Abstract

The invention discloses a Bayer image processing method and system, electronic equipment and a storage medium. The processing method comprises the following steps: acquiring a plurality of neighborhood pixel points of each target pixel point in a Bayer image; performing interpolation on the channels of the target pixel points corresponding to the other two color parts to obtain a first interpolation result set and a second interpolation result set; obtaining the edge direction of the target pixel point; obtaining a first weight of each first interpolation result in the first interpolation result set and a second weight of each second interpolation result in the second interpolation result set; and filtering the interpolation result according to the first weight and the second weight by adopting a weighted median filtering algorithm to obtain full-color pixel data of the target pixel point, and further generating a full-color image corresponding to the Bayer image. According to the method, different textures of the Bayer image can be effectively recovered, and pseudo-color and zipper effects generated by an existing interpolation technology are effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a Bayer image processing method, system, electronic equipment and storage medium. Background technique [0002] For most digital cameras, CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) sensors are usually used to collect a color component at each pixel point, in order to better recover the other two colors from single pixel point data The acquisition points on the CMOS sensor are usually arranged according to certain rules. Most of the sensors are arranged in the Bayer pattern, and then use the interpolation method to transform the mosaic image in which each pixel in the Bayer image has only one primary color into each The pixels all contain a full-color image of red, green, and blue, that is, interpolation from single-pixel image data to restore full-color image components. This process is usually called demosaicing, also known as ...
