Abstract
Abstract An electronic engraving system is provided wherein an object, e.g., a person, for a picture to be engraved on a card is picked up by a television camera and converted into corresponding electric signals; the electric signals are stored first and then read out at a lower scanning speed that suits a mechanical scanning system through scanning conversion means, and the picture of the object is engraved on the material in accordance with the read out signals, whereby the picture corresponding to the object can be easily engraved on the material, e.g., a plastic card without using any photographic original picture of the object.
