Abstract:
An image capturing unit includes a sensor section that images a predetermined range including a subject; a reference chart section that is imaged by the sensor section with the subject; and an illumination light source that illuminates the subject and the reference chart section. The illumination light source is arranged at a position where a mirror reflection region that mirror reflects light entering from the illumination light source to the sensor section is outside a region of the subject and the reference chart section.
