Color matching profile generating device, color matching system, color matching method, color matching program, and electronic apparatus
View Patent ↗Aspects of the invention provide a color matching profile generating device that, in an apparatus having an input device and an output device, performs a color matching for the input device and the output device and reproduces favorable colors without depending on color characteristics of the devices. The color matching profile generating device can use an input device profile and an output device profile, in addition to a color conversion profile which defines color conversion characteristics in an absolute color space and generates a color matching profile for the input device and the output device. Since the color conversion profile defines the color conversion characteristics in the absolute color space, color conversion can be performed to image data obtained from the input device without depending on characteristics of the input device. Accordingly, by performing a color matching process with the generated color conversion profile, image data can be output with color characteristics determined in the absolute color space, irregardless of characteristics of the output device.
1. A color matching system comprising:
a profile memory unit that stores a plurality of color matching profiles for an input device and an output device during use according to deterioration with time of at least one of the input device and the output device;
a color matching processing device that performs a color matching process on image data, that is supplied from the input device, using one of the plurality of color matching profiles to output the result to the output device; and
an updating device that detects a used period of at least one of the input device and the output device and selects one of the plurality of color matching profiles based on the detected used period, if necessary, for performing an update process which updates the color matching profile used by the color matching processing device,
the updating device deleting the color matching profile corresponding to an expired used period, from the profile memory unit.
2. The color matching system according to claim 1 ,
the updating device performing the update process after a power supply is applied to the input device and the output device.
3. The color matching system according to claim 1 ,
the updating device performing the update process at predetermined times.
4. An electronic apparatus, comprising:
a color matching system as recited in claim 1 ;
an input device; and
an output device, which are associated with each other.
