Abstract

The invention discloses a color gamut amending IP core of an LED display screen video signal and a method thereof. The IP core comprises a sink module, a three-order RGB2XYZ parallel processing module, an XYZ2xyz normalized module, a three-order color gamut amending parallel processing module, an xyz2XYZ de-normalized module, a three-order XYZ2RGB parallel processing module and a source module which are connected in sequence; and the other input end of the three-order parallel processing module is connected with a three-order matrix operation module. The IP core can be used for expanding the color gamut of a video source signal by using fewer hardware resources, has reusable codes and configurable parameters, and can be applied to various wide color gamut display equipment and can be compatible with a video processing circuit and the traditional video processing IP core.

Description

technical field [0001] The invention relates to a video processing technology of an LED display screen, in particular to an IP core and a method thereof for correcting the color gamut of a video signal in the video signal processing of an LED display screen. Background technique [0002] The color gamut correction circuit in the video processing system of the LED display screen completes the color gamut matching between the existing video signal source standard and the LED display screen, and improves the display distortion of the LED display screen caused by the different color gamuts of the two. Correcting the color gamut of the video source signal is one of the most important links in the video processing system of the LED display. The method and efficiency of the color gamut correction directly affect the display quality of the LED display. There are two existing color gamut correction methods. The first method is based on the conversion relationship between the three pr...
