Title:
IMAGING DEVICE INCLUDING TREMOR CORRECTION UNIT
Document Type and Number:
Japanese Patent JP2020086190
Kind Code:
A
Abstract:
To reduce exposure unevenness in a lateral direction of a screen for each photographing.SOLUTION: An imaging device comprises: a tremor detection unit 14 that detects a tremor; an image pick-up element 6 that captures a subject image; a tremor correction unit 14 that moves the image pick-up element 6 in an in-plane perpendicular to an optical axis; a tremor control unit that prepares a tremor correction signal from the tremor detected by the tremor detection unit, and controls the tremor correction unit; an electronic front curtain 61 that performs a reset operation of an accumulated amount of charge of the image pick-up element; a shutter device 16 that switches shielding or passage of the subject image condensed to the image pick-up element 6; and a plurality of arm driving members (435 and 436) that perform a link drive of a rear curtain. In the shutter device 16 having an actuator 480 making a rotation axis of either one of the arm driving members eccentric, when performing exposure control by the electronic front curtain 61 and the rear curtain of the shutter device 16, the rotation axis 450a of the arm driving member is made eccentric according to a tilt of the image pick-up element controlled by the tremor correction unit to tilt the rear curtain, and driving is made possible so that the electronic front curtain and the rear curtain are almost parallel.SELECTED DRAWING: Figure 7
