Display Compensation for Image Distortion Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image distortion occurs when users view displays due to varying distances from different points on the display to the user, affecting the display experience.
Innovation Solution
A display compensation method and module that receive an image signal, determine the user's position relative to the display, and compensate the image signal by converting it into sub-image blocks, calculating their distances to the user, and applying a preset formula to adjust their sizes based on these distances, thereby outputting a compensated image signal to correct for distortion.

Engineering Contradiction Analysis
1Area of stationary object
If the display size is very large or the distance from the user to the display is very close, then the display coverage is improved, but the image distortion increases
Solution Approach 1:
The patent applies local quality by dividing the display into multiple sub-image blocks and applying different compensation factors to each block based on its distance from the user. Closer blocks are enlarged while farther blocks maintain their original size, ensuring uniform visual appearance across the entire display surface.
Solution Approach 2:
The patent segments the display into multiple sub-image blocks and processes each block independently with different compensation factors. This segmentation allows the system to address the varying distances to different points on the display by applying localized size adjustments to each segment.
2Measurement precision
If the image size is enlarged for close viewing, then the viewing clarity is improved, but the image distortion increases
Solution Approach 1:
The patent applies local quality by adjusting the size of different regions of the image based on their distance from the user. Regions closer to the user are enlarged to maintain clarity, while regions farther away are kept at their original size, preventing distortion.
Solution Approach 2:
The patent dynamically adjusts the size of image blocks based on the user's position and the distance from each block to the user. The compensation factor is calculated in real-time based on geometric relationships, allowing the display to adapt to different viewing conditions and maintain optimal clarity without distortion.

AI summary
There are provided a display compensation method, a display compensation module and a display apparatus. The method comprises following steps: receiving an image signal to be displayed (S1); obtaining a user position (S2) which is a relative position of a user relative to a the display apparatus; compensating for the image signal to be displayed according to the user position to obtain a compensated image signal (S3); and outputting the compensated image signal (S4). The display compensation method, the display compensation module and the display apparatus can be used for manufacturing the display, and can avoid the image distortion occurred to the image viewed by the user due to the different distances from the user to respective points on the display such that the user's experience in the display effect of the display can be raised.
