摘要:
An optical unit is provided which is characterized by compact configuration, high performance and minimized noise, and which has a drive element to drive a lens cone holding an image pickup optical system, and has the same outside diameter as the lens cone, wherein the optical unit drives the image pickup optical system by expanding and contracting the drive element in a direction of an optical axis of the image pickup optical system. An image pickup apparatus is provided which is characterized by compact configuration, high performance and minimized noise, and which has an optical unit coupled to an image pickup unit through a drive element, and has the same outside diameter as the optical unit, wherein the apparatus drives the optical unit by expanding and contracting the drive unit in a direction of an optical axis of the optical unit.
