Abstract: An image stabilization apparatus includes a fixed barrel, a movable barrel, a support member configured to movably support the movable barrel with respect to the fixed barrel, a drive unit configured to include a magnet and a coil, and drive the movable barrel, a control section configured to drive and control the drive unit, a position detection section configured to detect a position of the movable barrel, and a judgment section configured to detect, when the drive unit drives via the movable barrel so as to move to a predetermined target position, a deviation between the position of the movable barrel and the predetermined target position and judge whether or not the apparatus operates normally based on whether or not the deviation falls within a first allowable range.

Abstract: An image stabilization apparatus includes a fixed barrel member, a movable barrel member configured to hold an optical lens, a support member configured to movably support the movable barrel member with respect to the fixed barrel member within a plane orthogonal to an optical axis of the optical lens and a drive unit configured to drive the movable barrel member with respect to the fixed barrel member, in which the fixed barrel member or the movable barrel member includes a support member disposing portion configured to rotatably accommodate the support member and limit an amount of movement of the support member within a plane and a small spatial region portion formed by notching part of the support member disposing portion so as to communicate with the support member disposing portion, an interior of the small spatial region portion being filled with a lubrication member.

Abstract: A shake correction apparatus includes: a stationary portion (21) having coils (22S, 22L, 23S, 23L, 24S, 24L) arranged; a movable portion including magnets (52a, 52b, 52c, 52d, 53a, 53b, 53c, 53d, 54a, 54b, 54c, 54d) opposed to the coils and an imaging element; a supporting member for movably supporting the movable portion to the stationary portion along a plane orthogonal to an optical axis of light entering into the imaging element; means for detecting a position of the movable portion; and means for controlling current flowed into the coils based on output of the detection means, the coils including at least three coil pairs when two coils opposed to each other along the plane orthogonal to the optical axis are paired, driving forces of two coils forming each coil pair being different.
