Abstract
According to one embodiment, a knee correction device includes a generator, a detector, a mixer, and a calculator. The generator generates a luminance signal from R, G, and B color signals. The detector detects a color signal having a maximum value among the R, G, and B color signals. The mixer mixes the luminance signal generated by the generator and the color signal detected by the detector, at a predetermined mixing ratio. The supply module supplies a coefficient for performing level compression on each of the R, G, and B color signals, based on an output of the mixer. The calculator performs level compression on the R, G, and B color signals by subjecting the coefficient supplied by the supply module and the R, G, and B color signals to a calculation.
