Problems solved by technology

The introduction of the AM driving method will inevitably lead to more obvious non-linearity of LED display, and more diverse forms of Mura (that is, uneven display) of LEDs. Therefore, an image correction and display method that can be applied to various driving methods is required. In order to achieve better calibration and display effect

Abstract

The embodiment of the invention relates to an image correction and correction data generation method, a device, a system and an image display method. The image correction method comprises the following steps: acquiring data of a plurality of pixel points of a to-be-corrected image; and performing correction processing on each piece of pixel point data to obtain a corrected image, and specificallycomprises the steps of obtaining a maximum color component value in a plurality of color component values of the pixel point data, and obtaining saturations corresponding to the plurality of color component values, and searching correction data from a correction data set according to the maximum color component value and the saturation degree to obtain target correction data, and correcting the plurality of color component values by using the target correction data to obtain corrected pixel point data corresponding to the pixel point data. According to the embodiment of the invention, different correction data can be selected according to the color component values of the pixel point data, and proper correction data can be selected for correction, so as to achieve a better correction effect.

Description

technical field [0001] The present invention relates to the technical field of image display and correction, in particular to an image correction method, an image correction device, an image correction system, a correction data generation method, a correction data generation device and an image display method. Background technique [0002] With the development of LED display technology, LED display screens have been applied to various fields due to their advantages of low cost, low power consumption, high visibility, and freedom of assembly. At the same time, with the popularization of LED display applications, people have higher and higher requirements for its display quality. Therefore, how to improve the display quality of LED display screens has become a research hotspot in this field. [0003] One of the more difficult problems at present is that the brightness and chromaticity uniformity of the image displayed on the LED display screen is relatively poor (that is, ther...
