IMAGE CAPTURING SYSTEM

摘要

An image capturing system includes an image capturing unit to photograph a medium placed on a medium installation face, a lighting unit disposed in a top unit to irradiate the medium installation face, a lighting control unit to perform driving control of the lighting unit, a scan instruction unit to issue an instruction to perform scanning to photograph the medium and to generate image data of the medium, and a non-readable area determining unit to determine whether or not there is a non-readable area based on an image of the medium obtained by photographing the medium with in a turned-on state of the lighting unit. When there is the non-readable area, the scanning is performed by turning off the lighting unit when the lighting unit was in a turned-on state, and when there is not the non-readable area, the scanning is performed in the turned-on state of the lighting unit.

1. An image capturing system comprising:
a base unit arranged on a medium installation face on which a medium to be read is placed; an arm unit extending upward from the base unit; a top unit extending from the arm unit so as to face the medium installation face; an image capturing unit configured to photograph the medium; a lighting unit disposed in the top unit and configured to irradiate the medium installation face; a lighting control unit configured to perform driving control of the lighting unit; a scan instruction unit configured to issue an instruction to perform scanning to photograph the medium by the image capturing unit, and to generate image data corresponding to the medium; and a non-readable area determining unit configured to determine whether or not there is a non-readable area at which information from the medium is unable to be read by the image capturing unit due to reflection of light that is emitted from the lighting unit and reflected at the medium, based on an image corresponding to the medium obtained by photographing the medium in a turned-on state of the lighting unit, after the instruction to perform scanning is issued and before the image data is generated, wherein when the non-readable area determining unit determines that there is the non-readable area, the scanning is performed by turning off the lighting unit by the lighting control unit when the lighting unit is in a turned-on state, and when the non-readable area determining unit determines that there is not the non-readable area, the scanning is performed in the turned-on state of the lighting unit.
