Abstract:
A focus control device includes a processor including hardware, the processor being configured to implement: an area setting process that sets a plurality of areas, each including a plurality of pixels, on a captured image acquired by an imaging section, an evaluation value calculation process that calculates an AF (Autofocus) evaluation value for each of the plurality of set areas, a bright spot influence rate calculation process that calculates a bright spot influence rate for each of the plurality of set areas, based on whether or not the area includes a high luminance portion determined to have a size equal to or larger than a given size, and focus control based on the AF evaluation value and the bright spot influence rate.
