COLOR COPYING MACHINE

摘要

PURPOSE:To prevent the same color on an original from coming to be a partially different color by setting automatically a binary level so that the level of three primary colors corresponding to the color designated by a user cannot be close to a binary threshold. CONSTITUTION:The color image on an original is read by an image sensor 1 and outputted to a binary device 4. A binary level calculating means 3 responds to a selecting color designated by a selecting color designating switch 2, automatically calculates the binary level and outputs it to the binary device 4. The binary level is calculated so that the color designated by a user cannot be close to the binary threshold level. The binary device 4 binarizes a three primary colors signal inputted based upon the abovementioned binary level and supplies it to a printing signal generating machine 5.
