Filed: 1995-03-17
Abstract: PURPOSE: To improve the coding efficiency of variable length coding by selecting plural kinds of scanning order methods and plural kinds of coding tales to make coding in matching with a characteristic of an image signal thereby coding quantization data. CONSTITUTION: An input image signal 1 is subject to block processing, an orthogonal transformation means 2 applies orthogonal transformation to the signal and a quantization means 3 quantizes the signal. A scanning means 6 scans an obtained quantization transformation coefficient based on plural scanning orders in a scanning order table 7 for each prescribed unit, a coding means 8 references plural coding tales in a coding table storage means 5 to encode plural kinds of scanning outputs from the scanning means 6. Since data outputs of coding data are generated by number of combinations between the plural scanning orders and plural coding tables, a selection means 9 selects adaptively a scanning order and a coding table among them.  Thus, even in the case of an image whose characteristic differs locally, optimum coding is attained for each prescribed unit and an efficient coding is realized.
