PURPOSE:To reproduce easily observable and beautiful image by checking the set position of an original at the time of prescanning, setting up an original frame part to an easily observable color and setting up a binary threshold corresponding to the floated part of the original. CONSTITUTION:A system processing part 4 previously detect the set position of an original at the time of prescanning, detects the original frame part of the original and sets up the density of image data in an image processing part 2. When the binary data of image data of a book to be an original are inputted from a binarizing processing part 13, a trimming processing part 3 automatically sets up a threshold capable of recognizing the original frame of an original programmed on a PROM 16 and a threshold capable of copying the floated part of the original and outputs a command signal such as 'forced white' and 'bianry/photographing' to a data switching circuit 10 through a DPRAM 14 under the control of a CPU 15. Consequently, an easily observable and beautiful image can be reproduced. |
