Abstract

The present invention discloses an image processing device and method, and belongs to the field of image processing technology. The device includes: a sliding module, used to slide in an image in Bayer format to be processed by using an M*N sliding window; a read module, used to read a pixel value of a center pixel point when the center pixel point in the sliding window is a green pixel point; a calculating module, used to calculate a symmetric value of the pixel value of the center pixel point according to the sliding window; a determining module, used to determine an equilibrium output value of the center pixel point according to the pixel value and the symmetric value of the center pixel point; and a generating module, used to generate a processed image according to the equilibrium output value of each green pixel point in the Bayer image to be processed. The problem existing in the background technology, i.e., noise exists in the image due to crosstalk between adjacent pixel points in the image in the Bayer format obtained by Bayer array filtering, is solved; and influences of the crosstalk between the adjacent pixel points in the image are reduced; and the image display effect is improved.

Description

Technical field [0001] The present invention relates to the field of image processing technology, and in particular to an image processing device and method. Background technique [0002] Bayer (Bayer) array is one of the main technologies for realizing color image shooting with photosensitive elements such as CCD (Charge-coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) sensors. [0003] The Bayer array simulates the sensitivity of the human eye to color, using the principle that the human eye’s discrimination sensitivity to G (Green) pixels is greater than R (Red) or B (Blue, blue) pixels, using 1 red 2 The arrangement of green 1 blue converts grayscale information into color information. Such as figure 1 , Which shows a schematic diagram of a 5×5 Bayer array 10, the Bayer array 10 has 5 pixels arranged in both the horizontal and vertical directions. Specifically, the Bayer array 10 includes a Gb channel 11 with interactive green pixels G and blue pixels B, and ...
