Abstract:
A focusing control device includes: an evaluation value calculation unit that causes an imaging element which images a subject through a focus lens to image the subject for each of positions of the focus lens while moving the focus lens movable in an optical axis direction, and calculates evaluation values for determining a focusing position of the focus lens based on signals acquired by performing any filtering process selected among a plurality of filtering processes in which passbands are different on captured image signals acquired through the imaging; a focusing position determination unit as defined herein; and a focusing control unit that performs focusing control to move the focus lens to the focusing position, and the focusing position determination unit increases number of the selected evaluation values as a lower frequency limit of the passband becomes lower, as the filtering process selected by the evaluation value calculation unit.

Claim (Index 4):
The focusing control device according to  claim 3 ,\n wherein the focusing position determination unit selects a first evaluation value as a maximum value, second evaluation values acquired at positions from a reference position to an n-th position in which n is a natural number of 2 or greater on one side in a movement direction of the focus lens by using the reference position as a position of the focus lens at which the first evaluation value is acquired, and third evaluation values acquired at positions from the reference position to an n-th position on other side of the reference position in the movement direction of the focus lens, among the evaluation values calculated by the evaluation value calculation unit, and determines symmetry between curve portions constituted by two evaluation values acquired at positions separated from the reference position by two or more positions on the one side and the other side among the selected evaluation values and evaluation values acquired at adjacent positions, closer to the reference position than the separated positions, to the separated positions among the selected evaluation values, and excludes the two evaluation values and evaluation values acquired at positions farther from the reference position than the positions of the focus lens in which the two evaluation values among the selected evaluation values are acquired from the evaluation values used in the calculation of the maximum point in a case where the symmetry is lower than a symmetry threshold value.
