Abstract

PURPOSE: To enable sculpturing to be achieved at the best contrast at all times, by putting into memory of an output at the time when a light detector's input is zero so as to eliminate drifting temperature of the light detector and also by conducting a scan on an entire surface of a manuscript at the light detector prior to start of sculpturing.
CONSTITUTION: An output at the time when a light source is turned off and an input of a light detector 1 is zero, is memorized by an integral memory 4 by turning off a switch S so that this temperature drift can always be eliminated from a signal level obtained from scanning of a manuscript's surface by the light source. Prior to start of sculpturing, an entire surface of a manuscript is scanned by closing switches S2 and S3, the lowest and the highest levels of an output of the light detector 1 during the scanning time are memorized by a memory 7 and a memory 8, a variable amplifier 10 to amplify a difference between the levels is adjusted so that the output becomes equal to the level corresponding to white portion of a sculptured image and, after sculpturing was started, sculpturing is performed by an output by a difference between the output of the light detector 1 and the lowest level value in the memory.
