According to one embodiment, a video processing apparatus includes a histogram generator, a tone curve generator, a blend parameter generator, and a blending module. The histogram generator generates a histogram based on a luminance level of a pixel of a video signal. The tone curve generator generates a first tone curve which controls a luminance value of the video signal based on the histogram. The blend parameter generator generates a blend parameter for blending the first tone curve and a prescribed tone curve, based on the histogram. The blending module blends the first tone curve and the prescribed tone curve based on the blend parameter to generate a second tone curve.
