Stereoscopic Image Color Conversion for Binocular Rivalry Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to adequately address the difference in color appearance between the right and left eyes when viewing stereoscopic images with head-mounted displays due to variations in color matching functions among individuals, leading to binocular rivalry and flickering.
Innovation Solution
An image processing apparatus that acquires user-specific color vision characteristics to perform color conversion on input images, adjusting the color appearance of right and left eye images to match the user's individual color perception differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If color conversion is performed using standard color matching functions, then color consistency across displays is improved, but individual differences in color perception between right and left eyes cause binocular rivalry and flickering
Solution Approach 1:
The patent applies different color conversion characteristics specifically to the right eye image and left eye image based on individual color vision characteristics. Instead of uniform color conversion, the system adjusts color coordinates separately for each eye using measured individual differences in color matching functions, thereby eliminating binocular color discrepancies while maintaining overall color consistency
Solution Approach 2:
The patent measures and utilizes individual color vision characteristics by obtaining color matching functions for each eye and calculating color vision characteristics representing individual differences. These measured parameters are then applied to convert color coordinates of right and left eye images differently, transforming the standard color conversion parameters into personalized parameters that match the user's actual color perception
2Reliability
If individual color vision characteristics are measured and applied, then color appearance matching between right and left eyes is improved, but processing complexity and measurement requirements increase
Solution Approach 1:
The patent performs color vision characteristic measurement in advance before actual stereoscopic image viewing. The color matching functions for each eye are obtained beforehand, and color vision characteristics are calculated and stored. This preliminary measurement eliminates the need for real-time complex calculations during image display, reducing processing complexity while maintaining accurate color matching
Solution Approach 2:
The patent creates a digital model of individual color vision characteristics by measuring and storing color matching functions and calculated color vision characteristics. This digital copy of the user's color perception profile is then used to apply appropriate color conversion to right and left eye images without requiring physical measurement devices during actual viewing, simplifying the system complexity

AI summary
An image processing apparatus for generating a right eye image and a left eye image, includes one or more memories storing a program, and one or more processors that, upon execution of the stored program; are configured to operate as an acquisition unit configured to acquire a color vision characteristic representing a color appearance difference between right and left eyes of a user; and a conversion unit configured to perform color conversion on at least any one of the right eye image and the left eye image based on the color vision characteristic.
