Display Image Processing for Low-Vision Outline Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with poor vision or impaired vision face difficulties in accurately perceiving images displayed on devices due to vision problems, necessitating improved accessibility solutions.
Innovation Solution
A display device that processes input images to generate both a first image for general users and a second image for low-vision users, enhancing outlines and adjusting resolutions based on user input or distance, and optionally includes features like a camera for positional tracking and a speaker for audio commentary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image quality processing is performed to enhance visibility for low-vision users, then image visibility is improved, but processing complexity increases
Solution Approach 1:
The patent divides the image processing into two separate processing paths: a first image quality processing path for standard images and a second image quality processing path for low-vision users. This segmentation allows each path to be optimized independently, with the second path applying specific enhancements (outline emphasis, flattening, resolution adjustment) only when needed, thereby improving visibility without unnecessarily complicating the overall system.
Solution Approach 2:
The patent applies different processing qualities to different parts of the image based on user needs. For low-vision users, the system applies enhanced processing including outline emphasis and flattening to specific regions of the image, while maintaining standard processing for other areas. This local quality approach improves visibility for the target users without uniformly increasing processing complexity across all image data.
2Adaptability or versatility
If multiple processed images are generated and displayed simultaneously, then accessibility for low-vision users is improved, but device complexity increases
Solution Approach 1:
The patent implements a dynamic image display system that can switch between displaying a single standard image and displaying multiple processed images simultaneously. The system dynamically determines which display mode to use based on user needs and can transition between modes. This dynamic approach enhances accessibility for low-vision users when needed while avoiding unnecessary complexity during standard operation.
Solution Approach 2:
The patent introduces an image processing unit as an intermediary component that generates processed images from the original input image. This intermediary processing layer allows the system to maintain the original image while creating enhanced versions for low-vision users, enabling simultaneous display of multiple images without fundamentally altering the core display system architecture.
3Measurement precision
If resolution is increased for enhanced outline visibility, then outline emphasis is improved, but processing time increases
Solution Approach 1:
The patent applies outline emphasis processing as a preliminary step before final image rendering. By pre-processing the image to enhance outlines and then maintaining this enhanced version for display, the system avoids the need for real-time high-resolution processing during normal operation. This preliminary action approach improves outline visibility while reducing processing time during playback and interaction.

AI summary
A display device comprises: a display, and at least one processor, comprising processing circuitry, connected to the display and individually and/or collectively, configured to control the display device to: acquire a first image by performing first image quality processing to an input image, based on the input image being received, and acquire a second image by performing second image quality processing to the input image, and display the first image and the second image, and the second image quality processing comprises at least one of planarization processing for the input image, and outline line processing for emphasizing the outline line of an object included in the input image.
