Original Abstract Submitted
A decoding unit decodes data corresponding to an N×M array of quantized coefficients from a bit stream. An inverse quantization unit derives orthogonal transform coefficients from the N×M array of quantized coefficients by using at least a quantization matrix. An inverse orthogonal transform unit performs inverse orthogonal transform on the orthogonal transform coefficients generated by the inverse quantization unit to generate prediction residuals corresponding to a block of a P×Q array of pixels. An inverse quantization unit derives the orthogonal transform coefficients by using at least a quantization matrix of an N×M array of elements, and the inverse orthogonal transform unit generates prediction residuals for the P×Q array of pixels having a size larger than the N×M array.
