Abstract:
1. An encoding processing apparatus outputting encoded data obtained by performing redundancy-reducing encoding processing on image data, comprising; a first storing means for storing first encoded information calculated in the encoding processing performed on the image data, and second encoded information calculated from the first encoded information; a second storing means for storing a table indicating association relation between the first encoded information and the second encoded information; an arithmetic means for calculating the second encoded information by reading the first encoded information stored in the first storing means and searching the table stored in the second storing means, and storing the calculated second encoded information in the first storing means; a third storing means for storing by associating the first encoded information previously read from the first storing means by the arithmetic means and the second encoded information calculated from the first encoded information; a first control means for reading the second encoded information associated with the first encoded information from the third storing means and storing the information in the first storing means, when information same with the first encoded information read from the first storing means by the arithmetic means is stored in the third storing means; and a second control means for storing by associating the first encoded information with the second encoded information in the third storing means, when the arithmetic means calculates the second encoded information from the first encoded information read from the first storing means, wherein; the arithmetic means performs, only when the second encoded information calculated from the first encoded information read from the first storing means is not stored in the third storing means, processing of searching the table stored in the second storing means and calculating the second encoded information.
