Abstract

The invention discloses an image interpolation processing method, image processing equipment and a storage device. The method comprises the following steps: obtaining an original image, wherein each pixel point in the original image corresponds to a color channel, the color channel corresponding to the most pixel points in the original image is a main color channel, and the other color channels are secondary color channels; dividing pixel points corresponding to the secondary color channels to corresponding interpolation direction areas based on first inter-channel color differences and intra-channel differences of the original image, wherein the first inter-channel color differences represent pixel value differences between the primary color channels and the secondary color channels, and the intra-channel differences represent pixel value differences of the primary color channels; performing main color channel interpolation on the original image based on the divided interpolation direction region to obtain an interpolation image; and performing interpolation of a secondary color channel on the interpolation image to obtain a target color image. According to the scheme, the false color problem can be improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image interpolation processing method, image processing equipment and a storage device. Background technique [0002] When acquiring a color image, a single sensor is usually used to acquire the three primary colors. Before the light enters these sensor arrays, the main color components of green, red, and blue are respectively filtered by a color filter array. The image formed in this case is called a mosaic image. , in a mosaic image, each pixel contains only one color, usually only green, red or blue. The main color components of green, red, and blue can be used to synthesize a full-color image. The process of converting this mosaic image into a full-color image is called "demosaicing". However, in the process of demosaicing, due to the inaccurate judgment of the interpolation direction, the false color problem is caused. Contents of the invention ...
