According to one embodiment, the apparatus of the embodiment of the invention has following modules. A decoder decodes a coded moving image signal to obtain a decoded moving image signal. A coding implementation information acquisition module acquires coding implementation information used when the coding is carried out. A motion detector obtains a motion detection output indicating a motion of an image. A coding distortion reduction module has a plurality of kinds of distortion reducing characteristics which reduce a plurality of kinds of coding distortions included in the decoded moving image signal. A coding distortion reduction controller controls the plurality of kinds of distortion reducing characteristics in accordance with the output of the coding implementation information and the motion detection output.
