摘要： An adaptive Motion JPEG encoding method is disclosed, including: acquiring a video sequence; encoding a current video frame of the video sequence into JPEG format based on a Huffman description table, generating encoded symbols corresponding to the current video frame and counting frequencies of occurrence of the encoded symbols corresponding to the current video frame; and updating the Huffman description table with Canonical Huffman encoding based on the frequencies of occurrence of the encoded symbols corresponding to the current video frame, the updated Huffman description table being used for encoding a next video frame adjacent to the current video frame of the video sequence into JPEG format. The adaptive Motion JPEG encoding method uses the correlation between the Huffman description tables of the adjacent frames to reduce the redundant information between the video frames. An adaptive Motion JPEG encoding system is also disclosed.
