ABSTRACT:
A video deinterlacing system receives interlaced video data at a non-deterministic rate and generates non-interlaced data as a function of the interlaced video data. The system includes processing units, some of which require clocking rates that differ from clocking rates required by other processing units. A timing generator responds to a base clock and to a data valid signal, that indicates arrival of a portion of the interlaced video data, to cause generation of a plurality of enable signals. Each of the enable signals operate to enable a corresponding one of the clocking rates required by the processing units. Video capture can be performed by causing capture of video frames that meet or exceed a specified quality level. The quality of the captured, still image, video can be improved by disabling certain enhancement functions performed to improve moving video images.
