Problems solved by technology

[0004] Since the inserted intermediate frame is the same as the adjacent film signal frame, when the moving image is played on the TV, the phenomenon of image jitter and pause often occurs, which greatly affects the viewing effect

Embodiment Construction

[0037] In order to make the advantages of the technical solution of the present invention more clear, preferred embodiments of the image processing method and device of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Inter-frame predictive coding is realized through the correlation (temporal correlation) between adjacent frames of video images. In image transmission technology, moving images, especially TV images, are the main objects of concern. A moving image is a temporal image sequence composed of consecutive image frames at intervals of a frame period, and it has greater correlation in time than in space. Most of the detail changes between adjacent frames of TV images are very small, that is to say, there is a strong correlation between video image frames. When there are moving objects in the image, simple prediction cannot receive good results. If the background of the current frame is exactly the same as th...

Abstract

The invention discloses an image processing method and an image processing device and relates to the image processing field, solving the problems of jitter and pause when a television presents a moving picture. The method comprises: an inbetween is generated by adopting an inbetween prediction coding method with motion compensation; and the inbetween is inserted in a current frame image. The device comprises an inbetween generation module and an insertion module. The use of the image processing method and the device can eliminate the phenomena of jitter and pause when the television and other display devices present the moving picture, thereby leading the presenting of the image to be smoother.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image processing method and device used for playing motion pictures on a television. Background technique [0002] Movies are generally produced by collecting images at 24 frames per second, and the playback frequency of movies produced by this production method is also 24 frames per second. However, since the broadcasting frequency of the TV set is 50Hz (PAL system) or 60Hz (NTSC system), that is, 50 frames or 60 frames of images are played per second, so the TV set cannot normally play the images produced by collecting 24 frames per second. movie of. [0003] In order to solve the above problems, the prior art provides a method for interpolating frames, which can make the TV set normally play the movie produced in the acquisition mode of 24 frames per second. The method specifically includes: regularly inserting an intermediate frame into a movie image (referred to as a mov...
