DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic diagram for explaining a stereoscopic video display game machine having a head fixing position confirmation function according to the present invention, where (a) shows a side view and (b) shows a plan view of a head fixing part. ing.
The player 3 sits on the seat 6 of the game machine 1 and places the head 3a against the head fixing portion 5 to position both eyes. The player 3 can see a three-dimensional image by viewing images projected from the right-eye and left-eye projectors (not shown) on the lenticular screen 2.
[0007]
If the three-dimensional image is shifted in any direction of the arrow A with respect to an appropriate position, it cannot be clearly seen. That is, the images reaching the right eye 4a and the left eye 4b do not enter the eyes accurately. Therefore, before the game is started, the game machine 1 displays the first video and the second video for the left and right eyes, and the player performs a confirmation operation in accordance with instructions from the game machine. This confirmation operation can be performed even during the game if necessary.
[0008]
FIG. 2 is a diagram for explaining an operation for confirming the head fixing position.
(A) is an example when the background is a mountain and the sky, and the confirmation display is the sun, and the video 7a viewed with the left eye is the background of the mountain and sky and the confirmation display sun. The video seen with the right eye displays only the background mountains and sky. When viewed with both eyes, it looks like video 8.
As shown in (b), when the player first meditates with the right eye and looks with the left eye, the images of the mountains, the sky and the sun can be clearly seen at the proper positions. Next, if you meditate with your left eye and look with your right eye, you can see only the sky and mountains, and the sun will disappear if you are in the right position.
Any order may be used to meditate.
[0009]
FIG. 3 is a circuit block diagram showing an embodiment of a circuit of a stereoscopic video display game machine having a head fixed position confirmation function according to the present invention.
In this figure, the printed circuit board (PCB) for the right eye is the same as the PCB for the left eye, and is omitted.
The input / output circuit 15 is connected to the input / output circuit of the right-eye PCB, and the left-eye and right-eye images are synchronized.
The ROM 14 stores a program for controlling the entire game, and the RAM 13 serves as a work area for the CPU 11.
An input signal from the operation unit 9 is input to the CPU 11 via the input control circuit 10. The CPU 11 performs an operation based on the program and the input signal, and sends information for creating a three-dimensional image to the 3D image generation circuit 12.
[0010]
The 3D image generation circuit 12 includes a three-dimensional arithmetic circuit that converts the three-dimensional coordinates of the polygon data into a viewpoint coordinate system having the player as the origin, a perspective conversion circuit that converts the three-dimensional coordinates into two-dimensional coordinates on the screen, and perspective conversion. The 3D video signal is generated by a clipping circuit that determines whether or not the polygons that have entered the screen enter, a sorting circuit that rearranges each polygon based on the Z representative value, and the like. The left-eye projector 16 projects this image on the lenticular screen 2. A portion including the left-eye projector 16 and the right-eye projector corresponds to the projection display means.
[0011]
FIG. 4 is a diagram showing an embodiment of a functional block of the CPU.
The left-eye and right-eye CPUs, which are image generation means, determine the left or right output determination unit 17 for determining whether they are right or left, the left / right image generation unit 18 for generating left and right images, and the image output unit 19 for outputting background images. , A confirmation display output unit 20 for outputting a confirmation display object and a count unit 20a. The CPU sends a video signal with a confirmation display object or a video signal without a confirmation display object to each 3D image generation circuit 12 depending on whether it is for the right eye or the left eye.
[0012]
FIG. 5 is a flowchart for explaining the confirmation operation according to the present invention.
When the confirmation operation starts, the left and right output determination units 17 of the right-eye and left-eye CPUs determine whether they are for the right eye or the left eye (step (hereinafter referred to as “S”) 401). The left-eye left and right image generation unit 18 generates a left-eye image (S402). The left and right video output unit 19 outputs a background image (mountain and sky in this example), and the confirmation display output unit 20 outputs a confirmation display object (sun in this example) (S403, S404).
On the other hand, the right-eye left and right image generation unit 18 generates a right-eye image (S405). The left and right video output unit 19 outputs a background image (in this example, mountains and sky).
[0013]
Since the game machine instructs by voice whether to meditate the right eye or the left eye, the player meditates the right eye according to the instruction and watches the video for the left eye with the left eye. Furthermore, meditate the left eye and watch the video for the right eye with the right eye. If it looks like FIG.2 (b), it can be judged that the fixed position of a head is an appropriate position.
The count unit 20a starts counting from the time when the video is output, and monitors whether or not a predetermined time (for example, 5 seconds) has elapsed (S408). The output of the confirmation display output unit 20 is stopped (S409).
[0014]
【The invention's effect】
As described above, the present invention has the confirmation display on the lenticular screen before or during the game after the player sits on the seat of the game machine and the head of the player is positioned at the head fixed position. Since the first image and the second image that does not display the confirmation display object are displayed, the confirmation operation can be performed depending on whether the confirmation display object is present when the image is viewed only with the left eye and only with the right eye. The player can confirm whether or not the right and left images are correctly viewed simply and quickly by looking at one point and meditating alternately with the other eye.
