Color Correction System for Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Color display variations between actual images taken by a camera and those displayed on a device lead to differences in perceived colors, affecting convenience and accuracy.
Innovation Solution
A user terminal and system that includes a camera, a display device, a color reference data extraction unit, a color comparison unit, and a color correction unit to extract and compare color image data with a color sample, correcting the displayed colors to match the original image.

Engineering Contradiction Analysis
1Measurement precision
If colorimetry is performed at multiple positions within an imaging range, then color measurement coverage is improved, but color display consistency between actual images and displayed images deteriorates due to display device variations
Solution Approach 1:
A color reference sample is introduced as an intermediary standard between the imaging device and display device. The color reference data extracted from the color sample serves as a mediator to bridge the color space differences between capture and display, enabling consistent color representation across different devices.
Solution Approach 2:
The system implements a feedback mechanism where the extracted color reference data is compared against the displayed color data, and correction information is generated based on this comparison. This feedback loop enables continuous color accuracy improvement by adjusting displayed colors to match the reference standard.
2Measurement precision
If color correction is applied to match display colors with actual image colors, then color accuracy is improved, but additional processing steps are required
Solution Approach 1:
Color reference data is extracted and stored in advance before actual image processing. This preliminary action creates a ready-to-use color standard that can be quickly referenced during image display, reducing the complexity of real-time color correction operations.
Solution Approach 2:
The system creates a color copy or representation of the reference standard in the form of color reference data. This copied color information is then used for comparison and correction, simplifying the processing by working with data representations rather than performing complex physical measurements during display.

AI summary
The present invention is to provide a user terminal and a system and a method for correcting a color that improve the convenience by displaying an actual taken image and an image displayed on a display device in same colors. The user terminal includes a camera that takes an image of an object; a display device that displays the object; extracts color image data output when the camera takes an image of a color sample as a color reference provided on the object; compares the extracted color image data with the color of an original color sample; and corrects the color of the object displayed on the display device as a result of a comparison.
