Abstract:
1. An image blur compensation unit, comprising: a first and a second refractive element that are disposed along an optical axis of light that is guided to an imaging element after passing through an optical lens, and which rotate with respect to a central axis that goes along the optical axis to refract the light to correct a blur of an image that is guided to the imaging element; a first support portion that is provided in one region of 180 degrees or less out of two divided regions with respect to the central axis on a plane perpendicular to the central axis, and which supports the first refractive element on an outer periphery side; a second support portion that is provided in the other region of 180 degrees or less out of the two divided regions, and which supports the second refractive element on an outer periphery side; a base section that supports the first and second support portions at three or more points on a plane perpendicular to the central axis in such a way that the first and second support portions can rotate around the central axis; and a first and a second drive mechanism that are respectively placed in regions where the first and second support portions are provided, and which drive the first and second support portions in such a way that the first and second support portions rotate around the central axis only within the regions to rotate the first and second refractive elements, wherein the first and second drive mechanisms include the center of the first magnet is located inside a polygon connecting points where the first support portion is supported, and the center of the second magnet is located inside a polygon connecting points where the second support portion is supported.
