Patent number: 7783186Abstract: An imaging apparatus includes a face detecting unit that detects a face area from an input image inputted in the imaging apparatus and a control unit that executes a focus operation according to adjustment of a focus lens. The control unit judges whether, during the focus operation, a new face has appeared in a position closer to the imaging apparatus than a position of a face closest to the imaging apparatus among faces detected before the start of the focus operation on the basis of the number and sizes of the faces detected and performs processing for re-executing or stopping the focus operation on the basis of a judgment result indicating that a new face has appeared in a position closer to the imaging apparatus.Type: GrantFiled: June 8, 2007Date of Patent: August 24, 2010Assignee: Sony CorporationInventors: Hisashi Ishiwata, Yoshito Terashima, Tetsuo Mise, Masakazu Koyanagi

Patent number: 7250974Abstract: An image pickup apparatus for electronically photographing a still image using a photo-voltaic transducer device. The focusing position of a focusing lens is detected from the contrast of the photographed image as AF supplementary light is illuminated on the object. The focusing lens then is moved to its focusing position and the contrast of the photographed image, in both the state where the AF supplementary light is illuminated and the contrast in the state where the AF supplementary light is not illuminated, is calculated. The contrast ratio between the contrast values of the two states is estimated and the focusing position is corrected based on this ratio.Type: GrantFiled: September 2, 2002Date of Patent: July 31, 2007Assignee: Sony CorporationInventor: Masakazu Koyanagi

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
