Abstract
The focusing control device capable of preventing deterioration in precision of focusing control from being caused by an error in phase-difference depending on ambient temperature includes: an imaging element that outputs a pair of image signals deviated in one direction on the basis of one subject light image; a phase-difference detection section that detects a phase-difference between the pair of image signals; a temperature detection section; a correction section that corrects the in-focus position of the focus lens based on the detection phase-difference, which is the phase-difference detected by the phase-difference detection section, on the basis of the data in which the temperature, the focus lens position, and the information for in-focus position correction are associated with one another, the temperature which is detected by the temperature detection section, and the focus lens position; and a lens control section that moves the focus lens to the corrected in-focus position.
