Embodiment Construction

[0036] Such as figure 1 As shown, the first embodiment of the present invention proposes an image processing method, including:

[0037] Step S101, acquiring an image frame, and dividing the image frame into several sub-regions;

[0038] Step S102, performing image feature analysis and statistics on each sub-region respectively, to obtain image feature information of each sub-region;

[0039] In order to enhance the image processing effect, this embodiment divides the image frame into several sub-regions, so as to analyze and count the image characteristics of each sub-region, and apply an enhancement algorithm to each sub-region to perform image enhancement processing, so as to take into account the local area image. Features, to achieve fine adjustment of the image and improve the effect of image processing.

[0040] Usually, the image enhancement algorithm is to perform statistical analysis on the original image features to obtain image feature information, and then perfo...

Abstract

The invention relates to an image processing method and an apparatus. The method comprises the following steps: capturing frame pictures of an image and dividing them into a plurality of sub-regions; conducting image characteristic analysis and statistics to the sub-regions so as to get characteristic information of images of the sub-regions; applying enhanced algorithms to the sub-regions respectively to have images enhanced according to the characteristic information of images of the sub-regions; mixing the enhanced images to get processed frame pictures of image after treatment. According to the invention, image analysis and enhancing treatment can be done to images of sub-regions with consideration of the image characteristics of a partial region so as to achieve fine adjustment to images and an enhanced image processing effect. In addition, through the equal and enhancing treatment of a sensitive region, the abruptly changing effect caused by blocks generated by the dividing of regions can be avoided and therefore increases the degree of fine adjustment of enhanced algorithms.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] In image processing technology, image enhancement is to purposely emphasize the overall or local characteristics of the image through the analysis of image information. For example, the original unclear image becomes clear or the contrast difference between different object features in the image is enhanced to improve the visual effect of the image. At present, some commonly used algorithms for image enhancement include: contrast change, spatial filtering, image computing, etc. [0003] However, the existing image enhancement methods are often based on taking the entire frame of image content as a statistical area for analysis and statistics, and using an enhancement algorithm to enhance and adjust the entire frame of image content for the same image. In this way, it is difficult to take into ...
