Title: CONTROL DEVICE, CONTROL METHOD, COMPUTER PROGRAM AND ELECTRONIC APPARATUS
Abstract:
[Problem] To provide a control device that effectively determines a lens position even if a subject which is close to an image pickup device and a subject which is far therefrom are simultaneously present in a region for detecting the phase difference of a subject image. [Solution] Provided is a control device comprising the following: a calculation unit for calculating a focal position in each of multiple phase-difference detection regions, on the basis of the image pickup results of a subject image which passes through a focal lens, the image pickup results according to an image pickup element that contains the multiple phase-difference detection regions; and a determination unit for determining the position of the focal lens on the basis of the average value of the focal positions of the phase-difference detection regions calculated by the calculation unit, such average value being in a prescribed range from a focal position which is on the infinity side or the near side.
