PROCESS AND CIRCUIT FOR THE PARTIAL ELECTRONIC CORRECTION IN COLOUR IMAGE REPRODUCTION

摘要: In the method for improving drawing in colour image reproduction by partial electronic retouching, trichromatic sampling of a component provides components which are subjected to an analog/digital conversion and stored memory (1). With coordinate probe (50, 51, 52), retoucher will proceed same way as with retouching brush. By means probe, coordinates moving area on (surface brush) be retouched well number correction steps point searched. For marked corrections calculated point. The coloured or printing read (1) modified obtain effect under control monitor (2). individual values each step may freely selected. previously determining modifications so that they decrease from center towards edges (for example according Gauss distribution), there provided degree increases decreases progressively.
