Abstract

PURPOSE: To automatically generate the image region signals directly from the image signals by reading out the storage contents of the image signal region for picture element patterns according to the picture element patterns formed by the masked image signals.
CONSTITUTION: The image signals formed by the binary signals from a scanner are inputted to each one line and the binary signals of the picture element signals from the specified number of upper and lower lines including the specified line are accumulated in a storage part 2. When the high level values of these accumulated binary picture element signals are masked with the specified patterns through a mask operating part 3, the halftone region signals and sentence region signals corresponding to the picture element patterns such as of photographs by which the periodically changing binary signals and the binary signals of continuous flow are identified and the image signal region contents for the picture element patterns stored in an image region signal generating part 5 are read out and the directly corresponding image region signals are automatically generated from the image signals through a correction part 7.
