Abstract
An image processing apparatus includes a separation unit that separates a high-frequency component and a low-frequency component, a first generation unit that generates a color signal component from the low-frequency component, a second generation unit that generates a color signal component from the low-frequency component, a third generation unit that generates a color signal component used in common for a luminance signal and a chrominance signal, a first tone conversion unit that performs first tone conversion processing on an output of the third generation unit, a color-and-luminance separation unit that generates a luminance signal and a chrominance signal, a second tone conversion unit that performs a second tone conversion on the high-frequency component, and a combining unit that combines outputs of the color-and-luminance separation unit and the second tone conversion unit.
