DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to two kinds of different images for the left and right eyes, such as a stereoscopic television and an experimental binocular stereoscopic apparatus.
The present invention relates to a binocular stereoscopic device that provides a stereoscopic effect by presenting .

[0002]

2. Description of the Related Art Conventionally, as a binocular stereoscopic apparatus, a method of presenting a left-eye image 101 to a left eye and a right-eye image 102 to a right eye as shown in FIG.

[0003]

In the conventional binocular stereoscopic apparatus, as shown in FIG. 3, images 101 and 102 are displayed while including the non-corresponding area 103 at the left and right ends of the screen. For this reason, an area (non-corresponding area 103) which exists only in the image of one eye is generated at the left and right ends of the screen, and a visual field conflict occurs to reduce the stereoscopic effect.

[0004] It is an object of the present invention to improve the three-dimensional effect without causing visual field conflict.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a method for distinguishing right and left eyes.
Binocular stereoscopic device that presents two types of images:
Between the presented right eye input image and the presented left eye input image
Therefore, the correlation between the pixels of both input images is less than a predetermined threshold.
Examine pixels that are below and within the parallax range
To find the corresponding pixel area,
Other regions from the right eye input image and the left eye input image
It is configured to be removed and presented on the output side .

[0006]

The present invention has an effect of suppressing or eliminating visual field conflict because an area that exists only in one eye image is not displayed at the left and right edges of the screen.

[0007]

Embodiments of the present invention will be described below with reference to screens. FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, reference numeral 1 denotes an image storage unit, 2 denotes a corresponding point detecting unit, 3 denotes a left and right end non-corresponding region removing unit, and 4 denotes a display unit.

[0008] The left eye input image and the right eye input image read from the image storage unit 1 are output to the corresponding point detection unit 2 and the left and right end non-corresponding region removal unit 3. In the corresponding point detection unit 2,
The left-eye image 101 and the right-eye image 102 based on the correlation between the left-eye input image and the right-eye input image input from the image storage unit 1
Is obtained, and information on the non-corresponding region 103 in the left-eye image 101 and the non-corresponding region 103 in the right-eye image 102 is output to the left and right non-corresponding region removing unit 3 as a region other than the correlated region. .

[0009] The left and right end non-corresponding region removing unit 3 is configured to input a left-eye image non-corresponding region information and a right-eye image non-corresponding region information input from the corresponding point detecting unit 2 to a left and right image. The non-corresponding regions located at the left and right ends of the eye input image and the right eye input image are removed, and the resulting left eye output image and right eye output image are output to the display unit 4. Display unit 4
Is displayed such that the left-eye output image input from the left and right end non-corresponding region removing unit 3 is input to the left eye of the observer, and the right-eye output image is input to the right eye of the observer.

FIG. 4 shows left and right eye output images according to the present invention. In the figure, reference numeral 104 denotes a left-eye output image, and 105 denotes a right-eye output image. FIGS. 5 and 6 together constitute one flowchart showing the processing of the corresponding point detection unit shown in FIG. 1, and A in FIG. 5 is connected to A in FIG.

The pixel value of the left eye image at the pixel position (x, y) is L (x, y), and the pixel value of the right eye image is R (x, y).
And Also, the value of the parallax at the pixel position (x, y) is d
(X, y), and the range of possible parallax values is −D ≦ d ≦ + D. Further, the magnitude of the correlation between the left and right pixels with respect to the parallax d at the pixel position (x, y) is expressed as C (x, y, d) = 1 / {L (x, y) -R (x + d, y)}. The threshold for the presence / absence determination is C _th .

Then _, the following processing is performed for all pixel positions (x, y). Processing: First, the value of the parallax d is preset to -D. Processing: It is checked whether or not the value of the parallax d at a certain pixel position (x, y) is equal to or less than + D. If NO, the process proceeds.

Processing: If YES, the magnitude C of the correlation between the left and right pixels is calculated. Processing: Next, add 1 to the parallax d and return to the processing.
The process proceeds after several times.

Processing: When the result is NO in the processing, the value of the parallax d is set to -D, the value of CMAX is set to zero, and the value of DMAX is set to zero. Processing: It is checked whether or not the value of the parallax d is equal to or less than + D.
If NO, proceed to processing (10).

Processing: If YES, the value of CMAX is determined by the correlation magnitude C (x, y,
Check if it is smaller than d). If NO, the process proceeds.

Processing: If YES, set the magnitude of the correlation C (x, y, d) to the value of CMAX, and
The value of the parallax d is set to X. Processing: Increase the parallax d by 1, and return to the processing. After several times, the process proceeds to processing (10). Process (10): It is checked whether or not the value of CMAX at that time is larger than a threshold value C _th of the correlation magnitude. If NO, proceed to processing (12). Process (11): If YES in process (10), it means that there are corresponding pixels on the left and right, and the value of the parallax d where the value of DMAX is taken is determined. Process (12): If NO in process (10), it means that there is no corresponding pixel on the left and right, and the pixel is regarded as a non-corresponding point.

[0017]

According to the present invention, since there is no region at the left and right ends of the screen which is present only in the image of one eye, visual field competition is suppressed or eliminated, and an improvement in three-dimensional effect can be realized.
