Abstract
A method and apparatus for interactively modifying an image defined by original digital data, representing the color content of pixels of the image at a first resolution. The apparatus comprises a first store (4;12) for storing the digital data of the pixels at the first resolution; a monitor (9); a digitizing table (5); and an image processor (6;13,15). The image processor (6;13,15) is responsive to signals from the digitizing table (5) to select a modification algorithm and a portion of the image stored in the first store (4;12) to which the algorithm is to be applied. The image processor is further adapted to modify a subset of pixels of the image portion in accordance with the selected algorithm and to cause the modification image portion to be displayed on a monitor (9) at a second, lower resolution under the control of the modified pixels, and to modify and display successive subsets of the high resolution pixels while the same image portion and algorithm are selected and until all the high resolution pixels within the selected portion have been modified.
