Anaglyph Image Color Adjustment for Eye Strain Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Regular color anaglyph images suffer from saturated colors not being portrayed well, causing eye strain and retinal rivalry due to brightness and contrast differences, and ghosting issues.
Innovation Solution
A method that adjusts color temperature, shifts hues, and adjusts tone and saturation in a stereo RGB image pair to reduce red rivalry, convert images between RGB and YCbCr domains, and combine them to generate an anaglyph image, optimizing color balance and reducing eye strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If regular color anaglyph images are generated using the typical method of combining red channel from left image and green/blue channels from right image, then color information is preserved, but saturated colors are not portrayed well and cause eye strain and retinal rivalry
Solution Approach 1:
The patent applies parameter changes by adjusting color temperature, shifting hues, and modifying saturation levels of the red channel. Specifically, it reduces the vibrancy of red colors and adjusts blue colors to be less intense, transforming the color parameters to eliminate retinal rivalry while preserving essential color information in the anaglyph image.
Solution Approach 2:
The patent directly addresses color issues by changing the color characteristics of the image channels. It shifts the hue of red towards magenta to reduce vibrancy, adjusts blue colors to reduce intensity, and modifies color saturation to achieve better color balance. These color changes eliminate the harmful saturated colors that cause eye strain while maintaining color representation.
2Measurement precision
If brightness and contrast are increased to improve image quality, then color representation improves, but eye strain and retinal rivalry increase
Solution Approach 1:
The patent optimizes brightness and contrast parameters within safe ranges that do not trigger retinal rivalry. It adjusts these parameters selectively across different color channels, increasing visibility where needed while maintaining color balance, thereby improving color representation without causing eye strain.
3Loss of information
If color saturation is increased to enhance vividness, then color portrayal improves, but ghosting and color leaks between eyes increase
Solution Approach 1:
The patent carefully controls color saturation parameters to achieve optimal color portrayal without excessive saturation. It adjusts saturation selectively, reducing it in color ranges that cause ghosting while maintaining or enhancing saturation in ranges that improve color representation, thereby eliminating color leaks between eyes.

AI summary
A method includes reducing a red rivalry through adjusting a color temperature on a first image, converting the first image from the RGB domain to a YCbCr domain, shifting a hue of a red color in the first image towards a magenta color to reduce a red color vibrancy, and adjusting a blue color in the first image such that a dark blue visible through a second lens corresponding to a second image is at least partially visible through a first lens corresponding to the first image. The method also includes reducing the red rivalry through adjusting a tone of the red color in the first image towards a brown color, converting the first image from the YCbCr domain back to the RGB domain, adjusting a color saturation in the first image, and combining the first image with the second image in a processor to generate an anaglyph image.
