    摘要： A digital video acquisition system including a plurality of image processors (30A; 30B) is disclosed. A CCD imager (22) presents video image data on a bus (video_in) in the form of digital video data, arranged in a sequence of frames. A master image processor (30A) captures and encodes a first group of frames, and instructs a slave image processor (30B) to capture and encode a second group of frames presented by the CCD imager (22) before the encoding of the first group of frames is completed by the master image processor. The master image processor (30A) completes its encoding, and is then available to capture and encode another group of frames in the sequence. Video frames that are encoded by the slave image processor (30B) are transferred to the master image processor (30A), which sequences and stores the transferred encoded frames and also those frames that it encodes in a memory (36A; 38). The parameters of the encoding operation can be dynamically adjusted, for example in response to the nature of the video sequences being captured.

A CCD imager (22) presents video image data on a bus (video_in) in the form of digital video data, arranged in a sequence of frames. A master image processor (30A) captures and encodes a first group of frames, and instructs a slave image processor (30B) to capture and encode a second group of frames presented by the CCD imager (22) before the encoding of the first group of frames is completed by the master image processor. The master image processor (30A) completes its encoding, and is then available to capture and encode another group of frames in the sequence. Video frames that are encoded by the slave image processor (30B) are transferred to the master image processor (30A), which sequences and stores the transferred encoded frames and also those frames that it encodes in a memory (36A; 38).
