Abstract:
An image processing apparatus according an aspect of the present disclosure converts image signals indicating an image to output signals including signals corresponding to individual color components that an output device deals with by interpolation processing using a look-up table. The apparatus includes a first conversion unit and at least one second conversion unit. The first conversion unit converts the image signals to image signals corresponding to linearity of the signals corresponding to the individual color components. The at least one second conversion unit converts the image signals converted by the first conversion unit to the output signals by the interpolation processing.
