  • Publication number: 20110305446
    Abstract: An imaging apparatus includes: a focus lens; an imaging device; a movement detecting unit that detects the movement of an image on the basis of a difference between a plurality of image data which is output from the imaging device in time series; an estimating unit that estimates the movement of an object or a photographer on the basis of the movement of the image detected by the movement detecting unit; a movement range setting unit that sets a movement range of the focus lens on the basis of the movement of the object or the photographer estimated by the estimating unit; and a focus position detecting unit that moves the focus lens in an optical axis direction in the movement range set by the movement range setting unit and detects a focus position where the focus lens is focused on the position of the object of the image.

  • Patent number: 7916182
    Abstract: An apparatus and method for capturing images using a delay timer and face detection. After a command is given to begin a photographing process, a face detector determines the location of a face of a person being photographed. A timer counts down a predetermined delay time, for example, corresponding to a self-timer time period. A controller can set the auto focus or auto exposure parameters based on the detected face.

  • Patent number: 7283736
    Abstract: An imaging apparatus including a ranging device for measuring a distance to a subject, a device for radiating fill-light to the subject, and a re-ranging determining device for determining as to whether re-measurement is executed based on a measured result of the ranging device, when the re-ranging determining device determines that the re-measurement by the ranging device is required, the fill-light radiating device radiating the fill light to the subject based on the determination of the re-ranging determining device, the ranging device having a ranging element mechanism for allowing a light flux from the subject to image thereon to measure the distance to the subject, a ranging arithmetical mechanism for achieving an arithmetic of the ranging based on outputting data of the ranging element mechanism, and an area selecting mechanism for selecting an area based on an arithmetical result of the ranging arithmetical mechanism.
