Abstract
For improving the sharpness of images produced on the screen of a cathode ray tube in a television receiver or other video signal reproducing device, a control signal is produced to vary in response to transient changes in the level of a video signal by which each electron beam in the cathode ray tube is density-modulated, and such control signal is supplied to a beam focusing electrode of the cathode ray tube so as to control the shape of a beam landing spot on the screen and thereby to prevent the image on the screen from becoming vague at its contours.
