Abstract
Disclosed are a valuable-file identifying method and an identifying device thereof. The identifying method and the identifying device store image data of a valuable file using a fast storage method for image data. The fast storage method for image data comprises: compulsively converting collected single-byte image data into long-integer image data; using N data masks which correspond to each other through a 'bitwise AND' operation to extract the long-integer image data in such a manner that N points are extracted from M*N points in each line and one point is extracted from L points in each column, where N is an integer greater than or equal to 2, L and M are all integers greater than or equal to 1; and integrating the data extracted respectively by N data masks through a 'bitwise OR' operation to obtain coded image data and store same. In conclusion, the present invention converts single-byte image data into long-integer image data, and extracts multipoint data at one time using a plurality of data masks which correspond to each other, reducing the number of operations, and achieving fast, compressed storage of images.
