The invention discloses a color correction method and device, a color correction device and a storage medium. The method includes: inputting and storing 3D-LUT correction reference color data; inputting original color RGB data for 3D-LUT mapping, and obtaining The color data after the LUT mapping; the color data after the 3D-LUT mapping is corrected by using the tetrahedral interpolation algorithm and the 3D-LUT correction reference color data to obtain the corrected color data. Through the embodiment of the present invention, by adopting the 3D-LUT color correction method based on tetrahedral interpolation, the calculation of tetrahedral interpolation coefficients can be effectively simplified, and in specific circuit applications, only four multipliers are needed to optimize tetrahedral interpolation The algorithm simplifies the implementation of the hardware circuit, greatly reduces the difficulty of hardware circuit implementation, and improves the real-time performance of circuit data processing, thereby solving the problem of complex interpolation coefficients in the tetrahedral interpolation calculation and complicated hardware circuit implementation in the prior art.
Description
technical field [0001] The present invention relates to the field of color correction, in particular to a color correction method and device, a color correction device and a storage medium. Background technique [0002] As a new type of display technology, LED display (Light Emitting Diode) is more and more favored by users due to its advantages of energy saving, environmental protection and high efficiency. However, due to the influence of LED display production process, different LED display cannot achieve The range of displayed colors (that is, color gamut) is the same, which leads to differences when different LED displays display the same color. Large-sized LED displays are often spliced by multiple small LED displays due to technology and other reasons. The effect of a small LED display on the same color display is inconsistent, so the display effect of the entire LED display is very poor. [0003] The current solution is to find out the common color gamut (referenc...
