[Prior art]
In recent years, development of display devices capable of viewing an image as a three-dimensional stereoscopic image has been actively performed. This display device displays an image for the right eye and an image for the left eye on one screen. For example, using a three-dimensional filter, the image for the right eye is displayed on the right eye, and the image for the left eye is displayed on the left. By projecting on the eye, the image is recognized as a solid. In addition, recently, there has been developed a device in which a monitor surface has a three-dimensional filter function so that an image can be viewed stereoscopically without a three-dimensional filter.
[0003]
By the way, when displaying an image, a so-called fade-in / fade-out function of gradually raising or erasing the image is often employed. This function is used at the break of images and programs, and a display effect such as driving the viewer's interest is given by this function.
[0004]
Various methods have already been studied and developed for the fade-in / fade-out function in the field of two-dimensional image display. For example, in Patent Document 1 below, when an image is faded in using a circular wipe that gradually expands, the enlargement of the circular wipe is temporarily stopped in the middle, thereby further improving the display effect at the time of fade-in. Is described.

The features of the present invention will become more apparent from the following description of embodiments.
However, the following embodiment is merely one embodiment of the present invention, and the meaning of the term of the present invention or each constituent element is not limited to that described in the following embodiment. .
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
First, FIG. 1 shows a configuration of a three-dimensional stereoscopic image display apparatus according to the embodiment. In the present embodiment, the raw image data is two-dimensional image data, and three-dimensional image data is generated from the two-dimensional image data.
[0022]
As illustrated, the three-dimensional stereoscopic image display apparatus includes an input device 101, a command input unit 102, a control unit 103, a transition effect control unit 104, an image plane generation unit 105, a parallax image generation unit 106, a display control unit 107, and a display device. 108, a storage unit 109, a development memory 110, and a graphic memory 111.
[0023]
The input device 101 includes input means such as a mouse and a keyboard, and is used for command input such as configuration / editing of playback images, playback commands, image feed commands, fade-in / fade-out commands, and the like. The command input unit 102 sends various commands input from the input device 101 to the control unit 103. The control unit 103 controls each unit according to the input command transferred from the command input unit 102.
[0024]
The transition effect control unit 104 executes and controls display screen rotation processing in response to a fade-in / fade-out command input from the input device 101. The processing in the image plane creation unit 105 will be described in detail later.
[0025]
The image plane creation unit 105 obtains a geometric figure of the display image when viewed from the left eye viewpoint and the right eye viewpoint according to the rotation angle input from the transition effect control unit 104. The processing in the image plane creation unit 105 will be described in detail later.
[0026]
The parallax image generation unit 106 generates left-eye image data and right-eye image data from the two-dimensional image data expanded in the expansion memory 110 and maps them to the graphic memory 111. When a transition effect command is input from the transition effect control unit 104, the left-eye image and the right-eye image are accommodated in the left-eye geometry and the right-eye geometry input from the image plane creation unit 105. As described above, the image data for the left eye and the image data for the left eye are nonlinearly compressed, and both the compressed image data are mapped to the graphic memory 111. The processing at the time of the transition effect will be described in detail later.
[0027]
The display control unit 107 sends the image data stored in the graphic memory 111 to the display device 108 in response to a command from the control unit 103. The display device 108 reproduces the image data received from the display control unit 107 on the display screen.
[0028]
The storage unit 109 is a database that stores a plurality of image files, and each image file stores a predetermined number of still image data. Here, each still image data is data for displaying a two-dimensional image in the present embodiment.
[0029]
The expansion memory 110 is configured by a RAM (Random Access Memory), and is used when temporarily storing still image data read from the storage unit 109. The graphic memory 111 includes a RAM, and sequentially stores the image data for 3D stereoscopic display generated by the parallax image generation unit 106.
[0030]
Next, the operation of the 3D stereoscopic image display apparatus will be described. First, a normal reproduction operation will be described.
[0031]
When an image reproduction command for a predetermined file is input to the three-dimensional stereoscopic image display device, the first still image data among the still image data constituting the file is read and expanded on the expansion memory 110. . Thereafter, the parallax image generation unit 106 generates right-eye image data and left-eye image data from the read image data, and right-eye image (R image) and left-eye image (L image) are obtained. For example, the right-eye image data and the left-eye image data are mapped onto the graphic memory 111 so as to be arranged on the screen as shown in FIG.
[0032]
In the figure, “R” indicates the display area (pixel) of the image for the right eye on the screen, and “L” indicates the display area (pixel) of the image for the left eye on the screen. Such display area allocation is determined according to the configuration of the three-dimensional filter. That is, when the display image is viewed through the three-dimensional filter, the display area of the R image and the L image is projected so that the R image is projected on the viewer's right eye and the L image is projected on the viewer's left eye. (Pixel) is assigned.
[0033]
Thus, the image data mapped on the graphic memory 111 is sent to the display device 108 by the display control unit 107 and reproduced on the display screen.
[0034]
Thereafter, when a still image image sending command is input from the input device 101, the still image data of the next still image constituting the file is expanded on the expansion memory 110, and the same processing as described above is executed. . Similarly, every time a feed command is input, the next still image data is developed on the development memory 110, and the above processing is executed. As a result, the still image images constituting the file are sequentially displayed on the display device 108.
[0035]
Next, the operation during the fade-in / fade-out process will be described.
First, the geometric figure generation process executed by the image plane creation unit 105 during the fade-in / fade-out process will be described with reference to FIG.
[0036]
As shown in FIG. 3A, the geometric figure generation process assumes a left-eye viewpoint L and a right-eye viewpoint R in front of the display screen and at a predetermined distance from the display screen. From this state, as shown in FIGS. 5B and 5C, the display screen is sequentially rotated by an angle α, and the display screen is viewed from the left eye viewpoint L and the right eye viewpoint R in each rotation state. The geometric figure is obtained by calculation.
[0037]
The L image plane and the R image plane shown in the figure schematically show the shapes of geometric figures when the display screen is viewed from the left eye viewpoint L and the right eye viewpoint R, respectively. As shown in the drawing, the L image plane and the R image plane have different shapes corresponding to the parallax between the left eye viewpoint L and the right eye viewpoint R. Therefore, by applying the L image and the R image to the L image plane and the R image plane, respectively, parallax occurs between the image projected to the left eye and the image projected to the left eye, and the image in the rotation state is It becomes visible as a stereoscopic view.
[0038]
Next, the parallax image synthesis process executed by the parallax image creation unit 106 during the fade-in / fade-out process will be described with reference to FIG.
[0039]
In such parallax image synthesis processing, first, the original image data (two-dimensional image data) is compressed in half in the horizontal direction to generate L image data and R image data, which are expanded on the expansion memory 110. . Next, the L image data and the R image data are arranged so that the images of the generated L image data and the R image data fall within the L image plane and the R image plane generated by the image plane creating unit 105, respectively. The image data is nonlinearly compressed (or expanded) in the vertical and horizontal directions, respectively. The compressed L image data and R image data are mapped to corresponding positions of the L image data area and the R image data area on the graphic memory 111.
[0040]
The middle part of FIG. 4 schematically shows a state in which the original image data (upper part of the figure) is compressed in half in the horizontal direction, and the lower part of the figure shows the L image data and R generated in this way. FIG. 6 schematically shows a state in which the image data is mapped on the graphic memory 111 so that the image data fits in the L image plane and the R image plane, respectively.
[0041]
As shown in the lower part of the figure, the L image plane and the R image plane are set to be maximum on the display screen. However, the magnification of the L image plane and the R image plane with respect to the prime size (the size of the L image plane and the R image plane calculated according to FIG. 3) is the same. Also, the L image plane and the R image plane are set so that the centers in the vertical and horizontal directions coincide with each other.
[0042]
It should be noted that background image data (for example, single color data) is mapped to an empty area generated on the graphic memory 111 when the compressed L image data and R image data are mapped on the graphic memory 111.
[0043]
FIG. 5 shows a processing flow when such a fade-in / fade-out command is input.
When a fade-in / fade-out command is input, first, the image data for L and the image data for R are generated by compressing the two-dimensional image data of the still image currently being reproduced by 1/2 in the horizontal direction, The data is expanded on the expansion memory 110 (S101). Further, the two-dimensional image data of the still image to be reproduced next is read from the storage unit 109, and is compressed in half in the horizontal direction to generate L image data and R image data. Expanded upward (S102).
[0044]
Thereafter, the rotation angle of the image plane is input from the transition effect control unit 104 to the image plane generation unit 105 (S103), and the L image plane and the R image plane (geometrical pattern information) corresponding thereto are converted into the image plane generation unit. 105 is calculated (S104). Note that the rotation angle of the image plane is set to a unit rotation angle α in the first processing cycle, and then increased by the rotation angle α as the processing cycle proceeds. At this time, the unit rotation angle α corresponds to this speed when the speed of fade-in / fade-out can be set appropriately. Further, the rotation angle may be changed for each processing cycle. Thereby, the display effect at the time of fade-in / fade-out can be further improved.
[0045]
Accordingly, when the L image plane and the R image plane are set, it is next determined whether or not the rotation angle exceeds 90 ° (S105). Here, if the rotation angle is less than 90 °, the rotation of the display screen has not shifted from the front surface to the back surface, so the L image currently being reproduced as an image to be displayed on the L image plane and the R image plane. Image data and R image data are set (S106). On the other hand, if the angle exceeds 90 °, the rotation of the display screen has shifted from the front surface to the back surface, so that the L image data to be reproduced next as an image to be displayed on the L image plane and the R image plane. And R image data are set (S107). Note that no image is set when the rotation angle is 90 °. At this time, neither the L image plane nor the R image plane exists.
[0046]
When the image data to be displayed is selected in this way, the selected L image data and R image data are then non-linearly compressed so as to fit in the L image plane and the R image plane, respectively. (S108). The compressed L image data is mapped to the L image data area on the graphic memory 111 (S109), and background image data (for example, a single color) is mapped to the L image data area remaining after the mapping. (S110). Similarly, the compressed R image data is mapped to the R image data area on the graphic memory 111 (S111), and the background image data is mapped to the R image data area remaining after the mapping (S112).
[0047]
Thus, when the mapping process on the graphic memory 111 is completed, the image data on the graphic memory 111 is transferred to the display device 108. As a result, the image for the right eye and the image for the left eye are embedded on the display screen that has been artificially rotated by a predetermined amount, and an image in which a background image is embedded in another empty area is displayed on the display device 108. (S113).
[0048]
The processes of S103 to S113 are executed until the pseudo rotation of the display screen reaches 180 °, that is, until the display screen is turned over from the front surface to the back surface (S107). As a result, the previous still image is replaced with the next still image, and the fade-in / fade-out operation is completed.
[0049]
As described above, according to the present embodiment, it is possible to stereoscopically view the image on the display screen in the rotated state while artificially rotating the display screen, so that it is possible to realize a fade-in / fade-out operation full of realism.
[0050]
In the above-described embodiment, the display screen is pseudo-rotated in the horizontal direction. However, in addition to this, the display screen can be rotated in various directions such as the vertical direction, the left-right direction, or a combination thereof. In this case, the image plane creation unit 105 performs calculation processing on the display screen in each rotation state according to the calculation processing principle of FIG. 3, and calculates the L image plane and the R image plane in each rotation state. .
[0051]
Further, in the above embodiment, the image plane creation unit 105 calculates the L image plane and the R image plane. However, when the rotation direction and the rotation angle are fixed, each rotation angle is set to each rotation angle. The corresponding L image plane and R image plane are calculated and stored in advance, and during the fade-in / fade-out process, the L image plane and the R image plane corresponding to the rotation angle of the processing cycle are read out, You may make it utilize this.
[0052]
The structural example of the three-dimensional stereoscopic image display apparatus in the case of FIG. 6 is shown. In this configuration example, a geometric plane information storage unit 105a that stores an L image plane and an R image plane according to the rotation angle is arranged. Further, the image plane creation unit 105 reads the L image plane and the R image plane according to the rotation angle input from the transition effect control unit 104 from the geometric plane information storage unit 105 a, and sends them to the parallax image generation unit 106. send.
[0053]
FIG. 7 shows a fade-in / fade-out process flow in such a case. In this processing flow, S104 is changed to S120 in the processing flow of FIG. Other processing is the same as the processing flow of FIG.
[0054]
In the above embodiment, the still image data stored in the storage unit 109 is two-dimensional data. Instead, three-dimensional still image data (left-eye image data and right-eye image data) is used. Can be stored in the storage unit 109. In this case, in the configuration of FIG. 1, L image data and R image data corresponding to a still image to be reproduced are read from the storage unit 109 and expanded in the expansion memory 110.
[0055]
In this embodiment, the function of the parallax image generation unit 110 during normal playback is different from that in the above embodiment. That is, in this embodiment, during normal playback, the L image data and R image data expanded in the expansion memory 110 are mapped as they are to the corresponding areas on the graphic memory 111, so that the parallax image generation unit in the above embodiment In this embodiment, the process of generating L image data and R image data from two-dimensional image data, which is performed during normal reproduction by the image processing unit 106, is omitted.
[0056]
In this configuration example, when the fade-in / fade-out operation is performed, the L image data and the R image data expanded in the expansion memory 110 are subjected to nonlinear compression processing so as to fit in the L image plane and the R image plane as they are, It can also be configured to map this on the graphic memory 111. However, since these L image data and R image data originally have parallax corresponding to the display of a stereoscopic image, if this is applied as it is to the plane for L image and the plane for R image, the influence of the original parallax will be exerted. Appears in the reproduced image, and distortion occurs in the stereoscopic view.
[0057]
This distortion can be suppressed by providing the parallax image generation unit 106 with a function of eliminating the parallax. Specifically, two-dimensional image data is once generated from the L image data and the R image data developed in the development memory 110, and the two-dimensional image data is processed in the same manner as in the above-described embodiment to obtain an L image. Data and R image data are reconstructed.
[0058]
FIG. 8 shows a fade-in / fade-out processing flow in such a case. In this processing flow, S101 and S102 in the processing flow of FIG. 5 are changed to S130 and S131.
[0059]
That is, in the processing flow of FIG. 5 described above, the image data for L and the image data for R are generated from the two-dimensional image data in S101 and S102 and expanded on the expansion memory 110, but in the processing flow of this configuration example, First, in S130, the L image data and R image data of the next three-dimensional still image are expanded on the expansion memory 110 (the L image data and R image data currently being reproduced are already stored on the expansion memory 110 during normal reproduction). Then, in S131, from the L image data and R image data currently being reproduced and the L image data and R image data to be reproduced next, the image data for L for the still image currently being reproduced and R image data, L image data to be reproduced next, and R image data are reconstructed. Other processing is the same as the processing flow of FIG.
[0060]
In the reconstruction process in S131, as described above, two-dimensional image data is once generated from the L image data and the R image data, and this two-dimensional image data is processed in the same manner as in the above-described embodiment to perform the L image. A method of reconstructing data and R image data may be employed. However, when this method is executed by a series of arithmetic processing, the generation process of two-dimensional image data is omitted, and the L image data and R image data are directly used. It is also possible to reconstruct the L image data and the R image data.
[0061]
According to this processing flow, since the stereoscopic parallax originally included in the L image data and the R image data can be eliminated, a realistic fade-in / fade-out operation can be realized as in the above embodiment.
[0062]
In the above embodiment, the present invention is applied to a so-called two-lens three-dimensional stereoscopic image display device. However, the present invention is applicable to a three-dimensional stereoscopic image display device having a larger number of photographing viewpoints. It can also be applied to.
[0063]
That is, in the above embodiment, as shown in FIG. 3, two geometric figures viewed from the L viewpoint and the R viewpoint are generated. However, when the number of viewpoints exceeds two viewpoints, Assuming that the viewpoint is the front of the display screen, the graphic figure viewed from each viewpoint is calculated in the same manner as in FIG. 3, and the graphic memory is nonlinearly compressed so that the image data of each viewpoint fits in the corresponding geometric figure. Just map it up. FIG. 9 shows an example of generating a geometric figure when the present invention is applied to a three-dimensional stereoscopic image display device for four eyes. The figure (a) shows the geometric figure when the display screen is viewed from each viewpoint when the display screen is not rotated, and the figure (b) is when the display screen is rotated by a predetermined amount. Fig. 6 schematically shows a geometric figure when the display screen is viewed from each viewpoint.
[0064]
As mentioned above, although embodiment which concerns on this invention was described, it cannot be overemphasized that this invention is not limited to the said embodiment, A various change is possible for others.
[0065]
For example, in the above embodiment, the background image is a single color, but it is of course possible to use other background images.
[0066]
In the above embodiment, the L image data area and the R image data area on the graphic memory 111 are allocated so that the L image plane and the R image plane are maximized on the display screen. The method for assigning the L image data area and the R image data area on 111 is not limited to this. For example, until the rotation angle reaches 90 ° (until switching from the front surface to the back surface), the L image plane The graphic memory 111 is configured such that the R image plane gradually decreases on the display screen and the L image plane and the R image plane gradually increase on the display screen until the rotation angle reaches 90 ° to 180 °. The upper L image data area and R image data area may be assigned.
[0067]
Moreover, although the said embodiment applied this invention to the display technique at the time of fade-in / fade-out, this invention can also be applied to display techniques other than fade-in / fade-out. For example, the present invention can be applied to a case where the display screen is pseudo-rotated in the three-dimensional space or the display screen is pseudo-fixed obliquely in the three-dimensional space to give a special effect to the image display. is there.
[0068]
In addition, the embodiments of the present invention can be variously modified as appropriate within the scope of the technical idea of the present invention.
[0069]
Note that the three-dimensional stereoscopic image display apparatus according to the present embodiment can also be realized by adding the functions of the configuration examples in the respective embodiments to a personal computer or the like. In such a case, a program for executing the function of each configuration example is downloaded to a personal computer by loading a disk or via the Internet. The present invention can also be abstracted as a program for providing such a function.
[0070]
【The invention's effect】
As described above, according to the present invention, it is possible to provide a new fade-in / fade-out function using the special characteristics of 3D image display.
