摘要： An image data decoding apparatus according to an embodiment of the invention includes: a variable length coder/decoder for decoding compressed image data to output a quantization coefficient; a non-zero coefficient detector for examining whether or not the quantization coefficient includes a non-zero coefficient for each examination unit; a quantization coefficient FIFO for storing, if the examination unit includes one or more non-zero coefficients, the quantization coefficient of the examination unit as a significant coefficient; a significant coefficient flag FIFO for storing a significant coefficient flag that indicates whether or not the examination unit is a significant coefficient, and a zero coefficient generator for reconstructing the quantization coefficient based on the significant coefficient flag and significant coefficient.

摘要： In an inversely quantizing method of determining an inverse quantization value Y from an original quantization index value X, scale conversion is performed to a quantization index value X1 as at least a part of the original quantization index value X to produce first and second values which indicate the quantization index value X1. Then, first and second tables are referred to based on the first and second values, to determine third and fourth values corresponding to the first and second values, respectively. Then, an inverse quantization value Y is determined from the third and fourth values.
