Daltonized Image Decoder for Color Vision Deficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems for color vision deficiency (CVD) often disrupt the viewing experience for non-CVD individuals, as they modify digital media in ways that may not be suitable for all viewers, leading to inconsistent color adjustments that can affect the enjoyment of visual digital media.
Innovation Solution
An image decoder system that receives metadata to determine appropriate color mappings for images, allowing for real-time adjustment of colors to create a 'daltonized' version that is easier for CVD individuals to distinguish, while maintaining the original image for others, and can store user preferences for future use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing systems modify digital media to help CVD individuals distinguish colors, then color differentiation for CVD individuals is improved, but the viewing experience for non-CVD individuals deteriorates
Solution Approach 1:
The system segments the viewer audience into CVD and non-CVD individuals, providing different color mapping versions of the same digital media to each segment. This allows color differentiation assistance for CVD viewers without degrading the experience for non-CVD viewers, as each group receives the appropriate version.
Solution Approach 2:
The system applies different color mapping qualities to different viewers based on their visual needs. CVD individuals receive images with color adjustments optimized for their condition, while non-CVD individuals receive the original or differently adjusted versions, ensuring each viewer experiences the media with the appropriate local quality for their needs.
2Adaptability or versatility
If a single color mapping is applied to all images, then processing simplicity is maintained, but adaptability to different viewing conditions and user preferences deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-processing digital media into multiple color mapping versions before distribution. Different color mappings are prepared in advance for different CVD types and preferences, allowing the system to adapt to various viewing conditions without complex real-time processing when the actual viewing occurs.
Solution Approach 2:
The system changes parameters by applying different color mapping transformations to the same source image. By varying the color mapping parameters according to the viewer's CVD type and preferences, the system achieves high adaptability while the underlying processing mechanism remains consistent, managing complexity through parameter variation rather than structural complexity.

AI summary
Systems and methods are related to daltonizing images. An image decoder can receive a first image and a second image. The images can be associated with a first metadata and second metadata, respectively. The image decoder and determine a color mapping for the first image and the second image based on the first metadata and the second metadata. The image decoder can process the images in a color vision deficiency (CVD) processor and based on the images and their associated metadata generate daltonized images which are sent to a display.
