TECHNICAL FIELD OF THE INVENTION
The present invention provides a stereoscopic image editing apparatus that generates a stereoscopic image by displaying two or more planar images shifted left and right on an editing screen, enables the stereoscopic image to be edited, and a stereoscopic image editing device. About the program.
[0002]
[Prior art]
In commercial transactions using the Internet, so-called E-commerce, it is very effective to stereoscopically view a product on a screen because the product cannot be actually picked up. However, in order to provide various contents as a stereoscopic image on the screen of a personal computer, a device that can quickly and easily edit a planar image acquired by a digital camera or the like is required.
[0003]
Therefore, conventionally, a shooting adapter for easily obtaining a right and left plane image necessary for generating a stereoscopic image with a digital camera or the like, and an editing screen for determining whether the obtained image is a right image or a left image. There has been proposed a stereoscopic image editing apparatus having a function that can be easily identified above (for example, see Patent Document 1).
[0004]
In addition, two plane images to which depth values (also referred to as “amount of deviation” and “height”) corresponding to binocular parallax and parameters such as a sense of transparency are added from one plane image are created. A stereoscopic image editing apparatus that generates a stereoscopic image from two planar images has also been proposed (for example, see Patent Document 2).

[Problems to be solved by the invention]
However, the stereoscopic image editing apparatus shown in the above prior art is not sufficient as an editing function, and a stereoscopic image can be easily created by reading a planar image captured by a digital camera or the like, and the editing work can be easily performed. In order to be able to do it quickly, further improvements were required.
[0008]
SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a stereoscopic image editing apparatus that can easily generate a stereoscopic image from a planar image and can easily and quickly edit the stereoscopic image.
[0009]
[Means for Solving the Problems]
The stereoscopic image editing apparatus according to the present invention has the following configuration.
[0010]
(1) In a stereoscopic image editing apparatus in which two or more plane images shifted left and right are displayed on an editing screen to generate a stereoscopic image, and the stereoscopic image can be edited on the editing screen,
Moving image setting means for setting only a specific image in the plane image as a moving image movable on the screen,
When an arbitrary coordinate position is designated by a pointing device on the editing screen, a predetermined area is formed based on the position, and within this predetermined area, an image editing that displays only the moving image existing in the area And processing means.
[0011]
The stereoscopic image according to the present invention is typically formed by displacing left and right LR images (hereinafter, L images) of a left image (hereinafter, L images) and left and right images (hereinafter, R images). At this time, the LR images need to be parallel to each other in the horizontal direction (parallelism), and need not be mutually rotated (non-rotational). The magnifications must not be different. Therefore, in order to obtain an appropriate LR plane image, it is preferable to use a stereo image capturing adapter or the like as disclosed in JP-A-2002-125246. However, in practice, the LR image displayed on the editing screen may not satisfy the above conditions (parallelism, non-rotational property, etc.). According to the present invention, in such a case, the position of the LR image can be easily adjusted (image editing) on the editing screen.
[0012]
That is, one of the LR images on the editing screen is fixed, the other is set as a movable image, and when an arbitrary coordinate position is designated by a pointing device (mouse, trackball, or the like), the position is changed. Attention is paid to a predetermined area serving as a reference, and control is performed so that only moving images existing in the predetermined area are displayed. In this case, if the L image is a fixed image and the R image is a moving image, when the user clicks the coordinate position of the R image on the edit screen to move the R image, the clicked coordinate position becomes If the position of the R image is correctly indicated, only the R image within a predetermined area based on the position is displayed. Therefore, at this time, the designated coordinate position is correct, and if the pointing device is dragged thereafter, the R image moves according to the drag.
[0013]
On the other hand, if the coordinate position where the user clicks the pointing device to specify the R image is actually an L image, the L image is not displayed in a predetermined area based on the position. Therefore, at this time, the user can easily know that the image at the designated position is not actually the R image.
[0014]
That is, if the image specified by the mouse or the like with the mouse or the like as an R image that is a moving image is actually an L image, the image at the clicked position is not displayed. You can know. Conversely, if the image is displayed at the specified position, it can be known that the R image has been correctly specified. As described above, in order to display a moving image in a predetermined area based on the specified coordinate position, the user can easily recognize whether the specified image is an incorrect L image or a correct R image. Can be.
[0015]
The present invention is also applicable to a case where three or more planar images are used to generate a stereoscopic image. For example, when three plane images are used, the L image is a fixed image, the remaining two images are an R1 image and an R2 image, and the R1 image and the R2 image are moving images. At this time, when the L image is designated, only the R1 image and the R2 image within a predetermined area based on the designated coordinate position are displayed. At this time, the manner of displaying the R1 image and the R2 image may be changed.
[0016]
(2) In a stereoscopic image editing apparatus that generates a stereoscopic image by displaying two or more planar images shifted to the left and right on an edit screen and enables the stereoscopic image to be edited on the edit screen,
When saving the stereoscopic image file, the stereoscopic image is stored in a lossless compression format when the image is a clear image such as a character image, and is stored in an irreversible compression format when the image is any other image. A storage means is provided.
[0017]
In addition, in a stereoscopic image editing program that generates two-dimensional images by displaying two or more two-dimensional images shifted to the left and right on an editing screen and enables the three-dimensional images to be edited on the editing screen,
When saving the stereoscopic image file, the stereoscopic image is stored in a lossless compression format when the image is a clear image such as a character image, and is stored in an irreversible compression format when the image is any other image. The storage function is realized by a computer.
[0018]
According to the present invention, among the stereoscopic images, an image having a clear outline such as a character image is stored in a lossless compression format, and an image captured by a digital camera or the like whose outline is not clear is stored in an irreversible compression format. . The reversible compression format is a compression format in which the image is not deteriorated when the file is stored. For example, there is a PNG format used for displaying images on the Web. On the other hand, the irreversible compression format is a format in which an image deteriorates when a file is stored. The JPEG format is an example of a typical lossy compression format. In a stereoscopic image editing apparatus, there is a case where a stereoscopic image based on a character image input from a keyboard or the like is pasted on a stereoscopic image based on a two-dimensional image captured by a digital camera or the like to edit the image. When saving in a compressed format, the degree of image loss differs between a character image with a clear outline and an image without a clear outline, so the next time it is displayed on the editing screen, there is a clear difference between the two. And may be unnatural on the whole. Specifically, an image having a clear outline such as a character image has an inappropriately blurred appearance with respect to a base background image.
[0019]
Therefore, in the present invention, when the stereoscopic image is an image having a clear outline such as a character image, the image is stored in a lossless compression format so that no image is lost, and when the image is other than the base image, the image is irreversible. Save the compressed format. By doing so, the above-mentioned disadvantages can be solved, and the file size can be prevented from becoming larger than when all images are stored in a lossless compression format. Since the file storage unit automatically selects these formats according to the type of the image, the user does not need to worry about the compression format for each image, and the operability does not deteriorate. .
[0020]
(3) In a stereoscopic image editing apparatus that generates two-dimensional images by displaying two or more two-dimensional images shifted to the left and right on an edit screen and enables the three-dimensional images to be edited on the edit screen,
When another stereoscopic image is pasted on the stereoscopic image on the edit screen, each stereoscopic image is displayed as a layer structure, and a layer screen displaying a thumbnail image for each layer is displayed. When an arbitrary thumbnail image is selected on the screen, a stereoscopic image corresponding to the selected image is selected on the editing screen, and image editing means for enabling the editing of the stereoscopic image on the editing screen is provided. Features.
[0021]
In addition, in a stereoscopic image editing program that generates two-dimensional images by displaying two or more two-dimensional images shifted to the left and right on an editing screen and enables the three-dimensional images to be edited on the editing screen,
When another stereoscopic image is pasted on the stereoscopic image on the edit screen, each stereoscopic image is displayed as a layer structure, and a layer screen displaying a thumbnail image for each layer is displayed. When an arbitrary thumbnail image is selected on the screen, a stereoscopic image corresponding to the selected image is selected on the editing screen, and the computer realizes an image editing function of enabling the stereoscopic image to be edited on the editing screen. It is characterized by the following.
[0022]
In the present invention, a layer window is arranged together with an edited image window on a screen, and each stereoscopic image displayed on the edited image window (edit screen) has a layer structure. Then, a thumbnail image for each layer is displayed in the layer window. When an arbitrary thumbnail image is selected in the layer window, a stereoscopic image corresponding to that image is selected in the edited image window. For example, only the stereoscopic image corresponding to the selected thumbnail image is highlighted and the other stereoscopic images are darkened. In this state, a large number of parameters such as a height parameter (a parameter indicating the degree of left / right deviation), a transparency parameter, a pasting position parameter, and a parameter indicating a degree of time axis change of each parameter with respect to the selected stereoscopic image can be edited. Become like To edit these parameters, a pop-up window (dialog) for editing parameters of the selected image may be displayed at the time of selecting a thumbnail image.
[0023]
As described above, when a plurality of stereoscopic images are displayed on the editing screen, these stereoscopic images are displayed as a layer structure, and each stereoscopic image is selectively displayed on the editing screen for each layer, so that each stereoscopic image is displayed. Editing of parameters associated with the image is facilitated.
[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a functional block diagram of a stereoscopic image editing apparatus according to the present invention. This stereoscopic image editing apparatus is usually composed of a personal computer. Therefore, functions necessary for performing the editing process are provided by the stereoscopic image editing program.
[0025]
In FIG. 1, digital cameras 1 and 2 capture an L image (left plane image) and an R image (right plane image), respectively. In this figure, two digital cameras 1 and 2 are shown to capture an L image and an R image, respectively. However, one digital camera is used to capture an L image and an R image at different times. You may make it. Further, the L image and the R image may be simultaneously captured by one multi-lens camera.
[0026]
The L image and the R image are input to the image input unit 3 and passed to the stereoscopic image editing unit 4 directly or indirectly via a file storage unit. Specifically, it is input to the stereoscopic view format setting section 42 in the stereoscopic image editing section 4. The stereoscopic view format setting section 42 is a section for setting the stereoscopic view format of the LR image from the image input section 3. Stereoscopic formats include a naked-eye parallel method, a naked-eye crossing method, a red-blue two-color glasses three-dimensional method, a liquid crystal glasses three-dimensional method, and the like, and image processing is performed according to these formats. Note that the file input processing unit 40 in the stereoscopic image editing unit 4 controls the image input unit 3.
[0027]
The file storage processing unit 41 stores a stereoscopic image file stored in the image memory 5 in the image file unit 6 and reads a stereoscopic image file stored in the image file unit 6 into the image memory 5. Perform processing.
[0028]
The LR image automatic creation unit 43 of the stereoscopic image editing unit 4 automatically creates an LR image for an image having a clear contour such as a character image and stores the LR image in the image memory 5 as a stereoscopic image. The character information from the character input unit 8 is input to the LR image automatic creation unit 43. In addition, a character input from the keyboard 7 is input to the character input unit 8. It is also possible to input an image from the image input unit 3 to the LR image automatic creation unit 43 by setting. The method of automatically creating an LR image in the LR image movement creating unit 43 is disclosed in, for example, JP-A-2002-123842. As an example of a method of automatically creating an LR image, another image is created for a character input from the character input unit 8, and these two character images are defined as an L image and an R image. The parameter of the height (shift amount) is automatically set according to values such as hue, saturation, and lightness.
[0029]
The image editing processing unit 44 includes an LR image determining unit 440 and a parameter setting processing unit 441. The designated coordinate position data from the mouse input unit 9 is input to the LR image determination unit 440. A mouse 10 is connected to the mouse input unit 9. The LR image determination unit 440 sets the L image as a fixed image that cannot be moved on the editing screen, sets the R image as a moving image that can be moved on the editing screen by default, and receives the designated coordinate position data from the mouse input unit 9. When input, a process of forming a predetermined area based on the position, a process of displaying only an R image (moving image) existing in the area in the predetermined area, and the like are performed.
[0030]
The parameter setting processing unit 441 in the image editing processing unit 44 sets parameters such as height, transparency, pasting position, and time axis change degree of each parameter for each stereoscopic image.
[0031]
A layer window processing unit 442 in the image editing processing unit 44 displays a layer window separately from the editing window on the screen, creates and sets a thumbnail image for each layer, or sets an arbitrary image on the layer screen. When a thumbnail image is selected, only the stereoscopic image corresponding to that image is displayed on the editing window, and the other stereoscopic images are darkened. Further, when a setting button on the layer window is operated, processing such as displaying a popup dialog for parameter editing is performed.
[0032]
The image memory 5 stores a stereoscopic image composed of LR images stored in the JPEG format and parameters in pairs. When a plurality of stereoscopic images are displayed on the editing window, image data for each stereoscopic image is stored in the image memory. Specifically, each time the LR image is input from the image input unit 3, the LR image passes through the stereoscopic format setting unit 42, and is sequentially stored as a stereoscopic image together with parameters. Each time character data is input from the character input unit 8, the data passes through the LR image automatic creation unit 43 and is stored as a stereoscopic image together with parameters. The image data on the image memory 5 is developed on the graphic memory 10 according to the parameter information and displayed on the monitor screen.
[0033]
Hereinafter, each function will be described.
[0034]
(A) Function of LR image determination unit 440
In FIG. 1, when two digital cameras 1 and 2 capture an L image and an R image, one digital camera captures an L image and an R image, or one multiview camera captures an L image and an R image. When an image is captured, in order to display the image as a stereoscopic image on the editing window, the LR images are matched on a horizontal line, and the images are not rotated, and the magnifications are the same. It is necessary to set the image as follows. That is, in the LR image, it is necessary that the mutual images match at least three or more pixels. Therefore, actually, it may be necessary to operate the LR image on the editing window using a mouse. In the present embodiment, when the data of the coordinate position specified by the mouse click (designated coordinate position data) is input from the mouse input unit 9 to the LR image determination unit 440, a predetermined area is formed based on the position. Also, as default, the L image is set as a fixed image that does not move on the editing window, and the R image is set as a moving image that can move on the editing window. Further, within the predetermined area, only the moving image existing in the area, that is, the R image is displayed. Therefore, the fixed image existing in this area is not displayed.
[0035]
FIG. 2 is a diagram for explaining a function of the LR image determination unit 440. Now, it is assumed that the L image and the R image when the image input from the image input unit 3 is converted into a stereoscopic image are shown in FIG. 2A and FIG. 2B, respectively. This is displayed on the editing window W1 as a stereoscopic image. In this state, if the user designates “L” displayed on the left side by clicking the mouse as shown in 1- (1) in FIG. 2, a predetermined area P shown in the figure is formed, and 1- (2) As shown in the figure, within the predetermined area P, only the R image existing in the area P is displayed, and "L" is not displayed. Therefore, the user can recognize that the image at the position designated by the mouse click is the L image.
[0036]
Also, as shown in 2- (1), when "R" is designated by clicking the mouse, a predetermined area P is formed, and only the R image in this area P, that is, only the "R" character is displayed. Since the coordinate position where the mouse is clicked matches the character of "R", the user can know that the image at the position specified by the mouse click was correctly an R image.
[0037]
In this way, it is possible to easily determine whether the image specified by the mouse is an L image or an R image in a state where the L image and the R image are displayed overlapping on the editing window W1. In this embodiment, since the L image is set as the fixed image and the R image is set as the moving image by default, if the user drags after specifying the R image with a mouse click, the R image moves in the direction of the mouse drag.
[0038]
The display in the edit window W1 is performed by selecting “pair display” in the pop-up window shown in FIG. 2 to specify a stereoscopic composite display format, whereby a stereoscopic image is displayed on the edit window W1. Is done.
[0039]
Further, as described above, the L image is a fixed image and the R image is a moving image by default, but it is also possible to set the reverse.
[0040]
FIG. 3 shows a flowchart of a program for realizing the function of the LR image determination unit 440.
[0041]
When an image (stereoscopic image) on the editing window W1 is designated by the mouse 10 (ST1), the LR image is displayed as a stereoscopic image on the editing window W1 (ST2). At this time, parameters such as height and transparency are referred to, image processing is performed according to the parameters, and displayed.
[0042]
When an image on the edit window W1 is designated by the mouse 10 (ST3), a predetermined area around the designated coordinate position is formed, and only the R image is displayed in the predetermined area (ST4). At this time, the displayed R image may be made to stand out more than the surrounding images by adjusting the saturation, brightness, and the like. If the mouse is dragged in this state (ST5), the R image is moved according to the drag, and the moved R image and L image are synthesized and displayed again when the mouse is released (ST6). In ST6, when the mouse is released, first, the composite display in the predetermined area is performed, and then, the composite display is performed on all the images in the edit window W1.
[0043]
Through the above processing, when the mouse is clicked, the user can immediately determine whether the image specified by the mouse click is an R image or an L image. In the above case, since only the R image is set as the moving image, if the image at the coordinate position where the mouse is clicked is displayed when the mouse is clicked, the user simply drags the mouse because the specified image is the R image. By doing so, the R image can be moved by an arbitrary amount. On the other hand, if the image at the position where the mouse is clicked is the L image, the surrounding L images including that position are not displayed, and the user immediately determines that the image specified by the mouse is not a movable R image. be able to. In this case, the operation is erroneous, and the user again attempts to specify the R image by clicking the mouse at another place.
[0044]
With the above functions, the user can easily determine the LR image regardless of the size of the image, and can adjust the LR image without interrupting the thinking.
[0045]
(B) Function of file storage processing unit 41
In FIG. 1, LR images are automatically created by inputting character data from a character input unit 8 to an LR image automatic creation unit 43. The character data is captured by digital cameras 1, 2 and the like. Unlike an image, the outline of the image is very clear. Therefore, when both the image having a clear contour such as the character image and the image having an unclear contour captured by the digital cameras 1 and 2 are compressed by a general irreversible compression method and stored in the file storage unit 6, The next time they are reproduced, the appearance will be unnatural. FIG. 4 shows this state. Looking at the enlarged portion of the stereoscopic character image at the character position of the “viewer” in the entire image, the image saved by the irreversible compression method indicated by 2 (3D composite image and left and right images (2- ▲ 1 ▼, 2- (Including (2))), the image is missing again, and the image stored in the lossless compression method indicated by 1 (3D composite image and left and right images (1- (1), 1- (2)) On the other hand, it looks unnatural.
[0046]
Therefore, in the present embodiment, an image having a clear outline such as a character image is compressed by a lossless compression method and saved in a file, and the other images, that is, the outlines of the images captured by the digital cameras 1, 2 and the like are displayed. Unclear images are stored in a file using a lossy compression method. An image having the same property as a digital camera captured image such as a landscape image or a person image acquired from the Web or the like via the file input processing unit 40 is similarly treated. In the present embodiment, specifically, the JPEG method is adopted for the lossy compression method, and the PNG method is adopted for the lossless compression method.
[0047]
These compression methods are set in the parameter section attached to each image data. The file storage processing unit 41 determines whether to store the data in the file storage unit 6 in the JPEG format or the PNG compression format by checking the compression format of the parameter portion.
[0048]
Note that examples of the image having a clear outline include a logo image, a vector data image, and the like in addition to the character image described above.
[0049]
FIG. 5 is a flowchart of a program for realizing a storage function among the functions of the file storage processing unit 41.
[0050]
When the file saving is specified, the image compression method parameter is referred to for each stereoscopic image in the editing window W1 (ST10). Then, for each stereoscopic image, it is determined whether or not the image is a contour holding image (ST11). If the image is a contour holding image, PNG compression is performed and stored (ST12). If the image is not a contour holding image, JPEG compression is performed. And save (ST13).
[0051]
By the above processing, even if editing is repeated, the stereoscopic effect is not lost when viewing a stereoscopic image, and the irreversible compression method such as the JPEG method has a high compression rate, so that the file size is reduced. It is possible to reduce the size, to effectively use the resources of the memory and the storage device, and to improve the transmission efficiency. Further, since the above operation is automatically performed, no burden is imposed on the user.
[0052]
(C) Layer window processing and parameter setting processing
The layer window processing unit 442 automatically registers each stereoscopic image stored in the image memory 5 as a layer. As shown in FIG. 6, a layer window W2 is set on the display screen separately from the editing window W1. FIG. 6 shows a positional relationship between the editing window W1 and the layer window W2 arranged in the screen.
[0053]
In this layer window W2, thumbnail images of each stereoscopic image are displayed. When an arbitrary thumbnail image is selected, a stereoscopic image corresponding to the selected thumbnail image is selected in the editing window W1. Specifically, on the editing window W1, the selected stereoscopic image is activated to be editable, and the other stereoscopic images are displayed dark.
[0054]
In the layer window W2, the thumbnail images are automatically rearranged and displayed in the order of the height (shift amount) parameter. In the rearrangement, the height is a default. Instead of the height, parameters such as a pasting position and transparency can be set as parameters for rearrangement.
[0055]
In FIG. 6, a stereoscopic image such as a character image or a logo image is set in the layer window W2 in addition to a plurality of normal stereoscopic images. Characters can be created by opening a new character creation window shown at W3. The logo can be selected by opening a new logo image creation window shown in W4. To paste the logo image selected in the new logo image creation window of W4 on the edit window W1, select "Paste Logo" (not shown) in the edit menu.
[0056]
FIG. 7 illustrates an editing method using the layer window W2. In the layer window W2, buttons for setting various parameters are arranged at positions next to the thumbnail images together with a layer screen for displaying thumbnail images of the respective stereoscopic images. By operating this setting button, a layer setting dialog for parameter editing is displayed in a pop-up on the screen as shown in W5. In this dialog, there is a check box for "Dark outside area". When this check box is checked (checked by default), the entire edit window is darkened, and only the selected image is displayed brightly and conspicuously. Conversely, when this check box is turned off, it is possible to set parameters for the selected image while considering the entire image while stereoscopically viewing the entire image. In the layer setting dialog for parameter editing, a change in the parameter is reflected on an image in real time.
[0057]
The layer setting dialog for parameter editing further includes a check box for "edit lock". When this check box is checked, characters, logos, images, and the like pasted in the edit window can be locked (cannot be edited). In particular, a logo image is usually edited in a locked state, so that it is possible to cope with such a situation.
[0058]
FIG. 8 is a flowchart of a program for realizing the function of the layer window processing unit 442.
[0059]
In ST20, a stereoscopic image (3D image) generated based on the LR image is read from a file storage unit or the like and is set as a base layer image. The left and right positions, inclination, deformation, brightness, and the like are adjusted for this image (ST21). For this adjustment, the function of the LR image determination unit 440 described above is used. Subsequently, an edit window W1 and a layer window W2 are set on the screen, and the image is displayed as a base layer. At this time, it is also possible to read a character image or the like with a clear outline as a base layer image.
[0060]
The base layer image is displayed as a thumbnail image in the layer window W2 according to the default layer display order (ST23). Here, the default is the "height" parameter. As described above, instead of this, the display order can be determined using any other parameter such as transparency, size, and update date.
[0061]
When the paste of the new character image is selected in ST24, a stereoscopic image is automatically created for the input character image by the LR image automatic creation unit 43, and the default value of each parameter is added. The added parameters include parameters such as height and transparency, and parameters for performing file storage in the PNG format assuming that the image is an outline holding image.
[0062]
When the attachment of the new logo is selected in ST25, a stereoscopic image is automatically created by the LR image automatic creation unit 43 for the selected logo image, and a default value of each parameter is added. The added parameters include parameters such as height and transparency, and parameters for performing file storage in the PNG format assuming that the image is an outline holding image. Here, it is assumed that the stereoscopic image of the logo is stored in advance and is selected from these.
[0063]
When the pasting of the new image (LR image) is selected in ST26, the stereoscopic image of the input image is pasted, and the default value of each parameter is added.
In ST27, the thumbnail images of all the images including the images added in ST24 to ST26 are displayed in the layer window W2 in the display order set at that time. When the display order is changed to a parameter other than the height, the display order in the layer window W2 is also changed according to the new parameter. When the number of target stereoscopic images increases or decreases, the thumbnail image display order in the layer window W2 is also updated. Note that the display size of the thumbnail image displayed in the layer window W2 can also be changed.
[0064]
In ST29, when any thumbnail image (pasted part) is selected in the layer window W2, the stereoscopic image in the editing window W1 corresponding to the selected image is activated. At the same time, by operating the setting button beside it, the parameter can be edited in the dialog shown in W5. At this time, if “display outside the area is darkened” is set in the dialogue indicated by W5 in FIG. 7, only the activated image is highlighted (other stereoscopic images are darkened). When a parameter is changed in the W5 dialog, the change is reflected on the image in real time.
[0065]
The above processing is repeated, and when the "Save" in the menu is selected after the pasting operation of all the images is completed (ST32, ST33), the outline-preserving image is compressed and stored in the PNG format, and the outline-maintaining image is stored in the PNG format. The other images are compressed and stored in the JPEG format (ST33). At this time, various parameters (height, transparency, pasting position, etc.) are also stored at the same time.
[0066]
With the above functions, when a plurality of stereoscopic images are displayed on the edit screen, these stereoscopic images are displayed as a layer structure, and each stereoscopic image is selectively displayed on the edit screen for each layer, so that each stereoscopic image is displayed. Editing parameters associated with the visual image is facilitated.
