Abstract

PURPOSE: To ensure an automatic reproduction of the picture suited for the manuscript pattern through a simple constitution, by providing two units of the image sensor in order to calculate the manuscript characteristics by the picture information output of the sensor featuring the higher sampling density and to allot the picture information output of the lower density sensor to the output picture element respectively.
CONSTITUTION: The picture along scanning line A-B covering manuscript 2 throughout is read out by 1st image sensor 8 via 1st optical system 6, and the picture along scanning line C'-D' of manuscript 2 is read out by 2nd image sensor 12 via 2nd optical system 10. The read sampling density of sensor 12 is set higher than that of sensor 8, and the characteristics of manuscript 2 is calculated based on the picture information read out through sensor 12. Based on the calculation result, the picture information delivered from sensor 8 is allotted to the output picture element.
