Display Color Correction Using Internal Image Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing color correction methods using external image generators are costly and require special programs for synchronous control, and image output from upper computers is often non-linear due to OS and GPU interference, leading to inaccurate calibration results.
Innovation Solution
A method and apparatus that utilize an internal image generator within the display to process control instructions, allowing direct image generation and output, with optional optical measurement, path switching, and parameter initialization to ensure accurate color correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an external image generator is used to calibrate the display, then color calibration capability is achieved, but device complexity and cost increase
Solution Approach 1:
The image generation function is extracted from the external image generator and integrated into the display device itself. The display controller includes an image generation unit that can generate test images locally, eliminating the need for external hardware while maintaining calibration capability.
Solution Approach 2:
The display controller is designed to perform multiple functions: it controls the display panel, generates test images for calibration, and processes calibration data. This multi-functional design replaces separate external devices, reducing system complexity while preserving calibration accuracy.
2Ease of operation
If image output is controlled through upper computer with OS and GPU, then image generation is achieved, but output linearity deteriorates
Solution Approach 1:
The display controller acts as an intermediary between the upper computer and display panel. It receives control instructions, generates images locally using its own image generation unit, and outputs to the display panel, thereby bypassing the non-linear OS and GPU processing while maintaining operational convenience.
Solution Approach 2:
The display device performs image generation autonomously through its built-in image generation unit in the display controller. This self-service capability eliminates dependence on upper computer processing, ensuring linear and accurate image output while maintaining ease of operation through remote control.

AI summary
Provided are a method, apparatus and system for correcting color, a storage medium and an electronic device. The method for correcting color includes: a first control instruction issued by an upper computer is received and parsed, such that a first parsing result is obtained, where the first control instruction is configured to control a display to output a target image; an internal image generator is enabled, according to the first parsing result, to execute the first control instruction and generate a first image, where the first image corresponds to the target image; and the first image is output to a display panel, and the first image is displayed.
