Abstract: A video monitoring system for a movie film camera usable with either spherical or anamorphic lenses wherein conventional, unmodified video monitors and recorders may be used. A video camera is positioned in the film camera to receive an image directly from the camera lens without interposing either a ground glass for imaging or an optical deanamorphosing lens. The anamorphic image, which is horizontally squeezed (such as by a factor of 2), that is received by the video camera then is electronically processed to deanamorphose the image by producing an analog video signal to a video monitor that displays the properly proportioned image in the middle one-half of the monitor screen and produces black areas or strips across the top one quarter and bottom one quarter of the screen. The horizontal lines of the video picture are electronically interpolated for enhancing the picture.

The lamp can be wired to utilize the internal power supply of the projector by means of specifically designed electrical connectors.

Abstract: A method and apparatus for decoding and receiving a sequence of image frames employ selectively a measure of motion displacement for generating a motion compensated image and filter selection data. The motion compensated image, together with an error signal, provides the receiver with full detail regarding the next frame of a sequence. In some instances, however, the motion displacement data is inaccurate for portions of the next image frame. In those instances, the method and apparatus determine from the filter selection data that filtering of a portion of a previously received image provides a lower error energy for the resulting prediction of the image. If a lower error energy is not achieved by low-pass filtering, the data from the communications path regarding the motion displacement enables the receiver to reconstruct at least a block portion of the image frame.
