Abstract

The invention provides an image processing method and a television. The method comprises the following steps: a, receiving an instruction input by a user, and determining line frequency and field frequency of an output signal and an image initial position according to the number of rows or the number of columns required to be shielded input by the user, and line frequency and field frequency of an input signal; and b, comparing the line frequency and field frequency of the output signal and the image initial position and physical resolution of a display screen, and outputting the output signal to a position corresponding to the display screen. Through the technical proposal provided by the invention, the television can display images with 100 percent of fidelity factor, improves the definition of the images, and provides the user with better visual feeling.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to the technology of high-definition display processing of televisions. Background technique [0002] LCD high-definition TV is a TV with multiple audio-visual and auxiliary functions. The highest physical resolution of current LCD TVs can reach 1920*1080. Therefore, for playing DVDs in 1920*1080 format, theoretically point-to-point technology can be achieved. That is to increase the redisplay rate to 100%, so that users can experience the real high-definition quality enjoyment. [0003] At present, the physical resolution of high-definition screen (FULL HD PANNEL) is 1920*1080, and DVD outputting 1080I signal has become very popular, but because the output range of many DVDs is not large enough, if LCD TV uses 100% reproduction rate to display, users will You see unwanted sidebands appearing around the TV picture, such as figure 1 as shown, figure 1 The area...
