Abstract: Image data is processed by identifying a region of substantially constant color within a first image. Color variations, in terms of standard deviation about an average color, are analyzed and a similar level of variation is applied to a second image. The first image may be derived from cinematographic film, with color 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.

Abstract: Displayed picture points are re-locatable in response to manual operation of an interface device such as a stylus or a mouse etc. The interface device is activated, by being placed into pressure or by clicking, and an identified picture point is subsequently moved in response to manual operation of the interface device. In response to said picture point being moved, other picture points are also moved by a displacement which differs from the displacement of the identified picture point and which varies in proportion to the original distance of the other picture point from the identified picture point.

Abstract: The present invention relates to a method and apparatus for removing unwanted movements in digitized image caused by unsuitable camera mountings or recordings made under difficult conditions. The image data is processed by tracking a selected image portion over a plurality of frames. The position of the image within its frame is adjusted so that the position of the selected image portion remains substantially constant frame after frame, and modifications to the image are made. Portions of the images that extend beyond frame edges are repositioned within the frame edge. The position of the image within its frame is then reset to its original position, so that the modified image moves as if it were part of an original shot.
