| description | An image processing apparatus includes a memory and an estimation unit. The memory stores a color conversion model representing relations between plural colorimetric values obtained by performing, in plural color measurement directions, a color measurement of plural images formed on a first sheet using plural coloring materials including a luster coloring material, and coloring-material amounts used for the images for which the color measurement is performed and the color measurement directions for which the colorimetric values are obtained. The estimation unit estimates, on the basis of a colorimetric value, of a measurement target image formed on a second sheet of a type different from a type of the first sheet, obtained in a single direction and on the basis of the color conversion model, a colorimetric value, of the measurement target image, obtained in a case of performing a color measurement in a direction other than the single direction. |
