Image color adjustment method, device and storage medium based on wide color gamut

Abstract

The present invention discloses an image color adjustment method, device and storage medium based on wide color gamut, the method specifically includes: inputting an original image and converting it into a wide color gamut color space, separating a color channel and a brightness channel, converting the data into RGB data of a wide color gamut, and outputting a result graph; since the image is transferred to a wide color gamut for processing, the color adjustment algorithm has a larger color adjustment space than a narrow color gamut space, and the color adjustment result is more delicate and not prone to faults; since the color adjustment operation is converted into an operation in a wide color gamut space where color and brightness can be separated, no matter how many times the color adjustment is performed, it can be mapped into an operation in a wide color gamut space, and the execution efficiency of the algorithm is better; the present invention is friendly to Raw image data, and can well support the color adjustment of Raw data without modifying the algorithm, and can support non-Raw data by forcibly changing the color space. The algorithm has good compatibility.
