Abstract

PURPOSE:To realize a read with high quality by identifying an original by using reflection characteristic from infrared band to near-infrared band, and correcting signals corresponding thereto. CONSTITUTION:In a color original reader that reads a color original 1 and executes gamma-character correction, one or more original identifying detecting sensors 6 having light receiving characteristic in the extent from the near- infrared band including visible band to the infrared band are provided. The kind of the original is identified by using the sensor 6. In accordance with the result of this identification, at least gamma-characteristic suitable for the original is selected.
