  • Flange-back adjusting method and apparatus for a video camera using an inner focus lens assembly
    Patent number: 5764290
    Abstract: Flange-back adjustment in a video camera using an inner focus lens assembly is done by detecting a position on the top of an actual zoom tracking curve and by detecting positions of end points of a variater on the basis of the top. Positions of the end points are presumed by a calculation from a position of the variater before arrival at an end. That is, by using the position of the variater in focus as a result of a movement of a focus lens from the top, and a ratio of a distance from the position of the variater in focus to one of the end points versus a distance from the position of the variater in focus to the other of the end points, positions of the end points are obtained.
