Abstract
A luminance compensation apparatus and method applied to an electronic apparatus are disclosed. The luminance compensation apparatus includes an environment detector, a processor, and a luminance compensation unit. The environment detector is for detecting environment luminance and outputting a luminance detection value accordingly. The processor is coupled to the environment detector for outputting a compensation parameter according to the luminance detection value. The luminance compensation unit is coupled to the processor for compensating luminance values of pixels of the multimedia data according to the compensation parameter and outputting compensated multimedia data. The method includes detecting environment luminance and obtaining a luminance detection value accordingly; generating a compensation parameter according to the luminance detection value; and compensating luminance values of pixels of the multimedia data and providing compensated multimedia data according to the compensation parameter.
