ABSTRACT:
An image compensation system and methods for video appliances to reproduce an optimum image, by judging exterior environment and by compensating for an original image by the judged exterior environment. According to the system and methods, a color sensor senses color of exterior lighting of an appliance, and provides electrical signals corresponding to color components of the sensed color. The signals are converted into a digital value by an analog-to-digital converter. A microprocessor judges the type of exterior lighting, by the digitized values, and searches for image compensation data according to the judged exterior lighting. It thereby makes a video processor compensate for an original image signal.
