Embodiment approach

[0073] The implementation of adjusting the brightness of each normalized component image according to the interpolation curve corresponding to the original RGB image includes the following two:

[0074] 1) Mode 1. After obtaining the normalized component images, linearly interpolate the normalized component images according to the interpolation curve corresponding to the original RGB image to obtain corresponding interpolated images, such as normalized The normalized component images are L_I_Y, L_I_Cb and L_I_Cr, then the corresponding interpolation images are represented by Linear_img(Y), Linear_img(Cb) and Linear_img(Cr), and then each pixel in each normalized component image The pixel value of each point is multiplied by the pixel value of each pixel point in each corresponding interpolation image to adjust the brightness of each component image. If the adjusted Y component image is represented by the symbol L_H_Y, then the adjusted Y component image The calculation formula...

Abstract

The invention discloses an RGB image processing method. The method includes converting initial RGB images into YCbCr images; performing normalization processing on components in the YCbCr images and obtaining component images subjected to normalization; performing luminance adjustment on the component images subjected to normalization according to an interpolation curve corresponding to the initial RGB image so as to obtain the adjusted component images; obtaining a YCbCr image subjected to processing through overlapping the component images subjected to adjustment and converting the processed YCbCr image into an RGB image for outputting. The invention also discloses an RGB image processing system. According to the invention, RGB image processing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an RGB image processing method and system. Background technique [0002] The traditional high dynamic display image is to process the brightness of the image, first convert the original image into a color chromaticity space image containing the brightness Y component, and then process the image in this color chromaticity space, and in the process of image processing , when an image contains different brightness regions, if the same image processing algorithm is used, the brightness of the image processing will be unbalanced, which will affect the display of the texture or color features of the image. In order to balance the brightness of the final processed image, so that For the clear display of texture or color features, it is necessary to use Canny edge detection, image grayscale processing, image expansion and corrosion processing, image local transformation,...
