ABSTRACT:
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.
