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 10):
A focusing control method comprising:\n an evaluation value calculation step of causing 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 calculating evaluation values for determining a focusing position of the focus lens based on captured image signals acquired through the imaging; a focusing position determination step of selecting a plurality of evaluation values among the evaluation values calculated in the evaluation value calculation step, calculating a maximum point of an evaluation value curve indicating a relationship between the evaluation values and the positions of the focus lens based on the plurality of selected evaluation values, and determining a position of the focus lens corresponding to the maximum point, as the focusing position; and a focusing control step of performing focusing control to move the focus lens to the focusing position, wherein, in the evaluation value calculation step, the evaluation values are calculated based on signals acquired by performing any filtering process selected among a plurality of filtering processes in which passbands are different on the captured image signals, and the focusing position determination step makes, in the selecting of the plurality of evaluation values among the evaluation values calculated by the evaluation value calculation step, number of the selected evaluation values in a case where a lower frequency limit of a passband of the filtering process selected by the evaluation value calculation step is equal to or lower than a frequency threshold value to be greater than number of the selected evaluation values in a case where a lower frequency limit of a passband of the filtering process selected by the evaluation value calculation step is higher than the frequency threshold value.
