Description

  The present invention relates to a display that can be used for a mobile phone, a computer monitor, a game machine, and the like and can be switched between flat display and stereoscopic display.

  Humans perceive views from two different viewpoints, the left eye and the right eye. A human can see the world in a three-dimensional manner by performing processing for obtaining a sense of distance on the images perceived by the left eye and the right eye. Based on this principle, a display for displaying a stereoscopic image can be realized by supplying a pair of left-eye and right-eye stereoscopic images to both eyes of the observer. By controlling the traveling direction of light from the display so that different images can be seen by the left and right eyes, stereoscopic display can be achieved without requiring dedicated glasses.

  As a display technology capable of displaying both a planar image and a stereoscopic image, Japanese Patent Application Laid-Open No. 2003-177357 discloses a technology related to a parallax barrier (parallax barrier). In this technique, a parallax barrier is used to control the direction of light, and the planar image display mode and the stereoscopic image display mode are switched. That is, the parallax barrier functions as a planar image display mode when light is transmitted, and functions as a stereoscopic image display mode when light is not transmitted. Specifically, in the flat image display mode, the parallax barrier is electrically controlled to transmit light, thereby eliminating the light separation by the parallax barrier, and the same image can be seen by the left and right eyes in the flat display content. You can This state is shown in FIG. Since the parallax barrier cannot block, the same image can be seen by the left and right eyes. On the other hand, in the stereoscopic image display mode, as shown in FIG. 3, the parallax barrier is made effective by making light impermeable, and different images are visible to the left and right eyes.

  As described above, the flat image display mode is changed to a state in which the parallax barrier transmits light, and the stereoscopic image display mode is changed to a state in which the parallax barrier does not transmit light, thereby switching between flat display and stereoscopic display on one display. Is possible.

  As described above, the technology for switching between the planar display and the stereoscopic display state using the parallax barrier has been described. Hereinafter, switching between the flat display mode and the stereoscopic display mode will be described as switching between transmission and non-transmission of the parallax barrier.

  By the way, the plane image display and the stereoscopic image display cannot be changed only by switching between transmission and non-transmission of the parallax barrier. It is necessary to arrange the pixel arrangement of the display image memory for a stereoscopic image.

  Next, a pixel arrangement method for stereoscopic image data and planar image data will be described. First, when displaying a planar image, as shown in the schematic diagram of FIG. 4, the image data (a) recorded in the storage image storage unit such as a hard disk or a flash memory is decoded to obtain image data (b ) And the pixel arrangement as it is is written in the display image memory as stereoscopic image data (c). This is the same as the process performed by a normal flat display. In this schematic diagram, an image decomposed into strips in the vertical direction is represented by one line, and in order to simplify the explanation, it is described as having six lines in the horizontal direction.

  On the other hand, a processing example in the case of displaying a stereoscopic image will be described with reference to the schematic diagram of FIG. The image data is stored in the storage image storage unit in a state (a) in which the left-eye image data L and the right-eye image data R are separated. From these data, an image decomposed into strips in the vertical direction is extracted for each line, and image data (b) in which image data for the left eye is arranged on the left side and image data for the right eye is arranged on the right side is generated. In this data, the left half is the left eye image data area, and the right half is the right eye image data area. When displaying, they are rearranged alternately left and right, and written as stereoscopic image data (c) in the display image memory. As shown in FIG. 5 (c), the odd-numbered vertical columns of the display image memory are written with the left-eye image data, and the even-numbered columns are written with the right-eye image data. In this manner, the observer can view a stereoscopic image by making the stereoscopic display mode, that is, the parallax barrier opaque, in the state of writing in the display image memory.

  To summarize the above, to display a stereoscopic image, the parallax barrier is set in a non-transparent state, and the pixel arrangement is alternately left and right, and in order to display a planar image, the parallax barrier is set in a transparent state. What is necessary is just to arrange | position normally.

  So far, the principle of switching between the stereoscopic display mode and the flat display mode has been described. Next, transition processing that gives a visual effect when switching images will be described.

  The transition process is a visual effect that is performed when the screen is changed. When switching between the previous image and the next image, the previous screen disappears while moving either up, down, left, or right, and the next scene appears as “wipe” or the screen gradually disappears. There are “dissolves” that change as the screen melts.

The transition process is widely used when switching images, but is considered to be particularly useful when switching between a stereoscopic image and a planar image. The reason will be explained.
When switching the display of the stereoscopic image to the display of the planar image, the parallax barrier is electrically controlled so as to transmit light. Conversely, when switching the display of a planar image to the display of a stereoscopic image, the light is not transmitted. When these processes are performed, the non-transmission / transmission of light is switched, so that the luminance of the image changes significantly. For this reason, the observer may feel uncomfortable due to a sudden change in luminance.

  As one method to remove this uncomfortable feeling, it is considered effective to perform a transition process that gives a visual effect to the switching image, instead of switching the display mode at once when switching between the display of the planar image and the display of the stereoscopic image. It is done.

  Now, how to implement the transition processing will be described by taking, as an example, the case of a planar image to a planar image and a stereoscopic image to a stereoscopic image.

  FIG. 6 shows a case where the transition processing is performed between the planar image A and the planar image B. In the case of a planar image, display memory data is generated by performing an operation on each of the two pixels. For example, in the case of a dissolve, data in the display memory can be obtained by performing a calculation for allocating a color ratio for each pixel.

  FIG. 7 shows a case where the transition processing is performed between the stereoscopic image A and the stereoscopic image B. Even in the case of a three-dimensional image, the transition process can be executed by performing the same process as that of the planar image.

JP 2003-177357 A

  By the way, the following problems exist when trying to perform a transition process from a planar image to a stereoscopic image or from a stereoscopic image to a planar image.

  In other words, the transition process is a continuous visual effect when the screen is changed, and has the property of gradually changing two images. However, the display has a stereoscopic display mode and a flat display mode, and one of them must be determined. Therefore, in the conventional method, there is a problem that a transition process between a planar image and a stereoscopic image cannot be performed.

  Specifically, for example, in the planar display mode, when switching from a planar image to a stereoscopic image, as illustrated in FIG. 8, the superimposition process is performed in a misplaced state. As a result, in the case of a dissolve, for example, an erroneously superimposed image as shown in FIG. 11 is displayed. This is because the pixel arrangement differs between the stereoscopic image and the planar image as described above.

  In view of the above-described problems of the conventional technology, the present invention enables a switching method between a planar image and a stereoscopic image that reduces a sense of incongruity and abruptness that appears in an observer's eyes, and provides an easy-to-use stereoscopic image display device. For the purpose.

In order to achieve the above object, a stereoscopic image display device having a function of performing transition processing between two consecutive images according to the present invention and capable of switching between a stereoscopic display mode and a planar display mode is provided from a planar image to a stereoscopic display. Means for creating stereoscopic display mode image data that is image data in a data format corresponding to the mode, and when switching from either one of the three-dimensional image display and the two-dimensional image display to the other image display, Transition processing is performed between the stereoscopic display mode image data created from the planar image at the time of switching and the stereoscopic image at the time of switching .

  Here, the transition process is a visual effect performed when the screen is changed. When switching between the previous image and the next image, the previous screen disappears while moving either up, down, left, or right, and the next scene appears as “wipe” or the screen gradually disappears. There are “dissolves” that change as the screen melts.

Then, the three-dimensional image display device according to the present invention, when switching the display to the stereoscopic image from the planar image, to create a three-dimensional display mode image data from the plane image, after switching from the planar display mode to the stereoscopic display mode, the and performing a transition process to the three-dimensional image from the stereoscopic display mode image data.

  Furthermore, the stereoscopic image display device according to the present invention creates stereoscopic display mode image data from a planar image and performs a transition process from the stereoscopic image to the stereoscopic display mode image when switching the display from the stereoscopic image to the planar image. In some cases, the display mode is switched to the flat display mode.

Means for creating flat display mode image data that is image data in a format, and when switching from either one of the three-dimensional image display and the two-dimensional image display to the other image display, the three-dimensional image at the time of the switching The transition processing is performed between the flat display mode image data created from the above and the flat image at the time of switching.

  The stereoscopic image display device according to the present invention creates planar display mode image data from the stereoscopic image and performs a transition process from the planar image to the planar display mode image when switching the display from the planar image to the stereoscopic image. In some cases, the planar display mode is switched to the stereoscopic display mode.

  Furthermore, the stereoscopic image display device according to the present invention creates the planar display mode image data from the stereoscopic image when switching the display from the stereoscopic image to the planar image, and after switching from the stereoscopic display mode to the planar display mode, the stereoscopic image In some cases, a transition process from the image to the flat display mode image is performed.

In addition, a stereoscopic image display method capable of switching between a stereoscopic display mode and a planar display mode while having a function of performing a transition process between two consecutive images according to the present invention includes data corresponding to a stereoscopic display mode from a planar image. A step of creating stereoscopic display mode image data, which is image data of the format, and when switching from one of the three-dimensional image display and the two-dimensional image display to the other image display, from the two-dimensional image at the time of the switching And a step of performing a transition process between the created stereoscopic display mode image data and the stereoscopic image at the time of switching . Then, when switching the display from the planar image to the stereoscopic image, the stereoscopic display mode image data is created from the planar image, and after switching from the planar display mode to the stereoscopic display mode, the transition from the stereoscopic display mode image data to the stereoscopic image is performed. It is characterized by performing processing.

Embodiments of the present invention will be described below with reference to the drawings.
(Embodiment 1)
FIG. 1 is a diagram illustrating a configuration example of a first embodiment of a stereoscopic image display device according to the present invention.
The stereoscopic image display apparatus according to the first embodiment of the present invention includes a storage image storage means 103 for storing a plurality of planar images or stereoscopic images, and a display for storing image data to be displayed when displaying on a display. An image memory 102; display means 101 for displaying the image data of the display image memory 102 as a stereoscopic image or planar image according to the display mode state; a planar / stereoscopic switching means 106 for switching the display mode state; A transition processing unit 104 that performs processing that gives a visual effect when switching the next image, a stereoscopic display mode image generation unit 105 that generates a stereoscopic display mode image for performing the transition processing, and each of the units described above And control means 107 for controlling.

  The display means 101 is a display such as a liquid crystal capable of switching between a plane and a solid. The principle of operation is as described in the description of FIG. 2 and FIG. 3 in the background art section. The display means 101 performs display display based on the information recorded in the display image memory.

  The display image memory 102 is a means for recording information to be displayed on the display means 101, and the arrangement of pixels differs between when displaying a planar image and when displaying a stereoscopic image. The arrangement method is the same as described in the description of FIGS. 4 and 5 in the background art section.

  The storage image storage unit 103 is a storage unit for holding data for a long time. Generally, a hard disk, flash memory, or the like is used. In the present invention, a plurality of planar image files and stereoscopic image files are stored here.

  The transition processing unit 104 generates a visual effect that is performed when the screen is changed. Examples of transitions include “dissolve”, “wipe”, “cross stretch”, “zoom”, and the like.

  “Dissolve” is a visual effect in which when the previous image and the next image are switched, the next screen gradually melts as the screen gradually disappears. FIG. 10A shows how the dissolve changes. “Wipe” is a visual effect in which when the previous image and the next image are switched, the previous screen disappears from the screen while moving either up, down, left, or right, and the next scene appears. FIG. 10B shows how the wipe changes. “Cross stretch” is a visual effect in which, when switching the previous image and the next image, the width of one image is expanded and the width of the other image is reduced. FIG. 10C shows how the cross stretch changes. “Zoom” is a visual effect in which an image appearing in the center is gradually enlarged and replaced when switching between a previous image and a next image. FIG. 10D shows how the zoom changes. Various other transitions exist, and the present invention is not limited to the transition processing described above.

  The stereoscopic display mode image generation unit 105 plays a role of generating a stereoscopic display mode image from the planar image stored in the storage image storage unit 103 and passing it to the transition processing unit 104. A method for generating a stereoscopic display mode image will be described later.

  The plane / stereoscopic switching unit 106 is a unit that switches the display mode of the display unit 101 to the planar image display mode or the stereoscopic image display mode based on an instruction from the control unit 107. As described above, in the planar image display mode, the parallax barrier of the display unit 101 is made transparent, and in the stereoscopic image display mode, the parallax barrier is made opaque.

  The control means 107 controls the storage image storage means 103, the display image memory 102, the display means 101, the transition processing means 104, the stereoscopic display mode image generation means 105, and the plane / stereoscopic switching means 106 so as to control two images. And a transition process between them. The control method will be described with reference to the flowchart of FIG.

  The processing flow of the present invention will be described with reference to FIG. Of the two images, the currently displayed image is image C, and the next displayed image is image D. In the initial state, the image C is displayed (S11). If the current plane display mode is selected (S12), if the next image D is a plane image (S13), the conventional transition processing is performed on the images C and D (S14). If the next image D is a stereoscopic image (S13), a stereoscopic display mode image C 'is generated by the stereoscopic display mode image generating means (S15).

Here, a method for generating a stereoscopic display mode image will be described.
In general, several methods are known to convert a planar image into a stereoscopic image, as will be described later, but here, a method of simply creating an image in a stereoscopic display mode rather than actually generating a stereoscopic image. Will be described.

FIG. 9 shows a transition process between the stereoscopic image A (data of the stereoscopic image A is shown in FIG. 9 (a)) and the planar image B (data of the planar image B is shown in FIG. 9 (b)). It is the figure which showed the mechanism which produces | generates a stereoscopic display mode image when doing. In the following description, for convenience of description, each image having the data of FIGS. 9 (a), (b), (c), (d), (e) is represented as images (a), (b), Sometimes referred to as (c), (d), (e).
As described with reference to FIG. 7, regarding the arrangement of the stereoscopic image data when performing the transition processing or the like, the left half is the left-eye image and the right half is the right-eye image. Accordingly, in the stereoscopic display mode image generation means 105, for example, if the odd-numbered columns of the original image are allocated to the left half and the even-numbered columns are allocated to the right half (see FIG. 9C), the image in the stereoscopic display mode is obtained. Can be generated. However, an image created by this method does not look three-dimensional. However, it is considered that there is no significant effect on the part used in the process of performing the transition process even if it does not look three-dimensional.

  On the other hand, there is a method of using an algorithm for converting a planar image into a stereoscopic image in order to create an image that can be viewed stereoscopically in the stereoscopic display mode. Various methods have been proposed. For example, as disclosed in Japanese Patent Application Laid-Open No. 2000-228778, there is a method of generating a stereoscopic image by performing a special calculation on a planar image.

  FIG. 9D shows image data generated by performing a transition process on the image (c) and the image (a) generated by the above method. (e) is data in the display image memory that has undergone the transition process, and is displayed in the stereoscopic display mode state on the display means.

  By the method described above, a stereoscopic display mode image C ′ (meaning a stereoscopic display mode image of the planar image C. Hereinafter, the same notation is performed) is generated by S15 in the flowchart of FIG. Switch to the mode (S16). Then, a transition process is performed on the image C ′ and the image D (S17), and finally the image D is displayed (S18), and the process ends.

  FIG. 13 illustrates the above-described transition process from a planar image to a stereoscopic image. Starting from the state in which the planar image A is displayed in the planar display mode (FIG. 13A), the stereoscopic display mode image generating means 105 generates a stereoscopic display mode image A ′ based on the planar image A (FIG. 13). 13 (b)). Next, after switching to the stereoscopic display mode and displaying the image A ′ (FIG. 13C), the transition process from the image A ′ to the image B is performed (FIG. 13D), and finally the stereoscopic image B is displayed. Is displayed (FIG. 13 (e)).

Next, the flow in the case of the current stereoscopic display mode (S12) will be described. If the next image D is a stereoscopic image, a transition process is performed on the stereoscopic image C and the stereoscopic image D (S14).
If the next image D is a flat image, the stereoscopic display mode image D ′ is generated by the stereoscopic display mode image generating means (S20). Then, transition processing is performed on the images C and D ′ (S21), and after switching to the flat display mode (S22), the image D is displayed (S18).

  FIG. 14 illustrates the transition processing from the stereoscopic image to the planar image described above. Starting from a state in which the stereoscopic image B is displayed in the stereoscopic display mode (FIG. 14A), the stereoscopic display mode image generating means 105 generates a stereoscopic display mode image A ′ based on the planar image A (FIG. 14). 14 (b)). Then, a transition process from the image B to the image A ′ is performed (FIG. 14 (c)), and after the stereoscopic image A ′ is displayed (FIG. 14 (d)), the mode is switched to the plane display mode, and finally the image A Is displayed (FIG. 14 (e)).

  With the above flow, the transition from the planar image to the planar image, the stereoscopic image to the stereoscopic image, the planar image to the stereoscopic image, and the stereoscopic image to the planar image can all be performed. The feature of the present invention is that a transition process from a planar image to a stereoscopic image and from a stereoscopic image to a planar image is enabled.

(Embodiment 2)
Next, a second embodiment of the present invention will be described.
The method described above with reference to the flow chart performs transition processing in the stereoscopic display mode. Here, the transition process is performed in the flat display mode.

FIG. 15 is a block diagram of the present invention. Except for the flat display mode image generation means 208, it is the same as the configuration diagram of FIG. The flat display mode image generation unit 208 is a unit that generates a flat display mode image from a stereoscopic image. The generation method will be described later.
A flowchart is shown in FIG. Since the outline of the processing flow is almost the same as the flowchart of FIG. 12, only the transition processing of the planar image C and the stereoscopic image D will be described here.
When the image C is displayed (S101), in the current plane mode (S102), and the next image D is a solid (S103), a plane display mode image D ′ is first generated.

Here, a method for generating a flat display mode image will be described.
FIG. 17 shows a transition process between a planar image A (data of the planar image A is shown in FIG. 17A) and a stereoscopic image B (data of the stereoscopic image B is shown in FIG. 17B). It is the figure which showed the mechanism which produces | generates a flat display mode image when doing. As described with reference to FIG. 7, the arrangement of the stereoscopic image data when performing the transition processing or the like is such that the left half is the left eye image and the right half is the right eye image.

  Therefore, in the flat display mode image generation unit, for example, only the left eye image of the original stereoscopic image is taken out and arranged in the odd and even columns (FIG. 17 (c)), the flat display A mode image can be generated.

  However, the planar image created by this method is half the resolution in the horizontal direction, so it does not become a high quality image. However, even if the quality is not good, it is considered that there is no significant effect on the amount used in the part of the transition process.

  FIG. 17D shows image data generated by performing a transition process on the image (c) and the image (a) generated by the above method. (e) is data in the display image memory that has undergone the transition process, and is displayed in the flat display mode state on the display means. After the transition process is completed, the stereoscopic image is displayed by switching to the stereoscopic display mode.

  By the method described above, when switching from a stereoscopic image to a planar image, or from a planar image to a stereoscopic image, it is possible to reduce a sense of incongruity or suddenness that appears in the eyes of the observer.

(Other matters)
Both the stereoscopic display mode image generation unit 105 and the flat display mode image generation unit 208 may be provided, and either one of the image generation units may be appropriately selected and used.

  The present invention can be suitably implemented in a display that can be used for a mobile phone, a computer monitor, a game machine, or the like and can be switched between a flat display and a stereoscopic display.
