Abstract

The embodiment of the invention provides an image processing method and device. The objective of the invention is to solve the problem of the severe variegation phenomenon. The method comprises: performing global brightness enhancement process of the brightness component of the input image data based on a presetting algorithm, and obtaining the first image data; performing illumination filtering of the brightness component of the first image data by using bilateral filtering, and obtaining the second image data; and determining the feedback coefficient of the saturation component of the first image data, regulating the brightness component of the second image data based on the feedback coefficient, and obtaining and displaying the output image data. The generation of halation is effectively avoided.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an image processing method and an image processing device. Background technique [0002] Some of the original pictures displayed on the TV are not very clear. It is necessary to make the original unclear pictures clear or emphasize some interesting features to enhance the recognition effect of the pictures. [0003] The image processing algorithm used in the current TV system is developed from the grayscale image. The characteristics of the traditional grayscale image processing algorithm are: assuming that the brightness of the image content changes gently, and the filtering method is used when the brightness illuminates the component. The currently used brightness enhancement function is isotropic. When applied to the three primary colors of R, G, and B, the different amplitudes of each component will cause color distortion in which the color is washed out. Because t...
