Embodiment Construction

[0025] The basic principle of the present invention is to carry out statistics on the gray levels of all pixels of a frame image, find out the key area of ​​image distribution in this frame image, then determine the compensation curve of the video image according to the area, and adjust the video image according to the video compensation curve. The data is compensated, and the backlight adjustment coefficient is determined according to the video compensation curve, and then the backlight brightness is dynamically controlled in combination with the average brightness of the frame image.

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings, please refer to the principle diagram of video image dynamic processing shown in FIG. 1 . Firstly, the video data is analyzed, and the backlight adjustment coefficient is determined according to the video compensation curve in a frame of image, and then the backlight brightness is dynam...

Abstract

The invention discloses a processing method for determining the grey level distribution of video images and a method of dynamic processing of video images. The processing method for determining the grey level distribution of video images comprises the following steps: equally dividing the grey level of a frame video signal to multiple zones; calculating the pixel quantity of a frame video signal in each grey level zone; and determining the grey level distribution of the video image. The invention overcomes the disadvantages of the prior art, can dynamically reduce the backlight brightness without changing the brightness of the majority of the image, can reduce the energy consumption of liquid crystal TV while, and provides better visual effect to the television viewer.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular, to the technology of liquid crystal display video image processing. Background technique [0002] At present, most of the shortcomings of LCD TVs have been solved, and they are rapidly entering our lives. For example, the response time of LCD TVs is fast enough, and the viewing angle is large enough to initially meet the viewing requirements. [0003] But existing LCD TV still has some unsatisfactory places, for example no matter what signal the video image is, the power consumption of LCD TV is the same; The picture has a large luminous flux, and long-term viewing will cause visual fatigue. [0004] Because the general video image brightness is low, the load is 30% to 50% full white screen; if it is a movie and other screens, the brightness is lower, the general load is less than 30% full white screen, in this screen, if the backlight is fully bright , whi...
