Inventor: SHIYUDOU MASAMICHI
IPC: G06T3/40
Filed: 1978-07-14
Abstract: PURPOSE: To obtain the quantization pattern formed by magnify or reduce the original pattern of an optional quantization matrix size through the circuit constitution using the binary rate multiplier.  
     CONSTITUTION: The binary numbers corresponding to row number m and column number n of the original pattern are set to register 1 and 3, and the binary numbers corresponding to row number M and column number N of the pattern to be magnifid or reduced are set to register 2 and 4 respectively. Counter 5 is started to generate pulse train Pm and PM through gate group 7 and 8. Pattern memory 11 receives Pm and then reads the bit patterns of the row direction of the original pattern stored sequentially to signal line 110, and at the same time, pattern memory 12 writes the output on line 110 in sequence after receiving PM. And the contents of memory 11 is repeated and thinned according to magnification and reduction. When counter 5 reaches full counting, counter 6 starts subsequently to send out pulse train Pn and PM through gate group 9 and 10. Then the reading and writing of the column direction are carried out in the same way and between memory 11 and 12. And these operations are repeated sequentially.
