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.
Claims7
An electronic engraving system comprising:
- an image pickup means for generating electric signals corresponding to an object;
- a signal storage and readout means of the scanning conversion type for storing said electric signals from said image pickup means at a high speed and reading out said stored electric signals at a low speed corresponding to an engraving speed in accordance with command signals;
- an engraving means for engraving a picture of the object on a material in response to said read out electric signals, said engraving means including an engraving head having an engraving style arranged to face an engraving table, means for reciprocating said engraving table or engraving style and means for shifting said engraving style transversely to the direction of the reciprocation of said engraving table or engraving style;
- and
- a command signal producing means for producing said command signals, said command signal producing means including a pulse producing means for producing pulses in response to the reciprocation of said engraving table or engraving style and a synchronizing pulse generating circuit for generating a synchronizing pulse in response to said pulses produced by said pulse producing means.
