Image quality processing method and display equipment

Abstract

An embodiment of the invention discloses an image quality processing method and display equipment, which are particularly suitable for a social television. The method provided in the technical schemedisclosed by the embodiment of the invention comprises the following steps: allocating to-be-adjusted parameters through the difference of signal input ends on the premise of distinguishing the signalinput ends, and allocating the to-be-adjusted parameters to a wired video input through a first interface. directly adjusting the to-be-adjusted parameters of the wired video signal on the second chip so as to achieve an image quality processing effect of the wired video signal. For a first video signal input through a second interface, the second chip sends a first to-be-adjusted parameter to the first chip, so that the first chip generates a video signal sent to the second chip by the first chip according to the first to-be-adjusted parameter, and the second chip adjusts the video signal received from the first chip according to the second adjustment parameter, and finally sends the adjusted video signal to the display screen. Through the method, the problems of edge hooking and color distortion of the graphic layer signal in the image quality processing process are effectively prevented.

Description

[0001] This application claims the priority of the Chinese patent application with application number 201910498198.3 filed with the State Intellectual Property Office on June 10, 2019. The entire contents of which are incorporated by reference in this application. technical field [0002] The embodiment of the present application relates to display technology. More specifically, it relates to an image quality processing method and a display device. Background technique [0003] At present, since the display device can provide users with playback images such as audio, video, and pictures, it has attracted widespread attention from users. In recent years, user demands on display devices are increasing day by day. For example, a user wants to watch high-definition cable television through a display device, and sometimes a user wants to watch Internet TV through a display device. [0004] The video signal of the Internet TV can come from the network or from the USB. Generally...

Problems solved by technology

The set-top box chip does not process the image quality of the video signal before superimposing the video layer signal and the graphics layer signal, but directly mixes and superimposes the signal into an HDMI video signal, and the display device chip performs image quality processing on the signal input by the HDMI channel , because image quality processing involves chroma, definition, and noise reduction processing, and different video signals have different image quality processing effects, so the graphics layer signal of the set-top box will change color with different image quality processing , and even the outlining problem occurs due to the high noise reduction intensity
