1. An image reading apparatus comprising:
- a scanner which relatively exposes a document, and which receives and outputs light beams reflected from the document;
a reader which comprises a plurality of color line sensors for reading a color image and having a plurality of reading elements aligned in a first direction, and a line sensor for reading a monochromatic image, the reader receiving the light beams output from the scanner;
a driving motor which moves the scanner in a second direction orthogonal to the first direction;
a reference member which is arranged in front of a leading edge of a reading face of the document, in the second direction; and
a controller which corrects image data on the document on the basis of data obtained by reading the reference member using the plurality of color line sensors,wherein a region in which the line sensor reads the reference member is in a region in which the plurality of color line sensors read the reference member.

Abstract
An image reading apparatus having a color line sensor and a monochromatic line sensor starts to read on the basis of the color reading start position when reading the image of a document in color and starts to read on the basis of the monochromatic reading start position when reading the image of a document in monochrome.

12. A method of reading an image, comprising:
-
relatively exposing, by a scanner, a document, and receiving and outputting light beams reflected from the document; reading, by a plurality of color line sensors of a reader and a plurality of reading elements of the reader aligned in a first direction, a color image based on the light beams output from the scanner, the scanner being driven in a second direction orthogonal to the first direction; reading, by a line sensor of the reader, a monochromatic image based on the light beams output from the scanner; and correcting, by a controller, image data on the document on the basis of data obtained by reading a reference member using the plurality of color sensors, the reference member arranged in front of a leading edge of a reading face of the document in the second direction, wherein a region in which the line sensor reads the reference member is in a region in which the plurality of color line sensors read the reference member. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
