Abstract

The invention discloses an image false color processing method. The image pseudo color processing method comprises the steps of obtaining a real-time image in a YCrCb format; Calculating a pseudo color processing factor of each pixel of the real-time image according to the spatial correlation characteristic and the spectral correlation characteristic of the real-time image; Obtaining a distribution map of the pseudo color information on the real-time image according to the pseudo color processing factor of each pixel; And adjusting the chromaticity of the pixel according to the pseudo color processing factor of each pixel to obtain a pseudo color removed image. In addition, the invention also discloses an image false color processing device. According to the image pseudo-color processing method and the image pseudo-color processing device, pseudo-color removal processing is directly carried out on the real-time image with the color space being YCrCb, the pseudo-color detection and pseudo-color processing method is simple, and the calculated amount is small.

Description

technical field

[0001] The invention relates to the technical field of image processing, in particular to an image false color processing method and an image false color processing device. Background technique

[0002] Color images typically consist of three channels (red, green, blue) per pixel. Acquiring such color images would require a camera with three spatially correct sensors, each passing through a color filter placed in front of it to capture the corresponding visible spectrum information. However, considering the size, cost, imaging effect, etc., most color cameras only have a single sensor with a color filter array (CFA) placed in front of the camera. To restore full-color images from CFA samples, color interpolation or demosaicing is required. One of the undesired effects of the demosaicing process is false coloring. False colors appear as noticeable color errors near the edges of objects. Demosaicing using spatial correlation and spectral correlation propert...
