Patent number: 7224396Abstract: The present invention concerns a digital still camera (1). This camera carries out a framing process by using an infrared pick-up image and a visible light photographing by using a flash or a low speed shutter in a still image pick-up process. Upon automatic focusing, the light of an auxiliary visible light source (23) for automatic focusing is emitted to apply the visible lights and carry out an automatic focusing process. In the digital still camera, the framing process can be carried out which allows the image of a subject which is to be picked up to be displayed on a finder even under an environment of low illuminance such as photographing a dark place and a user to recognize the contents of the photographed image. Further, after that, even when the visible light photographing is carried out through the irradiation of flash or the low speed shutter, an accurate focusing can be realized.Type: GrantFiled: August 14, 2002Date of Patent: May 29, 2007Assignee: Sony CorporationInventors: Yoshikazu Oochi, Masakazu Koyanagi, Kenichi Sanpei, Takahiro Koyama, Toshinori Orito
