An image signal processor includes a controller configured to generate a red output signal, a green output signal, a blue output signal and a fourth color output signal in accordance with image input signals. A fourth color light component enables to reproduce a color outside the range of a color reproducible by the red light component, the green light component and the blue light component. The controller generates the fourth color output signal on the basis of a reference signal corresponding to a color different from a complementary color of a color reproduced by the fourth color light component.
