Abstract
The continuity of at least one image characteristic, such as color, is maintained through image creation, processing and distribution by correlating that characteristic to a frame of reference. During a first processing operation such as image capture, an initial image decision list is generated indicative of at least a one change in at least one characteristic of an image adjusted during that operation. At the completion of that operation, the image is transformed to emulate a film print that serves as the reference for subsequent operations. In this way, the initial image decision list can be modified list to further adjust of the at least one characteristic of the image using the emulated film print during a second image processing operation.
Claims18
A method, using at least one processor to perform the steps of:
- (a) generating an initial image decision list indicative of at least a one change in at least one characteristic of an image adjusted during a first image processing operation;
- (b) transforming the image to emulate a film print;
- and
- (c) modifying the initial image decision list to further adjust of the at least one characteristic of the image in accordance with the emulated film print during a second image processing operation to substantially normalize the modified image decision list relative to the initial image decision list.
Apparatus comprising:
- an image decision list data entry device for entering an initial image decision list indicative of at least a one change in at least one characteristic of an image adjusted during a first image processing operation;
- and
- first processing means for transforming the image to emulate a film print;
- and
- second processing means for modifying the initial image decision list to further adjust of the at least one characteristic of the image in accordance with the emulated film print during a second image processing operation to substantially normalize the modified image decision list relative to the initial image decision list.
