Abstract
An automatic backlight control system and a method thereof, for receiving and analyzing an image dataset to control the backlight module of a display device are provided. Firstly, a first backlight intensity value generated by using the analysis and control module to analyze a first frame data is stored in the storage module. Then, the analysis and control module generates a translation vector value according to a first vector component and a second vector component of an equivalent translation vector corresponding to a second frame data of the image dataset. When the translation vector value is smaller than the threshold value, the selection module transmits the first backlight intensity value to the backlight control module for controlling the backlight module according to first backlight intensity value. When the translation vector value is greater than the threshold value, the backlight control module controls the backlight module according to the second backlight intensity value.
