Abstract
An image pickup device includes an optical system, an image pickup unit that captures a subject image through the optical system and generates a captured image, and a controller that calculates an evaluation value from a region corresponding to an AF frame in the captured image and drives the optical system according to the calculated evaluation value to perform an automatic focus operation. The controller includes a normal illumination mode set when brightness of the captured image is a predetermined value or more, and a first low-illumination mode and a second low-illumination mode set when the brightness of the captured image is less than the predetermined value. In the first low-illumination mode, a first automatic focus (AF) frame that is larger than an AF frame set in the normal illumination mode is set. In the second low-illumination mode, a second AF frame that is smaller than the first AF frame is set.
