PREVIEW BUFFER FOR ELECTRONIC SCANNER

The invention provides an apparatus for enhancing full color images and may be used within a variety of computer peripheral devices such as a scanner which scans images initially recorded on a photographic medium, for example. The invention takes image data and applies a programmable set of parameters to the image data which govern color saturation and sharpness, inter alia. The image is then passed to a computer where a user may alter the parameter. The parameters are passed back to be reprocessed within the scanner and an updated image is then sent back the computer in real time.
