ABSTRACT:
An image edit system comprises a write circuit for writing specific bits into areas about locations in a bit map memory in accordance with the coordinates of a plurality of points as entered by a coordinates entering unit, the locations in a bit map memory corresponding to the plurality of points, an image input unit for reading an image on an original by scanning the original, a read circuit for reading out the contents of the bit map memory in synchronism with the scanning by the image input unit, and a circuit for replacing the data of the image on the original with specific data or adding the specific data to the image data when the specific bits are read out of the bit map memory.
Specific bits are written into the bit map memory, in a pattern about the points designated by the coordinates entering unit. When the original image is scanned, the contents of the bit map memory are read out in synchronism with the scan. During the course of the reading operation, when the pattern is detected, an image of red, for example, is superposed on an image of the original.
