  • Patent number: 8676049
    Abstract: An imaging control unit includes: a detecting unit that detects a focused-status of a focus detecting range set to an image data of each frame; a setting unit that sets, at a position of a distinctive-region including a distinctive points of an object detected from an processed image data, a focus detecting range of an image data of a subsequent frame; and a control unit that performs, when the focus detecting range is not in focused-status, a focal length control to change a focal length of a imaging lens so that the focus detecting range is in focused-status. When a displacement amount from the focus detecting range set to the imaged image data to the distinctive-region detected in the processed image data based on the imaged image data is large, the control unit aborts performing the focal length control even when the focus detecting range is not in focused-status.

  • Patent number: 7847854
    Abstract: A novel imaging apparatus capable of correcting a focus state by an AF detection value both simply and surely has been disclosed. The imaging apparatus comprises an auto-focus drive section for moving a lens, an AF processing section for calculating an AF detection value indicating the focus state from imaging data, a luminance processing section for calculating a luminance value from the imaging data, a correction section for calculating a corrected AF detection value by correcting the calculated AF detection value by the calculated luminance value, and a control section for controlling the auto-focus drive section based on the calculated corrected AF detection value. The imaging data is data not having been subjected to auto-exposure processing.
