Video Frame Correction for Retinal Degeneration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for improving binocular vision in individuals with degenerative retinal diseases are limited by the risk of double images, dynamic effects like flicker, and the need for costly hardware, as they rely on the brain's ability to compensate for misalignment and require significant image processing resources, which can lead to loss of fluidity in video streams.
Innovation Solution
A method and system that modify digital video streams by generating distinct streams for each eye, using correction schemes applied to specific portions of video frames based on the eye's reference system, to compensate for visual defects caused by retinal degeneration, thereby improving binocular vision without altering the underlying disease state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing is applied to compensate for retinal defects, then visual perception is improved, but video stream fluidity is degraded due to processing resources consumption
Solution Approach 1:
The patent pre-calculates and stores correction maps for different retinal defect conditions before video playback. During video streaming, these pre-computed correction maps are applied through simple lookup and transformation operations rather than performing complex real-time image processing, thus maintaining video fluidity while achieving defect compensation
Solution Approach 2:
The patent divides the video processing into separate correction stages for left and right eyes, applying specific correction maps to each eye's video stream independently. This segmentation allows parallel processing and optimizes resource utilization, preventing fluidity loss while maintaining perception accuracy
2Reliability
If correction schemes are applied to video frames, then binocular vision is improved, but device complexity increases due to hardware requirements
Solution Approach 1:
The patent replaces complex optical correction hardware with software-based digital correction schemes. Correction maps are generated computationally and applied through image processing algorithms, eliminating the need for specialized optical devices while achieving binocular vision improvement
Solution Approach 2:
The patent creates a universal correction system that can handle multiple types of retinal defects through a single platform. The same hardware infrastructure supports various correction schemes for different defect patterns, reducing overall device complexity while maintaining reliable binocular vision correction
3Measurement precision
If real-time image processing is performed to correct visual defects, then visual perception is improved, but double images and flicker effects occur
Solution Approach 1:
The patent pre-computes correction maps offline and stores them for runtime application. This eliminates real-time processing delays and variations that cause flicker and double images, ensuring stable and consistent visual correction across the video stream
Solution Approach 2:
The patent uses pre-generated correction maps as templates that are applied consistently across video frames. These static correction patterns are copied and applied rather than regenerated for each frame, ensuring image stability while maintaining correction accuracy

AI summary
The present invention relates to a method for modifying at least one video frame of a digital video stream to be displayed on a display area. Each correction scheme has one or more specific digital filters based on visual defects perceived by a person with respect to a video frame portion, is configured when predetermined conditions are met and reconfigured whenever the origin position of an eye reference system associated with a respective eye is different from the position of the same origin in said predetermined conditions and/ or the orientation of said eye reference system is different from the orientation of the same eye reference system in said predetermined conditions. The generation of a multiview digital video stream, subsequent to the application of the first correction scheme and/or the second correction scheme, and the displaying of said digital video stream by a multiview stereoscopic or stereoscopic video system allow to the two eyes of a person to observe a respective succession of video frames, wherein the content of the video frames of each sequence of video frames has been modified on the basis of visual defects of a respective eye of said subject suffering from a degenerative disease of the retina, so that said subject has a visual perception, in binocular vision, improved or corrected.
