Title:
IMAGING DEVICE, SYSTEM, IMAGE BLURRING CORRECTION METHOD, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/044585
Kind Code:
A1
Abstract:
This imaging device comprises: an optical system which forms a subject image on an imaging element; an angular velocity sensor which detects angular velocities in a plurality of rotation directions; a first memory which holds, as a reference value, the angular velocities in the plurality of rotation directions detected by the angular velocity sensor when the imaging device is stationary with respect to the ground; a second memory which holds rotation angular velocities in a plurality of rotation directions that occur in the imaging device due to the rotation of the earth; a subtraction circuit which subtracts a reference value held in the first memory from the angular velocity detected by the angular velocity sensor, for each rotation direction in the plurality of rotation directions; a circuit which calculates an image blur correction amount to cancel the blurring of the subject image imaged on the image sensor, on the basis of the subtraction result of the subtraction circuit or the rotation angular velocities in the plurality of rotation directions held in the second memory, according to an operation mode of the imaging device; and a drive control circuit which drives a first drive mechanism for moving the image sensor or the first drive mechanism and a second drive mechanism for moving a part of the optical system, on the basis of an image blur correction amount.
