Device for selectively passing video frames from a signal series having a first frame rate to obtain a signal series having a second frame rate

摘要

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.
