Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
96 words
A method of generating a representation of an image, the method comprising scanning a film (2) carrying an image to which the film has been exposed, and wherein during exposure the appearance of the image has been modified in accordance with a characteristic function of the film; obtaining signals (4,5,6) representing the colour component content of the image recorded on the film; modifying the signals with a function (11,10,8) constituting the inverse of the characteristic function of the film to produce a compensated image; and subsequently applying a chosen film characteristic function to the compensated image.
Claim 2
Dependent Claim
15 words
A method according to claim 1, wherein the scanned film (2) is a colour film.
Claim 3
Dependent Claim
74 words
Apparatus for generating a representation of an image (2) comprising scanning means (3) to scan a film (2) carrying an image to obtain signals (4,5,6) representing the colour component content of the image recorded on the film; modifying means (7) to modify the signals with a function(11,10,8) constituting the inverse of a film characteristic function to produce a compensated image; and means for subsequently applying a chosen film characteristic function to the compensated image.
Claim 4
Dependent Claim
23 words
Apparatus according to claim 3 wherein the modifying means comprise a log amplifier (7) and wherein the signals are converted to density signals.
