Abstract
(EN)
An image processing device of the present invention is provided with: a movement amount inference unit (22) that infers an amount of movement indicating the positional offset of a second image with respect to a first image, the second image being captured temporally after the first image and said inference being made using feature points extracted from each of the first image and second image; a decision unit (23) that, based on extracted feature points, makes a decision as to whether or not correction is to be performed using the amount of movement inferred by the movement amount inference unit (22); and an image correction unit (24) that, if the decision unit (23) decides that correction is to be performed using the amount of movement, corrects the positional offset among a plurality of images that have been temporally captured in succession, by using the amount of movement to correct the positional offset of the second image with respect to the first image.

Le dispositif de traitement d'image de la présente invention comprend : une unité d'inférence de quantité de mouvement (22) qui infère une quantité de mouvement indiquant le décalage positionnel d'une deuxième image par rapport à une première image, la deuxième image étant capturée temporairement après la première image, ladite inférence étant effectuée au moyen de points caractéristiques extraits de la première image et la deuxième image ; une unité de décision (23) qui, à partir des points caractéristiques extraits, détermine si une correction doit être effectuée ou non d'après la quantité de mouvement inférée par l'unité d'inférence de quantité de mouvement (22) ; et une unité de correction d'image (24) qui, si l'unité de décision (23) détermine que la correction doit être effectuée d'après la quantité de mouvement, corrige le décalage positionnel parmi une pluralité d'images qui ont été temporairement capturées successivement, en utilisant la quantité de mouvement pour corriger le décalage positionnel de la deuxième image par rapport à la première image.
