Abstract
Abstract A method for correcting for exposure in a digital image which was captured by an image capture device and which is to be printed on a printer which forms monochrome or color images, on a medium, includes providing a plurality of exposure and tone scale correcting nonlinear transforms, each such nonlinear transform being unique to an exposure condition and which corrects exposure and tone scale for a digital image captured by the capture device for such unique exposure conditions and to be printed by the printer; and selecting the appropriate nonlinear transform from the plurality of nonlinear transforms and using such selected transform to transform the digital image and produce a new digital image which is corrected for exposure and tone scale when printed from the printer.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
128 words
A method for correcting for exposure in a digital image which was captured by an image capture device and which is to be printed on a printer which forms monochrome or color images, on a medium, comprising the steps of: a) providing a plurality of exposure and tone scale correcting transforms, each such transform being unique to an exposure condition and which corrects exposure and tone scale for a digital image captured by the capture device for such unique exposure conditions and to be printed by the printer; and b) selecting the appropriate transform from the plurality of transforms and using such selected transform to transform the digital image and produce a new digital image which is corrected for exposure and tone scale when printed from the printer.
Claim 2
Independent Claim
128 words
A method for correcting for exposure in a digital image which was captured by an image capture device and which is to be printed on a printer which forms monochrome or color images, on a medium, comprising the steps of: a) providing a plurality of exposure and tone scale correcting transforms, each such transform being unique to an exposure condition and which corrects exposure and tone scale for a digital image captured by the capture device for such unique exposure conditions and to be printed by the printer; and b) selecting the appropriate transform from the plurality of transforms and using such selected transform to transform the digital image and produce a new digital image which is corrected for exposure and tone scale when printed from the printer.
Claim 3
Independent Claim
