Abstract: An image processing apparatus includes a signal input converter, a color gamut converter, a blend coefficient setter, and a color synthesizer. The signal input converter converts input signals having a first color gamut representing image data to first image signals that are at least substantially linear. The color gamut converter converts the first image signals to second image signals having a second color gamut narrower than the first color gamut. The blend coefficient setter sets a blend coefficient corresponding to a synthesis ratio of the first and second image signals based on saturation obtained from the input signals. The color synthesizer generates synthesized image signals obtained by synthesizing the first and second image signals at a ratio according to the set blend coefficient.

Abstract: An image processing device includes a hue changer and a color gamut converter. The hue changer changes a hue of input image data from a first hue to a second hue by combining a phase with a hue of a primary color when the input image data is at or adjacent the primary color, the phase being based on a hue angle phase difference between a first color gamut and a second color gamut narrower than the first color gamut. The color gamut converter preserves a hue about image data from the hue changer and converts a color gamut from the first color gamut to the second color gamut.
