Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simulation apparatus and an image synthesizing method thereof, and more particularly, a simulation apparatus and an image synthesizing method thereof for providing a virtual three-dimensional simulation space as a highly realistic visual field image. The present invention relates to a game device formed by using.

[0002]

2. Description of the Related Art Conventionally, an image simulating a scene from the driver's seat of a dressing car is displayed on a display, and the image is changed according to the operation of the player, as if the racing car is running, 2. Description of the Related Art There is known a drive game device that plays a game by giving the player the feeling of driving a racing car.

In such a game device, the game screen displayed on the display is made closer to the visual field image of the actual player, so that the reality can be enhanced and the fun of the game can be remarkably improved.

Recently, with the development of computer graph fix, a computing device is made to compute a three-dimensional image to construct a computational three-dimensional space (virtual three-dimensional space) and an arbitrary position (viewpoint) in the space. It has been established that a field-of-view image viewed from above is synthesized and displayed on a display, and even if the viewpoint moves in space, the changing field-of-view image is displayed on the display in real time. In this case, the more realistic the virtual three-dimensional space to be constructed is as in the real world, the visibility image displayed on the display will be closer to the real world captured image as long as the calculation limit is not exceeded. It will be rich in. If this is applied to a drive game, a racing car or a virtual player (viewpoint) driving the racing car is set in the virtual three-dimensional game space, and the racing car and the virtual player are controlled by the virtual three-dimensional game according to the player's operation.
By moving in the three-dimensional space and displaying the visual field from the racing car or virtual player on the display, the player feels as if he / she is driving in the virtual three-dimensional space in the racing car. Can be obtained, and a more realistic drive game can be played.

However, in these drive games, when a tunnel is provided on the course in order to change the course, the following problems occur.

That is, in the real world, immediately after the player enters the tunnel, it takes a certain time for dark adaptation in which the player's pupil expands in response to the decrease in the amount of light in the field of view. Therefore,
During that time, the player cannot deal with the darkness of the tunnel and feels as if the field of vision becomes dark. Immediately after the player leaves the tunnel, it takes a certain amount of time for light adaptation in which the pupil of the player contracts in response to an increase in the amount of light in the field of view. Therefore, during that time, the player cannot respond to the brightness of the outside world, and feels as if the field of vision is dazzling and whitish.

The incompatibility of light-dark adaptation, which is such a physiological phenomenon of human beings, occurs when there is a significant light amount difference or light amount change within the human visual field.

[0008]

However, none of the conventional game devices or simulation devices reproduce the visual field image on the game screen due to the incompatibility of the light-dark adaptation. That is, conventionally, the screen at the time of dark adaptation completion was displayed on the game screen immediately after entering the tunnel. Immediately after exiting the tunnel, the screen for completion of light adaptation was displayed.

[0009] Therefore, even in such a case, the game screen which is rich in reality gives a feeling of strangeness, unlike the actual visual field of a human being in such a case.

That is, when there is a game situation in which a human causes a light-dark adaptation failure such as a light-dark adaptation delay, a visual field image caused by a light-dark adaptation failure such as a human physiological phenomenon such as a light-dark adaptation failure is displayed on the game screen. When the above is reproduced, the game device becomes more realistic, and the player can enjoy the world of virtual reality without a sense of discomfort, but conventionally there has been no game device or simulation device focusing on such a point.

The present invention has been made in view of the above problems, and an object thereof is to recreate the incongruity of human light-dark adaptation caused by a difference in the amount of light within the field of view on a simulation screen, which is highly realistic. It is an object of the present invention to provide a simulation device and an image synthesizing method, or a game device formed by using such a simulation device.

[0012]

In order to achieve the above object, a simulation device according to the invention of claim 1 is a simulation device for synthesizing an image simulating a visual field of a human and displaying it on a display. Light and dark adaptation production means for producing the incompatibility of human light and dark adaptation caused by the difference in the amount of light in the interior, and brightness setting means for changing and setting the brightness of the display image, wherein the light and dark adaptation production means is the simulated field of view. Is a brightness change determining means for determining whether or not a simulation condition causes a mismatch of light and dark adaptation due to a change in light amount, and the brightness change determining means determines that the brightness is a simulation condition causing a mismatch of light and dark adaptation. And a brightness change instruction means for instructing the setting means to change the brightness.

The image synthesizing method according to the invention of claim 6 is
A method for synthesizing an image that simulates a human visual field by using a luminance setting means for changing and setting the luminance of a displayed image and displaying the image on a display. The brightness change determination step of determining whether or not the simulated field of view is a simulation situation causing a mismatch of light and dark adaptation due to a change in light amount. And a brightness change instructing step for instructing the brightness setting means to change the brightness when it is determined in the brightness change determining step that the light and dark adaptation is incompatible.

The simulation apparatus of the present invention has a brightness setting means for setting the brightness on the display. Therefore, when trying to simulate a significant change in the amount of light in the field of view in the image displayed on the display,
By changing the brightness of the display image, it is possible to effectively produce the incongruity of the light-dark adaptation of humans on the display screen.

Specifically, in the case of producing the dark adaptation incompatibility, the brightness of the display image is reduced to display a dark screen while suppressing the amount of light, and in the case of producing the light adaptation incompatibility, the display image is displayed. By increasing the brightness of, the amount of light is increased and a whitish screen is displayed. In this way, it is possible to reproduce on the simulation screen a dark field-of-view image caused by a mismatch of light-dark adaptation or a dazzling, whitish field-of-view image.

As a method of judging the simulation situation in which the brightness change judgment means causes a mismatch of light and dark adaptation,
It is also possible to detect a virtual amount of light in the field of view displayed on the display and judge based on the change. In addition, a simulation situation in which a change in the light amount is predicted may be set in advance as a determination condition based on the content of the simulation, and the determination may be performed based on the determination condition.
For example, in the case of a drive simulation, it is predicted that light and dark adaptation will be incompatible at the entrance and exit of the tunnel, so whether or not the entrance and exit of the tunnel is set as a judgment condition, and the simulation condition satisfies the judgment condition. Sometimes it is judged that there is a mismatch of light and dark adaptation.

Therefore, according to the present invention, it is possible to reproduce on the simulation screen the same visual field image as that in which a change in the amount of light occurring in the human visual field causes the incompatibility of human light and dark adaptation. An apparatus and an image synthesizing method thereof can be provided.

As a method of instructing the brightness setting means to change the brightness by the brightness change instructing means, the brightness changing coefficient i for instructing the change rate of the brightness is as follows.
May be set and instructed.

That is, the brightness change instruction means is such that the brightness setting means makes a brightness change coefficient i for each light of blue, green and red constituting the display screen or common to each light, and each light when the brightness is not changed. Let r be the brightness of each light, r ^{′ be} the brightness of each light after the brightness change, and k be the proportional constant, and an instruction to change the brightness is given so as to satisfy r ^′ = i × r × k.

By doing so, it is possible to instruct to change the brightness for producing the light-dark adaptation regardless of the specific brightness value of each light after the image combination.

As the brightness setting means, for example, a gamma correction means of a display may be used.

The simulation apparatus according to the second aspect of the present invention is a simulation apparatus for displaying a visual field image of a virtual player in a three-dimensional simulation space on a display for a player, and performs calculation for forming the three-dimensional simulation space. Three-dimensional space calculation means, and 3 formed and calculated by the three-dimensional space calculation means
In the three-dimensional simulation space, the three-dimensional space computing means includes an image synthesizing means for synthesizing a visual field image seen from the viewpoint position of the virtual player and a brightness setting means for changing and setting the brightness of the display image. The image synthesizing means performs depth cueing processing for bringing the color of the display object of the display image closer to a predetermined color by color complementation, which includes a light-dark adaptation effect producing means for producing an incompatibility of the light-dark adaptation of human being caused by the difference in the amount of light inside. And a brightness change determining means for determining whether or not the virtual player in the three-dimensional simulation space is in a simulation situation that causes a mismatch of light and dark adaptation due to a change in light amount. It is a simulation situation in which the brightness change determination means causes a mismatch of light and dark adaptation. In the case of disconnection, the brightness change instructing means for instructing the brightness setting means to change the brightness and part or all of the virtual player's field of view in the three-dimensional simulation space are incompatible with the light-dark adaptation due to the difference in light amount with other parts. The color change judging means for judging whether or not it is a simulation situation in which the color appears to change to a predetermined color, and the depth cue when the color change judging means judges in the simulation situation that the color changes to the predetermined color. The ing processing means includes a color change instructing means for instructing to perform a calculation for bringing a color of a display object forming part or all of the virtual player's field of view close to a predetermined color.

According to the seventh aspect of the image synthesizing method, the luminance synthesizing means for changing and setting the luminance of the display image is used, and the image synthesizing for displaying the view image of the virtual player in the three-dimensional simulation space on the display. In the method, a three-dimensional space calculation step for forming and calculating the three-dimensional simulation space, and a visual field image seen from the viewpoint position of the virtual player in the three-dimensional simulation space formed and calculated in the three-dimensional space calculation step are image-synthesized. And a three-dimensional space calculation step, the three-dimensional space calculation step includes a light-dark adaptation production step for producing a non-conformity of human light-dark adaptation caused by a light amount difference in the visual field of the virtual player, and the image synthesis step includes Depth that makes the color of the displayed object in the displayed image closer to the specified color by complementing Including a depth cueing processing step for performing a winging process, wherein the light-dark adaptation effecting step is a brightness change for judging whether or not the virtual player in the three-dimensional simulation space is in a simulation situation that causes a mismatch of light-dark adaptation due to a change in light amount. In the determination step and the brightness change determination step, when it is determined that the simulation situation causes a mismatch of light and dark adaptation, a brightness change instruction step for instructing the brightness setting means to change the brightness, and a virtual image in the three-dimensional simulation space. A color change determination step of determining whether or not a part or all of the player's field of view is in a simulation state in which it appears to change to a predetermined color due to a mismatch of light and dark adaptation due to a light amount difference from another portion, and the color change determination. In the step, stains appearing to change to the predetermined color A color change instructing step for instructing to perform a calculation to bring the color of the display object forming part or all of the virtual player's field of view closer to a predetermined color in the depth cueing processing step. It is characterized by including.

In addition to the constituent requirements of claim 1, the simulation apparatus of a second aspect of the present invention further uses a depth cueing process to determine the color of the display object of the display image in order to further perform the light-dark adaptation effect. It is configured to include a means for approaching the color in the configuration requirement. Therefore, in addition to the brightness change, by performing depth cueing processing that brings the color of the display object on the display closer to a predetermined color, it is possible to perform an effective light-dark adaptation effect with a more natural image.

For example, in the case of producing a dark adaptation incompatibility,
In addition to the brightness change, it is preferable to perform a depth cueing process in which the target object gradually shifts from a blackish color to a normal color in order to produce the effect until the eyes are turned off.

In addition, in the case of producing the incompatibility of light adaptation, in addition to changing the luminance, the object to be displayed is gradually changed from a whitish color to a normal color in order to produce the object until the eyes become dim. It is preferable to perform depth cueing processing as described above.

Therefore, not only when the light amount changes in the entire visual field in the simulation space, but also when the light amount in a part of the simulation space is remarkably different from the others, a visual field image in which the light and dark cannot be adapted is produced. Is effective for.

For example, in the case of driving simulation, the case where the whole field of view looks like a predetermined color changes,
For example, when exiting a tunnel or when entering a tunnel. Immediately after entering or leaving the tunnel in such a case, a dark-light adaptation may occur and the field of vision may become dark or whitish.

The case where a part of the field of view appears to change to a predetermined color is, for example, when the exit is viewed from the inside of the tunnel or vice versa. In this case, the view from the exit of the tunnel has too much light compared to the view inside the tunnel, it cannot be adapted to light, and it looks whitish. The amount of light was too small to be able to adapt to darkness,
It looks dark. Therefore, in such a case, only the depth cueing process may be performed so that a part of the color changes into a predetermined color.

As a method of judging such a simulation situation by the color change judging means, a light quantity difference in the visual field of the virtual player (viewpoint) in the simulation space is detected, and judgment is made based on the light quantity difference. Good. Further, the above-mentioned simulation situation may be set in advance as a determination condition based on the content of the simulation, and the determination may be performed based on the determination condition. That is, whether or not the virtual player (viewpoint) can see the entrance / exit of the tunnel, or whether or not the entrance / exit of the tunnel is set as a judgment condition, and when the simulation condition satisfies the judgment condition, the light / dark adaptation is not suitable. Is determined to occur.

Further, the color change instructing means has information necessary for the depth cueing processing, for example, a display object to be the depth cueing processing, back color information which is a color to which the display object is brought closer, and a degree of approaching. It is also possible to set the information including the depth information that decides to specify the change.

Therefore, according to the present invention, it is possible to reproduce on the simulation screen the same visual field image as that in which the difference in the amount of light within the visual field causes the incongruity of light and dark adaptation of human beings, so that the simulation apparatus with a high degree of reality can be obtained. It is possible to provide the image synthesizing method.

Further, by performing depth cueing processing for adjusting a part of the field of view to a predetermined color such as white or black, a part of the field of view of the virtual player (viewpoint) in the simulation space is obtained. However, it is possible to produce a visual field image when light and dark cannot be adapted.

Further, in the simulation apparatus according to the invention of claim 3, in any one of claims 1 and 2, the brightness change instruction means changes the brightness for each light of blue, green and red constituting the display screen. It is characterized by instructing to do.

By doing so, it is possible to change the brightness of the display image for producing the light-dark adaptation with various colors, not only from pure black to pure white. Therefore, the brightness should be changed with a color according to the simulation situation. You can

A simulation apparatus according to a fourth aspect of the present invention is a simulation apparatus for displaying a field-of-view image of a virtual player in a three-dimensional simulation space on a display for a player, and forms and calculates the three-dimensional simulation space. Three-dimensional space calculation means, and 3 formed and calculated by the three-dimensional space calculation means

Change judgment means,
When the color change determining means determines that the simulation situation is such that the color changes to the predetermined color, the depth queuing processing means causes the depth of the virtual player to change the color of the display object to a predetermined color. And color change instructing means for instructing to perform a calculation to bring

Further, the image synthesizing method of claim 8 is an image synthesizing method for displaying a view image of a virtual player in a three-dimensional simulation space on a display to a player, and forms and calculates the three-dimensional simulation space. The three-dimensional space calculation step includes a three-dimensional space calculation step and an image combination step of image-synthesizing a view image seen from the viewpoint position of the virtual player in the three-dimensional simulation space formed and calculated in the three-dimensional space calculation step. Includes a light-dark adaptation production step for producing an incompatibility of human light-dark adaptation caused by a difference in the amount of light in the visual field of the virtual player, and the image combining step brings the color of the display object of the display image close to a predetermined color by color complementation. Depth cueing process for depth cueing In the light / dark adaptation producing step, a part or all of the virtual player's field of view in the three-dimensional simulation space appears to change to a predetermined color due to a light / dark adaptation incompatibility due to a light amount difference from other parts.

A color change instructing step for instructing to perform a calculation to bring the color of the display object forming a part or all of the above into a predetermined color.

The simulation apparatus of the present invention has a depth cueing processing means for performing a depth cueing process to bring the color of the display object of the display image closer to a predetermined color by color complementation. Therefore, by bringing the color of the display object of the display image closer to the predetermined color, it is possible to effectively produce the nonconformity of the light-dark adaptation on the display screen.

Specifically, in the case of producing a dark adaptation incompatibility, in order to produce a target display object until the eyes are turned off, the target object gradually shifts from a blackish color to a normal color. Depth cueing should be performed.

Further, in the case of producing the incompatibility of light adaptation, the depth cuing in which the target object gradually shifts from the whitish color to the normal color in order to produce the effect until the eyes are turned off. It is good to perform processing.

By doing so, not only when the light amount changes in the entire field of view in the simulation space, but also when a part of the light amount in the simulation space is remarkably different from the others, a field-of-view image that cannot be adapted to brightness and darkness is displayed. Effective for directing.

For example, in the case of a drive simulation, the case where the entire field of view looks like a predetermined color changes,
For example, when exiting a tunnel or when entering a tunnel. Immediately after entering or leaving the tunnel in such a case, a dark-light adaptation may occur and the field of vision may become dark or whitish.

The case where a part of the field of view appears to change to a predetermined color is when the exit is viewed from inside the tunnel, or conversely, when the inside of the tunnel is viewed from the outside. In this case, the view from the exit of the tunnel has too much light compared to the view inside the tunnel, it cannot be adapted to light, and it looks whitish. The amount of light was too small to be able to adapt to darkness,
It looks dark. Therefore, in such a case, it is preferable to perform the depth cueing processing so that a part of the color changes into a predetermined color.

As a method of determining such a simulation situation, it is possible to detect the light amount difference in the visual field of the virtual player (viewpoint) in the simulation space and make the determination based on the light amount difference. Further, the above-mentioned simulation situation may be set in advance as a determination condition based on the content of the simulation, and the determination may be performed based on the determination condition. That is, whether or not the virtual player (viewpoint) can see the entrance / exit of the tunnel, or whether or not the entrance / exit of the tunnel is set as a judgment condition, and when the simulation condition satisfies the judgment condition, the light / dark adaptation is not suitable. Is determined to occur.

Further, the color change instructing means has information necessary for the depth cueing processing, for example, a display object to be the depth cueing processing, back color information which is a color to which the display object is brought closer, and a degree of approaching. It is also possible to set the information including the depth information that decides to specify the change.

Expressed as a shape model consisting of 512-3,.
Pre-stored in memory.

Taking the drive game as an example, the three-dimensional object 510 is a racing car that appears in the three-dimensional game space 500. In the three-dimensional game space 500, other than this, for example, as shown in FIG. Racing course 320, building 330, tunnel 332, cliff 336,
Various three-dimensional objects representing the background such as the guardrail 338 are arranged.

The racing course 320 has a plurality of corner portions 322 and is provided with ups and downs or banks depending on the location.

These three-dimensional objects are perspective-projected on the perspective projection plane 520 of the viewpoint coordinate system centering on the viewpoint 610 of the virtual player, and displayed on the display 30 as a pseudo three-dimensional image 522. For example, when the player 600 looks at the display 30 from the viewpoint 610 with the operation unit 10 in front, an image of himself / herself acting as a virtual player, sitting in the driver's seat of the racing car and positioned in the three-dimensional space 500 is displayed. You can see. When the player 600 operates a steering wheel or the like of the operation unit 10 to perform an operation such as rotation or translation of a racing car that he or she virtually rides, the position of the viewpoint 610 with respect to the three-dimensional space 500 changes, and The dimensional space 500 will be rotated and translated. Therefore, the game calculation section 100 determines the three-dimensional game space 5 based on the operation signal and the game program.
Calculations such as rotation and translation of the three-dimensional object 510 that is a racing car and other three-dimensional objects that make up 00 are performed in real time. Then, as described above, these three-dimensional objects are perspective-projected on the perspective projection plane 520 and displayed on the display 30 as a pseudo three-dimensional image 522 that changes in real time.

Therefore, the player 600 has the operation unit 1
By manipulating 0 and driving a racing car, 3
It is possible to simulate the state of participating in the race while driving the racing car in the racing course set in the three-dimensional game space 500.

When the computer graphics method is used, the shape model of the three-dimensional object 510 is created using an independent body coordinate system. That is, each polygon constituting the three-dimensional object 510 is arranged on the body coordinate system, and its shape model is specified.

Further, the three-dimensional game space 500 is constructed using the world coordinate system (XW, YW, ZW), and the three-dimensional object 510 represented using the body coordinate system.
Are located in the world coordinate system according to the motion model.

Then, with the position of the viewpoint 610 as the origin,
The data is converted to a viewpoint coordinate system in which the direction of the line of sight is set in the positive direction of the Z axis, and the respective coordinates are perspectively projected and transformed to a screen coordinate system which is the projection plane 520. In this way, the image within the field of view of the three-dimensional game space 500 that can be seen from the viewpoint 610 can be displayed on the display 30. In particular, the game calculation unit 100 according to the embodiment is configured to control the viewpoint 6 in the three-dimensional game space 500 configured by the world coordinate system.
It is formed so that the position of 10 can be changed arbitrarily.
In the embodiment, by setting the viewpoint position 610 from the rear side to the front side of the player racing car 530 during the game, the three-dimensional game viewed from the rear side to the front side of the player racing car 530 as shown in FIG. Space 5
The image of 00 can be displayed on the display 30.

In the arcade game machine of this embodiment, when the game is started, the racing car 53 driven by the player.
0 starts from the start point 340 shown in FIG. Then, when the game course 320 makes one lap and passes the checkpoint 342 within the time limit, it makes another lap of the game course. Then, when the player goes around the game course a predetermined number of times, the goal is reached, and the ranking of the player is decided.

In such a game device, the game screen displayed on the display can be made closer to the field of vision of a real person, so that the reality can be enhanced and the fun of the game can be significantly improved.

However, when a tunnel is provided on the course to give the course a change, the following problems occur.

FIG. 6 (A) shows the relationship between the change in the amount of light in the outside world (indicated by 700 in the figure) and the enlarging of the human pupil (indicated by 710 in the figure) when the person enters the tunnel from outside. 6B shows the amount of light (indicated by 720 in the figure) sensed by the human retina at that time. As shown in FIG. 6 (A), when a person enters the tunnel from outside the tunnel, the amount of light in the outside world greatly decreases, but the human pupil correspondingly expands by a (about 3 seconds). ) There is a time lag. Therefore, immediately after entering the tunnel, the amount of light 720 sensed by the human retina is as shown in FIG.
As shown in (B), it is extremely reduced, so that the human feels as if the field of vision is darkened. Then, after the lapse of a certain time a, the pupil expands to a size according to the amount of light in the external world, so that the eye becomes accustomed to so-called darkness.

FIG. 7 (A) shows the relationship between the change in the amount of light in the outside world (indicated by 700 in the figure) and the enlarging of the human pupil (indicated by 710 in the figure) when the person goes out of the tunnel. FIG. 7B shows the amount of light sensed by the human retina at that time. Figure 7
As shown in (A), when a person goes out of the tunnel and out of the tunnel, the amount of light in the outside world increases significantly,
Correspondingly, although the human pupil contracts, b (about 3 seconds)
There is a time lag of. Therefore, immediately after coming out of the tunnel, the amount of light 720 sensed by the human retina is extremely increased as shown in FIG. 7B, and the human feels as if the field of vision becomes whitish. Then, after a lapse of a certain time b, the pupil contracts to a size corresponding to the amount of light in the external environment, so that the eye becomes accustomed to the so-called brightness.

As described above, when a person actually enters or exits the tunnel, it adapts to changes in the amount of light in the outside world, but as described above, a mismatch occurs for a certain period of time a and b, so the field of vision becomes dark when entering the tunnel. When I get out again, I feel dazzling.

However, on the conventional game screen, the screen when the dark adaptation is completed was displayed even immediately after entering the tunnel. Immediately after leaving the tunnel, the screen for completion of light adaptation was displayed.

Therefore, even in such a case, the game screen rich in reality gives a feeling of strangeness, unlike the actual visual image of the human being in such a case.

Therefore, in this embodiment, an unconventional structure is adopted in which the incongruity of light and dark adaptation, which is a human physiological phenomenon, is produced on the display screen.

That is, in the game device of this embodiment, when the light quantity of the visual field of the virtual player in the virtual three-dimensional space is remarkably changed, the virtual player causes an incongruity of light and dark adaptation, and
When the virtual player cannot adjust the brightness and darkness due to a large difference in the light amount of a part of the display object in the virtual player's view in the three-dimensional space, the virtual player's view image of the virtual player who cannot adjust the brightness can be reproduced on the display screen. Has been formed.

As shown in FIG. 1, the game apparatus of this embodiment has a depth cueing processing section 280 and a brightness setting section 29.
Since 0 is included, the method of changing the brightness and the depth cueing process is used to synthesize such a visual field image. Specifically, the brightness change is used when changing the brightness of the entire display screen. For example, when a tunnel enters a tunnel, it becomes dark, and when it exits, a visual field image of a virtual player that feels dazzling is produced by changing the brightness of the entire display screen.

In this embodiment, the brightness setting section 290 is used to provide the three-dimensional space computing section 110 with a brightness change determining section 122 and a brightness change instructing section 124 in order to synthesize such a visual field image.

The brightness change determination unit 122 should cause the virtual player to become incompatible with light and dark adaptation due to a change in the amount of light that occurs in the virtual player's field of view in the virtual three-dimensional space, and as a result, produce the incompatibility of light and dark adaptation on the display screen. It is determined whether it is a game situation.

As a method of determining such a game situation, the light amount of the visual field of the virtual player in the three-dimensional game space may be detected and the determination may be made based on the change. In addition, a game situation in which a light amount change is predicted based on the game content may be set in advance as a determination condition, and the determination may be performed based on the determination condition. For example, since it is predicted that light / dark adaptation will not fit at the entrance / exit of a tunnel, set whether or not a virtual player enters or exits the tunnel as a judgment condition, and when the game condition satisfies the judgment condition, the virtual condition is set. It is determined that the player has a dark / light adaptation failure.

When the brightness change determining unit 122 determines that the game situation is to change the brightness, the brightness change instructing unit 124
Instructs the brightness setting unit 290 to change the brightness on the screen.

The brightness can be changed for each light of blue (hereinafter referred to as B), green (hereinafter referred to as G) and red (hereinafter referred to as R) constituting the display screen, or the same for each light. It can also be increased or decreased in proportion.

The brightness setting unit 290 sets the brightness of the display screen based on the instruction of the brightness change instruction unit 124 at the stage of correction before the color signal for each pixel of the display screen is determined and before being output to the screen. A change calculation is performed. The color signal represents the color of each pixel on the display screen and includes R, G, and
It is composed of information on the brightness of each color of B.

For example, assuming that the R brightness information of the color signal is r, the brightness change coefficient is i, the R brightness information output to the screen is r ^′ , and the proportional constant is k, then r ^′ = k × r × i The change setting of the displayed brightness is performed. The same applies to G and B. Therefore, in such a case, the brightness change instruction unit 124 creates the brightness change information including the brightness change coefficient i, and gives the brightness setting unit 290 an instruction to change the brightness on the screen.

The method by which the brightness change instructing section 124 instructs the brightness setting section 290 to change the brightness on the screen is not limited to the above example, but the brightness change coefficient i is added to the brightness information r of the R of the color signal. It may be configured to change settings by
Other configurations may be used.

Further, in the game device of this embodiment, 1/60
Since the image is supplied to the display every second, when changing the brightness, the brightness change instruction unit 124
An instruction for designating a luminance change is issued every second, and the luminance setting unit 290 sets a luminance change every 1/60 seconds based on the instruction.

In FIGS. 8A and 8B, the origin is the entrance point and the exit point of the tunnel, the horizontal axis is time, and the vertical axis is the rate of increase or decrease in brightness (1 when the brightness of the display screen is not changed,
It is a diagram showing how much the brightness is increased or decreased. The brightness change coefficient i is set based on the increase / decrease rate of the brightness.

At the entrance of the tunnel, the amount of light reflected on the retina of the virtual player is as shown in FIG. 6B, and it takes about 3 seconds until the eyes get used to the darkness. Therefore, during that time, 1/6
By changing the brightness of the display screen as shown in FIG. 8A every 0 seconds, a state in which the eyes of the virtual player gradually become accustomed is reproduced in the display image on the game screen. That is, near the entrance of the tunnel, the brightness change instruction unit 1
24 is the increase / decrease rate 73 of the luminance of FIG.
Based on 0, the brightness change coefficient for instructing the change of brightness is set.

At the exit of the tunnel, the amount of light reflected on the retina of the virtual player is as shown in FIG. 7B, and it takes about 3 seconds until the brightness gets used to the eyes. Therefore, 1 /
By changing the brightness of the display screen as shown in FIG. 8B every 60 seconds, a state in which the eyes of the virtual player gradually become accustomed is reproduced in the display image on the game screen.
That is, near the exit of the tunnel, the brightness change instruction unit 1
24 is the increase / decrease rate 73 of the brightness in FIG. 8B every 1/60 seconds.
Based on 0, the brightness change coefficient for instructing the change of brightness is set.

Incidentally, such an effect can be realized also by depth cueing processing, but in the present embodiment,
The brightness setting unit 290 is used. The brightness setting unit 290
Since the brightness of the entire screen is changed instead of the polygon unit,
This is because the processing load is small. Therefore, immediately after entering the tunnel or immediately after exiting the tunnel, the player's entire field of view becomes dark or bright,
The brightness of the entire screen is changed by the brightness setting unit 290, which requires less processing load.

However, since the brightness setting section 290 changes the brightness of the entire screen, when the brightness cannot be adapted due to the light amount difference in a part of the virtual player's field of view, the brightness of only the display part is changed. I can't do that. Therefore, in such a case, the depth cueing process is used.

For example, when the exit is seen from inside the tunnel, the scenery seen from the exit of the tunnel has a too large amount of light as compared with the scenery inside the tunnel, and human beings are unable to adapt to light and appear whitish. In such a case, by performing the depth cueing process, it is possible to produce a visual field image in the case where the virtual player cannot perform bright adaptation even in a part of the visual field of the virtual player in the virtual three-dimensional space.

Also, in the case of producing a light adaptation nonconformity until the eyes get used to the brightness of the outside after exiting the tunnel,
Depth cueing processing is performed on the entire visual field of the virtual player so that the whitish color gradually shifts to the normal color. By performing such processing, the scenery outside the tunnel seen by the player changes from a whitish color to a normal color from the inside of the tunnel to the outside of the tunnel. In this way, the player can feel as if he or she is causing a photopic adaptation mismatch.

On the contrary, when the inside of the tunnel is viewed from the outside world, the view from the entrance of the tunnel has a too small amount of light as compared with the view of the outside world, so that human beings cannot adapt to darkness and appear dark. In such a case, by performing the depth cueing process, it is possible to produce a visual field image when the virtual player cannot perform dark adaptation even in a part of the visual field of the virtual player in the virtual three-dimensional space.

Then, in the case of producing a dark adaptation incompatibility until entering the tunnel and getting used to the darkness in the tunnel,
In this case, the depth cueing process is performed so that the blackish color gradually shifts to the normal color for the entire visual field of the virtual player. By performing such a process, the scenery in the tunnel seen by the player returns from a dark color to a normal color from the outside of the tunnel to the inside of the tunnel. In this way, the player can feel as if he or she is causing a dark adaptation failure.

By performing such depth cueing processing in addition to changing the luminance, it is possible to perform an effective light-dark adaptation effect with a more natural image. Note that the depth cueing process uses the method of Japanese Patent Application No. 5-173698 filed by the present applicant, and a specific configuration will be omitted.

The depth cueing processing of the present embodiment is configured so that the color of the display object can be changed in polygon units. Therefore, the color can be changed regardless of whether it is a part of the display screen or the entire screen. Therefore, when a part of the visual field image is initially subject to the light-dark adaptation effect as in the case of entering and exiting the tunnel described above, the visual field image of the virtual player is combined using the depth cueing process.

In order to synthesize such a field-of-view image using the depth cueing process, in the present embodiment, the three-dimensional space calculation section 110 is further provided with a color change determination section 126 and a color change instruction section 128. .

The color change judging section 126 may not be able to adapt to the brightness and darkness of the virtual player due to a change in the amount of light that occurs in a part of the virtual player's field of view in the virtual three-dimensional space. It is determined whether or not it is a game situation in which a depth cueing process is performed to bring the color closer to a predetermined color.

As a method of determining such a game situation, the light amount of the visual field of the virtual player in the three-dimensional game space may be detected and the determination may be made based on the change. In addition, a game situation in which a light amount change is predicted based on the game content may be set in advance as a determination condition, and the determination may be performed based on the determination condition. For example, when you can see the exit from the inside of the tunnel or the entrance of the tunnel from the outside, it is expected that the color of the entrance and exit of the tunnel will appear whitish or black.
Whether or not such a game situation is set as a judgment condition.

When the color change judging unit 126 detects the incompatibility of the light-dark adaptation or the case where the light-dark adaptation cannot be performed, the depth queuing processing unit 280 is instructed to perform the calculation to bring the color of the display object on the screen close to the predetermined color. It is the color change instructing unit 128 that does this.

Since the image is supplied to the display every 1/60 seconds in the game device of this embodiment, when the color of the display object on the screen is brought close to the predetermined color, the color change instructing section 128 is used.
Is the depth queuing processing unit 28 every 1/60 seconds.
0 is instructed to perform a calculation for bringing the color of the display object on the screen close to a predetermined color.

The depth cueing processing unit 280 is for performing a process of bringing a part or all of the display object on the screen close to a predetermined color after the color of each pixel on the screen is determined. Done.

In FIG. 9, CZ is depth information. Further, A is an original color called a previous color signal, and C is a color called a back color signal which is a destination to be brought closer by color interpolation in depth cueing processing. A and C are R, G,
It is composed of luminance information of each color of B. B is depth C
The color at the Z position is obtained by the depth cueing process. As a result, the larger CZ,
That is, the closer to the back side, the closer the color B is to the color C. The depth cueing process can be realized by performing the above color interpolation calculation on the luminance of each component of RGB.

Since the depth cueing processing unit 280 can perform such depth cueing process for each polygon, it can perform a part or all of the display object on the screen.

When the depth cueing processing unit 280 performs the depth cueing process, since the display object to be the depth cueing process and the depth color signal and depth information thereof are necessary, the color change setting unit 128 The color change information including the above information is set and a change instruction is given.

FIG. 10A is a diagram showing depth information 740 when the origin is set as the entrance point of the tunnel and the color of the display object in the entrance near the tunnel entrance is approximated to the normal color by the depth cueing process. Is.

Before entering the tunnel, the scenery in the tunnel seen from the entrance of the tunnel looks dark. This is because the scenery in the tunnel has a too small amount of light as compared with the surrounding scenery, and the virtual player cannot adapt to dark adaptation. Then, shortly after the virtual player enters the tunnel, the scenery in the tunnel becomes visible. In order to produce a visual image of the virtual player in such a situation, the depth cueing process is performed on the display object forming the inside of the tunnel so as to blend into the black. At this time, the color change instructing unit 128 includes, in the color change information, the display object forming the inside of the tunnel as the display object to be processed, the black as the back color signal, and the depth information 740 about 3 times until the eyes are used. Second, FIG. 10 (A)
As shown in 740, it is set every 1/60 seconds.

By changing the depth information 740 in this way, when the user is outside the tunnel, the scenery inside the tunnel seen from the entrance of the tunnel and the scenery inside the tunnel seen from the inside of the tunnel are dark, It is possible to smoothly change to the scenery and perform a dark adaptation effect without a sense of incongruity, and the player can feel as if the eyes gradually get used to it from the state in which the dark adaptation does not match.

FIG. 10B is a diagram showing depth information 740 when the color of a display object outside the tunnel near the tunnel exit is approximated to the normal color by the depth cueing process with the origin as the exit point of the tunnel. Is.

Before leaving the tunnel, the scenery outside the tunnel seen from the exit of the tunnel looks bright and whitish. The scenery outside the tunnel has too much light compared to the surrounding scenery,
This is because the virtual player cannot adapt to light. Then, after the virtual player leaves the tunnel for a while, the scenery outside the tunnel becomes visible. In order to produce the visual field image of the virtual player in such a situation, the depth cueing process is performed on the display object that constitutes the outside of the tunnel so as to blend into white. At this time, the color change instructing unit 128 includes, in the color change information, the display object constituting the outside of the tunnel as the display object to be processed, the white as the back color signal, and the depth information for about 3 seconds until the eyes get used to it. , FIG. 10 (B) 74
As shown in 0, it is set every 1/60 seconds.

By changing the depth information 740 in this way, when inside a tunnel, the view outside the tunnel seen from the exit of the tunnel and the view outside the tunnel seen from outside the tunnel can be changed from a whitish view to a normal view. It is possible to smoothly change to a landscape and perform a light adaptation effect without a sense of incongruity, and the player can experience the sensation that the eyes gradually get used from the state in which the light adaptation is incompatible.

The depth cueing processing unit 280 does not necessarily have to be included in the image drawing unit 240, and in the case where the three-dimensional calculation unit 220 has color coordinate information such as the vertex coordinates of a polygon, for example, RGB luminance information. It may be included in the three-dimensional calculation unit 220.

FIG. 11 is a flow chart showing the effect of light-dark adaptation performed in the process of the virtual player going out of the tunnel in the present embodiment.
FIG. 9 is a diagram showing a positional relationship between the player car 530 and the tunnel 332 at that time. 13 to 16 are explanatory views of the game screen at that time.

When the player car 530 enters the tunnel 332 and the exit 326 comes into view (step 10 in FIG. 11, 530-1 in FIG. 12), the scenery 550 outside the tunnel
Looks too whitish because the virtual player can't adapt to the light because there is too much light in the tunnel. Therefore, at this time, the color change determining unit 126 determines to perform the depth cueing process, and the color change instructing unit 128 causes the depth cueing unit 280 to display an object (polygon) that constitutes the scenery 550 outside the tunnel. On the other hand, the color change information is set so that the back color is white and the depth cueing process is performed. Then, when the depth cueing processing unit 280 performs the depth cueing process based on the color change information (step 20), a game screen as shown in FIG. 13 is displayed. On this game screen, the scenery 550 outside the tunnel is displayed whitish by the depth cueing process.

In FIG. 14, the virtual player is at the exit 3 of the tunnel.
This is a view of the game screen when approaching close to 26 (530-2 in FIG. 12). The scenery 550 outside the tunnel occupies a large proportion of the display screen. The landscape of is displayed whitish by the depth cueing process. However, as shown in FIG. 10 (A), the degree of this whitishness decreases as it approaches the exit 326 of the tunnel.
Compared to 3, the color is closer to the normal color.

When the player car 530 goes out of the tunnel (step 30 in FIG. 11, 530-3 in FIG. 12), the amount of light change inside and outside the tunnel is so large that the virtual player's light adaptation becomes unsuitable. The view 530 looks dazzling and whitish.

Therefore, at this time, the brightness change determination unit 122
Decides to change the brightness, and the brightness change instruction unit 12
4 sets and instructs the brightness setting unit 290 to set the brightness change information to increase the screen brightness. Then, the brightness setting unit 2
When 90 calculates the brightness based on the brightness change information (step 40), a game screen as shown in FIG. 15 is displayed. In this game screen, the scenery 550 outside the tunnel
Is displayed with a bright, whitish and dazzling screen. For example, the mountain 560 seen in front has higher brightness than usual and is displayed as whitish.

Then, as shown in FIG. 8B,
The brightness is set so as to gradually return to the normal brightness, and as shown in FIG. 10B, the depth cueing process is performed so that the screen gradually returns to the normal hue (step 50). And about 3 seconds after leaving the tunnel,
A normal screen is displayed as shown in FIG. 14, which should be viewed while the eyes are accustomed to the brightness. Scenery 5 outside the tunnel at this time
Reference numeral 50 indicates a display screen having a normal hue and a normal hue. For example, the mountain 560 visible to the front has returned to the normal display.
