PROBLEM TO BE SOLVED: To provide a three-dimensional imaging apparatus, to which contrast AF is adapted to obviate defects of phase-difference AF and in which processing time of contrast AF is shortened, and focusing accuracy is improved.SOLUTION: A phase-difference CCD, in which object images having passed through different regions in a predetermined direction of a single photographing optical system are pupil-split and respective imaged, subjects the object images having passed through the respective regions to photoelectric conversion to obtain a main image and a sub image which have a mutual phase difference. Contrast AF is performed using only one of the main image and the sub image. Here, which one of the main image and the sub image is used for the contrast AF is determined depending on whether the position of an AF area in the angle of view belongs to a main pixel AF area or a sub-pixel AF area. |
