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.
