ABSTRACT:
A method and circuit for controlling the brightness of a backlight in a display device. The circuit comprises a backlight brightness selecting block that measures the brightness of ambient light and selects brightness information of the backlight based on the measured brightness of the ambient light. An image processing block performs image processing on received image signal based on the measured brightness of the ambient light, and calculates an image processing gain of the received image signal based on the result of image processing and the received image signal. A backlight adjusting unit controls the brightness of the backlight based on the selected backlight brightness information and the image processing gain.
