Patent ID: 7542621

Claim:
A method of simulation of a recording support rendering called target rendering, comprising the following successive steps: a) the digitization of images captured on a first support and at least one sensitometry control recorded on the same support, so as to obtain initial digital codes (x) for a set of pixels taken in the images and sensitometry control, b) the establishment, from the digital codes of the sensitometry control, of at least one initial sensitometry relationship for the first support, the initial sensitometry relationship linking the digital codes to the support's light exposure values, c) the establishment, from at least one target sensitometry relationship, corresponding to the target rendering, of new digital codes (x′) for a plurality of image pixels, the new digital codes being established so that the new digital code (x′) and the initial digital code (x) of each pixel are linked to the same exposure value (e), respectively by the target sensitometry relationship and the initial sensitometry relationship.
