Parallax Image Generation Device Depth Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for depicting three-dimensional images using parallax images often result in unnatural appearances at the image edges, leading to a decreased display size when attempting to address this issue.
Innovation Solution
A parallax image generation device that performs depth value correction to shift pixels closer to the display screen as they approach the image edges, generating corrected parallax images to maintain the stereoscopic effect without reducing the image size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a stereoscopic frame is disposed to cover an end portion of a three-dimensional image, then unnatural depiction at the end portion is reduced, but the display size of the three-dimensional image is decreased
Solution Approach 1:
The patent applies parameter changes by modifying depth values in the depth image for pixels located at end portions of the image. Specifically, depth values are corrected to shift corresponding object positions closer to the display screen, which eliminates the unnatural appearance without requiring border frames that would reduce display area. This transforms the depth parameter selectively for end portion pixels to achieve natural depiction while maintaining full display size.
2Manufacturing precision
If depth values are corrected to shift positions closer to the display screen at image ends, then unnatural depiction is reduced, but the complexity of image processing increases
Solution Approach 1:
The patent applies local quality by implementing depth value correction only for pixels located at end portions of the image, while leaving the depth values of pixels in the central region unchanged. This localized approach corrects unnatural depiction at boundaries without unnecessarily complicating the processing of the entire image, thereby reducing overall processing complexity while maintaining naturalness where it is most needed.

AI summary
A parallax image generation device includes: a depth value correction unit which performs correction processing on a depth value, from among a plurality of depth values which define a depth image, to shift a position corresponding to the depth value to be closer to a display screen as the depth value is located closer to an end of the depth image, the display screen being for displaying a parallax image; and a parallax image generation unit which generates a first parallax image and a second parallax image having mutual parallax, using a two-dimensional image and the depth image corrected through the correction processing.
