Abstract:
A focusing control device includes: a sensor as defined herein; a first correlation value generation unit as defined herein; a second correlation value generation unit as defined herein; a first phase difference amount measurement unit as defined herein; a second phase difference amount measurement unit as defined herein; a target position determination unit that selectively performs a first process of determining a target position of the focus lens based on the first phase difference amount and a second process of determining the target position of the focus lens based on the second phase difference amount, based on the correlation values acquired by the first correlation value generation unit and the correlation values acquired by the second correlation value generation unit; and a lens driving control unit that drives the focus lens to the target position determined through the first process or the second process.

Claim (Index 8):
The focusing control device according to  claim 2 , further comprising:\n a target position prediction unit that predicts the target position of the focus lens based on a target position history of the focus lens determined by the target position determination unit; and a phase difference amount prediction unit that converts a difference between the target position predicted by the target position prediction unit and a position of the focus lens into a phase difference amount to predict the phase difference amount, wherein the target position determination unit extracts a phase difference amount closest to the phase difference amount predicted by the phase difference amount prediction unit from the first phase difference amount and the plurality of second phase difference amounts in a case where the reliability exceeds the threshold value, calculates a temporary target position of the focus lens based on the extracted phase difference amount, determines whether or not the target position of the focus lens based on the first phase difference amount falls within a predetermined depth range using the temporary target position in a movement direction of the focus lens as a reference, performs the first process in a case where the target position of the focus lens based on the first phase difference amount falls within the depth range, and performs the second process in a case where the target position of the focus lens based on the first phase difference amount is out of the depth range, and in the second process, the target position of the focus lens is determined based on an average value of the second phase difference amounts measured for the divided areas in which the target position of the focus lens based on the second phase difference amounts falls within the depth range.
