Abstract: L'invention concerne un procédé et un dispositif de codage/décodage d'image. Lorsqu'une image doit être codée dans une séquence vidéo devant être codée, il est possible de sélectionner une image de référence à partir d'au moins une image de base de connaissances d'un ensemble d'images de base de connaissances. Lorsqu'une image de référence ne peut être sélectionnée que pour une image devant être codée à partir d'un fragment d'accès aléatoire où celle-ci se trouve, il est possible d'ajouter le nombre d'images de référence auxquelles l'image devant être codée peut se référer, à savoir, étendre une plage candidate d'une image de référence d'une image devant être codée dans une certaine mesure, ce qui améliore l'efficacité de codage d'image dans une certaine mesure. Des données de flux de code d'une image devant être codée comprennent des informations d'identification pour identifier une image de référence de l'image devant être codée. Par conséquent, même si l'image de référence est codée en tant qu'une image d'accès aléatoire sur la base du codage dans un mode intra-trame complet ou un codage inter-trame, après qu'une extrémité de décodage a reçu des données de flux de code, l'extrémité de décodage peut trouver une image rétablie de l'image de référence correspondant exclusivement à celle-ci d'après les informations d'identification concernant l'image de référence, ce qui permet d'obtenir le décodage correct d'une image.
