Title:
IMAGING DEVICE, FOCUSING ASSISTANCE METHOD THEREFOR, AND FOCUSING ASSISTANCE PROGRAM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/167482
Kind Code:
A1
Abstract:
Provided are an imaging device which can assist focusing without giving a sense of incongruity, a focusing assistance method therefor, and a focusing assistance program therefor. On the occasion of moving an image sensor to assist manual focusing, the speed of focus adjustment by an imaging lens is detected. If the speed of the focus adjustment by the imaging lens has lowered to a threshold value or below, assistance is started by moving the image sensor. At such time, the movement of the image sensor is controlled so that the sum of the speed of the focus adjustment by the imaging lens and the speed of the focus adjustment by the movement of the image sensor is a threshold value or less, thereby leading to an in-focus state.
