DRIVING APPARATUS, AND LENS APPARATUS AND IMAGE PICKUP APPARATUS INCLUDING THE SAME |
| 摘要 |
Provided is a driving apparatus for driving a movable optical member, the driving apparatus being removably attached to a lens barrel, the driving apparatus including: a rotary absolute position detector detecting a position of which the movable optical member, the rotary absolute position detector outputting an output value having a unique value with respect to a rotation angle within a range of a single rotation, and the output value having a point of discontinuity at which the output value is discontinuous every single rotation; and a controller performing boundary processing that handles the output value, corresponding to a driving range of the movable optical member, of the rotary absolute position detector having the point of discontinuity as a continuous value. |
