US 2010/0165419 A1 · IMAGE READING DEVICE AND IMAGE READING METHOD

Abstract

An image reading device 1 includes an output acquiring unit 21 acquiring outputs from a plurality of light receiving elements 17 arranged to form an image reading surface for reading an image of an original, a difference detecting unit 22 detecting edges in the original or an end portion of the original on the basis of the outputs from at least some of the light receiving elements 17 in the outputs acquired by the output acquiring unit 21, and an image information generating unit 23 generating the image information of the original by use of the outputs from the plurality of light receiving elements 17 when the difference detecting unit 22 detects the edges or the end portion of the original.

Dependent claims

An image reading device comprising:

an output acquiring unit to acquire outputs from a plurality of light receiving elements arranged to form an image reading surface for reading an image of an original;
a difference detecting unit to detect that a predetermined or higher level of difference exists between the outputs from at least some of said light receiving elements in the outputs acquired by said output acquiring unit;
and
an image information generating unit to generate the image information of the original by use of the outputs related to the detection or the outputs acquired within a predetermined period of time since the detection thereof from said plurality of light receiving elements when said difference detecting unit detects the predetermined or higher level of difference.
