Abstract

The invention discloses a method and a device for generating Gamma files, relating to the technical field of a display and invented for improving the adjustment efficiency and accuracy of the Gamma data of the display. The method comprises the following steps of: transforming the original Gamma data obtained by calculation into Gamma data corresponding to the Gamma table of each chip according to the structure of the Gamma table of each chip; and generating the Gamma file of each chip according to the transformed Gamma data. The invention is mainly applied to televisions.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a method and device for generating a Gamma file. Background technique [0002] For display devices such as TVs and computers, its input voltage signal will produce luminance output on the screen. However, the brightness of the above-mentioned display device is not proportional to the input voltage signal, therefore, a kind of distortion will be generated. If the input is a black and white image signal, this distortion will darken the middle area of ​​the displayed image. If the input is a color image signal, this distortion will not only make the displayed image darker, but also shift the hue of the displayed image. Gamma is the brightness parameter of this distortion, which characterizes the corresponding relationship between the brightness output and the input voltage signal. [0003] In the prior art, in order to solve the problem of inconsistency in the gray scale and col...
