    • 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.

    • An overhead image reading apparatus 1 includes: an image-capturing unit 22 that captures an image of a medium S to be read from above when the medium S to be read is placed on a placement surface 2; a light source 21 that irradiates the medium S to be read with light when the image-capturing unit 22 captures the image of the medium S to be read; and a light blocking portion 25 that blocks light above an upper-end position of light emitted from the light source 21. As a result, the user 100 can be prevented from seeing light from the light source 21 with his/her eyes and from being dazzled with an unpleasant feeling by light from the light source 21 during reading on the medium S to be read.
    • 顶置图像读取装置1包括:图像拍摄单元22,当要读取的介质S放置在放置表面2上时,捕获从上方读取的介质S的图像; 当图像拍摄单元22捕获要读取的介质S的图像时,照射用于读取的介质S的光源21; 以及阻挡从光源21发射的光的上端位置以上的光的遮光部25。结果,可以防止用户100用眼睛看到来自光源21的光,并且不会 在读取要读取的介质S上时,来自光源21的光感到令人不愉快的感觉。

    • Embodiments of systems and methods for directly reading and verifying characters on a personalized document, are provided. A surface of the personalized document is illuminated independently or simultaneously by first and second light sources. The first light source has a ring shape, surrounds the personalized document in 360 degree, and transmits a grazing incident light to illuminate the surface of the personalized document. An incident light from the second light source is reflected by a beam splitter and illuminates the surface of the personalized document in a direction generally perpendicular to the surface. Light reflected from the surface of the personalized document in a direction generally perpendicular to the surface thereof is collected by a camera.
