Abstract
An imaging device includes: a lens including a focus lens capable of moving in an optical axis direction; an imaging element imaging a subject through the focus lens; and a processor controlling the focus lens and the imaging element and selectively performing one of acceleration and deceleration control such that a movement speed of the focus lens is decelerated after the movement speed is accelerated and constant speed control such that the movement speed of the focus lens is constant by controlling the movement speed based on evaluation values, lens performance information, and first imaging performance information so as to move the target lens to a target position.
