Problems solved by technology
[0005] In addition, the more important point is that when the red, green, and blue monochromatic colors of LED displays in multiple batches have been adjusted to be consistent, it is found that the white is not completely consistent, and the difference between batches is even greater. It is difficult to keep the same color, how to quickly find the balance point between monochrome and white has always been the difficulty of the whole adjustment process

Embodiment Construction
[0022] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] see figure 1 , which is a schematic flowchart of steps of a method for correcting brightness and chromaticity of an LED display device based on human vision according to an embodiment of the present invention. Aiming at the problem that it is difficult to adjust / correct the difference in brightness and chromaticity of LED display devices that use different batches of LED lamp points by human visual judgment, this embodiment can intelligently predict the adjustment effect of the difference based on computer programs, and combined with the human visual judgment, the selection method can be greatly improved. To reduce the difficulty of adjustment and realize fast adjustment / correction of differences in brightness and chromaticity b...

The invention relates to a method and system for correcting bright the color degree of an LED display device based on human vision, and a method for correcting the regional bright color degree. The method comprises the steps of acquiring a monochrome adjustment matrix for correcting monochrome images corresponding to different colors in a region, obtaining a mixed color adjustment matrix by using the monochrome adjustment matrix, obtaining another mixed color adjustment matrix based on human vision, obtaining correction coefficient errors of a plurality of color components between the two mixed color adjustment matrixes, comparing the correction coefficient errors of the plurality of color components with preset error thresholds of the correction coefficients corresponding to the color components respectively, determining distribution of the correction coefficient errors of the plurality of color components to the correction coefficients corresponding to the color components in the monochrome adjustment matrix, and obtaining a corrected monochrome adjustment matrix. The corrected monochrome adjustment matrix can be further applied to update and correction of bright color degree correction coefficients of the region. The invention can be used for quickly finding out the balance point between the monochrome and the mixed bright color degree and improving the correction efficiency.
Description
technical field [0001] The invention relates to the technical field of LED display correction, in particular to a method and system for correcting brightness and chromaticity of an LED display device based on human vision and a method for correcting regionalized brightness and chromaticity. Background technique [0002] Since the 21st century, the color display industry has developed unprecedentedly, and LED display screens have spread all over the central squares and commercial buildings of various cities. LED display is highly praised by people for its unique advantages of bright colors, high visibility, and low power consumption. However, due to the relatively low level of domestic LED display manufacturing technology, the produced LED lights themselves have relatively large brightness and chromaticity. For example, the same production batch of LED lamps may have a brightness difference of nearly 50%, and a chromaticity difference of 15-20nm; and a display screen spliced ...
