Abstract
A focus control device includes a processor. The processor analyzes detection results of a target object in time sequence to determine whether the target object is in a lost state in which the target object is not temporarily captured into an image, sets a focus drive mode to an autofocus mode when the target object is detected, sets a first positional mode in which the focus lens is arranged at a position that is within a set range of an in-focus object plane position and is on the far point side of a central position when the target object is not detected and is not in the lost state, and sets the focus drive mode such that a lens position is nearer to a near point than in the first positional mode or sets the focus drive mode to the autofocus mode in a when the lost state is determined.
