<p>PROBLEM TO BE SOLVED: To provide an inverse quantization circuit adapted to MPEG-4 and the like, which can bring decrease in power consumption and size reduction of a chip mounted on the inverse quantization circuit, by decreasing the number of wiring. SOLUTION: At a double increment unit 5, processing is conducted to determine an OR processed value for a section of the bit 11 and the bit 10 of|QF[i] (AC/DC quantization coefficient)|as the value of the bit 11 of an output A[i], a section from the bit 9 to the bit 0 of|QF[i]|as a section from the bit 10 to the bit 1 of the output A[i], and the bit 0 of the output A[i] as '1'.</p> |
