摘要： Pan-scan is provided for a standard 4:3 aspect ratio TV displaying a 16:9 aspect ratio high definition (HD) video stream using the motion vectors that are part of MPEG-encoded streams. Specifically, if, for instance, the MPEG motion vectors indicate an object rapidly moving to the left, the left-most part of the HD video frames are shown, instead of remaining centered on the HD video frames and cutting off the left and right portions.

The imaging lens includes a lens frame for supporting a lens serving as an adjusting lens and a support frame for supporting the lens frame. A contact section for support frame adjustment operable to come into contact with the lens frame is arranged in the support frame. A contact section for lens frame adjustment operable to come into contact with the support frame is arranged in the lens frame. The lens frame is configured such that the fastening force generated between the lens frame and the support frame can be applied vertical with respect to the contact section for support frame adjustment in a state of the contact section for lens frame adjustment held in contact with the contact section for support frame adjustment.

摘要： The present invention is directed to improve prior art zoom lens systems that have groups of lens pieces moved within a lens barrel for the zooming and the focusing and to provide an improved zoom lens system that is simplified and robust in configuration so as to withstand malfunctions well and is capable of effectively and assuredly eliminating stray light. The zoom lens system comprises a first cam barrel rotating about the optical axis and a second cam barrel located inside the first cam barrel in cam-linkage with the same, and the zoom lens system is characterized in that the second cam barrel has openings to let light beams pass through, and that a light-shielding plate like an iris diaphragm is supported by the second cam barrel in position closer to the photographed subject in the second cam barrel so as to shield the light beams that come in from the openings in the second cam barrel after going out of the openings in the second cam barrel and then being reflected from an inner surface of the first cam barrel.

摘要： A lens barrel having a cam barrel is disclosed. The cam barrel is molded by die-cutting in radial and other directions relative to the optical axis so as to have raised cams without undercuts if the raised cams are even partially lined up fore and behind one another along the optical axis, and there is no parting line in either the cam grooves nor the raised cams. The cam barrel has its outer surface provided with raised cams and is made of synthetic resin, and each of the raised cams has at least one of cam faces inclined toward an opposite cam face off a radial direction relative to an optical axis of the cam barrel.
