Abstract
An image processing device comprising: a conversion unit to receive a first input signal including first color information, a first color being reproduced at pixels on the basis of the first color information, the first input signal including first color information obtained from an input image signal corresponding to a red component, a green component and a blue component, to specify saturation of the first color, and configured to obtain luminance attenuation ratio on the basis of a relationship previously stored between saturation and luminance attenuation ratio, and the saturation of the first color, and to output a second input signal including second color information whose luminance is decreased from the first color information on the basis of the luminance attenuation ratio corresponding to the first color information; and a signal processing unit configured to output an output signal for driving the pixels on the basis of the second input signal.
