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 21):
The focusing control method according to  claim 15 , further comprising:\n a target position prediction step of predicting the target position of the focus lens based on a target position history of the focus lens determined in the target position determination step; and a phase difference amount prediction step of converting a difference between the target position predicted in the target position prediction step and a position of the focus lens into a phase difference amount, and predicting the phase difference amount, wherein, in the target position determination step, a phase difference amount closest to the phase difference amount predicted in the phase difference amount prediction step is extracted from the first phase difference amount and the plurality of second phase difference amounts in a case where the reliability exceeds the threshold value, a temporary target position of the focus lens is calculated based on the extracted phase difference amount, 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 is determined, the first process is performed in a case where the target position of the focus lens based on the first phase difference amount falls within the depth range, and the second process is performed 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.
