Abstract
There is a signal processing apparatus, including a gamma correction circuit that performs gamma correction on an input luminance signal and generates an output luminance signal, an output-to-input ratio calculation circuit that calculates a ratio of the output luminance signal to the input luminance signal as an output-to-input ratio of a luminance signal, and a color difference correction circuit that multiplies an input color difference signal by the output-to-input ratio of the luminance signal and generates an output color difference signal. As a result, by correcting the input color difference signal using the output-to-input ratio of the luminance signal, the output color difference signal in which color difference correction has been performed in view of influence of gamma correction can be generated.
