Abstract
In accordance with an embodiment, a first light source configured to emit visible light; a second light source configured to emit invisible light; and a light guide section configured to reflect the light emitted by the first light source and the second light source in a longitudinal direction towards a direction of a reading area of an image.
Claims19
A light source unit, comprising:
- a first light source configured to emit visible light;
- a second light source configured to emit invisible light;
- and
- a light guide configured to reflect the light alternately emitted by the first light source and the second light source based on an exposure time period in a longitudinal direction towards a direction of a reading area of an image.

An image processing apparatus, comprising:
- a light source unit comprising a first light source that emits visible light, a second light source that emits invisible light, and a light guide configured to reflect the light alternately emitted by the first light source and the second light source based on an exposure time period in a longitudinal direction towards a direction of a reading area of an image;
- and
- a CCD sensor configured to receive reflected light obtained by reflecting light emitted by the light source unit with a sheet to output the received result as an electrical signal.
An image processing system, comprising:
- a light source unit comprising a first light source that emits visible light, a second light source that emits invisible light, and a light guide configured to reflect the light alternately emitted by the first light source and the second light source based on an exposure time period in a longitudinal direction towards a direction of a reading area of an image;
- a CCD sensor configured to receive reflected light obtained by reflecting light emitted by the light source unit with a sheet to output the received result as an electrical signal;
- and
- an authenticity determination unit configured to determine information contained to electrical signal acquired from the CCD sensor.
