Abstract
A scanner has a first mirror having a plurality of concavities configured to reflect light from a document; and a sensor configured to detect light reflected by the concavity; the concavity having an optical characteristic that differs according to position.
Claims6
A scanner comprising:
- a first mirror having a plurality of concavities configured to reflect light from a document;
- and
- a sensor configured to detect the light reflected by the concavities, wherein
- an optical characteristic of the light reflected by the concavities differs according to positions at which the light is reflected on the concavities of the first mirror, and
- a spatial frequency characteristic of the light reflected by the concavities differs according to positions at which the light is reflected on the concavities of the first mirror.

A method of generating scanning data using a sensor configured to reflect light from a document by a first mirror having a plurality of concavities, and detect the light reflected by the concavities, comprising:
- detecting the light which is reflected by the concavities and whose optical characteristic, spatial frequency characteristic or focal length differs according to positions at which the light is reflected on the concavities of the first mirror, and generating scanning data by the sensor.
