Image capturing system and method of generating image data

摘要

An image capturing system includes an image capturing unit configured to photograph the medium on a medium installation face, a lighting configured to irradiate the medium installation face, a lighting control unit configured to control the lighting, and a non-readable area determining unit configured to determine whether there is a non-readable area from which the image capturing unit is unable to read information of the medium due to reflected light of the lighting. The non-readable area is determined based on an image acquired by photographing the medium in a turned-on state of the lighting. When the non-readable area determining unit determines that there is the non-readable area, the medium is photographed in different lighting states set by the lighting control unit, and among the image data generated in photographing process, image data corresponding to the medium is generated by synthesizing areas except an area corresponding to the non-readable area.

1. An image capturing system comprising:
a base unit arranged on a medium installation face on which a medium that is a reading target is installed; an arm unit extending upwardly 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 disposed in the top unit and configured to irradiate the medium installation face; a lighting control unit configured to control driving of the lighting; and a non-readable area determining unit configured to determine whether or not there is a non-readable area from which the image capturing unit is unable to read information of the medium due to reflected light of the lighting by the medium, based on an image corresponding to the medium that is acquired by performing a photographing process in a turned-on state of the lighting before image data of the medium captured by the image capturing unit is stored, wherein, when the non-readable area determining unit determines that there is the non-readable area, a lighting state of the lighting is set to be different by the lighting control unit, and the medium is photographed by the image capturing unit in states in which the lighting states are different from each other, and wherein, among the image data generated in each photographing process, image data corresponding to the medium is generated by synthesizing areas except for an area corresponding to the non-readable area.
