3D Image Overlap Region Brightness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D image display technologies using glasses type suffer from reduced brightness due to the insertion of black images between left-eye and right-eye images, leading to decreased overall brightness perceived by the user.
Innovation Solution
An apparatus and method that estimate the overlap region between left-eye and right-eye images, generate an overlap image with adjusted pixel values, and control the output to increase brightness, ensuring the left-eye and right-eye images are displayed with enhanced brightness by synchronizing shutters in 3D glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If black images are inserted between left-eye and right-eye images to prevent crosstalk in glasses type 3D display, then crosstalk is prevented, but brightness is reduced
Solution Approach 1:
The patent changes the parameter of the intermediate image from completely black (0 brightness) to having adjusted pixel values that maintain crosstalk prevention while preserving brightness. The image processing unit modifies the brightness parameter of the overlap region to be lower than the left-eye and right-eye images but not completely black, thus resolving the contradiction between preventing crosstalk and maintaining brightness.
2Illumination intensity
If overlap image with adjusted pixel values is generated to maintain brightness, then brightness is improved, but image processing complexity increases
Solution Approach 1:
The patent segments the image processing into distinct regions: non-overlap regions and overlap regions. The image processing unit separately processes these regions with different pixel value adjustment strategies. This segmentation simplifies the overall processing complexity by dividing the task into manageable parts with clear rules for each region.
Solution Approach 2:
The patent applies different processing qualities to different parts of the image. In overlap regions, pixel values are adjusted to prevent crosstalk and maintain brightness, while in non-overlap regions, original pixel values are preserved. This local quality approach optimizes brightness where needed without unnecessarily processing the entire image, thus managing complexity efficiently.

AI summary
A method and apparatus for providing a three-dimensional (3D) image are provided. The method includes receiving a left-eye image and a right-eye image, estimating an overlap region of the left-eye image and right-eye image; generating an overlap image based on the estimated overlap region; and controlling the left-eye image, the right-eye image and the overlap image to be output.
