Abstract
(EN)
Provided is a technology for automatically adjusting, using a perceptive model, a motion imparted to a projection object. This motion vector generation device is provided with: a first parameter generation unit which, on the basis of a perceptive difference between a projection result-reproducing image which is an image obtained in the case of photographing a projection object onto which a projection image obtained on the basis of a motion vector has been projected, and a warp image which is an image generated by distorting an image, obtained by photographing the projection object, by an amount of perceptive motion when the projection result-reproducing image is viewed, generates a first parameter which is a parameter for scaling the motion vector; and a motion vector reduction unit which scales the motion vector using the first parameter.

L'invention concerne une technologie pour ajuster automatiquement, à l'aide d'un modèle perceptif, un mouvement communiqué à un objet de projection. Le dispositif de génération de vecteur de mouvement selon l'invention comporte : une première unité de génération de paramètre qui, sur la base d'une différence perceptive entre une image de reproduction de résultat de projection qui est une image obtenue dans le cas d'une photographie d'un objet de projection sur lequel une image de projection obtenue sur la base d'un vecteur de mouvement a été projetée, et une image gauchie qui est une image générée par distorsion d'une image, obtenue par photographie de l'objet de projection, par une quantité de mouvement perceptif lorsque l'image de reproduction de résultat de projection est visualisée, génère un premier paramètre qui est un paramètre pour mettre à l'échelle le vecteur de mouvement ; et une unité de réduction de vecteur de mouvement qui met à l'échelle le vecteur de mouvement à l'aide du premier paramètre.
