Abstract
Image data is processed by identifying a region of substantially constant colour within a first image. Colour variations, in terms of standard deviation about an average colour, are analysed and a similar level of variation is applied to a second image. The first image may be derived from cinematographic film, with colour variations due to film grain. The second image may be a video image or a computer generated image and the application of a similar level of variation may reproduce noise similar to that present within the film due to grain. In this way, it is possible to add grain to non-filmed images so as to match said images to images derived from film.
