  • Patent number: 8692908
    Abstract: An image-pickup apparatus includes an image-pickup element that photoelectrically converts an optical image formed by an image-pickup optical system having a zoom function, and a correcting part that performs correction processing for a distortion component in image data generated based on an output from the image-pickup element, the distortion component corresponding to a distortion of the image-pickup optical system. The image-pickup optical system provides a first zoom range in which a distortion amount at a certain image height is larger than a predetermined value and a second zoom range in which a distortion amount at the certain image height is smaller than the predetermined value. The correcting part performs the correction processing so that the distortion component remains in a first corrected image data in the first zoom range is larger than the distortion component remaining in a second corrected image data in the second zoom range.

  • Patent number: 8605200
    Abstract: An optical apparatus includes a calculator that calculates a position of a focus lens for focusing on a subject, a setter that sets a permissible movable range of the focus lens, and a controller that sets, when the position of the focus lens calculated by the calculator is within the permissible movable range, the position to a target position to which the focus lens is moved. The setter redefines the permissible movable range based on position information showing one of the target position and a position of the focus lens after a movement of the focus lens toward the target position. The optical apparatus suppresses a focusing operation for a subject for which an operator does not intend to perform focusing.
