Description

  The present invention relates to a computer program and a computer system for generating a pair of virtual two-dimensional images having parallax for stereoscopic display of a virtual object on a display unit.

  In recent years, content including images that can be stereoscopically displayed using binocular parallax has been provided as content displayed on video display devices such as game machines and televisions. In such content, a proposal has been made to allow a user to more stereoscopically view a stereoscopic image to be displayed (see Patent Document 1). This patent document discloses an example in which a parallax system (parallax barrier system) that enables stereoscopic viewing with the naked eye is adopted as a stereoscopic display system.

JP2012-3350

  However, in the case of a portable game machine, for example, it is difficult to improve the stereoscopic effect because the video display device provided therein is relatively small. Therefore, with the technique described in the above-mentioned patent document, a three-dimensional object cannot be three-dimensionally displayed in a small video display device to the extent that a user can be satisfied sufficiently. In particular, in the case of three-dimensional display so as to jump out and be positioned on the front side of the screen, if the screen is small, it is difficult to create content that increases the pop-out amount.

  SUMMARY An advantage of some aspects of the invention is that it provides a computer program and a computer system that can improve a stereoscopic effect obtained by a user with respect to an object displayed on a video display device.

  A computer program according to the present invention includes a virtual space generating means for generating a virtual three-dimensional space including an object, a pair of virtual two-dimensional images having a parallax, wherein the virtual three-dimensional space is photographed by a pair of virtual cameras. And a parallax image generating means for generating a reference area that faces the virtual camera in the virtual three-dimensional space, a proximity area closer to the virtual camera than the reference plane, and a remote area on the opposite side It is made to function as a color appearance setting means for setting the color appearance as seen from the virtual camera to be different depending on the area.

  With such a configuration, the color appearance is different between the proximity region close to the virtual camera and the remote region far from the virtual camera in the virtual three-dimensional space. Therefore, it is possible to attract the user's attention to the object closer to the virtual camera than the reference plane, and to improve the stereoscopic effect of the object.

  In addition, when one object is located across the reference plane, the color appearance setting unit includes a portion included in the proximity region and a portion included in the remote region in the object from the virtual camera. It is good also as setting so that the aspect of the seen color may differ.

  With such a configuration, it is possible to improve the stereoscopic effect of the portion included in front of the reference plane for the object positioned across the reference plane.

  The reference plane may be set as a projection plane that projects the virtual three-dimensional space captured by the pair of virtual cameras.

  In general, the projection plane is set to coincide with the display plane of the video display device. Therefore, with the above configuration, it is possible to emphasize the depth expression (that is, stereoscopic effect) of the object with respect to the display surface.

  In addition, the color appearance setting unit may perform a process for increasing the attractiveness of an object existing in the proximity area.

  Further, the color appearance setting means performs at least one of a process for increasing saturation, a process for increasing lightness, and a process for increasing luminance on an object existing in the adjacent area. Also good.

  With such a configuration, it is possible to actively attract the user's attention to the object existing in the proximity area, and to improve the stereoscopic effect of the object.

  In addition, the color appearance setting unit may perform processing for reducing the attractiveness of the remote area.

  Further, the color appearance setting means may arrange a translucent object on the reference plane.

  Further, the color appearance setting means includes a process for lowering saturation, a process for lowering brightness, a process for lowering brightness, a process for superimposing transparent colors, and a process for making a monotone for the remote area. At least one of the processes may be performed.

  With such a configuration, it is possible to attract the user's attention to an object that is present in a relatively close area, and to improve the stereoscopic effect of the object.

Among these components, the CPU 31, the drawing processor 32, the audio processor 33, the input signal processor 34, the RAM 35, the ROM 36, the operation unit 44, and the media interface 45 are connected to each other via a bus 46 so as to be able to transmit data to each other. .

  The operation unit 44 is an operation unit including the cross key 8, the operation buttons 9 and 10, the L button 12 and the R button 13 shown in FIG. An operation signal corresponding to the presence or absence) is input to the CPU 31. The operation unit 44 also includes a power button 7 in addition to the operator. When the power button 7 is operated, power is supplied to each unit and the game apparatus 1 is activated to operate each operator. The input is valid.

  The media interface 45 accesses the game media 50, which is a recording medium connected from the outside of the game apparatus 1, and reads the game program 50a and game data 50b stored therein. The game program 50a is a program for executing a game to be played on the game device 1, and the game data 50b is data necessary for executing the above-described game, and includes, for example, each character and background image data, status Image data for information display such as sound data such as sound effects and BGM, message data using characters and symbols, and the like. The game media 50 may employ a semiconductor memory, UMD (Universal Media Disc) (registered trademark), which is a kind of optical disc, or the like.

  In the RAM 35, a load area for storing the game program 50a and the game data 50b read from the game media 50 in accordance with the progress of the game, and a work area for use when the CPU 31 processes the game program 50a are set. Has been. The ROM 36 stores a basic program for operating the game apparatus 1, such as a program for controlling the reading process of the game program 50a and the game data 50b stored in the game media 50.

  When the user performs an input operation for bringing the tip of the touch pen into contact with the touch panel 43 (the surface of the first display 6), the input signal processing unit 34 is based on the coordinates of the touch point on the touch panel 43. Is detected, and a signal indicating the position information is output to the CPU 31.

  The CPU 31 reads all or part of the game program 50a and the game data 50b recorded in the game media 50 into the RAM 35 through the media interface 45, and executes them according to the operation input to the touch panel 43 or the operation unit 44 by the user. And control the game progress. More specifically, when a signal is input from the touch panel 43 or the operation unit 44 by a user operation, the CPU 31 performs a predetermined game progress process corresponding to the operation signal according to the game program 50a, and the process result is displayed as a game. An image indicating the progress is displayed on the first display 6 or the second display 15 and an audio signal indicating the progress of the game is output to the speaker 16.

  The drawing processor 32 performs drawing of an image in accordance with an instruction from the CPU 31. That is, the CPU 31 determines the contents of an image to be displayed on the first display 6 or the second display 15 based on a signal input from the touch panel 43 or the operation unit 44, and draws necessary drawing data for the contents. The processor 32 is generated. The drawing processor 32 generates image data based on the generated drawing data, and writes this image data into the VRAM 40. The D / A converter 41 sequentially converts the image data output from the VRAM 40 into an analog signal and outputs (displays) it to the first display 6 or the second display 15.

  As described above, the second display 15 of the game apparatus 1 can display a stereoscopic image, and the drawing processor 32 also draws the stereoscopic image. For example, a pair of virtual cameras are arranged in a virtual three-dimensional space, and the rendering processor 32 generates data of virtual two-dimensional images for left eye and right eye that have a parallax taken with each other. This image data is recorded in an appropriate format in the VRAM 40, and further output (displayed) to the second display 15 via the D / A converter 41. The second display 15 outputs a stereoscopically viewable image by outputting the image data by an appropriate method (a parallax barrier method in the present embodiment).

  Further, the CPU 31 determines sound effects such as sound effects and BGM to be output from the speaker 16 in accordance with the progress of the game, reads out sound data for generating the sound from the RAM 35, and inputs the sound data to the sound processor 33. . That is, when a sound generation event occurs with the progress of the game, the CPU 31 reads out sound data corresponding to the sound generation event (voice data loaded from the game media 50) from the RAM 35 and inputs it to the sound processing processor 33. The audio processor 33 is configured by a DSP (Digital Signal Processor), and after giving a predetermined effect (for example, reverb, chorus, etc.) to the audio data input by the CPU 31, it is converted into an analog signal, Output to amplifier 42. The amplifier 42 amplifies the audio signal input from the audio processor 33 and then outputs it to the speaker 16.

[Functional configuration of control unit]
FIG. 3 is a block diagram illustrating a functional configuration of the control unit 30 included in the game apparatus 1. The control unit 30 of the game apparatus 1 executes the game program 50a and the game data 50b read from the game media 50, so that the game progress control means 30a, the virtual space generation means 30b, the parallax image generation means 30c, the color appearance setting means Functions such as 30d and stereoscopic image output means 30e are exhibited.

  Among these, the game progress control means 30a advances the game in accordance with the operation of the touch panel 43 or the operation unit 44 by the user, and controls actions of the player character, enemy character, and the like. The virtual space generation unit 30b generates a virtual three-dimensional space (including an object that forms a part of each character and the virtual three-dimensional space) in which a player character or an enemy character operated by the user acts. As described above, the parallax image generation unit 30c captures a virtual three-dimensional space with a pair of virtual cameras, and generates a pair of virtual two-dimensional images having parallax. The color appearance setting means 30d sets a reference plane facing the virtual camera in the virtual three-dimensional space, and the virtual camera includes a proximity area closer to the virtual camera than the reference plane and a remote area on the opposite side. The color appearance seen from the above should be different (details will be described later). The stereoscopic image output means 30e displays a stereoscopic image on the second display 15 based on a pair of virtual two-dimensional images photographed by the virtual camera. Note that the virtual camera and some objects are movable in the virtual three-dimensional space in accordance with, for example, a user operation.

[Stereoscopic image display processing]
Next, a stereoscopic image display process performed by the control unit 30 will be described. FIG. 4 is a schematic plan view showing a virtual three-dimensional space (hereinafter referred to as “virtual space”) for stereoscopic display. In the example shown here, a rectangular object 101 and a spherical object 102 forming a three-dimensional object are provided in the virtual space 100. In addition, in the virtual space 100, a pair of virtual cameras CL and CR are arranged on the left and right in order to shoot a left-eye image and a right-eye image, respectively. These virtual cameras CL and CR are arranged by a crossing method (a method of crossing the optical axes of each other). In FIG. 4, objects 101 and 102 are included in the respective angles of view. Note that a parallel method (a method in which the optical axes of the virtual cameras CL and CR are arranged parallel to each other) may be used.

  Projection planes 103 are set at predetermined positions in front of the left and right virtual cameras CL and CR. This projection plane 103 is a single plane common to the left and right virtual cameras CL and LR, and the projection plane 103 has zero parallax when viewed from the left and right virtual cameras CL and CR. In FIG. 4, the projection plane 103 is set so as to cross the middle portion of the rectangular object 101, in other words, the rectangular object 101 is located across the projection plane 103. The spherical object 102 is located farther from the projection plane 103 (away from the virtual cameras CL and CR).

  The virtual cameras CL and CR each photograph the virtual space 100 within a range that can be accommodated on the projection plane 103, and the virtual space 100 projected on the projection plane 103 is displayed in a three-dimensional manner on the second display 15. That is, the drawing processor 32 generates a pair of virtual left- and right-eye image data (for left eye and right eye) corresponding to the captured images of the left and right virtual cameras CL and CR. Then, by outputting these in accordance with, for example, the parallax barrier method, the virtual space 100 including the objects 101 and 102 is stereoscopically displayed on the second display 15.

  In the case of FIG. 4, the front part 101 a located in front of the projection plane 103 in the rectangular object 101 is displayed so as to jump out from the screen of the second display 15. On the other hand, the rear portion 101b located far from the projection plane 103 and the spherical object 102 are displayed so as to be retracted and located in the back direction of the screen of the second display 15.

[Color phase setting processing]
Here, the game apparatus 1 performs a color appearance setting process in order to further enhance the stereoscopic effect. In this color appearance setting process, a predetermined reference surface 110 facing the virtual cameras CL and CR is set in the virtual space 100, and the proximity region 111 closer to the virtual cameras CL and CR than the reference surface 110 A different color appearance is set in the remote area 112 on the opposite side. Hereinafter, the color appearance setting process will be described in more detail.

  In the present embodiment, the control unit 30 sets the reference plane 110 so as to overlap the projection plane 103 in the virtual space 100. Therefore, in the example shown in FIG. 4, the rectangular object 101 is located across the reference plane 110, and the spherical object 102 is located far from the reference plane 110. In FIG. 4, the reference plane 110 is displayed with a slight shift with respect to the projection plane 103 in order to ensure visibility. Then, at least one of a process for increasing the attractiveness for an object located in the proximity area 111 in front of the reference plane 110 and a process for reducing the attractiveness for the remote area 112 far from the reference plane is performed. Run. That is, the color appearance setting process may include a process for increasing the attractiveness and a process for reducing the attractiveness. Here, the attention value is the degree to which a person's visual attention is attracted, and the higher the attractiveness, the stronger the visual attention of the person.

  Examples of the process for increasing the attractiveness include a process for increasing saturation, a process for increasing lightness, and a process for increasing luminance. Moreover, it is good also as performing several processes simultaneously among these. On the other hand, as processing to reduce attractiveness, for example, processing to lower saturation, processing to lower brightness, processing to lower brightness, processing to superimpose transparent colors, and superimpose fine patterns such as stitches And a process for making a monotone. Moreover, it is good also as performing several processes simultaneously among these.

  FIG. 5 is a schematic diagram of a stereoscopic image when a color appearance setting process is performed when the virtual space shown in FIG. 4 is stereoscopically displayed. Among these, (a) is a schematic diagram of a stereoscopic image when processing for increasing the saturation is performed on the surface of an object located in the close region 111, and (b) is a saturation for the remote region 112. It is a schematic diagram of a stereo image when the process which makes low is performed. For comparison, (c) shows a schematic diagram of a stereoscopic image when the color appearance setting process is not performed.

  A predetermined saturation (initial value) is set for each display frame on the surfaces of the objects 101 and 102. In other words, the saturation is affected by the surrounding environment (such as the illuminance of light and the presence or absence of elements that scatter light such as fog). The set value can change. For convenience of explanation, in the state shown in FIG. 4, for example, the initial value of saturation is set to 70% with respect to the entire surface of the rectangular object 101.

  First, a case where the stereoscopic image shown in FIG. 5A is generated will be described. As shown in FIG. 4, the front part 101 a of the rectangular object 101 is located in front of the reference plane 110. Therefore, the color appearance setting unit 30d performs a process of increasing the saturation of the surface of the front part 101a located in the proximity region 111 of the rectangular object 101. For example, since the initial value of the saturation of the entire surface of the rectangular object 101 is 70%, the saturation of the surface of the front part 101a is reset (updated) to 90% higher than that. As a result, as shown in FIG. 5A, the surface of the front portion 101a of the rectangular object 101 located in front of the reference plane 110 has improved attractiveness compared to other portions, and attracted the user's attention. To do. As a result, the user visually recognizes that the front part 101a of the rectangular object 101 protrudes further from the reference plane 110 (that is, the screen of the second display 15), and the stereoscopic effect is emphasized.

  Next, a case where the stereoscopic image shown in FIG. 5B is generated will be described. As shown in FIG. 4, the rear part 101 b and the spherical object 102 of the rectangular object 101 are located farther from the reference plane 110. Therefore, the color appearance setting unit 30d performs a process of lowering the saturation on the remote area 112 including the rear part 101b of the rectangular object 101 and the spherical object 102. For example, since the initial value of the saturation of the rectangular object 101 is 70%, the saturation of the surface of the rear part 101b is set to 40% lower than that. Similarly, for other objects existing in the remote area 112 and all other elements constituting the remote area 112, the saturation is reset (updated) so that it is lower than the individually set initial value. ) As a result, as shown in FIG. 5B, the attractiveness of the remote area 112 far from the reference plane 110 is lower than that of the front portion 101 a of the rectangular object 101 existing in front of the reference plane 110. In other words, the front part 101a of the rectangular object 101 is relatively more attractive than the other parts. As a result, the user visually recognizes that the front portion 101a of the rectangular object 101 protrudes further from the screen of the second display 15, and the stereoscopic effect is enhanced.

  FIG. 6 is a flowchart showing the processing contents when generating a stereoscopic image as shown in FIG. FIG. 6 illustrates a case where each frame constituting the moving image is generated for each frame, and such processing is performed by the virtual space generating unit 30b, the parallax image generating unit 30c, and the like included in the control unit 30. The color aspect setting means 30d performs the sharing.

  The control unit 30 first sets (updates) each element constituting the virtual space. That is, the setting of objects constituting the virtual space (step S10), the setting of light sources and virtual cameras (step S11), the setting of effects (step S12), and the like are performed. In the object setting (step S10), the position, shape, texture, etc. after the elapse of one frame are determined for an object modeled in advance using a polygon or the like. In the light source setting (step S11), the position, orientation, luminous intensity, etc. of the light source after one frame elapses are determined. In the virtual camera setting (step S11), the position, orientation, Determine the angle of view. In the effect setting (step S12), for example, the position, color, life and the like of each particle expressing sparks are determined, and the texture color and blend ratio expressing fog are determined.

  Next, the control unit 30 performs a rendering process for generating a two-dimensional image based on the virtual space set as described above. This processing is executed for each of the left-eye image and the right-eye image. When subdivided, solid processing (step S20), removal processing (step S21), transparency processing (step S22), effect processing (step S23), and screen processing are performed. (Step S24) and the like are included. Data generated by each process is sequentially written in a frame buffer prepared in the RAM 35 or the like.

  Each process included in the rendering process will be described. First, in the solid processing (step S20), two-dimensional frame data indicating an opaque object is generated and written into the frame buffer. In the extraction process (step S21), frame data indicating a planar object such as a leaf of a tree to be included in the frame image is generated and written into the frame buffer. In the transparency process (step S22), frame data indicating a transparent object is generated and written into the frame buffer.

  In the effect process (step S23), for example, frame data indicating particles such as sparks is generated and written to the frame buffer. Also, for example, the result of combining the fog texture with other frame data in accordance with the blend rate is written to the frame buffer. In the screen processing (step S24), a two-dimensional image (for example, a player character's physical strength gauge, a character string indicating the content of the character's remarks, etc.) displayed at a position closest to the virtual camera with respect to the objects constituting the virtual space is displayed. The frame data shown is generated and written to the frame buffer.

  In the flowchart shown in FIG. 6, for convenience of explanation, it is described that the processes are executed in the order shown in the figure, but actually, the processes are executed in different orders depending on the rendering method employed, In some cases, processing is executed simultaneously. Further, it is only necessary to execute necessary processes according to the state of the virtual space, and it is not necessary to execute all the processes.

  Saturation resetting in the hue setting processing can be realized by solid processing (step S20) included in the rendering processing. For example, in solid processing, the saturation (initial value) of each corresponding pixel is acquired from the texture data of each object as color information on the surface of the object. On the other hand, in the hidden surface erasing process for erasing a portion that does not require display from the positional relationship with another object, for example, the depth value (distance from the virtual camera) of each pixel is acquired by a known Z buffer method. Then, this depth value is compared with the reference plane, and it is determined whether the object to be displayed by each pixel is in front of or far from the reference plane.

  As a result, for the pixel corresponding to the object located in front of the reference plane, the saturation is updated to a value higher than the initial value. Thereby, frame data for displaying a stereoscopic image as illustrated in FIG. 5A can be generated. Alternatively, when it is determined that an object located far from the reference plane is to be displayed for a certain pixel, the saturation of the pixel may be updated to a value lower than the initial value. In this case, frame data for displaying a stereoscopic image as illustrated in FIG. 5B can be generated. Furthermore, both the above-described processes may be executed together.

  As described above, by setting different color appearances in the proximity area 111 and the remote area 112 with the reference plane 110 as a boundary, the stereoscopic effect of an object positioned in front of the reference plane 110 can be enhanced. it can.

  In the above-described embodiment, the case where saturation is set as the color aspect has been described in detail. However, the case where other aspect is set can also be realized in the same manner, and this is also positioned in front of the reference plane 110. The stereoscopic effect of the object can be enhanced. For example, when setting brightness and brightness, as in the case of saturation, the initial value of brightness and brightness for each pixel is obtained in solid processing, and based on the comparison result between the depth value of each pixel and the reference plane, What is necessary is just to reset the brightness and brightness | luminance of each pixel.

  Further, when the color appearance is changed by the process of superimposing the transparent color, the initial value of the color information (hue, saturation, brightness, luminance, etc.) for each pixel is acquired in the same manner as described above. Then, based on the comparison result between the depth value and the reference value, it is only necessary to reset (update) the color information in which the transparent color is superimposed on the pixel displaying the object located far from the reference surface. In the process of superimposing the transmissive color, a transmissive color filter may be used. In this case, the filter is arranged in parallel to the reference plane at or near the reference plane. Then, image data may be generated by photographing the virtual space through the filter with a virtual camera. As such a transparent color filter, for example, a translucent planar two-dimensional object (so-called “writing split”) can be used.

  Alternatively, an arbitrary color may be blended at a predetermined rate with respect to the color information of the pixel. Furthermore, by changing the blend rate in accordance with the depth value of the object to be displayed in each pixel, fog may be superimposed farther from the reference plane, thereby reducing the attractiveness of the remote area. The monotoning process is basically the same, and the pixel color for displaying an object located far from the reference plane is reset to gray or dark display with an achromatic color or brown color according to the initial color information ( Update).

  Note that the target for producing a stereoscopic effect is not limited to a three-dimensional object. For example, by placing a character, symbol, or two-dimensional image in front of the reference plane, and making these colors different from each other in the remote area, the character, symbol, or two-dimensional image can be made even more in front of the screen. It can be displayed so as to pop out and be positioned. Further, the position of the reference plane is not limited to the aspect matching the projection plane, and may be positioned away from the projection plane or far away.

  The present invention can be applied to a computer program and a computer system that generate a pair of virtual two-dimensional images having parallax for stereoscopic display of a virtual object on a display unit.
