MONITORING CAMERA
First Claim
1. A monitoring camera comprising:
- an image capturing unit configured to capture an image of a subject therein, said image capturing unit having an image capturing field angle adjustable by a zooming optical system;
a light source including a light emitting diode configured to emit an illuminating radiation;
a lens unit configured to apply said illuminating radiation in a direction which is substantially identical to a direction in which said image capturing unit captures the image; and
an irradiation moving unit configured to variably set an irradiation range of said illuminating radiation to irradiate an area which is substantially the same as said image capturing field angle of said image capturing unit.

Abstract
A monitoring camera is provided. The monitoring camera includes an image capturing unit configured to capture an image of a subject therein, the image capturing unit having an image capturing field angle adjustable by a zooming optical system; and a light source having a light emitting diode configured to emit an illuminating radiation. The camera further includes a lens unit configured to apply the illuminating radiation in a direction which is substantially identical to a direction in which the image capturing unit captures the image; and an irradiation moving unit configured to variably set an irradiation range of the illuminating radiation to irradiate an area which is substantially the same as the image capturing field angle of the image capturing unit.
