A video assist system operates in parallel with a motion-picture camera by recording and scanning periodic frames of the motion-picture image. Each recorded frame is transferred to intermediate storage where data from that frame may be processed at a rate which is independent of the motion-picture capture rate. Data for each recorded frame is translated into an intermediate signal format in which each line of a television ('TV') image signal is transmitted at a standard TV signal rate, but in which an entire frame is transmitted at the motion-picture capture rate. The intermediate signal format is presented to a frame buffer which allows conversion to a standard TV signal format.

Video assist system for motion-picture camera

In a video camera, 'shading ears' resulting from charge build-up beyond the ends of the scan lines of the normally scanned area of a camera tube target are eliminated by applying a voltage pulse to a lens electrode of the camera tube, the timing, amplitude, duration, and shape of the pulse being predetermined to extend the scan lines, and also to de-focus the electron beam.
