Abstract
A color image reading apparatus includes a plurality of linear sensors, each capable of generating plural analog color component signals. The sensors are arranged to read a line of the color image in a divided manner and such that adjacent ones of the linear sensors read mutually different lines of the color image. Also provided is a separator for separating the plural analog color component signals generated by the sensors into analog color component signals of each color, and a converter for converting the analog color component signals of each color into digital color component signals of each color, respectively. The apparatus further includes a device for forming plural continuous digital color component signals representing a line of the color image from the digital color component signals of each color converted by the converter. In addition, a processor is provided for digital color processing of the plural continuous digital color component signals to form digital color image signals usable for reproduction of the color image.
