Image capturing device, color measurement apparatus, and image forming apparatus |
摘要 |
An image capturing device includes: a two-dimensional image sensor that captures an image of a predetermined image capture area including a subject; a light source that illuminates the image capture area; and a light blocking member that blocks light traveling from the light source toward a specular reflection position, the specular reflection position being a position that is in the image capture area and where, if light travels from the light source, the light would be specularly reflected to the two-dimensional sensor. The light blocking member is arranged outside the image capture area. |

1. An image capturing device, comprising:
a two-dimensional image sensor that captures an image of a predetermined image capture area including a subject; a light source that illuminates the image capture area; and a light blocking member that blocks light traveling from the light source toward a specular reflection position, the specular reflection position being a position that is in the image capture area and where, if light travels from the light source, the light would be specularly reflected to the two-dimensional image sensor, wherein the light blocking member is arranged outside the image capture area, and the light blocking member is arranged at a position overlapping with the light source as viewed along an optical axis direction of the two-dimensional image sensor. |
