Description

  The present invention relates to a display device, a display method, and a program that are suitable for facilitating visual recognition of an object to be noted when a transmissive display is used on another display.

  A technology of a display device (hereinafter referred to as “multi-layer display”) is known in which an image is displayed in a three-dimensional manner by superimposing a transmissive display on a normal image display and displaying the image on each display. For example, Patent Document 1 discloses a technique in which an ordinary display, a microlens array, and a transmissive display are arranged so as to overlap each other so that an image can be viewed three-dimensionally. In recent years, it has been desired to apply such a technique to a game to enable realistic game play.

  However, in general, a transmissive display has a low luminance, and when a game image is displayed on the transmissive display, there is a problem that it is difficult to see a noticeable object, a character, or the like.

  The present invention solves the above-described problems, and a display device, a display method, and a display device suitable for facilitating visual recognition of an object to be noticed when a transmissive display is used on another display. The purpose is to provide a program.

  A display device according to a first aspect of the present invention includes a first generation unit, a second generation unit, a first display unit, a second display unit, and an acquisition unit, as described below. Configure. In the following, a case where a game image is displayed on a multi-layer display in a dance game in which steps are taken according to an object displayed on the screen will be described as an example.

  The first generation unit generates a first image in which a first object is drawn on a background image including a transparent or translucent area.

  For example, the first object is an object to be noticed in the dance game and is an object indicating the direction of the step (hereinafter referred to as “direction object”), and the first generation unit has a color so that the player can visually recognize it. An image including the attached direction object and a transparent or translucent area is generated.

  The second generation unit generates a second image.

  For example, the second generation unit generates an image serving as a background of the first image, such as a lane in which a character or a direction object moves, or a score.

  The first display unit displays the first image on the first screen.

  Here, the first screen is a transmissive display, and the first display unit displays an image composed of a transparent or translucent area and a non-transparent object on the transmissive display. In the example of the dance game, only the direction object is colored and displayed so as to be visible, and the other areas are displayed transparently.

  The second display unit displays the second image on the second screen arranged to overlap the first screen.

  Here, the second screen is a normal liquid crystal display, and is disposed so as to overlap the transmissive display. That is, if the first screen (transmission type display) and the second screen (ordinary liquid crystal display) are placed upright in the vertical direction, the first screen is arranged in front of the player as viewed from the player side. This screen is arranged in the back of the first screen when viewed from the player side so as to overlap the first screen. The second display unit displays an image as a background of a character or the like on the liquid crystal display. By arranging the first screen and the second screen in this manner and displaying the images on each, the direction object displayed on the first screen is displayed on the front side for the dance game player. It is possible to make it appear as if the characters displayed on the screen are arranged in the back.

  The acquisition unit acquires a position in the second image corresponding to a position where the first object is drawn in the first image.

  Here, the corresponding position is a position where the first object is projected onto the second image displayed on the second display unit, or a position shifted by a predetermined distance from the projected position. For example, the acquisition unit acquires a position where a directional object displayed on a transmissive display is projected on a normal display.

  Then, when the color of the first object is similar to the color of the second image drawn at the position acquired by the acquisition unit, the second generation unit selects a color different from the color of the first object. The second object is drawn at the acquired position.

  For example, the position acquired by the acquisition unit is set to a position shifted by a predetermined distance from the position where the direction object is projected on the second image. When the color displayed at the position shifted by the predetermined distance is similar to the color of the direction object, an object having a color different from the direction object is drawn at a position shifted by the predetermined distance on the second image. .

  According to the present invention, even when the color of an object displayed on a transmissive display is similar to the color of an image of a normal display displayed behind the object, an object having a different color from the object is displayed. By drawing on a normal display, it is possible to make the object of the transmissive display stand out and make it easier to visually recognize the object.

  When the position acquired by the acquisition unit is within a predetermined range, the second generation unit may change the size of the second object.

  For example, in a dance game, a direction object moves on the screen, and when the direction object reaches an area called a determination area, it is required to step in the direction indicated by the direction object. If the predetermined range is the determination area, the second generation unit increases the size of the second object, for example, when the direction object reaches the determination area. As a result, the position of the direction object and the second object displayed in the back can be made closer, and the determination area can be felt to be thick.

  According to the present invention, it is possible to provide a visual effect such that there is unevenness in a predetermined range, thereby making it easy to visually recognize an object in the predetermined range.

  When the position acquired by the acquisition unit is within a predetermined range, the second generation unit may shift the position for drawing the second object.

  For example, when the direction object reaches the determination area, the second generation unit further shifts the position of the second object from the position displayed so far. Accordingly, it is possible to make the second object appear to be separated from the direction object, and it is possible to make the user feel as if there is a depression in the determination area.

  According to the present invention, it is possible to provide a visual effect such that there is unevenness in a predetermined range, thereby making it easy to visually recognize an object in the predetermined range.

  The first object and the second object may be similar.

  For example, when the direction object has the shape of an arrow, the second object that is a shadow is also in the shape of an arrow of an arbitrary size.

  According to the present invention, it is possible to give a visual effect such that a notable object has a shadow.

  The different color may be a color having a high contrast with the color of the first object.

  For example, when the direction object is white, the second object is generated in black, which is a color in which white stands out.

  According to the present invention, even when the color of an object displayed on a transmissive display is similar to the color of an image of a normal display displayed behind the object, it has a color that makes the object stand out. By displaying the object on a normal display, the object of the transmissive display can be easily viewed.

  Further, the different color may be different from the color of the second image drawn at the position acquired by the acquisition unit.

  For example, if it is determined that the direction object is white, the color displayed at the position where the direction object is projected in the second image is light gray, and the two colors are similar, Change the object color to something other than light gray.

  According to the present invention, even when the color of an object displayed on a transmissive display is similar to the color of an image of a normal display displayed behind the object, the color is different from that of the object, and By displaying an object having a color different from the color displayed at a corresponding position in a normal display, the object of the transmissive display can be easily viewed.

  A display method according to a second aspect of the present invention is executed by a display device including a first generation unit, a second generation unit, a first display unit, a second display unit, and an acquisition unit. A display method, which includes a first generation process, a second generation process, a first display process, a second display process, and an acquisition process, and is configured as follows.

  In the first generation step, the first generation unit generates a first image in which the first object is drawn on a background image including a transparent or translucent region.

  In the second generation step, the second generation unit generates a second image.

  In the first display step, the first display unit displays the first image on the first screen.

  In the second display step, the second display unit displays the second image on the second screen arranged so as to overlap the first screen.

  In the acquisition step, the acquisition unit acquires a position in the second image corresponding to a position where the first object is drawn in the first image.

  In the second generation step, when the color of the first object is similar to the color of the second image drawn at the position acquired by the acquisition unit, the second generation unit A second object having a color different from the first color is drawn at the acquired position.

  A program according to another aspect of the present invention is configured to cause a computer to function as the display device and to cause the computer to execute the display method.

  The program of the present invention can be recorded on a computer-readable information recording medium such as a compact disk, flexible disk, hard disk, magneto-optical disk, digital video disk, magnetic tape, and semiconductor memory.

  The above program can be distributed and sold via a computer communication network independently of the computer on which the program is executed. The information recording medium can be distributed and sold independently of the computer.

  According to the present invention, it is possible to provide a display device, a display method, and a program that are suitable for facilitating visual recognition of an object to be noticed when the transmissive display is used on another display.

Is realized. In the following embodiment, an image displayed in a dance game will be described as an example.

(Embodiment 1)
The display device according to the first embodiment displays an object that is a shadow of an object of a transmissive display on a normal display.

  As illustrated in FIG. 2, the display device 200 according to the first embodiment includes a first generation unit 201, a second generation unit 202, a first display unit 203, a second display unit 204, and an acquisition unit 205. And is configured as follows. In the following description, the first screen 301 (transmission type display) and the second screen 302 (normal display) constitute a multilayer display 300, and the display device 200 includes a first display on the multilayer display 300. Assume that an image 401 and a second image 402 are output.

  First, a game image of a dance game displayed on the multi-layer display 300 will be described.

  In the game image of the dance game of FIG. 3, a plurality of types of target objects MO1 to MO4 are synchronized with the rhythm of the musical piece to be played, along the moving lane La (lane corresponding to the type of object) from below. It shows how they appear sequentially, move upwards, and then disappear. The target objects MO1 to MO4 represent arrow symbols in different directions. The target object MO1, which is a right-pointing arrow symbol, instructs the player to move the center of gravity in the right direction. Similarly, the target object MO2 that is a downward arrow symbol is directed backward, the target object MO3 that is an upward arrow symbol is forward, and the target object MO4 that is a left arrow symbol is directed leftward. Is.

  These target objects MO1 to MO4 appear from the lower end (starting point) of the moving lane La, move upward in the moving lane La, and disappear at the upper end (end point) of the moving lane La. Then, the player is requested to perform an action corresponding to the target object when any one of the target objects MO1 to MO4 reaches the determination area HA (an area in which objects having the same shape as each target object are fixedly arranged). Is done. That is, when the objects completely overlap in the determination area HA, an operation for moving the center of gravity in the designated direction is required. Hereinafter, the time when the objects are completely overlapped in the determination area HA is defined as the timing to move. When the objects completely overlap in the determination area HA, if the player steps in the indicated direction, the score is added, and for example, the score is displayed on the screen as “123400” in FIG. On the other hand, when the objects are completely overlapped in the determination area HA, the score is subtracted when there is no input by the player or when the step is not stepped in the indicated direction. Further, the smaller the error between the timing of stepping and the timing at which objects completely overlap in the determination area HA, the higher the score may be obtained.

  The game image in FIG. 3 shows a case where the target objects MO1 to MO4 move from the lower side to the upper side of the screen, but the moving direction of the target object is not limited to this and is arbitrary. For example, the screen may be moved from the upper side to the lower side, or may be moved in the horizontal direction (from the right side to the left side of the screen or from the left side to the right side of the screen). Further, instead of the determination area HA, a determination line orthogonal to the moving lane La may be displayed and used as an area for determination. The moving lane La may be hidden in the game image, and the shape of the target object may be another shape.

  In the multi-layer display 300, the target objects MO1 to MO4 of the game image of FIG. 3 are displayed on the transmissive display as shown in FIG. 4A, and the other images are usually displayed as shown in FIG. 4B. Appears on the display.

The 1st production | generation part 201 produces | generates the image for displaying on the 1st screen 301 (transmission type display). The first generation unit 201 generates a first image 401 in which a first object is drawn on a background image including a transparent or translucent area. For example, the first objects are the target objects MO1 to MO4, and the first generation unit 201, as shown in FIG. 4A, can visually recognize the target objects MO1 to MO4 and other than the target objects MO1 to MO4. An image having a transparent area is generated. Then, the first generation unit 201 stores the image data in a frame memory included in the image processing unit 107.
Therefore, the CPU 101 and the image processing unit 107 cooperate to function as the first generation unit 201.

The second generation unit 202 generates a second image 402 to be displayed on the second screen 302 (normal display). For example, the second generation unit 202 generates the image shown in FIG. Then, the second generation unit 202 stores the image data in a frame memory included in the image processing unit 107.
Therefore, the CPU 101 and the image processing unit 107 cooperate to function as the second generation unit 202.

The first display unit 203 displays the first image 401 generated by the first generation unit 201 on the first screen 301. For example, the first display unit 203 determines whether or not a vertical synchronization interrupt has occurred. When the vertical synchronization interrupt occurs, the first display unit 203 transfers the data of the first image 401 stored in the frame memory to the transmissive display. The image shown in 4 (a) is displayed on the transmissive display.
Therefore, the CPU 101 and the image processing unit 107 cooperate to function as the first display unit 203.

The second display unit 204 displays the second image 402 generated by the second generation unit 202 on the second screen 302 that is arranged so as to overlap the first screen 301. For example, the second display unit 204 determines whether a vertical synchronization interrupt has occurred. When the vertical synchronization interrupt occurs, the second display unit 204 transfers the data of the second image 402 stored in the frame memory to a normal display, The image shown in FIG. 4B is displayed on a normal display.
Therefore, the CPU 101 and the image processing unit 107 cooperate to function as the second display unit 204.

The acquisition unit 205 acquires a position in the second image 402 corresponding to a position where the first object is drawn in the first image 401. Here, the “corresponding position” refers to a position where the first object is projected onto the second image 402 (hereinafter referred to as “projection position”), or a position shifted from the projection position by a predetermined distance (hereinafter referred to as “projection position”). (Referred to as “predetermined position”).
Accordingly, the CPU 101 and the image processing unit 107 cooperate to function as the acquisition unit 205.

  FIG. 5A shows the first image 401 viewed from the front in the horizontal direction and FIG. 5B shows the second image 402 when the multilayer display 300 is placed vertically. Here, the first image 401 and the second image 402 have the same size (I × J, I: any number, J: any number), and the coordinates (i, j) are on the memory frame. Value. It is assumed that the coordinates P1_1 (i, j) in the first image 401 and P2_1 (i, j) in the second image 402 are completely coincident when displayed on the multilayer display 300 in an overlapping manner. Assuming that the position where the first object (target object MO3) is drawn in the first image 401 is P1_1 (i, j) and the “corresponding position” is the projection position, the acquisition unit 205 obtains P2_1 (i, j ) (FIG. 5B) is acquired. If the predetermined distance is 10 pixels and the “corresponding position” is a predetermined position, the acquiring unit 205 acquires the coordinates of P2_2 (i + 10, j + 10) (FIG. 5B).

  Then, as described above, when the acquisition unit 205 acquires the position of the first object on the second image 402, the CPU 101 sets the color of the first object and the position acquired by the acquisition unit 205. It is determined whether or not the color of the second image 402 being drawn is similar. Here, the color of the second image 402 to be compared with the color of the first object is not the color of the pixel at the position (P2_1 or P2_2) acquired by the acquisition unit 205, but the position (P2_1) acquired by the acquisition unit 205. Alternatively, the color of a predetermined area including P2_2) may be used. For example, the color of the area MO3 ′ (FIG. 5B) obtained by projecting the target object MO3 onto the second image 402 is compared with the color of the target object MO3. Alternatively, the color included in the region MO3 ″ obtained by shifting the projected region MO3 ′ to the predetermined position (P2_2) is compared with the color of the target object MO3. Hereinafter, the color of the first object and the color of the first object are compared. Based on the color of the region MO3 ′ projected on the second image 402, a color similarity determination is performed.

  If the CPU 101 determines that the images are similar to each other, the second generation unit 202 draws at a position having a shape similar to that of the first object, a color different from the color of the first object, and acquired by the acquisition unit 205. A second object having a color different from the color of the second image 402 being drawn is drawn at the acquired position. In the present embodiment, the “different color” is a color that has a high contrast with the first object.

  Here, the similarity of colors is determined based on each element of the HSV model, for example. The HSV model is a model in which colors are expressed by elements of hue, saturation, and value of brightness. Hue is a value indicating the type of color, and is expressed in the range of 0 to 360. For example, red is represented by 0, yellow by 60, and blue by 210. Saturation is a value indicating the vividness of the color, and is expressed in a range of 0 to 100%. The lower the value, the darker the color. The brightness is a value representing the brightness of the color, and is expressed in a range of 0 to 100%. The higher the value, the brighter the color.

  Hue / saturation / lightness values are assigned to the pixels constituting the first and second images 401 and 402 of the present embodiment, and the CPU 101 displays the first image 401 displayed on the first image 401. The color of the second object 402 and the color of the second image 402 at the position corresponding to the first object are compared in hue, saturation, and brightness. If the difference between the values is equal to or smaller than a predetermined threshold, the CPU 101 determines that the colors are similar. For example, in each element, the average value of the values included in the pixels constituting the target object MO3 is compared with the average value of the values included in the pixels included in the region MO3 ′. Note that the predetermined threshold may be appropriately determined by the player. Further, the value representing the color is not limited to the value of each element of the HSV model, and may be the value of each element of the RGB model, for example.

  For example, in FIG. 5, the target object MO3 included in the first image 401 is uniformly white (FIG. 5A), and the second image 402 is uniformly white (FIG. 5B). ). Accordingly, since the color of the region MO3 ′ onto which the target object MO3 is projected is white, the CPU 101 determines that the color of the second image 402 at a position corresponding to the target object MO3 is similar. When the first image 401 in FIG. 5A and the second image 402 in FIG. 5B are superimposed (FIG. 5C), the color and background of the object of interest (target object MO3) Therefore, when viewed on the multilayer display 300, an object to be noticed (target object MO3) is difficult to visually recognize.

  On the other hand, in FIG. 6, the target object MO3 included in the first image 401 is uniformly white (FIG. 6A), and the second image 402 is uniformly gray (FIG. 6B). ). Accordingly, since the color of the region MO3 ′ onto which the target object MO3 is projected is white, the CPU 101 determines that the color of the second image 402 at a position corresponding to the target object MO3 is not similar. When the first image 401 in FIG. 6A and the second image 402 in FIG. 6B are superimposed (FIG. 6C), the color and background of the object to be noticed (target object MO3) Therefore, when viewed on the multilayer display 300, an object to be noticed is easy to visually recognize.

  When the CPU 101 determines that the color of the second image 402 at a position corresponding to the target object MO3 is similar, that is, when the target object MO3 is difficult to visually recognize, the second generation unit 202 performs processing as illustrated in FIG. In addition, the second object SO3 similar to the first object is drawn on the second image 402 with a color (in this case, dark gray) having a high contrast with the color of the first object. In the present embodiment, it is assumed that the first object (target object MO3) and the second object SO3 have the same size.

  For example, when the position acquired by the acquisition unit 205 is the projection position (P2_1), the second generation unit 202 generates the second object SO3 as illustrated in FIG. 7B. In this case, when the multilayer display 300 is viewed from the front, the first object (target object MO3) and the second object SO3 are completely matched. However, since there is usually a certain distance between the transmissive display that is the first screen 301 and the normal display that is the second screen 302, the diagonal display is slightly offset from the front of the multilayer display 300. Looking at the screen, the second object looks like a shadow. Thereby, a 1st object can be shown in three dimensions.

  On the other hand, when the position acquired by the acquisition unit 205 is the predetermined position (P2_2), the second generation unit 202 generates the second object SO3 as shown in FIG. 8B. In this case, even when viewed from directly in front of the multi-layer display 300, the first object appears to be shaded, and the first object can be seen three-dimensionally.

  In FIG. 6, the CPU 101 determines that the color of the target object MO3 is similar to the color of the projected region MO3 ′ based on a predetermined threshold, and the position acquired by the acquisition unit 205 is In the case of the predetermined position (P2_2), as shown in FIG. 9B, the second generation unit 202 uses the second color of a color different from the target object MO3 and a color different from that of the second image 402 at the predetermined position. Object SO3 is generated. Accordingly, it is possible to add a shadow to the first object so that the image can be determined as the background image.

  Hereinafter, operations performed by each unit of the display device 200 of the present embodiment will be described. When the display device 200 is powered on, the CPU 101 starts display processing shown in the flowchart of FIG.

  The first generation unit 201 reads game image data from the DVD-ROM, and generates a first image 401 (step S101). For example, the first generation unit 201 generates the image of FIG. In addition, the second generation unit 202 reads game image data from the DVD-ROM and generates a second image 402 (step S102). For example, the second generation unit 202 generates the image shown in FIG.

  Next, the acquisition unit 205 acquires a position (predetermined position) corresponding to the first object (step S103). For example, if the coordinates of the first object are P1_1 (i, j), the acquisition unit 205 acquires coordinates P2_2 (i + 10, j + 10) that are shifted from the first object by 10 pixels in the vertical and horizontal directions.

  The CPU 101 determines whether or not the color of the first object is similar to the color of the second image 402 drawn at the position acquired by the acquisition unit 205 (step S104). When it is determined that the CPU 101 is similar (step S104; Yes), the second generation unit 202 has a color different from that of the second image 402 at a predetermined position and a color different from that of the first object. A second object having a similar shape is generated at the position acquired by the acquisition unit 205 (step S105). For example, as shown in FIG. 5, when the color of the target object MO3 and the color of the region MO3 ′ projected onto the second image 402 are similar, the second generation unit 202 performs the second processing shown in FIG. Object SO3 is generated. On the other hand, when the CPU 101 determines that they are not similar (step S104; No), the process proceeds to step S106.

  The first display unit 203 displays the first image 401 on the first screen 301 (step S106), and the second display unit 204 displays the second image 402 on the second screen 302 (step S107). ). For example, the first display unit 203 displays the image shown in FIG. 8A on a transmissive display, and the second display unit 204 displays the image shown in FIG. 8B on a normal display. As a result, the image shown in FIG. 8C is presented to the player.

The CPU 101 determines whether there is an instruction to stop reproduction (step S108). When there is an instruction to stop reproduction (step S108; Yes), the CPU 101 ends the process, and when there is no instruction to stop reproduction (step S108; No), the CPU 101 repeats the process from step S101.
Note that steps S101 and S102, and steps S106 and S107 may be performed in the reverse order or simultaneously.

  According to the present embodiment, by drawing an object of a color different from the object behind the object displayed on the transmissive display, the object displayed on the transmissive display has a shadow. An effect can be provided and the object can be easily visually recognized.

(Embodiment 2)
The display device according to the second embodiment employs a method of adjusting the position and size of an object displayed on a normal display according to the position of the object of the transmissive display.

  As illustrated in FIG. 2, the display device 200 according to the second embodiment includes a first generation unit 201, a second generation unit 202, a first display unit 203, a second display unit 204, and an acquisition unit 205. And is configured as follows. The first generation unit 201, the first display unit 203, the second display unit 204, and the acquisition unit 205 of the present embodiment have the same functions as those of the first embodiment. Hereinafter, the second generation unit 202 having different functions will be described.

The second generation unit 202 generates a second image 402 to be displayed on the second screen 302. If the color of the first object is similar to the color drawn at the position (projection position, predetermined position, or area including them) acquired by the acquisition unit 205 in the second image 402, the second generation The unit 202 has a second color having a color different from the color of the first object at the acquired position and a color different from the color of the second image 402 drawn at the position acquired by the acquisition unit 205. Draw the object. Further, it is assumed that the second object has a similar shape to the first object. Then, when the position acquired by the acquisition unit 205 is within a predetermined range, the second generation unit 202 shifts the position where the second object is drawn, or changes the size of the second object.
Therefore, the CPU 101 and the image processing unit 107 cooperate to function as the second generation unit 202.

  Hereinafter, in the present embodiment, it is assumed that the predetermined range is the determination area HA of FIG.

  For example, when the position (P2_2, FIG. 8B) acquired by the acquisition unit 205 is in the determination area HA, the second generation unit 202 has a similar shape to the target object MO3 as illustrated in FIG. 11B. Is generated at a position (P2_3 (i + 20, j + 20)) further shifted from the currently displayed position (P2_2, FIG. 8B). When the first image 401 in FIG. 11 (a) and the second image 402 in FIG. 11 (b) are superimposed (FIG. 11 (c)), the target object MO3 floats more than the image shown in FIG. 8 (c). Can look like.

FIG. 12 shows an example of a game image in which the position of the second object is further shifted when the acquired position falls within a predetermined range.
The second object SO3 of the target object MO3 that is in the determination area HA is more than the second object SO1, SO2, and SO4 of the target objects MO1, MO2, and MO4 that are not in the determination area HA. Displayed away from the center. In this way, when the position of the second object corresponding to the target object that has entered the determination area HA is further shifted, the position of the object and the shadow can appear to be separated from each other, and there is a depression in the determination area HA. Can be felt.

  Also, for example, when the position (P2_3, FIG. 11B) acquired by the acquisition unit 205 is in the determination area HA, the second generation unit 202, as shown in FIG. A second object SO3 having a similar shape and the same size is generated at the acquired position (P2_3). On the other hand, when the position (P2_3) acquired by the acquisition unit 205 is not in the determination area HA, the second generation unit 202 is similar in shape to the target object MO3 and is from the target object MO3 as shown in FIG. Is generated at the acquired position (P2_3). When the first image 401 in FIG. 13A and the second image 402 in FIG. 13B are overlapped (FIG. 13C), the target object MO3 is floated more than the image shown in FIG. Can look like.

FIG. 14 shows an example of a game image in which the size of the second object is changed when the acquired position falls within a predetermined range.
The second object SO3 of the target object MO3 that is in the determination area HA is displayed larger than the second objects SO1, SO2, and SO4 of the target objects MO1, MO2, and MO4 that are not in the determination area HA. The As described above, when the size of the second object corresponding to the target object entering the determination area HA is increased, it can be seen that the positions of the object and the shadow are closer, that is, in the determination area HA portion. You can make it feel thick.

  Hereinafter, operations performed by each unit of the display device 200 of the present embodiment will be described. When the display device 200 is powered on, the CPU 101 starts display processing shown in the flowchart of FIG. In the flowchart of FIG. 15, steps having the same step numbers as in FIG. 10 perform the same processing as the processing in the flowchart of FIG.

  If it is determined in step S104 that the CPU 101 is similar (step S104; Yes), the CPU 101 determines whether or not the position acquired from the acquisition unit 205 is within a predetermined range (step S201). When the CPU 101 determines that the position acquired from the acquisition unit 205 is within a predetermined range (step S201; Yes), the second generation unit 202 sets the position or size of the second object (step S201). S202). For example, as illustrated in FIG. 11B, the second generation unit 202 has the same size and shape as the target object MO3, and the second object SO3 having a different color is displayed at the currently displayed position ( P2_2 is generated at a position (P2_3) further shifted from FIG. 8B). On the other hand, when the CPU 101 does not determine that the position acquired from the acquisition unit 205 is within the predetermined range (step S201; No), the second generation unit 202, as illustrated in FIG. A second object SO3 having a color different from that of the first object and having the same size and shape as the first object is generated at the position (P2_2) acquired by the acquisition unit 205.

  In addition, the 2nd production | generation part 202 may change both the position and magnitude | size of a 2nd object, when the acquired position exists in a predetermined range (step S201; Yes). That is, when the acquired position is within a predetermined range, the second generation unit 202 generates a second object at a position further shifted from the acquired position, and reduces the second object to a smaller size. Set (FIG. 16). By setting in this way, it is possible to provide a visual effect that makes the first object float more.

  According to the present embodiment, it is possible to impart a visual effect such that there is unevenness in a predetermined range, thereby making it easier to visually recognize an object in the predetermined range.

  According to the present invention, it is possible to provide a display device, a display method, and a program that are suitable for facilitating visual recognition of an object to be noticed when the transmissive display is used on another display.
