Image processing device and MEMC image block matching method based on image content

Abstract

The invention provides an image processing device and an MEMC image block matching method based on image content. The image processing device comprises an MEMC module, the MEMC module comprises a preprocessing unit, a motion estimation unit and a motion compensation unit, and the preprocessing unit is used for receiving an image frame and judging the scene consistency degree of each image partition in the image frame; the motion estimation unit is used for dynamically controlling the number of candidate vectors of image blocks in each image partition in a search algorithm according to the scene consistency degree of each image partition, and screening out an optimal vector from the plurality of candidate vectors through a matching algorithm to serve as a motion estimation result; and the motion compensation unit is used for generating a motion compensation frame according to the motion estimation result. According to the image processing device and the MEMC image block matching methodbased on the image content, the complexity of a search algorithm can be reduced, the speed and precision of MEMC module estimation are improved, the playing effect of display equipment is smoother, and a better visual effect is brought to a user.

Description

technical field [0001] The present application relates to the field of image processing, in particular to an image processing device and MEMC image block matching method based on image content. Background technique [0002] The current frame rate of mainstream movies is 24fps, the frame rate of TV programs is generally 25fps, and the current refresh rate of mainstream display devices is 60Hz. When we watch TV programs or movies, the screen will increase the refresh rate of the display device by adding repeated frames. This method does not add new screen content to the video, and the quality of the motion picture has not been really changed. When encountering a high-speed motion scene, such as a ball game, there will be "smear" or "blur". [0003] Motion estimation motion compensation (Motion Estimation and Motion Compensation, MEMC) is a technology widely used in frame rate conversion. By estimating the motion trajectory of objects in continuous motion images, and then comb...
