Abstract
One block of non-zero coefficients obtained through the decoding of the entropy decoding unit 2024 is stored in the coefficient storage unit 121 in accordance with positional coordinates calculated by the non-zero coefficient scanning order calculation unit 2023a and the non-zero coefficient position conversion unit 2023b. The stored non-zero coefficients are then inverse quantized by the inverse quantization unit 2022. The non-zero coefficient range calculation unit 122 specifies a region of the coefficient storage unit 121 in which the non-zero coefficients are stored. The calculation order control unit 123 controls the inverse DCT unit 2021 to only perform an inverse DCT (discrete cosine transform) for non-zero coefficients located in the specified region.
