  • Patent number: 9826154
    Abstract: There is provided an imaging device including an imaging control unit that executes imaging control in first and second self-timer modes in which an automatic focusing process and an imaging process are executed in order after reception of an imaging start instruction. A first period from the reception of the imaging start instruction to execution of the automatic focusing process in the first self-timer mode is shorter than a second period from the reception of the imaging start instruction to execution of the automatic focusing process in the second self-timer mode.
    Type: Grant

  • Patent number: 9716831
    Abstract: An imaging apparatus including a mode sequence control unit configured to select a control scheme for a still image recording operation in accordance with an imaging operation setting, wherein the mode sequence control unit is configured to select a first control scheme when the imaging operation setting is a normal imaging setting and a second, different control scheme when the imaging operation setting is an unconscious imaging setting.

  • Patent number: 8031237
    Abstract: A technique of acquiring a width obtaining an appropriate exposure with minimum restrictions, while accurately correcting flickering is provided. An exposure control method includes integrating a video signal obtained by shooting a subject by means of a CMOS imaging element as input video signal over not less than a horizontal period, normalizing the integral value or the difference value of the integral value between neighboring fields or frames, extracting the integral value or the difference value after the normalization as flicker spectrum, determining, based on the extracted flicker spectrum, the presence or absence of a flicker component contained in the video signal obtained by the imaging element and controlling the exposure value, using a program diagram for preferentially employing the shutter speed less liable to produce flickering when it is determined that the video signal contains a flicker component.

  • Patent number: 7801437
    Abstract: An imaging device that controls strobe emission for red-eye prevention includes a face detector configured to detect whether a face region is included in an image captured by the imaging device; a luminance detector configured to detect a luminance representing a brightness of an imaging environment; and a red-eye preventing emission controller configured to control strobe emission for red-eye prevention on the basis of face detection information detected by the face detector and luminance information detected by the luminance detector.
