Description

  The present invention relates to a display device, a display method, and a program for realizing these by a computer, which are suitable for presenting the degree of change in the position of interest to a user in an easy-to-understand manner.

  A shooting game in which a user shoots a target in a virtual space displayed on a monitor is known. A game device that controls such a shooting game displays a state image representing a state of viewing a virtual space in which a plurality of objects are arranged on a monitor. On the other hand, the user operates a simulated gun or a controller connected to the game device, inputs an instruction to aim at the target represented in the state image, and then inputs an instruction to fire a bullet do. In such a shooting game, there is a function of enlarging the state represented by the state image around the aiming position and displaying on the monitor a detailed image cut out to a predetermined size around the aiming position. There is something to prepare.

  Such a detailed image may be displayed on the monitor independently of the state image, or may be displayed on the monitor superimposed on the state image. In either case, a detailed image needs to be displayed so that the user can appropriately grasp information necessary for shooting. For example, Patent Literature 1 discloses a game system that can appropriately display detailed images so that a user can appropriately grasp information necessary for shooting.

Japanese Patent No. 3345600

  However, in the game system disclosed in Patent Document 1, the user cannot immediately determine whether or not the aim is determined based on the image displayed on the monitor. For this reason, in a shooting game, there is a strong desire to know the degree of change in the position of the aim. In addition, there is a demand for knowing the details of the state around the position of interest in the image.

  The present invention has been made in view of the above-described problems, and is a display device suitable for presenting the degree of change of a position focused by a user in an easy-to-understand manner, a display method, and a program for realizing these by a computer The purpose is to provide.

  In order to achieve the above object, a display device according to a first aspect of the present invention includes a state generation unit, a display unit, and a reception unit, and is configured as follows.

  First, the state generation unit generates a state image representing a state of viewing a virtual space where a plurality of objects are arranged. This virtual space may be a three-dimensional virtual space or a two-dimensional virtual space. Then, the display unit displays the state image generated by the state generation unit.

  The accepting unit accepts an instruction input for designating a target position in the state image displayed on the display unit. The reception unit may be configured by a controller including an acceleration sensor and an angular velocity sensor. In this case, the user designates the target position by adjusting the angle of the controller. Here, for example, in the shooting game, the position to be aimed can be set as the target position. In this case, the instruction input is an operation of the controller that designates a position for aiming, which is made by the user.

  On the other hand, when the degree of change of the attention position is equal to or less than a predetermined threshold, the display unit displays the first instruction image so as to overlap the attention position of the state image. Note that the degree of change of the target position may be defined in any way as long as it represents the degree of change of the target position. For example, the speed of movement of the attention position or the size of the movement range of the attention position can be set as the degree of change of the attention position. Hereinafter, the operation of the display unit when the present invention is applied to a shooting game will be described with specific examples. Here, a case will be described in which the moving speed of the target position is set as the degree of change of the target position. First, the display unit determines whether or not the attention position designated by the instruction input has changed significantly. For example, the display unit samples the position of the aim on the screen determined by the user operating a simulated gun or a controller at a predetermined sampling period. Here, for each sampling, the display unit obtains the moving speed of the aiming position by dividing the distance between the aiming position sampled last time and the aiming position sampled this time by the sampling period. And a display part calculates | requires the average value in the predetermined period of the speed which the position of an aim moves, and determines whether the said average value is below a predetermined threshold value. And a display part displays a 1st instruction | indication image, when it determines with the said average value being below a predetermined threshold value, ie, when it determines with the attention position not changing largely. Here, the first instruction image is displayed so as to be superimposed on the target position of the state image. For example, an image indicating that the aim is fixed (typically, an image indicating the aim) can be used as the first instruction image. Accordingly, the user can determine that the aim is determined when the first instruction image is displayed.

  According to the display device of the present invention, it is possible to present the degree of change of the position focused by the user in an easily understandable manner.

In the display device of the present invention, the display unit can be configured as follows. That is, the display unit displays the second instruction image so as to overlap the attention position of the state image when the degree of change of the attention position exceeds a predetermined threshold. For example, in a shooting game, when the display unit determines that the average value of the moving speed of the aiming position in a predetermined period exceeds a predetermined threshold, an image indicating that the aim is not determined (typically, An image representing a mark other than the aim) can be displayed as the second instruction image so as to overlap the target position of the state image. As a result, the user can determine that the aim is not determined when the second instruction image is displayed.
According to the display device of the present invention, it is possible to present the degree of change of the position focused by the user in an easily understandable manner.

  The display device of the present invention may further include a detail generation unit shown below. That is, the detail generation unit generates a detail image having a predetermined size smaller than the state image when the degree of change in the target position is equal to or less than a predetermined threshold. This detailed image is an image obtained by enlarging the state represented by the state image around the position of interest and cutting it out to a predetermined size around the position of interest. That is, the detailed image is an image that is displayed on the magnifying glass when the attention position in the state image is viewed with the magnifying glass. Here, when the detailed image is generated, the display unit sets the detailed image as the first instruction image. That is, the display unit displays the detailed image as the first instruction image when the degree of change in the target position is equal to or less than a predetermined threshold value.

When the present invention is applied to a shooting game, for example, when it is determined that the aim is determined, a detailed image representing a region where the aim is in the virtual space is displayed in detail. Therefore, the user can aim accurately with reference to the detailed image.
According to the display device of the present invention, it is possible to present the degree of change of the position focused by the user in an easily understandable manner. Further, according to the display device of the present invention, it is possible to present a detailed image that represents in detail the state represented at the position of interest in the state image. Therefore, according to the display device of the present invention, the user can specify the position of interest more accurately.

In the display device of the present invention, the virtual space can be a desktop space in which a plurality of windows or icons are arranged. That is, the present invention can be applied to a display device that displays a state image representing a two-dimensional desktop space. According to such a configuration, even if there is no operation such as changing the resolution of the screen, an image showing in detail a portion on which the user pays attention is displayed.
According to the display device of the present invention, it is possible to present an image showing in detail the portion of interest on the desktop by the user.

In the display device of the present invention, the virtual space can be a three-dimensional space in which a plurality of objects are arranged. In this case, the state image is an image representing a state viewed from the first viewpoint arranged in the virtual space. Further, the detailed image is an image representing a state in which the virtual space is viewed from the second viewpoint approaching the object drawn at the position of interest in the state image from the first viewpoint in the virtual space. According to this configuration, an image that represents in detail the object drawn at the position of interest in the state image can be a detailed image. That is, the detailed image is an image that represents in detail the state represented at the position of interest in the state image, but can be an image that is newly generated with reference to the second viewpoint. Thus, the detailed image newly generated based on the second viewpoint is a detailed image generated based on the state image (for example, an image obtained by enlarging the state image and cutting it out to a predetermined size). Compared to (), the image shown in the attention position in the state image is clearly displayed.
According to the display device of the present invention, it is possible to present a detailed image representing in detail the state represented at the target position in the state image.

In the display device of the present invention, the distance from the first viewpoint to the second viewpoint (hereinafter referred to as “first distance”) is the distance from the first viewpoint to the object drawn at the target position. (Hereinafter, referred to as “second distance”). As described above, the state image is an image representing a state where the object drawn at the target position is viewed from the first viewpoint, and the detailed image is the second viewpoint approaching the object from the first viewpoint. From the above, it is an image showing a state of viewing the object. In other words, the detailed image is an image representing the state represented by the state image in an enlarged manner, but the enlargement ratio depends on the ratio between the first distance and the second distance. Therefore, a desired enlargement ratio can be obtained by appropriately adjusting the ratio between the first distance and the second distance. For example, the enlargement ratio can be made constant by setting the first distance to a length proportional to the second distance. That is, in order to increase the magnification ratio by K, the second distance is set to K / (K-1) times the first distance. Further, for example, by setting the first distance to a length obtained by subtracting a certain length from the second distance, an image representing a state in which the object is viewed from a position away from the object by a certain distance is displayed as a detailed image. It can be. That is, in order to make a detailed image an image showing a state where the object is viewed from a position away from the object by D, the position of the second viewpoint is separated from the object by D regardless of the position of the first viewpoint. Position. At this time, the magnification rate increases as the object is located farther away, and the magnification rate decreases as the object is aimed closer. According to these configurations, an image representing in detail the object drawn at the position of interest in the state image can be a detailed image. In addition, it is possible to specify how much a magnification image of the state represented by the state image is used as the detailed image.
According to the display device of the present invention, it is possible to present a detailed image representing in detail the state represented at the target position in the state image.

In the display device of the present invention, the size of the detailed image can be set in advance to correspond to the degree of change in the target position. For example, when the present invention is applied to a shooting game, the smaller the degree of change in the position of interest, the larger the detailed image. That is, when the aim is determined in the shooting game (when the degree of change in the position of interest is small), it is desired to display a detailed image with a larger angle of view in order to accurately determine the aim. In the shooting game, the smaller the average value of the moving speed of the aiming position (or the absolute value of the acceleration at which the aiming position moves) in a predetermined period, the larger the detailed image may be. However, the detailed image may be enlarged as the moving range of the aiming position in the predetermined period is smaller.
According to the display device of the present invention, according to the degree of change of the target position designated by the instruction input, the size of the detailed image that represents in detail the state represented by the target position in the state image is changed. The detailed image can be presented.

In the display device of the present invention, the degree of change of the target position can be an average value of the moving speed of the target position in the recent predetermined period. For example, in a shooting game, based on the aim position for the past 2 seconds sampled at each screen update period, an average value of the moving speed of the aim position in the 2 seconds is calculated, and the calculated average value is calculated. The degree of change in the position of interest. In this way, a value based on the moving speed of the target position can be set as the degree of change of the target position. In this case, for example, the larger the average value of the moving speed of the target position in the recent predetermined period, the greater the degree of change of the target position. For example, in a shooting game, when the average value of the moving speed of the aiming position in a recent predetermined period is equal to or less than a predetermined threshold, it is determined that the aim is determined, and the first instruction image is a state image. It is displayed superimposed on the position of the aim. On the other hand, when the first instruction image is displayed, the user can determine that the aim is fixed and execute the shooting.
According to the display device of the present invention, it is possible to present the degree of change of the position focused by the user in an easily understandable manner.

Further, in the display device of the present invention, the degree of change of the attention position can be set to the size of the movement range of the attention position in the recent predetermined period. For example, in a shooting game, based on the aiming position for the past 2 seconds sampled at each screen update cycle, the size of the moving range of the aiming position in the 2 seconds is obtained, and the size of the obtained moving range is calculated. The degree of change in the position of interest. Thus, a value based on the size of the moving range of the target position can be set as the degree of change of the target position. In this case, for example, the larger the moving range of the attention position in the recent predetermined period, the greater the degree of change in the attention position. For example, in a shooting game, when the size of the movement range of the aim position in the recent predetermined period is equal to or less than a predetermined threshold, it is determined that the aim is determined, and the first instruction image is aimed at the state image. Overlaid at the position of. On the other hand, when the first instruction image is displayed, the user can determine that the aim is fixed and execute the shooting.
According to the display device of the present invention, it is possible to present the degree of change of the position focused by the user in an easily understandable manner.

In the display device of the present invention, the reception unit may be configured as follows, and further include a moving unit as described below. That is, the accepting unit further accepts an instruction input designating that a predetermined movable object is to be moved. Note that the predetermined movable object is a first viewpoint (a viewpoint in which a state represented by the state image is viewed and is disposed in the virtual space) among a plurality of objects disposed in the virtual space. The object is arranged at the movement start position where the relative position of is fixed. Further, when an instruction input designating that movement is to be performed is received, the moving unit moves the movable object as shown below. That is, the moving unit moves the movable object from the movement start position to the object drawn at the target position as time passes. For example, when the present invention is applied to a shooting game, a bullet can be handled as a movable object. In this case, the movement unit moves the bullet from the movement start position to the position indicated by the aim with the passage of time when an instruction input for instructing to fire the bullet is received by the reception unit. Here, if it is determined that the aim is determined, the first instruction image is displayed at the expected arrival position of the bullet. On the other hand, the user inputs an instruction to fire a bullet when the first instruction image is displayed. When the instruction input is accepted, the bullet moves from the movement start position to the position indicated by the aim with time.
According to the display device of the present invention, the destination of the movable object can be appropriately presented.

  The CPU 101 controls the overall operation of the information processing apparatus 100 and is connected to each component to exchange control signals and data. The CPU 101 acquires various types of data from each component, processes the various types of data by various calculations, and provides the data to each component as data and control signals. In the CPU 101, various types of data are temporarily stored in a cache included in the CPU 101, and are further acquired in a register included in the CPU 101, and then various calculations are performed.

The ROM 102 stores an IPL (Initial Program Loader) that is executed immediately after the power is turned on, and when this is executed, the program recorded on the DVD-ROM is read out to the RAM 103 and execution by the CPU 101 is started. The
The ROM 102 stores an operating system program and various data necessary for operation control of the entire information processing apparatus 100.

  The RAM 103 is for temporarily storing data and programs, and holds programs and data read from the DVD-ROM and other data necessary for game progress and communication. In addition, various information transmitted from various devices connected to the information processing apparatus 100 and various information to be transmitted to various devices are also temporarily stored.

  The controller unit 105 connected via the interface 104 receives an operation input performed when the user executes the game. Hereinafter, the controller unit 105 will be described with reference to FIG. FIG. 2 is an external view for explaining an outline of the controller unit 105.

  The controller unit 105 includes a controller 210 and a sensor bar 220 as shown in FIG. The information processing apparatus 100 is connected to the sensor bar 220 and the display 290 via predetermined cables.

The controller 210 has an appearance similar to a remote control such as a television, for example, and is connected to the information processing apparatus 100 wirelessly (by wireless communication). The user holds the controller 210 with one hand and plays the game. In the information processing apparatus 100, holding the controller 210 with the right hand is determined as a correct (standard) way of holding.
The sensor bar 220 is formed in a bar shape having a predetermined length, and is appropriately fixed on the top of the display 290 along the direction of the screen. In the sensor bar 220, one light emitting element 221 is embedded at each end. Note that the number of light emitting elements 221 to be embedded is an example, and may be larger than these numbers.
The sensor bar 220 receives power from the information processing apparatus 100 and causes the light emitting element 221 to appropriately emit light.

When the CCD camera 211 is arranged at the tip and the tip is directed to the display 290, the controller 210 captures an image including the two light emitting elements 221 (two light emitting points) of the sensor bar 220. In addition, the controller 210 includes a wireless communication unit therein, and sequentially transmits information of captured images to the information processing apparatus 100 by wireless communication.
Then, the information processing apparatus 100 appropriately acquires the position and orientation of the controller 210 based on the positional relationship between the two light emitting points in the image sent from the controller 210. For example, the CPU 101, the image processing unit 107, and the like analyze the positional relationship between two light emitting points visible from the controller 210, calculate the spatial position of the controller 210 and the direction of the tip (the direction of the longitudinal axis), Finally, it is obtained where the user is operating the controller 210 on the screen.

The display device 300 is a device that presents a screen during execution of the shooting game to the user. Specifically, the display device 300 presents a screen as shown in FIGS. 4A and 4B. 4A and 4B show a state in which a plurality of target objects 401 are arranged in a virtual space. In this shooting game, the user inputs an instruction for aiming at the target object 401, and when it is determined that the position of the aim has overlapped with the position of the target object 401, the bullet object 408 is fired toward the target object 401. Input instructions to make it happen. In the present embodiment, the second instruction image 403 shown in FIG. 4A is displayed while the aim is not determined, and the first instruction image 404 shown in FIG. 4B is displayed when the aim is determined. In the present embodiment, it is assumed that the aiming position is a position that the user is paying attention to (hereinafter referred to as “attention position”). 4A and 4B, the position (coordinates) indicated by the black dot 402 is the target position. FIG. 4B shows a state in which the bullet object 408 is fired.

  As illustrated in FIG. 3, the display device 300 according to the present embodiment includes a state generation unit 301, a display unit 302, a reception unit 303, a detail generation unit 304, a movement unit 305, and second instruction image generation. Unit 306 and a storage unit 307.

  The state generation unit 301 generates a state image 410 representing a state in which a virtual space where a plurality of objects such as the target object 401 and the bullet object 408 are arranged is viewed. Specifically, the appearance generation unit 301 generates the appearance image 410 based on virtual space information stored in the storage unit 307 described later. In the present embodiment, this virtual space is a three-dimensional virtual space in which a plurality of objects such as the target object 401 and the bullet object 408 are arranged. The state image 410 is an image representing a state viewed from the first viewpoint arranged in the virtual space. The appearance generation unit 301 is realized by the CPU 101 and the image processing unit 107, for example.

  The display unit 302 displays the state image 410 generated by the state generation unit 301. The display unit 302 is realized by the display 290 or the like.

  The accepting unit 303 accepts an instruction input for designating a target position in the state image 410. The attention position is a position in the image 410 where the user is paying attention. In the shooting game, the target position can be considered as the aiming position in the state image 410. The accepting unit 303 further accepts an instruction input for designating that the bullet object 408 is moved. Here, the bullet object 408 is an object arranged at a movement start position whose relative position is fixed from the first viewpoint among a plurality of objects arranged in the virtual space. In the shooting game, the bullet object 408 can be considered as an object representing a bullet or the like fired at the time of shooting. The accepting unit 403 is realized by the controller unit 105, for example.

  The detail generation unit 304 generates a detail image having a predetermined size smaller than the state image 410 when the degree of change in the target position is equal to or less than a predetermined threshold. Specifically, the detail generation unit 304 generates a detail image based on virtual space information stored in the storage unit 307 described later. Here, the detailed image is an image obtained by enlarging the state represented by the state image 410 around the attention position and cutting out to a predetermined size around the attention position. Therefore, the detailed image is considered to be an image representing a state in which the virtual space is viewed from the second viewpoint approaching the target object 401 drawn at the target position in the state image 410 from the first viewpoint in the virtual space. Can do. The detail generation unit 304 is realized by the CPU 101 and the image processing unit 107, for example.

  The movement unit 305 moves the bullet object 408 from the movement start position to the target object 401 drawn at the target position with the passage of time when an instruction to move is given by the reception unit 303. Specifically, the moving unit 305 calculates the coordinates of the bullet object 408 in the virtual space for each screen update period, and stores information representing the calculated coordinates in the storage unit 307 described later.

  The second instruction image generation unit 306 generates a second instruction image 403 when the degree of change in the target position exceeds a predetermined threshold. An image representing a predetermined object can be adopted as the second instruction image 403. The second instruction image generation unit 306 is realized by the CPU 101 and the image processing unit 107, for example.

  Here, the display unit 302 displays the first instruction image 404 so as to overlap the attention position of the state image 410 when the degree of change of the attention position is equal to or less than a predetermined threshold. On the other hand, when the degree of change in the target position exceeds a predetermined threshold, the display unit 302 displays the second instruction image 403 so as to overlap the target position of the state image 410. Here, the display unit 302 displays an image including the detailed image generated by the detailed generation unit 304 as the first instruction image 404.

  The storage unit 307 stores virtual space information. The virtual space information includes information representing the position, size, shape, and the like in the three-dimensional virtual space of a plurality of objects such as the target object 401 and the bullet object 408 arranged in the three-dimensional virtual space. The storage unit 307 is realized by the RAM 103 or the like.

  Here, the first instruction image 404 and the second instruction image 403 will be described in detail with reference to FIGS. 4A and 4B. FIG. 4A is a diagram for explaining the second instruction image 403. FIG. 4B is a diagram for explaining the first instruction image 404.

  When the degree of change in the target position exceeds a predetermined threshold value, a composite image as shown in FIG. 4A is displayed on the display 290. This composite image is an image in which the state image 410 and the second instruction image 403 are combined so that the second instruction image 403 overlaps the target position of the state image 410. FIG. 4A shows an example in which the second instruction image 403 is displayed superimposed on the target object 401 when the target object 401 is drawn at the target position. In the example shown in FIG. 4A, the second instruction image 403 is an image representing a cross-shaped aim.

  On the other hand, when the degree of change in the target position is equal to or less than the predetermined threshold, a composite image as shown in FIG. 4B is displayed on the display 290. This composite image is an image in which the state image 410 and the first instruction image 404 are combined so that the first instruction image 404 overlaps the target position of the state image 410. Here, in the present embodiment, an image including a detailed image obtained by enlarging the state represented by the state image 410 around the attention position and cutting out the image to a predetermined size around the attention position is the first image. The instruction image 404 is adopted. FIG. 4B shows an example in which the first instruction image 404 is displayed superimposed on the target object 401 when the target object 401 is drawn at the target position. In the example shown in FIG. 4B, the first instruction image 404 is an image representing an enlarged state of the state in the virtual space represented by the portion surrounded by a circle centered on the target position in the state image 410. This is an image obtained by synthesizing the image representing the aim. Accordingly, the first instruction image 404 can be considered as an image representing a state of being projected on the sighting device when the target position is observed using the sighting device.

Here, the first instruction image 404 and the second instruction image 403 will be described with reference to FIGS.
FIG. 5A shows an image 405 obtained by enlarging the state represented by the state image 410 around the position of interest. FIG. 5A shows a black dot 402 indicating the coordinates of the target position for easy understanding. FIG. 5B shows a detailed image 406 cut out from the image 405 to a predetermined size with the target position at the center. FIG. 5C shows an image 407 representing the aiming device. FIG. 5D shows a first instruction image 404 obtained by combining the detailed image 406 and the image 407. FIG. 5E shows a second instruction image 403.
As described above, different composite images are displayed on the display 290 depending on the degree of change in the target position. Note that whether or not the degree of change in the attention position is equal to or less than a predetermined threshold is, for example, whether or not the speed of movement of the attention position or the size of the movement range of the attention position is equal to or less than the predetermined threshold. Can be determined. A specific method for determining whether or not the degree of change in the position of interest is equal to or less than a predetermined threshold will be described later.

(Operation of display device)
Next, the operation of the display device 300 according to the present embodiment will be described with reference to the drawings. FIG. 6 is a flowchart illustrating display control processing executed by the display device 300 according to the present embodiment. Note that the display control process shown in the flowchart of FIG. 6 is executed during the execution of the shooting game by the display device 300.

  First, the CPU 101 determines whether or not the current time is a screen update time (step S101). The screen update time is a time that arrives at every time interval determined by the refresh rate of the display 290, for example, a time that arrives every 1/60 seconds.

  If the CPU 101 determines that the current time is not the screen update time (step S101: NO), the CPU 101 returns the process to the process of determining whether the current time is the screen update time (step S101). On the other hand, when determining that the current time is the screen update time (step S101: YES), the CPU 101 determines whether there is an instruction input for designating the movement of the bullet object 408 (step S102). Specifically, for example, the CPU 101 determines whether or not the B button 214 disposed on the lower surface of the controller 210 has been pressed.

  When the CPU 101 determines that there is an instruction input for designating the movement of the bullet object 408 (step S102: YES), the CPU 101 starts moving the bullet object 408 (step S103). The bullet object 408 is an object arranged at a movement start position where the relative position from the viewpoint of viewing the virtual space represented by the state image 410 is fixed. When the CPU 101 determines that the instruction input has been made, it moves the bullet object 408 from the movement start position to the target object 401 drawn at the target position with the passage of time. Specifically, for example, the CPU 101 sets a movement start flag in the RAM 103. The bullet object 408 is an object representing a bullet, for example.

  After determining that there is no instruction input for designating the movement of the bullet object 408 (step S102: NO), or after finishing the process of starting the movement of the bullet object 408 (step S103), the CPU 101 An image 410 is generated (step S104). Specifically, based on the virtual space information stored in the RAM 103, the CPU 101 generates a state image 410 that represents a state viewed from the first viewpoint arranged in the virtual space. When the movement start flag is set in the RAM 103, the CPU 101 executes the process of generating the state image 410 after updating the coordinate information of the bullet object 408.

  When the CPU 101 ends the generation of the state image 410 (step S104), the CPU 101 acquires the position of interest based on the image transmitted from the controller 210 (step S105). Specifically, first, the CPU 101 obtains the positions of two light emitting points in the image transmitted from the controller 210. Then, the CPU 101 obtains a position where the tip of the controller 210 is directed in the state image 410 displayed on the display 290 based on the positions of the two light emitting points. Here, the CPU 101 treats the obtained position as a target position. The CPU 101 stores information representing the acquired attention position in the RAM 103 or the like. Note that the target position is, for example, a coordinate (hereinafter referred to as “X coordinate”) that indicates a position in the horizontal axis direction with reference to the leftmost end of the display 290 and a position in the vertical axis direction with respect to the lowest end of the display 290. Are represented by dots (hereinafter referred to as “Y coordinates”).

  When the CPU 101 finishes acquiring the attention position (step S105), the CPU 101 acquires the degree of change of the attention position (step S106). How to define the degree of change of the target position is arbitrary, but in the present embodiment, the size of the range of movement of the target position in the recent predetermined period is the degree of change of the target position. Hereinafter, with reference to FIG. 7, a method for acquiring the degree of change in the target position will be described.

  First, the CPU 101 reads all the information representing the ten positions of interest acquired from the RAM 103 during the latest 10 screen update cycles. In FIG. 7, the coordinates of ten attention positions are indicated by x. Next, the CPU 101 selects the attention position Pl having the smallest coordinate in the X-axis direction, the attention position Pr having the largest coordinate in the X-axis direction, and the attention having the smallest coordinate in the Y-axis direction among the ten attention positions. The position Pd and the target position Pu having the largest coordinate in the Y-axis direction are specified. Then, the CPU 101 determines the difference between the movement length Lx in the X-axis direction, which is the difference between the X coordinate of the target position Pl and the X coordinate of the target position Pr, and the Y coordinate of the target position Pd and the Y coordinate of the target position Pu. The movement length Ly in the Y-axis direction is obtained. Here, the CPU 101 obtains a value obtained by multiplying Lx and Ly, and uses the obtained value as the size of the movement range. In FIG. 7, the area of a region surrounded by a rectangle indicated by a broken line is the size of the movement range.

  Returning to the description of FIG. When the CPU 101 completes the process of acquiring the degree of change in the position of interest (step S106), the CPU 101 determines whether the degree of change in the position of interest is equal to or greater than the threshold (step S107). In the present embodiment, since the degree of change of the attention position is the size of the movement range of the attention position, this threshold value is an area threshold value. The threshold value may be a value stored in advance in the ROM 102 or the like, but may be determined according to the shooting skill of the user. This is because the ability to aim when a target is found is considered to vary depending on the shooting skill of the user. That is, a user with a high shooting skill is expected to have a small degree of change in the position of interest after target discovery because the operation of determining the aim is good. On the other hand, users with low shooting skills are not good at aiming operations, so it is expected that the degree of change in the position of interest after target discovery will be large. Therefore, for example, the threshold value is set to be smaller as the score obtained during the shooting game is larger.

  When the CPU 101 determines that the degree of change in the target position is equal to or less than the threshold value, that is, the size of the range of movement of the target position within the predetermined period (step S107: YES), the first instruction An image 404 is generated (step S108). In the present embodiment, the first instruction image 404 is an image including the detailed image 406 (a composite image of the detailed image 406 and the image 407). Hereinafter, the detailed image 406 (the detailed image 803 in the description of FIGS. 8A and B) will be described with reference to FIGS. 8A and 8B.

  As described above, the state image 410 is an image that represents a state viewed from the first viewpoint arranged in the three-dimensional virtual space. In the example shown in FIG. 8A, an image obtained by projecting a state viewed from the first viewpoint V1 onto a projection plane whose distance from the first viewpoint V1 is the distance Dscr is a state image 801 (FIG. 8A). In the description other than B, the state image 410) is used. In the present embodiment, the state image 801 is an image having a size of 640 (dot) × 480 (dot). In the present embodiment, the projection surface is described as a flat surface, but the projection surface may be a curved surface. Here, the size of the target object 401 in the state image 801 is determined by the size of the target object 401 in the three-dimensional virtual space and the distance Dtar1 that is the distance from the first viewpoint V1 to the target object 401. Therefore, the size of the target object 401 in the state image 801 is smaller as the distance Dtar1 is longer, and is larger as the distance Dtar1 is shorter.

  On the other hand, the detailed image 803 is an image obtained by enlarging the state represented by the state image 801 around the attention position and cutting out to a predetermined size around the attention position. Here, in FIGS. 8A and 8B, description will be made assuming that the target position is the position of the center of gravity of the target object 401 represented in the state image 801. In the present embodiment, the detailed image 803 is an image representing a state in which the 3D virtual space is viewed from the second viewpoint V2 arranged in the 3D virtual space. Here, the second viewpoint V2 is a viewpoint approaching from the first viewpoint V1 to the target object 401 drawn at the position of interest in the state image 801 in the three-dimensional virtual space. In the example shown in FIG. 8B, the state seen from the second viewpoint V2 approaching the target object 401 from the first viewpoint V1 is projected onto the projection plane whose distance from the second viewpoint V2 is the distance Dscr. The image obtained by the above is an image 802. This image 802 is an image representing a state in which the state represented by the state image 801 is enlarged around the position of interest. In the present embodiment, the image 802 is an image having a size of 640 (dot) × 480 (dot). A detailed image 803 is an image cut out from the image 802 to a predetermined size around the position of interest. The detailed image 803 is not an image cut out from an image obtained by simply enlarging the state image 801 but is an image representing a state viewed from a viewpoint closer to the target object 401 than the state image 801. Therefore, the detailed image 803 is an image that clearly represents the state of the three-dimensional virtual space represented by the image near the target position.

  Here, the size of the detailed image 803 cut out from the image 802 is determined according to the degree of change in the target position. For example, the smaller the degree of change in the attention position, that is, the smaller the size of the movement range of the attention position, the larger the detailed image 803 becomes. This is because it is considered that the aim is determined as the degree of change in the attention position is smaller, that is, as the size of the movement range of the attention position is smaller. That is, as the change in the aiming position is smaller, the target object 401 drawn at the target position is presented in more detail, so that the user can determine the aim more accurately.

  The size of the target object 401 in the image 802 is determined by the size of the target object 401 in the three-dimensional virtual space and the distance Dtar2 that is the distance from the second viewpoint V2 to the target object 401. Accordingly, the size of the target object 401 in the image 802 becomes smaller as the distance Dtar2 is longer, and larger as the distance Dtar2 is shorter. Further, the detailed image 803 is an image representing a state where the state represented by the state image 801 is enlarged by Dtar1 / Dtar2 times.

Here, for example, when the enlargement ratio is constant, the ratio of the distance from the first viewpoint V1 to the target object 401 and the distance from the second viewpoint V2 to the target object 401 is a constant ratio. To do. Specifically, the second viewpoint V2 is determined such that the ratio between the distance D12 and the distance Dtar1, which is a distance obtained by subtracting the distance Dtar2 from the distance Dtar1, is a constant value. That is, the distance D12 that is the distance from the first viewpoint V1 to the second viewpoint V2 is set to a length that is associated with the distance Dtar1 in advance.
This is the end of the description of the detailed image 803, and the description returns to the flowchart of FIG.

  If the CPU 101 determines that the degree of change of the target position is not less than or equal to the threshold value, that is, the size of the range of movement of the target position in the predetermined period is not within the predetermined range (step S107: NO), the second instruction An image 403 is generated (step S109). The second instruction image 403 is an image representing a predetermined object, and is an image different from the first instruction image 404. The second instruction image 403 can be, for example, an image as shown as the second instruction image 403 in FIG. 4A. In this way, by making the second instruction image 403 different from the first instruction image 404, it is possible to indicate to the user whether or not the degree of change in the position of interest is below a predetermined threshold.

  When the CPU 101 finishes the process of generating the first instruction image 404 (step S108) or the process of generating the second instruction image 403 (step S109), the CPU 101 generates a composite image (step S110). The composite image is composed of the state image 410 generated in step S104 and either the first instruction image 404 generated in step S108 or the second instruction image 403 generated in step S109. It is an image obtained by this. For example, the composite image may be an image in which the first instruction image 404 or the second instruction image 403 is overwritten with the state image 410 as a background image. In this case, the first instruction image 404 or the second instruction image 403 may be displayed translucently.

  When the CPU 101 finishes the process for generating the composite image (step S110), the CPU 101 displays the composite image (step S111). Specifically, the CPU 101 supplies a signal representing the composite image generated in step S110 to the display 290. On the other hand, the display 290 displays a composite image according to the supplied signal.

When the CPU 101 ends the process of displaying the composite image (step S111), the CPU 101 returns the process to the process of determining whether it is the screen update time (step S101).
Above, description of the display control process which the display apparatus 300 performs is complete | finished.

According to the display device 300, when the degree of change of the attention position is small, that is, when the size of the movement range of the attention position in the predetermined period is within the predetermined range, the first instruction is given to the attention position of the appearance image 410. When the image 404 is displayed in an overlapping manner and the degree of change of the target position is large, that is, when the size of the range of movement of the target position in the predetermined period is not within the predetermined range, the second position is displayed at the target position of the state image 410. The instruction image 403 is displayed in an overlapping manner. Therefore, according to the display device 300, whether or not the degree of change in the attention position is equal to or less than the predetermined threshold, that is, whether or not the size of the movement range of the attention position in the predetermined period is equal to or less than the predetermined size. And the position of interest can be presented.
Further, the first instruction image 404 is an image including a detailed image 406 obtained by enlarging the state represented by the state image 410 around the position of interest and cutting it out to a predetermined size around the position of interest. For this reason, according to the display apparatus 300, information can be presented in order to specify the position of interest more accurately.
Further, according to the display device 300, the enlargement ratio of the detailed image 406 can be adjusted by appropriately adjusting the second viewpoint V2.
Further, according to the display device 300, the smaller the degree of change in the position of interest, the larger the detailed image 406 can be made.
As described above, according to the display device 300 according to the present embodiment, it is possible to present the degree of change of the position focused by the user in an easy-to-understand manner.

(Second Embodiment)
In the first embodiment, an example in which the present invention is applied to a display device that displays an image representing a state of viewing a three-dimensional virtual space in which a plurality of objects are arranged has been described. However, the present invention can also be applied to a display device that displays an image representing a state in which a desktop space where a plurality of windows or icons are arranged is viewed. The display device according to the second embodiment will be described below. Note that the display device according to the second embodiment can be realized by using, for example, a personal computer. In this case, the above-described receiving unit 303 is realized by a mouse, a keyboard, or the like. However, the configuration of the display device and the display control process according to the second embodiment are basically the same as those of the first embodiment.

  In the present embodiment, an image representing a state in which a desktop space in which a plurality of windows or icons are arranged is viewed is generated as the state image 910. An instruction input for designating a target position in the state image 910 is accepted by a mouse or a keyboard. In the present embodiment, the position of interest does not change unless the mouse or keyboard is operated. Therefore, basically, the first instruction image 902 is displayed so as to overlap the attention position of the state image 910, and the second instruction image 901 is displayed at the attention position of the state image 910 when a mouse, a keyboard, or the like is operated. Overlaid. Hereinafter, with reference to FIGS. 9A and 9B, an image displayed by the display device according to the second embodiment will be described.

  When the degree of change of the attention position exceeds a predetermined threshold, for example, when the size of the movement range of the attention position within a predetermined period is within a predetermined range, a composite image as shown in FIG. 9A is displayed on the display 290. Is displayed. This composite image is an image in which the state image 910 and the second instruction image 901 are combined so that the second instruction image 901 overlaps the target position of the state image 910. FIG. 9A shows an example in which the second instruction image 901 is displayed superimposed on the character string “KB” when the character string “KB” as the target object is drawn at the target position. In the example shown in FIG. 9A, the second instruction image 901 is an image representing an arrow pointer.

On the other hand, when the degree of change of the attention position is equal to or less than a predetermined threshold, for example, when the size of the movement range of the attention position in the predetermined period is not within the predetermined range, the display 290 has a display as shown in FIG. 9B. A composite image is displayed. This composite image is an image in which the state image 910 and the first instruction image 902 are combined such that the first instruction image 902 overlaps the target position of the state image 910. Here, in the present embodiment, an image including a detailed image obtained by enlarging the state represented by the state image 910 around the position of interest and cutting out to a predetermined size around the position of interest is the first image. The instruction image 902 is used. FIG. 9B shows an example in which the first instruction image 902 is displayed superimposed on the character string “KB” when the character string “KB” as the target object is drawn at the target position. In the example shown in FIG. 9B, the first instruction image 902 includes a detailed image obtained by enlarging an image represented by a region surrounded by a circle centered on the position of interest in the state image 910, and an image representing a magnifying glass. It is an image obtained by synthesizing. Therefore, the first instruction image 902 can be considered as an image representing a state that can be seen when the target position is observed using a magnifying glass.
In this way, different composite images are displayed on the display 290 depending on the degree of change in the target position.

In the present embodiment, when there is no operation with a mouse, a keyboard, or the like, a relatively large first instruction image 902 that enlarges and displays an area near the target position is displayed superimposed on the target position of the state image 910, and When there is an operation with a keyboard or the like, a relatively small second instruction image 901 is displayed at the target position of the state image 910. For this reason, when the user is not operating the mouse or the keyboard, the user can observe the details of the target object drawn at the target position. On the other hand, when the user is operating a mouse, a keyboard, or the like, the user can move the target position accurately.
As described above, according to the display device 300 according to the present embodiment, it is possible to present the degree of change of the position focused by the user in an easy-to-understand manner.

(Modification)
In the above-described embodiment, an image composed of the detailed image 406 and the image 407 obtained by enlarging the state represented by the state image 410 around the attention position and cutting out to a predetermined size around the attention position. An example in which the first instruction image 404 is used is shown. However, the first instruction image 404 may be any image as long as it is different from the second instruction image 403. For example, as shown in FIG. 10, an image 407 representing the sighting device can be used as the first instruction image 404. Accordingly, it is possible to present that the aim is determined, and it is possible to present the position where the aim is determined in the state image 410. Further, the detailed image 406 itself may be the first instruction image 404.

In the above-described embodiment, an example in which the second instruction image 403 is displayed so as to overlap the attention position of the state image 410 when the degree of change in the attention position exceeds a predetermined threshold value has been described. However, the second instruction image 403 is not necessarily displayed. This is because the degree of change of the target position can be presented depending on whether or not the first instruction image 404 is displayed.
Further, the second instruction image 403 can be an image having the same shape as the first instruction image 404 and a color different from that of the first instruction image 404. Even in such a case, it is possible to present the degree of change of the target position.

  In the above embodiment, an example in which the second viewpoint V2 is determined so that the enlargement ratio of the detailed image 406 is constant has been described. However, for example, the size of the target object 401 on the display 290 may be constant. In this case, the second viewpoint V2 is determined so that the distance from the second viewpoint V2 to the target object 401 is a constant distance.

  In the embodiment described above, the size of the moving range of the target position in the predetermined period is the leftmost, rightmost, lowermost, and lowest positions of the target positions sampled in the predetermined period with a predetermined sampling cycle (screen update cycle). The example shown based on the coordinate of an upper end was shown. However, how to define the size of the movement range of the target position is arbitrary. For example, the size of the movement range of the target position can be defined as the distance between the two most distant target positions among the target positions sampled at a predetermined sampling period in a predetermined period. Further, for example, the size of the moving range of the target position is defined as the distance from the target position farthest from the center of gravity of the target position to the center of gravity of the target position among the target positions sampled at a predetermined sampling period in a predetermined period. can do. In addition, for example, the size of the moving range of the target position is set to a figure (polygon, circle, ellipse) of a predetermined shape with the smallest area surrounding all the target positions sampled at a predetermined sampling period in a predetermined period. It can be defined as area.

  In the above-described embodiment, an example in which the degree of change in the attention position is set to the size of the movement range of the attention position in the predetermined period is shown. However, the degree of change of the target position can be set as an average value of the moving speed of the target position in a predetermined period. For example, the position of interest is sampled at a predetermined sampling period within a predetermined period, and the speed of movement of the position of interest is determined by obtaining a difference from the previously sampled position of interest. Then, an average value of the moving speed of the target position obtained for each predetermined sampling period within the predetermined period in the predetermined period is set as the degree of change of the target position.

  In the above-described embodiment, the example in which the degree of change of the target position is acquired based on the ten target positions sampled for each screen update period in the period of ten screen update periods. However, the period for sampling the position of interest and the period for sampling the position of interest can be adjusted as appropriate.

  In the above embodiment, an example in which the detailed image 406 is generated separately from the state image 410 has been described. However, an image cut out to a predetermined size from the image obtained by enlarging the state image 410 with the attention position at the center may be the detailed image 406. According to such a method, it can be expected that the time for generating the detailed image 406 is shortened.

  As described above, according to the present invention, it is possible to provide a display device, a display method, and a program for realizing these by a computer, which are suitable for presenting the degree of change in the position of interest of the user in an easy-to-understand manner. be able to.
