Abstract
An imaging device includes: imaging lens displaceable in first and second directions in plane perpendicular to optical axis; actuator positioning the imaging lens in the first and second directions; position detector generating first and second position detection signals Hand H, Hincluding crosstalk component caused by displacing the imaging lens in the second direction, and Hincluding crosstalk component caused by displacing the imaging lens in the first direction; crosstalk compensator correcting Hand Hto reduce crosstalk components included in Hand H; and driver controlling the actuator based on corrected first and second position detection signals H' and H′, wherein when ratio of Hto Hwhile driving the imaging lens in the first direction is α and ratio of Hto Hwhile driving the imaging lens in the second direction is β, the crosstalk compensator reduces crosstalk components included in Hand H.
