[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus for generating an image, and more particularly to an information processing apparatus for generating an image at high speed.

[0002]

2. Description of the Related Art Conventionally, an image is generated at high speed by utilizing a human visual recognition action to generate a high-definition image only in a gaze area and a non-high-definition image in other non-gaze areas. There is. For example, JP-A-4-30238
In the technique described in Japanese Patent Publication No. 1, in image generation in computer graphics, dedicated hardware such as an eye position detecting device and a head posture detecting device is used as a gazing point detecting device, and observation is made from data obtained therefrom. The gaze direction of the person is calculated, and the gazing point on the monitor is calculated. In order to differentiate the information amount of the generated image between the gaze area and the non-gaze area, a method of changing the definition of the image depending on the area is used.

Further, there is a technique in which the gazing area is set to a fixed area in the screen, specifically, to the central portion of the screen, and the definition of the generated image is changed between the gazing area and the non-gazing area. It is described in JP-A-3-233781.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The technique disclosed in Japanese Patent No. 1 has the following two problems.

First, as a method of knowing the gazing area, dedicated hardware such as an eyeball position detecting device must be used.

Further, as a method of rapidly generating an image of the non-gaze area, only a method of changing the definition is mentioned.
Therefore, the present invention cannot be used in an apparatus in which the definition cannot be changed in image generation. Further, even in a device capable of changing the definition, when higher-speed image generation is required, the only option is to further reduce the definition of image generation.

The technique disclosed in Japanese Patent Application Laid-Open No. 3-233781 is
The gaze area cannot be changed on the screen. Also, similar to the above, if a faster image generation is needed,
There is also a problem that the only option is to further reduce the definition of image generation.

One of the objects of the present invention is to provide an information processing apparatus capable of determining a gaze area without using dedicated hardware.

Another object of the present invention is to provide an information processing apparatus using a method other than changing the definition as a method of differentiating the information amount of image data generated between a gaze area and a non-gaze area. Is.

Image source data storing image source data that is source data when generating image data to be displayed in order to determine a gaze area without using dedicated hardware. A storage device, an image generation device that generates image data based on the image original data, an image data storage device that stores the generated image data, and an image display device that reads and outputs the image data, In an information processing device having a display screen and a display means for displaying the read image data on the display screen, a reception means for receiving an instruction to scroll the image data displayed on the display screen. The image data generating means has a scrolling method from the center of the display screen according to the instruction when generating the image data based on the image original data. Assuming that the user is paying attention to a predetermined area deviated to the opposite direction, the area has a large amount of information compared with the image data displayed in the area other than the above-mentioned area. As described above, the image data displayed in the gaze area is generated, and the area other than the gaze area is a non-gaze area that is not observed and less information compared with the image data displayed in the gaze area. It has an image data generation means for generating image data so as to have a certain amount.

Further, when a receiving means for receiving designation of a certain place or a certain area on the screen is provided or newly provided, it is considered that the user is paying attention to the surrounding area, and designation of a position or the like is performed. Is input, and the surrounding area is set as the gaze area.

Further, attribute storage means for storing information indicating whether or not the target is expected to be noticed is provided,
When the target is displayed on the screen, the user thinks that the target is to be focused, and the area around the target is set as the gaze area.

Further, since none of the above applies, when the gaze area is not determined, the user thinks that he is looking at the center of the normal screen, and sets the center of the screen as the gaze area. It is necessary to determine the display area and detect the center of the screen when generating the image data from the image original data, but this position can be easily determined from the image original data.

Next, in order to speed up image generation, the above-mentioned image data generating means adopts the following method as a method of differentiating the amount of information contained in the generated image data depending on whether it is a gaze area or not.

One is the number of lightness gradations (for example, 256
It changes between the gaze area and the non-gaze area.

Alternatively, when the image is a color image, the number of display colors is changed between the gazing area and the non-gazing area (for example, from 16 million colors to 4096 colors).

Alternatively, the precision of the calculation used in the image generation program is changed between the gazing area and the non-gazing area (for example, from double-precision arithmetic to single-precision arithmetic).

Alternatively, the parameter for controlling the image quality in the image generation algorithm (for example, the number of ray tracing rays tracing) is changed between the gazing area and the non-gazing area.

Alternatively, when the images are changing with time, such as when there is a moving object, the number of images generated within a certain period of time (for example, while the gazing area is performing image generation three times, The gaze area is changed between the gaze area and the non-gaze area such that the image is generated only once.

[0020]

With the above configuration, when the entire screen is scrolling in a certain direction, it is assumed that a person pays attention to the direction opposite to the scrolling direction, and the gaze area is moved from the center of the screen to the opposite side of the scrolling. It can be set at a shifted position. The scroll direction can be easily determined from the user's instruction or the image original data when the image original data includes scroll information.

The gaze area can be easily determined by the other means described above, and the gaze area can be predicted without using dedicated hardware according to the present invention.

Further, according to the present invention, a method other than changing the definition can be presented as a method of differentiating the amount of information contained in the image data between the gaze area and the non-gaze area. Therefore, the definition cannot be changed. High-speed image generation is possible even in the device.

EXAMPLE As an example of the present invention, an example of a CAD system for building design support using the present invention for image generation will be shown.
FIG. 1 is a block diagram of the embodiment. The present system includes a display 11, a computer 12, and a mouse 13 that is a receiving unit that receives designation of a place or area on the screen.
And a keyboard 14 which is a reception means for accepting an instruction for the user to move forward, backward, turn to the right, turn to the left, etc., and consequently receive a scroll instruction. The computer 12 further includes an image source data storage device 15, which is a unit for storing the image source data, and an attribute storage unit for storing information indicating whether or not the display target is predicted to be noticed, It has a data storage device 16, an arithmetic device 17 which is an image generation device, and an image display device 18. The arithmetic unit 17 has the functions of an image data generating means, a direction determining means, and a target object determining means. In the image source data storage device 15, building data is stored in advance as an aggregate of a plurality of planes. As the data of each plane, the three-dimensional coordinate data of the vertex, the color of the plane, the reflectance of light, the scattering rate of light, and the like are stored. For example, a cube is stored as an aggregate of 6 square planes, and 3 of the vertices of each plane are stored.
The position, size, and orientation of the cube are determined by the dimensional coordinate position data. Further, the image source data storage device 15 can store any number of light sources as data at any position in the space. The three-dimensional coordinate position, brightness, and color of the light source are stored as numerical values. Arithmetic unit 17
Based on that, the landscape from any point in the building is calculated and image data is generated in the image data storage device 16, which is displayed on the display 11 by the image display device 18. The landscape data generated in the image data storage device 16 is obtained by dividing the image into two-dimensional grids and digitizing the brightness and color data of each divided area. The arithmetic unit 17 gives the image original data and the position of the viewpoint as inputs, and finally any divided area of the image (for convenience, the divided area is calculated as a point).
When the light crosses the plane that is stored in the image source data storage device 15 every time the light that reaches the plane is traced in the opposite direction, the color of the crossed plane, the reflectance of the light, and the scattering rate of the light determine the Calculate how the direction of travel, color, and brightness have changed.
This calculation is performed until the backward tracking of the light reaches the light source or the light is attenuated below a preset value.
When light is traced in the opposite direction, the color and brightness of the light source are finally obtained from the color and brightness of the light source and the change of the light until reaching the light source. When the light is attenuated, it is considered that the light from that direction does not affect the image information. By performing the above calculation for all the divided areas on the image, the arithmetic unit 1
7 generates an image from the image original data stored in the image original data storage device 15, and the image data storage device 16
Can be transferred to. With this system, it is possible to virtually walk through the building at the design stage. Further, the movement information of the mouse 13 is transmitted to the arithmetic unit 17, and the arithmetic unit 17 can calculate the position of the mouse cursor 19 based on the movement information and can point to an arbitrary point displayed on the display 11, so that the virtual state is displayed. In the building, it is possible to reproduce an operation such as pressing a switch for lighting. The keyboard 14 is for instructing movement within the building. When a predetermined key on the keyboard 14 is input, it is transmitted to the arithmetic unit 17, and the arithmetic unit 17 calculates a virtual movement in a virtual building based on it and reflects it in the generated image data, Finally, it is displayed on the display 11. Instructions for movement, such as moving forward, moving backward, facing right, facing left 4
You can choose from one. The mouse cursor 19 indicates the position where the mouse is currently pointing, and the keyboard 14
With, it is possible to select display or non-display arbitrarily. An area surrounded by a dotted line in the image displayed on the display 11 is a gaze area 110. Other areas on the screen are non-gaze areas. In this embodiment, the present invention is used to speed up image generation when rewriting screen information in real time, such as when moving inside a building or when turning on a lighting switch.

FIG. 2 is a flowchart showing a program executed by the computer 12, in which only a portion for predicting a gaze area is extracted. After the gaze area is decided by the flow of this figure,
Image generation is performed in the flow of FIG. 3 described later. First, when the operation to turn to the right is input from the keyboard 14,
The entire screen scrolls to the left, and the screen computing device 17 determines that the user is mainly looking at the right side of the screen, and sets the gaze area on the right side of the screen (step 21, step 2).
5). Even when the operation is directed to the left, the left and right are reversed, and the same is true (steps 22 and 26). As an application of screen scrolling, for example, the gazing area may be set to the upper side of the screen when climbing the stairs and to the lower side of the screen when descending the stairs. Next, it is checked whether or not the mouse cursor 19 is displayed. If the mouse cursor 19 is displayed, it is considered that the user is mainly looking around the mouse cursor 17, and the user is set to the gaze area (step 23, step 27). ). When there is an instruction to hide the mouse cursor from the keyboard 14, all the objects displayed on the screen are checked for attributes indicating whether or not the objects are predicted to be noticed,
If there is an object that is predicted to be noticed when creating data (such as a sculpture in the case of a building, or an enemy airplane or the like in the case of a display related to a game), set the area around that object as the gaze area. (Step 24, Step 28).
The attributes are stored in the image source data storage device 15,
If the object is predicted to be noticed, the flag is set. If none of the above apply, there is no particular element of interest and the user thinks that he is looking at the center of the screen, and sets the gaze area to the center of the screen. The case corresponding to this is the case where no operation is input by the user (step 29). In this way, this system predicts the gaze area without using special hardware such as a gaze point detection device.

FIG. 3 is a flow chart showing a program executed by the computer 12, in which only a portion for generating an image is extracted. After the gaze area is determined in the flow of FIG. 2, the flow of this figure is executed. First, it is checked whether or not there is an operation of rewriting the screen such as movement (step 31), and if there is an operation of rewriting the screen, the gaze area generates image data having a relatively large amount of information. The image data is generated by an image generation program that generates image data having a relatively small amount of information in the non-gaze area by the program. (Step 33, step 34). Here, the operation of rewriting the screen refers to a situation such as a scrolling operation of the user and a situation in which something having a motion such as moving the elevator is displayed. The image generation programs for the gaze area and the non-gaze area are differentiated as described in Table 1 below. The image generation program for the gaze area has a relatively low execution speed, but the image for the non-gaze area is A program that generates image data having a relatively large amount of information as compared with the generation program is used.

[0026]

[Table 1]

Table 1 is a list of methods for differentiating the information amount of the images of the gaze area and the non-gaze area in image generation. Six methods are listed, including a method of changing the definition of a known example.

As the image generation program for the non-gaze region, an information generation amount of the generated image data is relatively small, but an image generation program for generating a relatively high speed is used as compared with the image generation program for the non-gaze region. To do. If there is no operation to rewrite the screen, an image generation program that generates image data with a large amount of information equivalent to the gaze area is generated from the image data generated with a relatively small amount of information in the previous rewriting. Rewrite (step 32,
Step 35). A method of separately generating the gaze area and the non-gaze area at the time of image generation will be described later with reference to FIG.

FIG. 4 shows the display 1 when virtually walking through a building using this system.
It is an example of the screen displayed in 1. The dotted line in the figure (the size of the area enclosed by the dotted line is determined according to the purpose of use) is
This indicates that the area surrounded there is a gazing area, and the dotted line itself is not actually displayed on the screen. It should be noted that in the embodiment, the gazing area is a rectangular area for the sake of convenience, but in reality, a circular area, an elliptical area (ideally an elliptical shape because there are two eyes of the user), and various other shapes are conceivable. To be

The screen 41 is a screen when moving forward on a passage in a building. There is no scrolling up / down / left / right of the screen, and the mouse cursor is hidden. Further, since there is no particular object on the screen, the gazing area is in the center of the screen.

The screen 42 is a screen when the operation of turning to the right is performed because the passage turns right while the vehicle is moving forward.
Since the entire screen scrolls to the left, the gaze area is to the right of the screen.

The screen 43 shows a lighting switch 432 for turning on the lighting 431 while advancing through the passage in the building.
This is the screen when the mouse cursor 433 is displayed to press. The area around the mouse cursor 433 is the gaze area.

The screen 44 is a screen when an object (sculpture 441 in this example) predicted to be noticed in advance is encountered when creating data of a building while advancing through a passage in the building. Since the engraving 441 has an attribute of being noticed when creating building data, the surrounding area becomes the gazing area.

Next, of the methods shown in Table 1 above, five methods other than changing the definition will be described.

The method of changing the number of lightness gradations is a method of changing the number of lightness gradations when calculating the lightness on the screen in an apparatus for producing a monochrome image. In general,
When the image is generated by dividing the lightness into fine gradations, image data having a larger amount of information can be generated, but it takes time to generate the image. For example, in the case of an apparatus in which the brightness of a normal image is 256 gradations, the image generation in the gazing area remains 256 gradations, and the image in the non-gaze area is reduced to 16 gradations to generate the total calculation amount. And the image generation time can be shortened. Note that when this method is used, image data having different lightness gradations must be converted into the same data format. For that purpose, the brightness gradation of the image data having a relatively small number of brightness gradations is corrected according to the brightness gradation of the image data having a relatively large number of brightness gradations. Various methods can be considered for the correction, but the simplest method is the method of Equation 1. The number 1 will be explained in detail later.

The method of changing the number of display colors is a method of changing the number of colors when calculating the colors on the screen in the apparatus for generating a color image. Generally, if the number of display colors is finely divided and an image is generated, image data having a larger amount of information can be generated, but it takes time to generate the image. For example, a normal image has 16 million colors (red, blue, green, 25 for each
In the case of a device with 6 gradations, the calculation of image generation of the gaze area is 1
To reduce the total calculation amount and shorten the image generation time by reducing the number of images in the non-gaze area to 4096 colors (16 gradations for each of red, blue and green) while maintaining 6 million colors You can Note that when this method is used, image data having different numbers of colors must be treated as one image data, as in the method of changing the brightness gradation.
For that purpose, the color of the image data having a relatively small number of colors is corrected according to the color of the image data having a relatively large number of lightness gradations. Although various methods can be considered for the correction, the simplest method is to divide the color into three primary colors of red, blue, and green, and use the correction method described in Equation 1 for the brightness of each primary color. The number 1 will be explained in detail later.

The method of changing the accuracy of the calculation used in the image generation program is as follows.
This is a method of changing the precision of calculations used in programs such as brightness calculation and color calculation. In general, the higher the accuracy of the calculation used in image generation, the more image data can be generated, but it takes time to generate the image. For example, if the precision of the numerical value used in the internal calculation of normal image generation is 16 digits, the calculation precision of the image generation of the non-gaze area is set to 9 digits, thereby reducing the overall calculation amount and shortening the image generation time. can do.

The method of changing the parameter that controls the quality of the image generation algorithm is as follows. When the image generation algorithm used for image generation has parameters controlling the image information amount and generation speed This is a method of changing the value of the parameter when generating. For example, when ray tracing is used as an image generation algorithm, the image data having a larger amount of information can be generated as the number of ray traces increases, but the image generation takes time. The image generation time can be shortened by setting the number of ray tracings to be large in the gaze area and small in the non-gaze area.

As a method of reducing the number of image generations within a certain time, for example, the image generation is performed only once in the non-gaze region while the gaze region performs screen generation three times. Alternatively, it is a method of thinning out the number of times of image generation of the non-gaze region within a fixed time, such as performing image generation of the gaze region 24 times per second, while performing image generation of the non-gaze region only 6 times. This method reduces the amount of image data to be transferred to the image storage device of the display, not only when the image is calculated each time the image is generated, but also when the image data that is calculated in advance is used for image generation. Therefore, the image generation time can be shortened.

In practice, not all of the methods listed here are applied, but at the time of designing a device using the present invention, it is necessary to consider the orientation of the object to be imaged, the image generation algorithm, etc. A method (or a combination of a plurality of methods) that can obtain speed and is considered not to subjectively deteriorate the image quality when viewed by the user is selected and applied.

FIG. 5 shows another embodiment of the present invention in which a part of the image original data having a size that cannot be displayed on the screen is displayed and edited by the drawing software. Is. This device comprises an image source data storage device 51, a calculation control device 52, a display image storage device 53, a keyboard 54, and a display 55. The arithmetic and control unit 52 transfers the image data of the area designated by the keyboard 54 from the image source data storage unit 51 to the display image storage unit 53. In this example, since the image source data stored in the image source data storage device 51 has already been calculated, the method of changing the definition of Table 1, the method of changing the number of lightness gradations, the method of changing the number of display colors, the image The method of changing the precision of the calculation used in the generation program and the method of changing the parameter controlling the quality of the image generation algorithm are ineffective. In this embodiment, when the image data display area is scrolled by an instruction from the keyboard 54,
The opposite side of the scroll is set as the gaze area, and the image is transferred within a certain period of time (the CPU of the arithmetic and control unit 52 has a mo
By using the method of reducing the number of times of (transfer by pixel unit by ve command), the information amount of the image data transferred from the image source data storage device 51 to the display image storage device 53 is reduced, and high-speed scrolling is realized. You can also transfer a part of it from the original image data as image data,
This case is also one of the embodiments of the present invention because it can be considered as a method of image generation.

FIG. 6 shows one of the implementation methods when an image is generated by dividing the gaze area and the non-gaze area. The image data is divided into image division 61 to image division 69. Here, the image section 61 is a gaze area, and the image sections 62 to 69 are non-gaze areas. When an image of a rectangular area having an arbitrary position and size can be generated, image data of a portion corresponding to the image section 61 is generated from the image original data so as to have a relatively large amount of information, and further, From the image original data, the image data of each portion corresponding to the image division 62 to the image division 69 is generated so as to have a relatively small amount of information. The generated image data of each part is finally transferred to one image data storage device and completed as one image data. Depending on the position of the gaze area, that is, the image segment 61, the image segments 62 to 6
It is possible that some of the areas of 9 will be zero.

Formula 1 is an equation for correcting the brightness gradation. Let P be the number of lightness gradations of image data having a relatively large number of lightness gradations, and Q be the number of lightness gradations of image data having a relatively small number of lightness gradations. At this time, if the brightest brightness and the darkest brightness represented by both brightness gradations are equal, the brightness gradation data X before correction (X is an integer from 0 to Q-1) The gradation data Z (Z is an integer from 0 to P-1) is obtained as follows.

[0044]

## EQU00001 ## Z = X.times. (P ÷ Q) Actually, P ÷ Q is a constant, and since P and Q are often n to the power of 2, the equation 1 is a bit shift. It can often be achieved only by itself.

[0045]

According to the present invention, the gaze area can be determined without using dedicated hardware, and the image generation method is changed depending on whether the gaze area is the gaze area. Therefore, the speed of image generation is increased. be able to.

Further, since there are a plurality of methods for changing the amount of information contained in the generated image data at the time of image generation, it is possible to obtain a device for generating an image at a higher speed by properly using or combining them. You can
