Provided is a focus lens control apparatus, including: an evaluation signal acquisition unit for acquiring an evaluation signal indicating an in-focus condition from a high frequency component of an acquired image by causing an actuator to drive a focus lens; a detection unit for detecting a driving condition of the actuator; and a drive control unit for performing driving of the focus lens based on the evaluation signal and, after calculating an in-focus position from the evaluation signal, performing the driving of the focus lens under closed-loop control based on an output from the detection unit.
