Problems solved by technology

However, if two images are adjusted with the same gamma curve, the brightness and chromaticity of the two images after adjustment will be quite different from the luminance and chromaticity to be reflected by the data source itself, especially the brightness or color of the two images. When the difference is large
However, if two sets of independent gamma curves are used to adjust the two images, a large number of parameters need to be collected, taking too much resources and time, and there will be a large difference in brightness or chromaticity between the two images after adjustment. , allowing users to have a visual gap when viewing two images

Abstract

The invention provides a picture adjusting method and a display system. The method comprises the following steps of displaying two pictures, displaying color patterns in the two pictures respectively,measuring a first original parameter and a second original parameter of each color pattern on the corresponding picture, and obtaining adjusting parameters of the two pictures obtained on the basis of the first original parameters and the second original parameters. According to the picture adjusting method and the display system, the brightness and chromaticity differences of the two pictures can be reduced.

Description

technical field [0001] The invention relates to a picture adjustment method and a display system, in particular to a picture adjustment method and a display system capable of reducing the brightness difference between two pictures. Background technique [0002] Currently, some display devices can simultaneously display multiple pictures, such as Picture by Picture (PBP), Picture in Picture (PIP), etc., for users to watch. When displaying a picture, the display device usually performs gamma correction on the picture to adjust the brightness and color performance of the picture. However, if two images are adjusted with the same gamma curve, the brightness and chromaticity of the two images after adjustment will be quite different from the luminance and chromaticity to be reflected by the data source itself, especially the brightness or color of the two images. When the difference is large. However, if two sets of independent gamma curves are used to adjust the two images, a ...
