Abstract

The embodiment of the invention discloses a method and device for storing a proofreading matrix based on an LED screen, which is used to effectively reduce the storage space to store the proofreading matrix, and further solve the technical problem of high economic cost. The method in the embodiment of the present invention includes: obtaining the first matrix data value corresponding to the compression element, the compression element being at least one element on the diagonal line between the first element and the last element of the proofreading matrix; The value is subtracted from the preset average value to obtain the difference; according to the difference, the compressed elements are compressed and stored according to the number of bits corresponding to the difference; other unselected elements are stored according to the number of bits corresponding to the matrix data value of other elements Compressed storage.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a method and device for storing a proofreading matrix based on an LED screen. Background technique [0002] In computer graphics, a color gamut is some complete subset of colors. The most common application of color subsets is to accurately represent a given situation. Examples include a given color space or the color range of an output device. Generally, the color gamut of the LED display is 1.4 times that of the general display. Therefore, in order to display the correct color and brightness, it is necessary to correct the color signal of the color gamut. [0003] The existing technology of correcting the color signal of the color gamut usually needs to convert the video input signal into the signal to be input into the LED after the matrix correction process through the correction matrix, so that the LED display screen can display the correct color and brightness, ...
