Abstract
To realize downsizing. This invention provides an imaging apparatus with an irradiation means for irradiating a body with irradiation light stronger than light in the air coming to the body, a solid imaging element for performing photoelectric conversion on a pattern light of unique tissues obtained through the body, and a sensitivity adjustment means for adjusting the imaging sensitivity of the solid imaging element to the unique tissues by limiting the amount of a signal which is stored per unit time through the photoelectric conversion in the solid imaging element.
Claims26
An imaging apparatus, comprising:
- irradiation means for irradiating a body with irradiation light;
- a light detecting unit configured to detect an intensity of ambient light coming to the body;
- a light source control unit configured to control the irradiation means to irradiate the body with the irradiation light, having an intensity stronger than the ambient light coming to the body, based on the detected intensity of the ambient light coming to the body;
- a solid imaging element for performing photoelectric conversion on pattern light of unique tissues obtained through the body;
- and
- sensitivity adjustment means for adjusting an imaging sensitivity of said solid imaging element to the unique tissues by limiting an amount of a signal stored per unit time through the photoelectric conversion in said solid imaging element.
