Video identification card system
摘要:
A video identification system for producing photo print identification cards having subject portrait, subject signature and subject related data in respective areas of the card as well as a data record including individual-specific data, an image of the subject, and an image of the signature of the subject. A personal computer controls the system to produce the identification card and the data record. The system includes a frame grabber which grabs a frame by only storing the 768 active video samples of each line of an NTSC signal for two consecutive fields. System operation may not be initiated without first having a supervisor unlock the personal computer and input a particular password. Further, each additional system operator must input their particular identification number into the personal computer whereby system security is maintained.
