Abstract
A video processing apparatus includes an input unit to which a video signal containing content is input, a first detector which detects a color of light in the surroundings, a second detector which detects whether a pattern portion formed of a single color of black or white is contained in the video signal input to the input unit, a corrector which corrects the video signal input to the input unit, and a controller. The controller conducts control so that the corrector corrects the video signal input to the input unit according to the color of light detected by the first detector if the second detector detects that the pattern portion formed of the single color of black or white is contained in the video signal input to the input unit.
