1. An imaging system for controlling the flow of image data to a host computer, comprising:
- a gate having;
an input port for accepting a first series of electrical signals representing an image, wherein said first series of electrical signals has a first frame rate;
an output port for coupling said first series of electrical signals to a host computer; and
a control port for controlling the passage of said electrical signals from said input port to said output port to generate a second series of electrical signals having a second frame rate; and
means for sending command signals to said control port of said gate to enable said gate to pass said second series of electrical signals from said input port to said output port.

Abstract
An imaging system which incorporates a gate (which can be implemented either in hardware or software) for gating video signals to a host PC. The present invention allows fixed frame cameras to be used in applications which would otherwise require the host PC to have prohibitively large amounts of random access memory. However, by selecting predetermined frames of video data from a fixed frame output camera, the present invention simulates the effect of a variable frame rate camera.
