ABSTRACT:
A display apparatus with a brightness control function is provided, in which a camera portion generates a first detection signal in an image mode by capturing an image of an object by an image sensor according to a first control signal and generates a second detection signal in an illumination mode by detecting external illumination by the same image sensor according to a second control signal. The display displays an image signal, and a controller provides the first control signal to the camera portion in image detection mode, and provides the second control signal to the camera portion in illumination detection mode to control brightness of the display based on the second detection signal received from the camera portion. Only part of the pixels of the image sensor can be used in the illumination detection mode so that additional parts are not required to provide automatic illumination control.
