIG. 16, in step S271, the multimedia processor 50 determines whether or not the sheet number flag SN is “10”, that is, only one of the retroreflective sheets 15L and 15R has been photographed. If YES, the process proceeds to step S273 to identify the left or right retroreflective sheet. Otherwise, the process returns.

  In step S273, the multimedia processor 50 calculates the distance Dlm between the predicted position (Xnl, Ynl) and the midpoint (XM, YM). In step S275, the multimedia processor 50 calculates a distance Drm between the predicted position (Xnr, Ynr) and the midpoint (XM, YM). The midpoint (XM, YM) is obtained in step S71 of FIG. The predicted position (Xnl, Ynl) is obtained in step S201 in FIG. The predicted position (Xnr, Ynr) is obtained in step S203 in FIG.

In step S326, the multimedia processor 50 refers to the central stop flag to determine whether or not the drum image 36C is rotating. If it is rotating, the multimedia processor 50 proceeds to step S328. Otherwise, the multimedia processor 50 proceeds to step S305. In step S328, the multimedia processor 50 turns on the central stop flag.

  After “NO” is determined in step S324, in step S330, the multimedia processor 50 determines whether or not the previous left extraction point overlaps the right stop button 34R. If they overlap, the right stop button 34R is The process proceeds to step S332 assuming that the object has been grasped, and the process proceeds to step S305 otherwise. In step S332, the multimedia processor 50 refers to the right stop flag, determines whether or not the drum image 36R is rotating, proceeds to step S334 if it is rotating, otherwise proceeds to step S305. In step S334, the multimedia processor 50 turns on the right stop flag.

  After step S317, S322, S328, or S334, or after “NO” is determined in step S330 or S332, in step S305, the multimedia processor 50 performs any gripping operation based on the cursor 30R. It is determined. Details are the same as in step S303. However, in step S310, “left open flag OL” is read as “right open flag OR”, and in steps S312, S318, S324, and S330, “left extracted point” is read as “right extracted point”.

  In step S341, the multimedia processor 50 determines whether or not the stopping flag is on. If it is on, the multimedia processor 50 returns. If off, the multimedia processor 50 proceeds to step S342.

Referring to FIG. 19, in step S370, multimedia processor 50 sets the coordinates of cursor 30L at a position corresponding to the left extracted point (XL, YL) converted to screen coordinates, and is converted to screen coordinates. The coordinates of the cursor 30R are set at a position corresponding to the right extraction point (XR, YR). The multimedia processor 50 sets the image data of the cursor 30L with the palm open when the left open flag OL is on, and the cursor with the hand clasped when the left open flag OL is off. 30L image data is set. Further, the multimedia processor 50 sets the image data of the cursor 30R with the palm open when the right open flag OR is on, and the cursor with the hand clasped when the right open flag OR is off. 30R image data is set.

Since these operations are performed by opening or closing the palm to direct the input device 3 to the image sensor 54 or to hide it from the image sensor 54, the actual drum, the actual lever, the actual button, and them are driven. No mechanism is required, it is difficult to break down, and a slot machine can be configured with space saving, simple and low cost. In addition, a slot machine that can be operated without contact can be provided.

  Further, the player can operate or change the target by moving the cursor 30 with the palm open, overlapping the target, and clenching the hand to hide the input device 3. Therefore, the player can give an input by an operation as if holding the target. As a result, it becomes a hand exercise for the player, and can also be used for rehabilitation.

  Furthermore, since the slot machine can be driven simply by opening or closing the palm, even an infant, an elderly person, a physically handicapped person or the like can easily enjoy the slot machine.

  In the present embodiment, since the player uses both hands, not only the dominant hand but also the other hand is moved equally. As a result, exercise or rehabilitation of both hands can be performed in a well-balanced manner.

  Further, in the present embodiment, since the infrared light irradiated by the retroreflective sheet 15 of the input device 3 is retroreflected, the image of the retroreflective sheet 15 is clearly reflected in the captured image, and the retroreflective sheet 15 is detected. Becomes easier. Moreover, since the retroreflective sheet 15 is detected based on the difference image at the time of lighting and extinguishing, noise due to light other than the reflected light from the retroreflective sheet 15 can be removed as much as possible, and the retroreflective sheet 15 can be detected with high accuracy.

  Further, in the present embodiment, an infrared light emitting diode 9 is provided as a light emitting means, and the image sensor 54 responds only to infrared light through the infrared filter 20. Thus, the image sensor 54 does not respond to light other than infrared light, and can remove noise light sources such as moving light sources and blinking light sources (fluorescent lamps, etc.) including light other than infrared light. Become.

  The present invention is not limited to the above-described embodiment, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

  (1) Transparency of the transparent body 17 includes translucency and colored transparency.

  (2) In the above, an example in which the middle finger is passed through the input device 3 has been described. However, the number of fingers to be inserted and the number thereof are not limited thereto.

  (3) The shape of the input device is not limited to the shape of the input device 3 described above. Further, a weight having a predetermined weight can be incorporated in the input device so that the player can move his / her hand in a loaded state.

  (4) Instead of attaching a reflecting member such as the retroreflective sheet 15 to the input device 3, a self-luminous device such as an infrared light emitting diode can be attached. In this case, the information processing apparatus 1 does not require the infrared light emitting diode 9. Further, without using an input device, a subject (for example, a hand itself) can be photographed by an imaging device such as an image sensor or a CCD, and the motion can be detected by analyzing the image.

  (5) In the above description, the player has performed the “gripping” operation by placing the cursor 30 on the target in the shooting state and then switching to the non-shooting state. However, the player simply performs an operation of placing the cursor on the target. It can also be made.

  (6) In the above description, play is performed using both hands, but it is also possible to play one hand at a time.
