Abstract
Apparatus for interactively modifying an image represented by digital data defining the color component content of pixels of the image, comprises an image store for storing the said digital data; a display; look-up tables defining retouch curves for each color component; and a microprocessor for applying the image in the image store to the LUTs and thereafter to the display to display the retouched image. The microprocessor also enables an operator to modify the retouch curves so that a second selected image point is retouched to the color of a first selected image point by modifying a color component retouch curve for each color component used to define the original image such that a pixel located at the second selected point will be retouched to have the color content of a pixel at the first selected point.
