  • Image conversion process and apparatus
    Patent number: 5659382
    Abstract: A process for transferring images from a first frame system to a second frame system is described. A first sequence from the first frame system is determined so as to include a plurality of image frames, wherein each image frame includes a central timing factor. Likewise, a second sequence from the second frame system is selected so as to include a plurality of image frames, wherein each image frame includes a central timing factor. Each image frame for the newly constructed second frame system is built by combining at least two image frames from the first frame system in a proportion such that the central timing factors of the two image frames of the first frame system combine so as to correspond to the central timing factor for the image frame in the second frame system. In this manner, the images from the first frame system combine in a smooth fashion in the second frame system such that jitter, freezes and jumps are eliminated.

  • Optical imaging system and graphic user interface
    Patent number: 6327097
    Abstract: The invention relates to an optical imaging system for imaging an object with progressively adjustable magnification. The inventive system comprises an imaging plane for projecting an image field originating from the object and an imaging optical system situated on the object side in front of the imaging plane, preferably with a fixed focal length for producing the image field on the imaging plane. Said imaging optical system and/or said imaging plane are arranged so that they can move in the direction of the optical axis in order to adjust the magnification and/or focus the image appearing on the imaging plane.

  • Device and process for producing a composite picture
    Patent number: 6348953
    Abstract: Apparatus for producing a composite image from a foreground image (FG), showing an object or a scene with a substantially monochrome background, and background image (BG) comprising a first processing unit (R4) for producing a control signal (SEP) for each pixel of the foregoing image (FG), reflecting whether an individual pixel of the foreground image is part of the object or part of the monochrome background, based both on the chromatic values of the pixel and on predetermined chromatic values, describing the color composition of the monochrome background, a selection unit (R5) suffixed to the first processing unit (R4), for calculating the chromatic values of an individual pixel of the composite image from, depending on the control signal (SEP), either the chromatic values of the corresponding pixel of the foreground image (FG) or the chromatic values of the corresponding pixel of the background image (BG), a second processing unit for calculating correction values for the chromatic values of an individual
