Claim:
1. An image processing device, comprising: a color correction section that is input with an RGB signal, and performs color correction on the RGB signal; a YC conversion section that converts the color corrected RGB signal to a first brightness signal and a color difference signal; a Y conversion section that is input with the RGB signal, and generates a second brightness signal from the RGB signal; a processor configured to execute a process, the process comprising computing a first ratio at which to combine the first brightness signal and the second brightness signal based on the RGB signal; and a combining section that combines the first brightness signal and the second brightness signal at the computed first ratio, wherein, in cases in which the first brightness signal and the second brightness signal that are combined by the combining section are signals prior to gamma correction, the first ratio is computed based on a first ratio table including a relationship such that a second ratio of the second brightness signal to the first brightness signal increases as a level of the first brightness signal increases, and, in cases in which the first brightness signal and the second brightness signal that are combined in the combining section are signals after the gamma correction, the first ratio is computed based on a second ratio table that is different from the first ratio table.
