Abstract
A color correction structure for a color imaging device in which a document is scanned in a predetermined direction by a slit exposure light. A light reflected on the document is lead to a photoconductive member along an optical path, and an image of the document is focused on the photoconductive member by a focusing lens which is arranged in the optical path. The color correction structure is provided with a plurality of filter members each transmitting reflected light having a predetermined wavelength, and at least one actuator for actuating the filter members in a direction substantially perpendicular to an extending direction of the slit exposure light, between a first position where the filter members are retracted from the light path and a second position where the filter members interferes with the light path. A controller controls the actuator for brightness and hue adjustments.
