Abstract:
An image processing method for processing a color image data having a plurality of color signals which are input successively, said method comprising the steps of:determining whether an output of said color image data is capable of being controlled and outputting an indication signal indicative of said capability;storing, in first and second sets of line memories, said plurality of color signals except a last color signal, each stored color signal being stored separately in a respective line memory in both sets of line memories;extracting, from the second set of line memories, a specified pattern from a restored color image which is formed by combining said plurality of color signals when said last color signal is input;matching said specified pattern against a reference pattern to obtain a matching result; andcontrolling said output of said color image data from the first set of line memories depending on said matching result if said indication signal indicates that the output of said color image data is capable of being controlled.
