Abstract
An inverse quantizing device includes memories which are addressed by input quantized coefficients and quantization levels and store resultant data of inverse quantization in groups such as intra DC, intra AC and non-intra. A control section discriminates the group of an input data to be inverse-quantized according to input block-type and block-strobe signals, selects one of the memories according to the discriminated result, and controls the selected memory to output the resultant data of inverse quantization stored therein. According to the device, real time processing of the input data is achieved with its simplified construction.
