Title: Adaptive orthogonal transformation encoding device
Inventor: SAI NARIYOSHI
IPC: H04N19/137
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To further effectively solve the problem that image quality is degraded by erroneous mode selection by predicting variable length encoded data based on data in a frequency area and adaptively selecting a mutually different orthogonal transformation system by a predicted result. SOLUTION: This encoder is composed of delay devices 21 and 23, a computing element 22, an 8×8 DCT device 24, a 4×8 DCT device 25, scanning parts 26 and 27, counters 28-33, a mode selection part 30 and a multiplexer 31. Then, orthogonally transformed data are analyzed, an optimum orthogonal transformation mode is selected and especially the orthogonal transformation mode is selected based on the number of continuous '0' present in the orthogonal transformation and the number of times of change from '0' to a value not '0' for the respective picture element blocks of 8×8 size. Thus, the optimum orthogonal transformation mode is selected based on the further accurate prediction of a data amount generated by the variable length encoder of a post stage and the problem that the image quality is degraded by the erroneous mode selection is further effectively solved.
