Abstract
A projector includes a light sensor, a micromirror device, a light source and a processor. The light sensor senses an ambient brightness. The micromirror device is controlled by a duty cycle. The light source is controlled by a driving current. The processor receives an image including a plurality of non-black pixels. When a brightness of at least one of the non-black pixels is lower than the ambient brightness, the processor increases one of the duty cycle and the driving current. When the brightness of at least one of the non-black pixels is still lower than the ambient brightness after adjustment, the processor increases another one of the duty cycle and the driving current. When the brightness of at least one of the non-black pixels is still lower than the ambient brightness after adjustment, the processor performs an image processing process for the brightness of the non-black pixels.
