Title: IMAGE PROCESSING METHOD AND APPARATUS
Abstract:
An image processing method and apparatus. The method comprises: acquiring an image frame picture, and dividing the image frame picture into several sub-partitions; respectively analysing and counting image features of the various sub-partitions, so as to obtain image feature information about the various sub-partitions; and according to the image feature information about the various sub-partitions, using an enhancement algorithm to perform image enhancement processing on the various sub-partitions respectively, and merging the various enhanced images to obtain a processed image frame picture. By means of image analysis and enhancement processing of sub-partitions, the characteristic of a local region image can be considered, thereby finely adjusting the image and improving an image processing effect; in addition, by means of equilibrium enhancement processing of a sensitive region, a mutation effect between blocks generated due to partition processing under some situations can be avoided, thereby improving the fine adjustment degree of an image enhancement algorithm.
