Embodiment
With reference to schematic diagram and concrete operations embodiment, the invention will be further described.
Computer picture scanning control system of the present invention include iris scan part, data buffer storage part, control unit and
Display unit, as shown in figure 1, iris scan part, data buffer storage part and control unit are sequentially connected, control unit and display
Part is connected.
It is preferred that, iris scan part be image recorder, image recorder have video collector, vision signal it is defeated
Incoming interface and output interface, video collector connection control unit, input interface connection video collector, output interface connection number
According to caching part.Display unit is to have a display interface on the LCDs of computer, LCDs.Video collector
For forward type, the top of computer display is placed in, the top of display, video can be fixed or removably be mounted in
The critical piece of collector is camera, and the user images before display recorded into inside by sensitive chip inside camera
