The invention relates to the technical field of data compression and storage, in particular to a driving digital video compression processing method, which comprises the following steps of: segmenting each video frame of a driving digital video into a plurality of image blocks, and obtaining a to-be-coded sequence, a run length coding sequence, a gray sequence and a run length sequence of each image block, the method comprises the steps of obtaining a gray scale sequence and a run length sequence of each image block, further obtaining a run length advantage of each image block, selecting a compression mode of the image blocks according to the run length advantages, and when the run length advantages of the image blocks are greater than 0, constructing a gray scale normal form Huffman tree and a run normal form Huffman tree according to the gray scale sequence and the run length sequence so as to obtain a Huffman run tree; and coding the run length coding sequence of the image block according to the Huffman ru
