A video processor includes a receiving section that receives video information representing video images and luminance-related information on the luminance of the video images and a video processing section that determines an expansion target luminance range of the video images based on the luminance-related information and expands the expansion target luminance range in such a way that the maximum luminance in the expansion target luminance range increases.

Video processor, display apparatus, and video processing method

A projector includes: a first processor that controls the projector; a second processor that controls the light source; and a storage unit that stores parameters for the second processor to control the light source. The second processor starts to control the light source based on the parameters stored in the storage unit when activated. When the parameters are changed, the first processor stores the changed parameters in the storage unit.
