    Abstract: An image pickup apparatus that can efficiently obtain an offset between focal positions detected in phase difference-based focus detection and contrast-based focus detection by using results of phase difference-based focus detection at multiple points. Focal positions in a plurality of regions based on a pair of image signals obtained from different pupils are obtained. A focal position for a focus lens at which a contrast of image signals for image pickup is at a peak is detected. A target focal position is determined from the plurality of focal positions. When another focal position is present between a present focal position and the target focal position, an offset between a focal position of the focus lens at which the contrast detected at the other focal position while the focus lens is moving is at a peak and the other focal position is calculated.

  • Patent number: 8538252
    Abstract: A face detecting section of a camera detects a face area in a shooting screen under an output of an image sensor. A focus detecting section calculates a defocus amount from a relative interval of a pair of images under an optical flux passed through a shooting lens in each of optional areas in the shooting screen. A first focus controlling section specifies a focus detecting area from the optional areas under an output of the face detecting section, and performs a focus operation under the defocus amount of the focus detecting area. A second focus controlling section calculates a focus evaluation value in the face area under an output of the image sensor, and performs a focus operation by using the focus evaluation value. A control section causes at least one of the first focus controlling section and the second focus controlling section to perform a focus operation.

  • Patent number: 8494357
    Abstract: A system, computer readable medium, and method for dynamically setting a camera's exposure parameters based on face detection are disclosed. When taking a picture or video of a person in front of a bright background, standard exposure algorithms tend to overexpose the background. In one embodiment disclosed herein, a face detection algorithm is run on the current picture or video frame, and the exposure metering region is inset over the detected face. Exposure time, gain, or other exposure parameters may be set based on the pixels within the exposure metering region. In another embodiment, the exposure metering region tracks a moving face according to lag parameters so that the exposure metering region remains substantially over the face. In yet another embodiment, a plurality of faces may be tracked, with the exposure parameters set based on a weighted average of the pixels within the plurality of face-containing exposure metering regions.

  • Patent number: 8488958
    Abstract: Systems, methods, and a computer readable medium for an improved automatic exposure algorithm attempt to classify an image into a particular “scene category,” and, based on the determined scene category, meter the scene according to a generated metering weighting matrix. In one embodiment, the average luminance is calculated for a central exposure metering region of the image and a plurality of peripheral exposure metering regions surrounding the central exposure metering region. Based on comparisons of the average luminance values of the peripheral exposure regions to the average luminance of the central exposure region, a target metering weighting matrix may be generated. In another embodiment, the scene category corresponds to a predetermined metering weighting matrix.

  • Patent number: 8472798
    Abstract: A camera and a method for selecting a focus region in a camera view have a plurality of focus regions that are defined in the camera view. A focus distance of the camera is repeatedly set to focus at different distances by setting a lens distance of the camera to different lens distance values. A focus value is determined for each focus region at the set lens distance value. A function for a plurality of focus regions is estimated based on a plurality of determined focus value and lens distance value pairs. A local maximum point of the function is calculated for each focus region for which a function has been estimated, where the local maximum point has a lens distance value. Focus regions are grouped, rated and selected based on the lens distance value of the local maximum point of the focus regions and spatial distances between the focus regions.
