Abstract
An object of the present invention is to realize to excellently perform a color matching process among media having different white points. To achieve the above object, a colorimetry value of a sample is corrected on a human's color perception space on the basis of a media white point in case of creating transformation data used in transformation performed between data on a color space depending on a device and data on a color space not depending on a device, and the transformation data is created on the basis of the corrected colorimetry value.
Claims9
An image processing method of creating transformation data used in transformation performed between data on a color space depending on a device and data on a color space not depending on a device,
- wherein a colorimetry value of a sample is corrected on a human's color perception space on the basis of a media white point, and the transformation data is created on the basis of the corrected colorimetry value.
An image processing method of creating transformation data used in a color matching process executed between a source device and a destination device,
- wherein a white point correction for transforming colors on media at the source device side to colors on media at the destination device side is performed on a human's color perception space on the basis of white points on media at the source device side and white points on media at the destination device side.
A recording medium for recording a program of realizing an image processing method of creating transformation data used in transformation performed between data on a color space depending on a device and data on a color space not depending on a device,
- wherein a colorimetry value of a sample is corrected on a human's color perception space on the basis of a media white point, and a program for creating the transformation data on the basis of the corrected colorimetry value is recorded.
A recording medium for recording a program of realizing an image processing method of creating transformation data used in a color matching process executed between a source device and a destination device,
- wherein a program for performing a white point correction for transforming colors on media at the source device side to colors on media at the destination device side on a human's color perception space on the basis of white points on media at the source device side and white points on media at the destination device side is recorded.
