Title:
FOCUS CONTROL DEVICE, FOCUS CONTROL METHOD, PROGRAM, AND IMAGE CAPTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/096810
Kind Code:
A1
Abstract:
For example, in cases where a defocus amount in a distance measurement area is greater than a drive control determination threshold set in advance, a focus drive control unit 34 of a control unit 30 performs speed-prioritizing drive control that drives a focus lens to an in-focus position in accordance with a drive pattern selected by a user in advance. In cases where the defocus amount in the distance measurement area is less than or equal to the drive control determination threshold, the focus drive control unit 34 performs subject-prioritizing drive control that drives the focus lens by setting a focus lens movement amount that moves the focus lens to the in-focus position in accordance with the defocus amount. The focus lens can be driven to the in-focus position in accordance with a drive pattern selected by the user, and then the in-focus state can be maintained. Thus, it is easy to perform an autofocus operation having a high degree of freedom.
