Based on a first table in which a value of an input luminance signal is corresponded to a value of an output luminance signal acquired by performing nonlinear correction processing on the input luminance signal, there is created a second table in which a value of the input luminance signal is corresponded to a value of a color correction signal for performing amplitude control based on the nonlinear correction processing performed on the input luminance signal on an input color signal. The nonlinear correction processing is performed on the input luminance signal based on the first table and the amplitude control is performed on the input color signal based on the second table.
