PROBLEM TO BE SOLVED: To provide an image whose sufficient image quality is secured even if an object is photographed by using photographing auxiliary light whose irradiation light volume is uneven.SOLUTION: While an imaging sensor 3 periodically images a subject, an LED 21 is caused to emit light and the subject is irradiated with photographing auxiliary light whose irradiation range is enlarged by a light emission lens 23. During that time, a main CPU 2 controls a light emission amount of the LED 21 to a light volume corresponding to a position of the subject in an imaging screen of the imaging sensor 3. A drop of a peripheral light volume due to an optical characteristic of the light emission lens 23 can be compensated by adjusting the light volume of the photographing auxiliary light. |
