Abstract
An image processing apparatus of the embodiments includes: an input unit configured to input a hue signal representing a hue of an image and an image quality signal representing a texture of the image; a conversion unit configured to convert the image quality signal into a physical quantity signal indicating at least one physical quantity of a refractive index of a color material, surface roughness of an image, an area ratio of dots on an image surface, and a layer thickness of a color material in an image corresponding to the image quality signal; and a dot arrangement determination unit configured to determine a color material dot arrangement for outputting the image based on the hue signal and the physical quantity signal.
