PROBLEM TO BE SOLVED: To provide a digital camera system for intra-oral photography which exactly controls the quantity of the light emitted by a ring flash by a photometric sensor exactly receiving the reflected light from a subject and makes it possible to obtain bright images. SOLUTION: This digital camera system has lens barrels 12 and 13 having an optical system including an objective lens 14, a finder, a liquid crystal display section for monitor, a release button 19 and a controller 22 having a power source. The lens barrels are provided with the ring flash 15 so as to enclose the objective lens and the lower part at the front ends of the lens barrels is provided with the photometric sensor 26. A photodetecting surface 28 of the photometric sensor is inclined to a surface perpendicular to the optical axis of the optical system described above. |
