Patent ID: 7843605

Claim:
A color processing apparatus comprising: a discriminator, arranged to discriminate a combination of a device type of a source device and a device type of a destination device; a transformer, arranged to transform a colorimetric value of a contact colorimeter into that of a non-contact colorimeter; and a color converter, arranged to perform color conversion using colorimetric values of the source device and colorimetric values of the destination device, wherein when said discriminator discriminates that a device of luminous type and a device of non-luminous type are combined, said transformer transforms colorimetric values of the device of non-luminous type measured by the contact colorimeter into those of the non-contact colorimeter, and said color converter performs the color conversion in accordance with a predetermined color matching method using colorimetric values of the device of luminous type measured by the contact colorimeter and the transformed colorimetric values of the device of non-luminous type.
