PROBLEM TO BE SOLVED: To provide a passive type auto-focusing device having plural charge storage type sensors and capable of realizing accurate focusing by obtaining an appropriate integration signal in all the photographic scenes including portrait photographing with a night scene as a background and a back light scene. SOLUTION: In the auto-focusing device, subject light is received by plural light receiving means equipped with plural photodetectors and defocus amount or a distance to a subject is measured based on output from plural light receiving means. In the device, the plural light receiving means generate monitor output showing respective integration amounts and subject circumstances are discriminated based on the mutual relation of the monitor output from the plural light receiving means, whereby the integration control parameter of the plural light receiving means is changed. |
