Picture processor

Abstract

Abstract PURPOSE:To easily execute a prescribed picture processing independently of a black/white original or a color original by detecting a color marker on a multi-color original and applying the processing of a different picture in the marker region or at the outside of the region surrounded by the color marker. CONSTITUTION:Color separation is applied before binarization. A color code (designation of red, blue, black for marker) and density information are stored to an address given by picture data VR and VC in the color separation map. A color code data obtained by scanning the color marker is fed to a region extraction 500A and obtained marker signals RP, BP are fed respectively to the pre-processing circuit and the pre-processing is applied so as to form a marker signal with fidelity to the designated region. Then a gate signal S for extracting a density data formed based on the region signal representing the designated region (a) is outputted at every scanning line together with the color code data.
