Problems solved by technology
However, the current MEMC technology also has defects. The basic algorithm is to insert a motion compensation frame between the traditional two frames of images, which needs to store the original frame data for calculation, which will cause a delay in the output of the picture; in addition, MEMC cannot predict the trajectory of irregular moving objects. , causing ghosting and severe fragmentation of small moving objects in some scenes, so it is difficult to guarantee the picture quality of different TV programs with the same set of MEMC parameters

The invention discloses an image quality improving system and method for a liquid crystal display television having a motion compensation function. The image quality improving system comprises a remote controller, a remote control signal receiving module, a main processor of the liquid crystal display television and a MEMC processing module; the remote control signal receiving module is connected with the remote controller through a wireless network; the remote control signal receiving module and the main processor of the liquid crystal display television are in electric communication connection; the main processor of the liquid crystal display television includes three motion compensation control modes, namely a film and television mode, a sports mode and a game mode; the main processor of the liquid crystal display television and the MEMC processing module are in electric communication connection; and the MEMC processing module includes a MEMC parameter database in the game mode, a MEMC parameter database in the sports mode and a MEMC parameter database in the film and television mode. According to the invention, different contextual modes are set in a television system according to different television programme contents; different MEMC parameters are set according to characteristics of various contextual modes; and thus, the image quality effect in different application scenes is in the optimal state.
Description
technical field [0001] The invention relates to the field of image quality improvement of liquid crystal televisions, in particular to a system and method for improving image quality of liquid crystal televisions with motion compensation functions, which are applied to image processing systems of liquid crystal televisions with motion compensation functions. Background technique [0002] At present, many LCD TVs are equipped with motion image quality compensation (MEMC) function, which can eliminate the jitter and tailing of moving images and enhance the image quality perception of moving images. However, the current MEMC technology is also flawed. The basic algorithm is to insert a motion compensation frame between the traditional two frames of images. It needs to store the original frame data for calculation, which will cause delays in the output of the screen. In addition, MEMC cannot predict the trajectory of irregular moving objects. , causing ghosting and severe fragme...
