DRIVING DEVICE AND DRIVING METHOD
Document Type and Number:
Japanese Patent JP2023106293
Kind Code:
A
Abstract:
To correct a tilt of a lens due to unbalance in drive capability among a plurality of drive sources according to a position of the lens.SOLUTION: A driving device is provided, which comprises: a calculation unit that calculates a driving amount of an optical element based on a detected position of the optical element and a target position of the optical element; a correction unit into which the driving amount, the detected position, and the target position are input, and which generates a corrected driving amount by correcting the driving amount based on the driving amount, a parameter corresponding to the tilt of the optical element, and one of the detection position and the target position, and outputs the driving amount and the corrected driving amount; a first driving unit that applies a first driving force corresponding to either one of the driving amount and the corrected driving amount to a first driving source among a plurality of driving sources for moving the optical element in a predetermined direction; and a second driving unit that applies a second driving force corresponding to the other of the driving amount and the corrected driving amount to a second driving source of the plurality of driving sources.SELECTED DRAWING: Figure 1
