Abstract
A method and apparatus for determining the status of frame data transmission from an imaging device. According to one aspect of the invention, a graphics controller interfaces with a host and an imaging device, preferably a camera. A count value is specified, preferably by the host. Frame data received from the imaging device are counted to determine an actual count. A comparison is made between the actual count and the count value. Preferably, responsive to the comparison, an indication signal is generated for interrupting the host.
