Abstract
A calibration method for an imaging device including a camera module including an imaging element and a lens installed on a path of light incident on the imaging element; a blur detection element configured to detect an amount of blur acting on the imaging device; and a gravity detection element configured to determine a direction of gravity acting on the imaging device. The calibration method includes: detecting a first angle corresponding to a deviation of a direction of a coordinate axis of the blur detection element with respect to the direction of gravity; detecting a second angle corresponding to a deviation of a direction of the camera module with respect to the direction of gravity; and acquiring a parameter for correcting a detection signal of the blur detection element based on the first angle and the second angle.
