Abstract: An electronic image processing system includes a scanner in which a light source is provided to illuminate an image captured on a film. A charge-coupled device produces digital data defining a multiplicity of picture elements which together represent the image. A look up table converts the data from the CCD into a format suitable for processing by a processor which data is stored in a framestore. The data in the framestore is read and processed by the processor and output for display of the image on a monitor. Characteristics or attributes of the displayed image are adjusted by the processor in response to user manipulation of a stylus and touch tablet device. Once the user is satisfied with the image as displayed the adjustment is used to alter the manner in which the scanner and look up table operate so that a further scanning of the image will provide data in the framestore representing the image with characteristics or attributes similar to those in the previously displayed image.

Abstract: An image processing apparatus (1) comprises a color image scanner (2) for producing digital data defining pixels representing an image in terms of cyan (C), magenta (M), yellow (Y) and black (K) components. The CMYK data from the scanner is received by a conversion processor (5) and a color converter (6). The color converter (6) together with a format converter (7) converts the CMYK data into RGB data, representing the image in terms of its red, green and blue components, for processing by a drawing processor (9). The operation of the scanner (2) is adjustable to a desired setting to provide CMYK data to which a color correction has been applied. In order that the RGB data accurately represents the color content of the image the effect of the color correction must be removed.
