Abstract

PURPOSE:To improve the stereoscopic sense while suppressing visual field competition by detecting the correspondence between left and right pictures and devising the device such that an area only in existence in a picture of one eye at left and right ends of a pattern is not displayed. CONSTITUTION:A left right end non-correspondence area elimination section 3 eliminates a non-correspondence area placed at left and right ends of a left eye input picture and a right eye input picture inputted from a picture storage section 1 based on left eye picture non-correspondence area information and right eye picture non-correspondence area information inputted from a corresponding point detection section 2. As a result, obtained left eye output picture and right eye output picture are outputted on a display section 4. The display section 4 displays the picture such that the left eye output picture inputted from the elimination section 3 is inputted to the left eye of an observer and the right eye output picture inputted from the elimination section 3 is inputted to the right eye of the observer respectively. Since an area which is in existence in a picture of one eye only is avoided at left and right ends of the pattern, visual field competition is suppressed or eliminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binocular stereoscopic device, such as a stereoscopic television or an experimental binocular stereoscopic device, which gives a stereoscopic effect by presenting two different images to the left and right eyes. is there.

[0002]

2. Description of the Related Art Conventionally, as a binocular stereoscopic device, as shown in FIG. 2, a method of presenting the left eye image 101 to the left eye and the right eye image 102 to the right eye as they are is used.

[0003]

In the conventional binocular stereoscopic device, as shown in FIG. 3, images 101 and 102 are displayed with the non-corresponding regions 103 included at the left and right ends of the screen. For this reason, a region (non-corresponding region 103) that exists only in the image of one eye is generated at the left and right ends of the screen, and binocular rivalry occurs to reduce the stereoscopic effect.

It is an object of the present invention to improve the stereoscopic effect by preventing binocular rivalry.

[0005]

According to the present invention, the correspondence between left and right images is detected, and an area which exists only in the image of one eye is not displayed at the left and right edges of the screen.

[0006]

The present invention has the effect of suppressing or eliminating binocular rivalry because the areas that are present only in the image of one eye are 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 is an image storage unit, 2 is a corresponding point detection unit, 3 is a left and right non-corresponding region removal unit, and 4 is a display unit.

The left-eye input image and the right-eye input image read from the image storage unit 1 are output to the corresponding point detecting unit 2 and the left and right non-corresponding region removing 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.
Areas corresponding to and are obtained, and the information of the non-corresponding area 103 in the left-eye image 101 and the non-corresponding area 103 in the right-eye image 102 is output to the left and right non-corresponding areas as the areas other than the corresponding areas. ..

The left and right non-corresponding area removing section 3 receives the left image input section 1 from the corresponding point detecting section 2 based on the left eye image non-corresponding area information and the right eye image non-corresponding area information. 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 4
Displays such that the left eye output image input from the left and right non-corresponding region removal unit 3 is input to the observer's left eye, and the right eye output image is input to the observer's right eye.

FIG. 4 shows left and right eye output images according to the present invention. Reference numeral 104 in the drawing denotes a left eye output image, and 105 denotes a right eye output image. 5 and 6 together form one flowchart showing the processing of the corresponding point detecting unit shown in FIG. 1, and A in FIG. 5 is connected to A in FIG.

At the pixel position (x, y), the pixel value of the left-eye image is L (x, y) and the pixel value of the right-eye image is R (x, y).
And In addition, the value of the parallax at the pixel position (x, y) is d
Let (x, y) be, and the range of possible values of parallax be −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 set to C (x, y, d) = 1 / {L (x, y) -R (x + d, y)}, and the correlation Let C _th be the threshold value for the presence / absence determination.

Then _, the following processing is performed for all pixel positions (x, y). Processing: Initially, the value of parallax d is preset to -D. Processing: Check whether the value of the parallax d at a certain pixel position (x, y) is + D or less. 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 processing,
Go to the process after several times.

Process: When the result of the process is NO, 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: Check whether the value of the parallax d is + D or less.
If NO, go to process (10).

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

Processing: If YES, the above CMA
The value of X is set to the correlation magnitude C (x, y, d), and the value of parallax d is set to DMAX. Process: Add 1 to the parallax d and return to the process. After several times, proceed to processing (10). Process (10): It is checked whether or not the MAX value at that time is larger than the threshold value C _th of the correlation magnitude. If NO, process
Proceed to (12). Process (11): If YES in process (10), it means that there is a corresponding pixel on the left and right, and the value of the parallax d where the value of the 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]

As described above, 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, the binocular rivalry is suppressed or eliminated, and the stereoscopic effect can be improved.
