Method for realizing automatic adjustment of Gamma curve of television through computer

Abstract

The invention discloses a method for realizing automatic adjustment of a Gamma curve of a television through a computer, which is mainly characterized in that a user sets up picture quality indexes needing to be adjusted through a human-computer interface on the computer; meanwhile, the current practical Gamma data of the television is collected by the computer and is calculated through using a Gamma automatic adjustment algorithm; the calculated adjustment data is sent to a receiving end of the television; data information forwarded by the computer is timely received by the television through an RS232 interface and is decrypted; control contents of the computer, which mainly comprise red-green-blue (RGB) information of the Gamma curve, are responded according to contents of an information packet; and through repeated calculation and adjustment, the automatic adjustment of the Gamma curve of the television is finally realized. By adopting the method, the regulated Gamma curve has high transitivity, and has the characteristics of good adaptability, quick adjustment speed, high veracity and good safety.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a method for automatically adjusting the Gamma curve of a television through a computer. Background technique [0002] With the continuous improvement of people's living standards and the continuous advancement of technology, TV is an indispensable electronic consumer product in people's daily life. In order to obtain visual comfort, the quality of TV pictures needs to be further improved. And adjusting the Gamma curve is a very important improvement measure to improve the quality of the TV picture. Generally speaking, in order to improve the brightness, dynamic contrast ratio, color saturation and other indicators of LCD TVs and ensure image quality, adjusting the Gamma curve is a guarantee measure to achieve the above indicators. In the prior art, there are mainly two ways to use the Gamma curve. One is to directly use the original Gamma curve of the screen without adjustin...

Problems solved by technology

In the prior art, there are mainly two ways to use the Gamma curve. One is to directly use the original Gamma curve of the screen without adjusting the Gamma curve. In this way, the picture quality cannot be guaranteed, and the picture quality of the TV image is very poor; One way is to adjust the Gamma curve, but the method is manual adjustment, which results in a slow debugging speed, resulting in many debugging steps during TV production, long adjustment time, and low production efficiency
