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 1):
A focusing control device comprising:\n a sensor that has a focus detection area in which a plurality of first signal detection sections which receives one of a pair of luminous fluxes passing through different portions arranged in one direction of a pupil region of an imaging optical system including a focus lens and detects signals corresponding to light reception amounts and a plurality of second signal detection sections which receives other one of the pair of luminous fluxes and detects signals corresponding to light reception amounts are formed; a first correlation value generation unit that acquires correlation values between a first signal group output from the plurality of first signal detection sections of the focus detection area and a second signal group output from the plurality of second signal detection sections of the focus detection area; a second correlation value generation unit that performs a process of acquiring correlation values between a third signal group output from the plurality of first signal detection sections included in each of divided areas in a state in which the focus detection area is divided in the one direction and a fourth signal group output from the plurality of second signal detection sections included in the divided area, for each of the divided areas; a first phase difference amount measurement unit that measures a first phase difference amount between the first signal group and the second signal group from the correlation values acquired by the first correlation value generation unit; a second phase difference amount measurement unit that measures a second phase difference amount between the third signal group and the fourth signal group for each of the divided areas from the correlation values acquired by the second correlation value generation unit; 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.
