Abstract:
An image decoding method including a decoding process for decoding coded image data which are obtained by coding image data of each frame for displaying a predetermined image, to generate decoded image data, and a display process for displaying a decoded image on the basis of the decoded image data, whereinsaid decoding process includes: an intra-frame decoding process of decoding coded image data of a processing target frame which is to be decoded, without referring to decoded image data of an already processed frame the decoding process of which has been completed; and an inter-frame decoding process of decoding coded image data of a processing target frame which is to be decoded, with referring to decoded image data of an already processed frame the decoding process of which has been completed, and when the decoded image data of the already processed frame as a reference frame which is to be referred to in the decoding of the coded image data of the processing target frame are undefined, said inter-frame decoding process refers to preset image data for displaying a preset image in place of decoded image data of the reference frame.
