ABSTRACT:
There is provided a method of applying colour correction to a video image obtained by scanning photographic film frames, in which each frame on the film is scanned a plurality of times to produce a plurality of constituent frames each containing only part of the data required to represent the image at a relatively high resolution, the constituent frames associated with each film frame are assembled to provide a relatively high resolution video image, and the high resolution images are stored and/or displayed. In the invention, information is stored indicating the relationship between each constituent frame and its associated high resolution image, a colour correction decision is made, and colour correction is applied to one or more of the constituent frames associated with that high resolution image.
