  • Publication number: 20120212661
    Abstract: An imaging apparatus includes: a display unit that displays an image photographed by an imaging element; and a focus control unit that performs focus control of inputting information regarding a selected image region of the image displayed on the display unit and setting a subject contained in the selected image region as a focusing target. The focus control unit performs the focus control by determining a driving speed of a focus lens based on information regarding an operation of a user and moving the focus lens at the determined driving speed of the focus lens.

  • Patent number: 8106997
    Abstract: In an image pickup apparatus, a light receiving unit produces a first signal at a first timing and a second signal at a second timing later than the first timing. First and second parameters for detecting a scene change are acquired based on the first and second signals, respectively. The presence or the absence of a scene change is determined based on both the parameters. The apparatus further includes a selecting unit configured to select a focusing target AF area from among a plurality of AF areas, and a focusing control unit configured to execute focusing control by using focusing information with respect to the AF area selected by the selecting unit. When the determining unit determines that the scene change is not present, the selecting unit selects the AF area having been selected at the first timing, as the focusing target AF area, at the second timing continuously.

  • Patent number: 6456795
    Abstract: In a multifunction camera, an area selector is used both as an operation key in a first selection mode for selecting the focus detection area of the focus detection device, and as an operation key in a second selection mode for selecting the function setting of the camera. A mode selector is provided which is settable at three positions including a local position, wide position, and lock position. The focus detection area selected at the local position is locked when the mode selector is set at the lock position and has been moved from the local position to the lock position, whereas the wide position is locked when the mode selector has been moved from the wide position to the lock position.

  • Patent number: 5825016
    Abstract: Where a person is being photographed, for example, both light from the person located at closer range and light from the background located farther away enter the photodetector elements. Where the contrast of the background is high, the rate at which the information from the background contributes to the focus detection becomes larger, which hinders accurate focus detection with regard to the person. In this case, the focus detection device divides a predetermined focus area into smaller areas and detects focus condition in each smaller area.
