Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Please refer to figure 1 , this embodiment provides an implementation method for intelligently adjusting image quality based on dynamic and static images, the method comprising the following steps:

[0020] (1) The CPU detects the brightness distribution 201, obtains the brightness information of the screen, and compares the current screen brightness with the brightness information of the previous screen in DDR, and judges the screen brightness change 202. If there is a change in the screen brightness, it is directly judged as Dynamic picture 208, exit the judgment process;

[0021] (2) If the picture brightness does not change, then detect the chromaticity distribution 203, obtain the chromaticity information of the picture, and compare the chromaticity of the current picture with the previous picture chromaticity information in DDR, and judge ...

Abstract

The invention relates to an intelligent picture quality adjusting method based on dynamic and static pictures. The method is characterized by comprising the steps of obtaining brightness and chromatic information of the pictures through a central processing unit (CPU) of a television, comparing the brightness and chromatic information with previous brightness and chromatic information in a DDR, dividing the current pictures into windows, obtaining brightness and chromatic information of each window, comparing the brightness and chromatic information with brightness and chromatic information of windows of previous pictures at the same positions to distinguish whether the pictures are static or dynamic, and setting picture parameters according to distinguishing results. According to the method, picture qualities can be adjusted by distinguishing whether displayed pictures are dynamic or static, manual adjustment of picture quality parameters is not needed, and users are enabled to obtain visual enjoyment and pleasure.

Description

technical field [0001] The invention relates to the technical field of television picture quality adjustment, in particular to a method for realizing intelligent picture quality adjustment based on dynamic and static pictures. Background technique [0002] Traditional TV sets do not distinguish dynamic images from static images, and mostly obtain brightness or chrominance information of images based on input signals. According to the obtained information, then simply set the image quality parameters. Or the user manually adjusts the image quality parameters in the menu to meet visual requirements. Traditional TVs make simple adjustments to picture quality based on brightness or chrominance information only. There is no distinction between dynamic and static images, and the setting of image quality parameters. When the image quality parameters cannot meet the customer's needs, it is necessary to adjust the image quality parameters multiple times according to different inpu...
