  • Patent number: 9596400
    Abstract: An image pickup apparatus capable of performing proper image evaluation in photographing a moving image by changing the exposure condition. An image pickup unit picks up an image of an object and a driving unit drives a focus lens in an optical axis direction. A control circuit controls a focus state of the object by causing the driving unit to move the focus lens in the optical axis direction. A focus evaluation value is acquired from each image. The control circuit causes the image pickup unit to pick up images of a multistage exposure image group by changing exposure time, selects an image according to exposure time, updates a direction of driving the focus lens using the focus evaluation value acquired from the selected image, and causes the driving unit to move the focus lens in the updated driving direction.

  • Patent number: 8964043
    Abstract: When correcting rotary shake, an area to be referenced when distortion aberration correction is performed is rotated by a detected rotation amount in a direction correcting the rotary shake, such that the reference area fits into the area of an image that has been captured. A rectangular image of the same size as the captured image is obtained by applying distortion aberration correction to an image included in the reference area. If the reference area will not fit into the area of the captured image when rotated by the detected rotation amount, the reference area is rotated by a maximum angle at which the reference area will fit into the area of the captured image, and distortion aberration correction is applied to the image included in the reference area. Information on the captured angle of view can thereby be effectively used when performing distortion aberration correction and rotary shake correction.

  • Patent number: 8705813
    Abstract: An identification device capable of improving identification accuracy. The identification device performs identification according to a face area contained in image data. Feature data is extracted from a face area in each of frames of image data. The extracted feature data is registered in a person database section. Identification is performed through comparison between the feature data registered in the person database section and the extracted feature data. A tracking section identifies an identical face area in consecutive frames. If a face area is identified in a first frame, but a face area in a second frame following the first frame, which is identified by the tracking section as identical to the identified face area in the first frame, is not identified, the extracted feature data associated with the face area in the second frame is registered as additional feature data in the person database section.
