Abstract
Disclosed is a video processing apparatus including: a brightness adjusting part which adjusts the brightness of a whole portion of a received video signal according to a brightness adjusting value; and a brightness stretching part which calculates gradient values to stretch a first brightness in a first portion including a smaller brightness value than a first reference value and a second brightness in a second portion including a larger brightness value than a second reference value in the received video signal, and outputs the received video signal having the brightness adjusted by the brightness adjusting part in a third portion including a smaller brightness value than a minimum brightness value and in a fourth portion including a larger brightness value than a maximum brightness value in the received video signal by applying the calculated gradient values to the third portion and the fourth portion, respectively, to display the brightness of the received video signal corresponding to the third portion and the fourth portion.
