AI Technical Summary
Technical Problem
During image processing, the downsampling and upsampling of chroma information during the YUV444 to YUV420 conversion can easily cause artifacts at the image edges, affecting image quality.
Method used
By acquiring pixel difference data of the first chromaticity plane, the second chromaticity plane, and the luminance plane of the image to be processed, the filtering weights are determined and the luminance plane is subjected to weighted filtering. The pixel difference features of the chromaticity plane are then fused to match the adjustment of the luminance plane.
Benefits of technology
It effectively reduces distortion phenomena such as false edges and false dots at the boundaries of high-saturation and high-brightness areas in the image, thereby improving image quality.

Abstract
The invention provides an image enhancement method, electronic equipment, a storage medium and a program product. The method comprises the steps of obtaining pixel difference data of a first chrominance plane, a second chrominance plane and a brightness plane of a to-be-processed image, the pixel difference data being used for representing a difference value between a pixel value of each pixel point in a sliding window and a pixel value of a central pixel; the first chromaticity plane and the second chromaticity plane are obtained by respectively performing resolution conversion processing on the first chromaticity initial plane and the second chromaticity initial plane; according to the pixel difference data, a filtering weight is determined, and the filtering weight is used for representing the contribution degree of the pixel value of each pixel point in the current sliding window to the pixel value of the center pixel; performing weighted filtering processing on the brightness plane according to the filtering weight to obtain a target brightness plane; and determining a target image according to the target brightness plane, the first chromaticity initial plane and the second chromaticity initial plane. According to the method, the image quality during image conversion can be improved.
