In the drawings,
Hereinafter, the embodiments embodying the present invention will be described with reference to the drawings.
At first, the first system embodiment according to the present invention will be described with reference to
This image display system 1 is constructed from: a screen device 10 on which an image is focused; an image control device 30 for supplying image data; a projecting device 20 for projecting the image on the screen device 10 based on the image data supplied from the image control device 30; an image taking device 40 for taking a rear image of the screen device 10, the rear image being formed so as to include a shadow PS of an indication portion P; a position detection device 50 for receiving image data of the rear image of the screen device 10 output from the image taking device 40 and for determining the position of the shadow PS of the indication portion P based on the image data and outputting the position information; and a main control device 60 for transmitting to the image control device 30 the image to be projected on the screen device 10 through the projecting device 20, based on the position information output from the position detection device 50. The screen device 10, the projecting device 20 and the image control device 30 constructs an image display device 70 to display the image for a user U.
The screen device 10 has transparency, therefore light coming to both the front and rear planes can pass therethrough. The screen device 10 is, for example, a transparent screen for a liquid crystal projector. And when a user U sees the front plane of the screen device 10, the user U sees as if the optical image projected toward the rear plane of the screen device 10 by the projecting device 20 is focused on the screen device 10, as a result, the user U can see and recognize the image projected by the projecting device 20 corresponding to the image data.
The indication portion P is the indicating tool or means through which the user U indicates a desirable portion of the image displayed on the front plane of the screen device 10. For example, the indication portion P is the user's hands (including arms) or an indicating stick. The indication portion P is illuminated by a light source LS, thus the shadow PS of the indication portion P is seen on the screen device 10. Since the screen device 10 has transparency, the shadow can be seen on the rear plane of the screen device 10 when the user U sees the rear plane of the screen device 10. Here, the light source LS may be the natural light source such as the sun or may be an illumination device provided in the circumference that the image display system 1 is arranged or may be an illumination device such as a fluorescent tube arranged in the image display system 1.
The projecting device 20 is constructed from an optical projecting system which can project the optical image on the screen device 10 based on the image data. For example, the projecting device 10 is the liquid crystal projector (DLP (Digital Liquid crystal Projector)). Preferably, the light source LS is a light source which emits white light. And based on that white light passes through the screen device 10, the area in the shadow PS of the indication portion P is blackly seen on the rear plane of the screen device 10 and the area other than the shadow PS is whitely seen, therefore an image similar to the black and white image can be obtained.
The image taking device 40 is a device to produce image data of the rear plane of the screen device 10 and is, for example, constructed from a digital camera, a digital video camera, a CCD camera unit and the like.
The image control device 30 is a device having the position detection device 50, the main control device 60, a calculation processing device (CPU), a main memory (RAM), a read only memory (ROM), an input and output device (I/O) and an external memory device such as a hard disc device if necessary, and is, for example, constructed from an information process device such as a computer, a work station, a LSI chip and the like. And it is stored in the ROM or the hard disc device programs to operate the information process device as the image control device 30, the position detection device 50 or the main control device 60, and these programs are stored in the main memory and the CPU executes these programs, thereby the image control device 30, the position detection device 50 or the main control device 60 are realized by the information process device. Further, it is not necessary to store the above programs in the memory device provided in the information process device, and the programs may be provided from the external device (for example, a server of ASP (Application Service Provider) and the provided programs may be stored in the main memory.
The image control device 30, the position detection device 50 and the main control device 60 may be realized by an individual information process device, respectively and one information process device may function as the image control device 30, the position detection device 50 and the main control device 60.
The image control device 30 stores plural image data to show to the user U and reads out the necessary image data corresponding to the instruction from the main control device 60. Further, the image control device 30 conducts image process if necessary and provides the image data to the projecting device 20.
The position detection device 50 receives the image data of the rear plane in the screen device 10 output from the image taking device 40 and conducts the image process necessary for the above image data, thereby the position detection device 50 detects the position of the shadow PS of the indication portion P and outputs such detected position data as the position information. As the image process, there exist a threshold process to extract the area of the shadow SP and an edge process to extract an outline of the shadow PS. The position detection device 50 produces the position information of the shadow PS by utilizing the area of the shadow PS obtained by the edge process and the coordinate position information of pixels of the outline.
The main control device 60 has function to wholly control operation of the image display system 1 and instructs the timing to output which image data to the image control device 30 and transmits the instruction to change the image data to the image control device 30 corresponding to the position information of the shadow PS from the position detection device 50.

For example, the dealer 801 displayed on the front display portion 1302 is displayed so that he changes his face direction or body direction so as to exactly correspond to the position according to the position information.
On the table screen 1306, the image shown in
Returning to
A plurality of player terminal portions 1505A˜1505N are connected to the game control portion 1502. Each of the player terminal portions 1505 has bill validation function and bet input function. Here, the bill validation function is function that coins, bills, prepaid card, credit card are received from the player and these are dealt as the credit (medal/coin) used in the gaming machine 1300 and further payout of the credit (medal/coin), which the player owns at the time that payout instruction is done by the player, is conducted corresponding to the player's payout instruction. And the bet input function is function that the bet number/money/the credit number in the game are determined. The player conducts the game through the player terminal portion 1505 and the indication portion P.
Next, process for detecting the position on the table screen 1306 indicated by the hand of the player will be described.
The sensor 1305 emits scanning light so as to pass over the table screen 1306. And the sensor 1305 rotates the scanning light from right to left or from left to right so that the sensor 1305 becomes the center of rotation, thereby scans the entire area over the table screen 1306. For example, the sensor 1305 repeats emission of the scanning light and reception of the reflected light while rotating the emitting direction of the scanning light by an interval of 0.5 degrees.
In the embodiment, based on position detection by the sensor 1305, it can determine the player who indicates the position. In the gaming machine 1300, five stools 1601A˜1601E are arranged so that the maximum five players can sit thereon. And the area that each player can reach is limited. At the front position of the player sitting on the stool, player terminal portions 1505A˜1505E assembled in the table portion 1301 are arranged. In each of the player terminal portions 1505A˜1505E, a bet button, a cancel button and a payout button (not shown) are provided. Through these buttons an input instruction by the player is accepted.
Areas 1602A˜1602E shown in
According to the above method, it can be done that chip color (for example, red, blue, yellow, green, white) that each player uses is determined and such chip color is displayed in a place on the table screen 1306 indicated by the position information based on the detected position information.
Here, in the above embodiment, although it is constructed so that the entire area of the table screen 1306 is scanned by one sensor 1305, the present invention can be realized in a case that a plurality of sensors 1305 are provided and each of the sensors 1305 scans an area allotted on the table screen 1306. For example, it may be constructed that two sensors 1305 are provided and one sensor 1305 scans the right half area on the table screen 1306 and the other sensor 1305 scans the left half area on the table screen 1306.
According to the position detection method mentioned above, even if plural players indicate the positions on the table screen 1306 at the same time, each player corresponding to each of the indicated positions can be recognized.
At first, the sensor 1305 conducts the position detection process (step S1901). The sensor 1305 scans over the table screen 1306 by the scanning light and determines whether or not reflection of the scanning light exists. If the reflection of the scanning light exists, the sensor 1305 measures strength and light quantity of the reflected light and specifies the direction of the reflected light and the distance to the indication portion P, thereby conducts calculation about the position.
Next, the sensor 1305 outputs the calculated position as the position information (for example, x, y coordinate values) (step S1902). Here, the sensor 1305 may output both the position information and the discrimination information of the player (for example, player's number).
The position information is output to the game control portion 1502. The game control portion 1502 determines the image to be displayed on the table screen 1306 and/or the front display portion 1302, based on the position information received, and instructs the screen image control portion 1501, the DLP 302 and the front display control portion 1504 to conduct the image display process (step S1903). For example, if the game control portion 1502 determines the position information as indication of any of the areas 901, 902, 903 for betting “PLAYER”, “BANKER”, “DRAW”, the game control portion 1502 instructs the screen image control portion 1501 to display chip image indicated within such areas, thereby the screen image control portion 1501 produces image data corresponding to the instruction.
As mentioned above, it can be realized the gaming machine 1301 in which the table screen 1306 is utilized for both the image display device and the input device.
Next, the third gaming machine embodiment according to the present invention will be described.
