DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereo image display device, a stereo image display method, and a storage medium, and more particularly to a stereo image display device that allows a user to display a stereo image without using special glasses such as polarized glasses and liquid crystal shutter glasses. The present invention relates to a stereo image display device, a stereo image display method, and a storage medium suitable for observation as a stereoscopic image.

2. Description of the Related Art Conventionally, a stereoscopic image display (3D display) of a parallax barrier type and a 3D display of a lenticular lens type have been known as direct-view type stereo image display devices that do not require the use of special glasses.

[0003] These 3D displays use the optical properties of a parallax barrier and a lenticular lens to separate the left-eye image and the right-eye image displayed on the image display panel into left and right images, and vertically separate them from the display. It is designed so that the user can observe a stereoscopic image at a position (appropriate viewing position) at a certain distance from the camera. If the user observes the display at a position distant from the appropriate viewing position, a stereoscopic image cannot be normally observed.

The following two methods are known as methods for enabling a user to always observe a display from an appropriate viewing position.

One method is to detect a user's movement using a sensor, a camera, or the like, and to move the suitable viewing position following the user's movement. In this method, the suitable viewing position can be moved right and left by mechanically or electrically controlling the parallax barrier or the lenticular lens. However, since it is difficult to move the suitable viewing position back and forth, it cannot follow the user's movement in the front-back direction. In order to realize this method, the mechanism of the apparatus becomes complicated, and the manufacturing cost of the apparatus increases.

[0006] Another method is a method of displaying an image whose appearance is clearly changed depending on whether or not the user is at an appropriate viewing position. According to this method, when the user deviates from the optimum viewing position, it is possible to recognize that the user has deviated from the optimum viewing position by changing the appearance of the image, so that the user can return to the optimum viewing position by moving.

This is a file for expressing a sequence image, and does not itself include image data. In the SSI file, the left-eye image file name and the right-eye image file name (stereo pair file name) included in the sequence image are stored in order, and a predetermined control character string is described. I have.

The two file names written on each line in the description example of FIG. 5A are an image file name for the left eye and an image file name for the right eye, respectively. The character string “<P>” in the figure is a control character for moving the position on the two-dimensional array of the sequence image one position to the lower side and to the leftmost position. FIG. 5B shows a two-dimensional array of sequence images corresponding to the description of the SSI file in FIG. FIG.
In (b), a large square represents a two-dimensional array of sequence images, and a small square represents each element of the two-dimensional array, that is, a stereo image or a stereo pair file name. The position of each element of the two-dimensional array is described inside a small square in the format of (X coordinate, Y coordinate).

The SSI file processing unit 401 shown in FIG.
Reads out each line of the SSI file in order and sequentially stores the stereo pair file names in a two-dimensional array prepared in advance. At this time, the storage position starts from the origin (0, 0) of the two-dimensional array, moves sequentially to the right,
When the control character string "<P>" appears in the file, it moves down by one and to the left.
In this way, the SSI file processing unit 401 stores the stereo pair file name of the series image described in the SSI file in association with the position on the two-dimensional array.

Is input, and if necessary, change the numerical value of “left / right space” and press the “OK” button at the end to automatically change the “Start (T)” and “End (B)” character strings. A rotation sequence file name is created automatically, a plurality of stereo pair file names are automatically created from the rotation sequence file name and the numerical value of “left and right space”, and the SSI file specified by the “storage destination SSI file name” After that, the "Open Rotation Series" dialog box is closed.

Further, when the SSI file is created normally, the SSI file is automatically opened, the stereo pair file described at the beginning of the SSI file is read out, and after being synthesized, a stereo image is displayed. You.

The "start (T)" character string and the "end (B)"
The character string must be a file name indicating any one of a plurality of files constituting a rotation sequence file (a set of files satisfying the above four conditions (1) to (4)). (T), a numerical value (Nt1) indicated by a numeric character string corresponding to the horizontal dimension of the character string, a numerical value (Nb1) indicated by a numeric character string corresponding to the horizontal dimension of the “tail (B)” character string, and Numerical value of "left and right gap"
Must satisfy the relationship of Expression (1) and Expression (2).

(Nt1) <(Nb1) (1) (Nt1) + (Nd) ≦ (Nb1) (2) If the condition of Expression (1) is satisfied, “head (T)” By sequentially replacing the numeric character string portion corresponding to the horizontal dimension of the character string or the "tail (B)" character string from a character string of a numerical value obtained by continuously changing from (Nt1) to (Nb1) , A rotation sequence file name can be automatically created.

Further, when the condition of the equation (2) is satisfied, the numerical values indicated by the numerical character strings corresponding to the horizontal dimensions of the file name of the left-eye image are (Nt1), (Nt1 + 1),
.. Are changed in the order of (Nb1−Nd), and the numerical values indicated by the numerical character strings corresponding to the horizontal dimensions of the file name of the right-eye image are (Nt1 + Nd), (Nt1 + Nd + 1),.
By changing in the order of (Nb1), a plurality of stereo pair file names can be automatically created.

Next, a case where a two-dimensional rotation sequence is opened will be described with reference to FIG. However, the process for opening a two-dimensional rotation sequence is only a process of adding a "column" (vertical dimension of a two-dimensional array) to the process for opening a one-dimensional rotation sequence. Now, only matters relating to the additional processing will be described.

In the figure, when the user checks the “column” check box, a character string can be input to the “end (E)” of the “column”, and the character string is located on the right side of the “end (E)”. It becomes possible to press the "reference (G)" button. The “reference (G) button” will be described later. Here, the user inputs a character string in the “head (T)”, “end (B)”, “end (E)”, and “storage destination SSI file name”. ”And press the“ OK ”button at the end to automatically rotate the file from the“ Start (T) ”,“ End (B) ”and“ End (E) ”character strings. Are created, and a plurality of stereo pair file names are automatically created from the rotation series file name and the numerical value of “left and right space”.
After being described in the SSI file specified by "SI file name", the "Open Rotation Series" dialog box is closed.

The "head (T)" character string and the "end (B)"
The character string must be a file name indicating any one of a plurality of files constituting the first row of the two-dimensional array indicated by the rotation sequence file, and the condition of the above formulas (1) and (2) Must be satisfied.

The "start (T)" character string and the "end (E)"
The character string must be a file name indicating any one of a plurality of files constituting the first column of the two-dimensional array indicated by the rotation sequence file, and the vertical direction of the “head (T)” character string Numerical value (Nt2) indicated by numeric character string corresponding to dimension
And the numerical value (Ne2) indicated by the numeric character string corresponding to the vertical dimension of the “end (E)” character string, the relationship of Expression (3) must be established.

(Nt 2) ≦ (Ne 2) (3) As described above, when the condition of Expression (1) is satisfied, the rotation sequence file name for the horizontal dimension can be automatically created. . When the condition of Expression (3) is satisfied, the numeric character string portion corresponding to the vertical dimension of the “head (T)” character string or the “end (E)” character string is represented by (Nt
By sequentially replacing numerical values that are continuously changed from 2) to (Ne2) with character strings, a rotation sequence file name for the vertical dimension can be automatically created. Therefore, when the conditions of Expressions (1) and (3) are satisfied, the rotation sequence file names for both the horizontal and vertical dimensions can be automatically created.

Since the expression (2) has a meaning only in the horizontal dimension, the two-dimensional case is obtained from the rotation sequence file name and the numerical value of “left / right space” as in the case of the one-dimensional case. Multiple stereo pair file names can be created automatically.

When the "reference (F)" button on the right side of "top (T)" is pressed in the "open rotation series" dialog box, a "reference image file name" dialog box is displayed.

FIGS. 28 and 29 are explanatory diagrams showing the “switching rule” dialog box. FIG. 28 shows items to be set when the virtual two-dimensional array of the series images has no vertical dimension, and FIG. 29 shows the virtual two-dimensional array of the series images having the vertical dimension. Items to be set in the case are shown. In FIG. 28, when the “column setting” check box is checked, the display of the “switching rule” dialog box changes as shown in FIG.

First, referring to FIG. 28, the virtual two-dimensional array of the sequence images is shifted from the origin (0, 0) to the right end (4, 4).
When there are array elements up to 0) (in the case of one-dimensional array)
Will be described as an example. In FIG. 28, when the user selects or inputs the following items and presses the “OK” button, after the “switching rule” dialog box is closed,
The switching rule becomes effective. “Repeat mode” is a mode in which the currently displayed stereo image is located at the extreme end (right end or origin) of the virtual one-dimensional array of the series images, When the switching for switching the position (switching to the right or switching to the left) is performed, this is an item for the user to determine in advance which position of the image in the one-dimensional array should be displayed.

When the "ON" radio button is selected as the "repeat mode", the position on the one-dimensional array is switched as follows. That is, if the user tries to move the position to the right while the current position is at the right end (4, 0), the next position becomes the origin (0, 0), and the current position is at the origin (0, 0). , The next position is at the right end (4, 0).

When the "OFF" radio button is selected as the "repeat mode", the position on the one-dimensional array is switched as follows. That is, the current position is at the right end (4, 0).
If you try to move the position to the right while in, the next position stays at the right end (4, 0) and the current position is the origin (0,
If the position is to be moved to the left while at the position (0), the position remains at the origin (0,0).

In the “line” edit box of “skip interval”, an integer value of 0 or more and 9 or less can be input. When a value Nx is input to the “row” edit box of the “skip interval”, when the horizontal position of the virtual two-dimensional array (or one-dimensional array) of the series images is switched,
Instead of moving one by one, it moves horizontally by (Nx + 1).

Next, referring to FIG. 29 and FIG.
Similar to (b), a case where the virtual two-dimensional array of the series images has array elements from the origin (0, 0) to the lower right end (4, 2) will be described as an example. In FIG. 29, when the user selects or inputs the following items and presses the “OK” button, the “switching rule” dialog box is closed and the switching rule becomes valid. “Repeat mode” and “repeat unit” are used when the currently displayed stereo image is located at the extreme end (left end, right end, top end or bottom end) of a virtual two-dimensional array of sequence images. Switching to move the position on the two-dimensional array in a direction exceeding
Switch right, switch up or switch down)
Next, this item is for the user to determine in advance which image on the two-dimensional array should be displayed.

When the "ON" radio button is selected as the "repeat mode" and the "whole series" radio button is selected as the "repeat unit", the positions on the two-dimensional array are switched as follows. That is, if the position is to be moved right or down while the current position is at the lower right end (4, 2), the next position becomes the origin (0, 0). If the current position is at the origin (0,0) and the position is to be moved left or up, the next position is the lower right end (4,2). If you try to move the position to the right when the current position is at the right end (4,0), the next position will be one lower left end (0,0).
1). If the position is to be moved to the left when the current position is at the left end (0, 1), the next position is the upper right end (4, 0). If the user attempts to move the position downward while the current position is at the lower end (1, 2), the next position is the upper right position (2, 0) to the right. The current position is at the top (2,
If the position is to be moved upward when the position is at (0), the next position is one lower left end (1, 2).

The “ON” radio button is selected as the “repeat mode”, and “Same line /
When the "column" radio button is selected, the position on the two-dimensional array is switched as follows. That is, if the position is to be moved to the right when the current position is at the right end (4, 0), the next position becomes the origin (0, 0) which is the left end of the same row.

FIGS. 47, 48 and 49 are explanatory diagrams showing a method of displaying a stereo image on the main window in the stereo image display program. In these figures, all toolbars are hidden. In the following description, it is assumed that the origin is the upper left corner of the desktop window (the entire display surface of the display), the XY coordinates are such that the positive direction of the X axis is rightward and the positive direction of the Y axis is downward. At this time, the X coordinate of the upper left corner of the main window is X
The m and Y coordinates are Ym, the X coordinate of the upper left corner of the stereo image displayed on the main window is Xs, and the Y coordinate is Ys. In addition, the main window size is set to width Wm and height H.
m, and the display size of the stereo image is width Ws and height Hs
And

In the following description, it is assumed that the direct-view display 102 is designed to display an image for the left eye on even lines and an image for the right eye on odd lines. Further, the stereo image data processing unit 30 shown in FIG.
No. 6 assumes that a stereo image is created by inserting a left-eye image into an even-numbered line and inserting a right-eye image into an odd-numbered line.

FIG. 47 is an explanatory diagram showing a display state of a stereo image when the display size of the stereo image is smaller than the main window. When the display size of the stereo image is smaller than the main window size, the stereo image is arranged at the center of the main window. At this time, the stereo image display program calculates the X coordinate of the upper left corner of the stereo image according to Expression (4) and the Y coordinate according to Expressions (5) and (6).

Xs = (Wm−Ws) / 2 + Xm (4) Ys ′ = (Hm−Hs) / 2 + Ym (5) Ys = Ys ′ + (Ys ′% 2) (6) However, in Expression (6), (Ys '% 2) means "the remainder when Ys' is divided by 2" in the integer operation, and is either the value 0 or the value 1. By performing such a calculation, the even lines of the stereo image are always displayed on the even lines of the desktop window. Therefore, even if the display position of the main window moves up and down, the left and right of the stereo image are inverted. You can't see it.

FIGS. 48 and 49 are explanatory diagrams showing a display state of a stereo image when the display size of the stereo image is larger than the main window size. When the display size of the stereo image is larger than the main window size, in the initial state, the stereo image is arranged so that the center of the stereo image is located at the center of the main window. At this time, the stereo image display program also executes the X in the upper left corner of the stereo image.
The coordinates are calculated according to equation (4), and the Y coordinate is calculated according to equations (5) and (6). However, when the display size of the stereo image is larger than the desktop window size, Ys ′ in Expression (5) is a negative value, and (Ys ′% 2) in Expression (6) is either 0 or −1. Ys in Expression (6) is also a negative value.

In FIG. 48, the mouse cursor is moved to an arbitrary position on the stereo image, and the mouse 10 is moved to that position.
When you click the left button of No.4, as shown in FIG.
The display position of the stereo image is changed so that the clicked position is at the center of the main window. At this time, the position of the mouse cursor also moves simultaneously with the movement of the display position of the stereo image. At this time, the stereo image display program recalculates the display position of the stereo image and the position of the mouse cursor in the following procedure.

The X coordinate of the mouse cursor when the left button of the mouse 104 is clicked is Xc, the Y coordinate is Yc, the movement amount of the stereo image display position in the X direction is δx,
The amount of movement in the Y direction is δy. At this time, provisional values of δx and δy can be calculated according to Equations (7) and (8).

Δx ′ = Wm / 2 + Xm−Xc (7) δy ′ = Hm / 2 + Ym−Yc (8) Further, the X coordinate of the display position of the stereo image after the movement is Xn.
Assuming that the s and Y coordinates are Yns, provisional values of Xns and Yns can be calculated according to Equations (7) and (8).

Xns ′ = Xs + δx ′ (9) Yns ′ = Ys + δy ′ (10) Here, when Xns ′ is larger than Xm, Expression (11)
Xns' is recalculated according to
-Ws), Xn according to equation (12)
Recalculate s'. If Yns ′ is larger than Ym, Yns ′ is recalculated according to equation (13), and Yns ′ is calculated again.
When s ′ is smaller than (Ym + Hm−Hs), the expression (1)
Recalculate Xns' according to 4).

According to these calculations, although the display size of the stereo image is larger than the main window size, a part of the main window becomes blank because the moving amount of the stereo image is too large (only the background color is displayed). Situation can be avoided.

Xns '= Xm (11) Xns' = Xm + Wm-Ws (12) Yns '= Ym (13) Yns' = Ym + Hm-Hs (14) Is performed, the display position of the stereo image after the movement can be determined according to Expressions (15) and (16).

Xns = Xns ′ (15) Yns = Yns ′ + (Yns ′% 2) (16) The movement amount of the display position of the stereo image is calculated according to Expressions (17) and (18). Can be calculated.

Δx = Xns−Xs (17) δy = Yns−Ys (18) The X coordinate of the mouse cursor after moving is Xnc, and the Y coordinate is Y.
Assuming that nc, Xnc and Ync can be calculated according to equations (19) and (20).

Xnc = Xc + δx (19) Ync = Yc + δy (20) By using the above formula, the clicked position on the stereo image is moved to the center of the main window, and The position of the mouse cursor can be moved in accordance with the movement of the display position. Normally, the user looks at the mouse cursor when clicking the mouse, so that when the mouse cursor moves in accordance with the display position of the stereo image, the movement of the display position of the stereo image can be intuitively understood.

In the description of FIGS. 47 to 49, the X coordinate calculation formula and the Y coordinate calculation formula are described side by side for easy understanding. However, the X coordinate calculation and the Y coordinate calculation are completely independent. are doing. Therefore, even if the width of the stereo image is smaller than the width of the main window, but the height of the stereo image is larger than the height of the main window, or the relationship between the width and the height is reversed, FIG. All cases can be dealt with by appropriately combining the description about the X coordinate and the description about the Y coordinate in FIG.
