Abstract: An image processing apparatus includes an image pickup circuit having a plurality of photographic modes, such as television standards, a compression processing circuit for performing compression processing of an image pickup signal outputted from the image pickup circuit, the compression circuit having a plurality of compression modes, and a selecting circuit for selecting one of the compression modes of the compression processing circuit in accordance with a selected one of the photographic modes of the image pickup circuit.

Abstract: In an apparatus adapted to a photographic film having a magnetic recording part, a magnetic recording device continuously records magnetic information on an area of the photographic film extending from a leader part thereof to inside an image recording area thereof.

Abstract: A lens barrel includes fixed tubes each arranged to hold an optical unit having an optical axis, a rotating tube arranged to rotate around the optical axis with respect to the fixed tubes, wherein the rotating tube is provided, at front and rear portions thereof as viewed along the optical axis, respectively with end surfaces of ring shape having a center thereof on the optical axis, and each of the fixed tubes is provided with an end surface opposite to the associated end surface of the rotating tube, and sheet members of ring shape having a center thereof on the optical axis, each of the sheet members being disposed on a space formed by each end surface of the rotating tube and the associated end surface of the fixed tubes, so that the torque of a rotating operation on the rotating tube is lessened and, yet, the lens barrel excels in dust-proof and drip-proof.
