A horizontal scanning rate correction apparatus for a cathode-ray tube, particularly of the beam index color cathode-ray tube, particularly of the beam index color cathode-ray tube type includes a memory for storing correction values, representing deviations of the horizontal scanning rate of the electron beam, from a desired scanning rate at each of a plurality of horizontal sampling positions along each of a plurality of predetermined horizontal sampling lines, which are substantially fewer in number than the horizontal lines along which scanning occurs.
