The invention provides a data processing method based on a Huffman sheet; the method comprises the steps: establishing a binary tree array based on the Huffman sheet and decoding based on the binary tree array, wherein the binary tree array is a two-dimensional array, the first-dimensional array is the number of the layers of a binary tree and the second-dimensional array is the number of the nodes in each layer. The decoding based on the binary tree array comprises reading picture data, acquiring a node inquire code and correspondingly positioning to the corresponding nodes in the two-dimensional array according to the number of the layers of the two-dimensional array and the node inquire code; if the data at the corresponding position is valid, the node is a leaf node and the present inquire is finished; if no, continuously reading the picture data. By adopting the array manner, the operation of error-prone pointers and trees is avoided, the encoding is relatively simple and the debugging is relatively intuitive and simple compared with the binary tree manner.
