More appropriate filtering is executed by determining whether a filter is to be applied to a luminance signal and a chrominance signal, individually. A moving-picture decoding apparatus includes a decoding unit for decoding input coded data to generate a quantized transform coefficient and filter information, an inverse-transform/inverse-quantization unit for executing inverse-quantization and inverse-transform on the quantized transform coefficient to generate a prediction error picture, a decoded-picture generation unit for generating a decoded picture using the prediction error picture and a predicted picture, a luminance filter processing unit for applying a luminance filter to the luminance signal of the decoded picture based on luminance filter information to generate the luminance signal of a restored picture, and a chrominance filter processing unit for applying a chrominance filter to the chrominance signal of the decoded picture based on chrominance filter information to generate the chrominance signal of the restored picture. |
