IMAGE READING APPARATUS, IMAGE FORMING APPARATUS, NON-TRANSITORY COMPUTER READABLE MEDIUM, AND METHOD

摘要

An image reading apparatus includes a reading unit that reads a plurality of colors in a document, a relative movement unit that causes the reading unit and the document to make a relative movement in a first scanning direction, and an output unit that outputs color information at an interval, the color information indicating whether the document read by the reading unit is chromatic, the interval being longer in the first scanning direction than a length in the first scanning direction of a color misregistration, the color misregistration being expected to occur in an image if a speed of the relative movement fluctuates owing to a unique performance characteristic of the relative movement unit, the image being obtained as a result of reading by the reading unit.

1. An image reading apparatus comprising:
a reading unit that reads a plurality of colors in a document; a relative movement unit that causes the reading unit and the document to make a relative movement in a first scanning direction; and an output unit that outputs color information at an interval, the color information indicating whether the document read by the reading unit is chromatic, the interval being longer in the first scanning direction than a length in the first scanning direction of a color misregistration, the color misregistration being expected to occur in an image if a speed of the relative movement fluctuates owing to a unique performance characteristic of the relative movement unit, the image being obtained as a result of reading by the reading unit.
