Method and means for producing high quality digital reflection prints from transparency images

摘要

A method of digital photofinishing comprising the steps of: producing a digital color image having colorimetric tristimulus values describing a color transparency media from a color image captured on color transparency photographic media; first transforming the digital color image having colorimetric tristimulus values describing color transparency media to a digital color image having colorimetric tristimulus values describing a reflection print; second transforming the digital color image having colorimetric tristimulus values describing a reflection print into digital code values representative of the color image for printing by a digital color printer using a combination of 1D and 3D look up tables; sharpening the transformed digital code values representative of the color image with a sharpening algorithm optimized to avoid unacceptable artifacts; and digitally printing the sharpened digital color image onto reflection media. <IMAGE>
