When sweeping lines in a first field of interlaced fields on a television camera photosensitive storage layer adjacent portions of lines in a second field also are swept. Smearing effect or image carryover is reduced by reducing migration or leakage of charge between unswept lines of the second field and swept lines of the first field. Preferably horizontal lines are narrowed by anamorphically projecting images on the coating, thus shrinking images vertically, while maintaining their horizontal dimensions. Alternatively beams may be oscillated vertically while sweeping horizontally, or vertical cross sectional dimensions of beams may be increased.
