PROBLEM TO BE SOLVED: To provide a camera capable of improving the S/N of a range-finding signal and realizing accurate focusing at a high speed with a simple constitution. SOLUTION: This camera system is provided with an infrared light emitting diode (3a) making a visible light component and an infrared light component out of light passing through a photographic lens incident on different positions on an image sensor, and decides the focusing point of the photographic lens on a subject according to an optical signal complying with the incident position of the infrared light component. |
