An image generation method for generating image information of an image C by using an image A and an image B having a resolution higher than that of image A. Image C having the same resolution as image B is generated by enlarging image A; presence or absence of a point in image B corresponding to each pixel position of image C and the position of the relevant corresponding point are estimated; and to each pixel position in image C for which it is estimated that there is a corresponding point, image information of the corresponding position in image B is assigned. It is possible to generate image information at each pixel position in image C for which it is estimated in the corresponding point estimation that there is no corresponding point, by using the image information assigned according to an estimation result that there is a corresponding point.

Un procédé de génération d'image consiste à générer des informations d'image d'une image (C) à partir d'une image (A) et d'une image (B) ayant une résolution supérieure à celle de l'image (A), agrandit l'image (A) de façon à créer l'image (C), qui a la même résolution que l'image (B) ; évaluer chaque position de pixel de l'image (C), la présence ou l'absence de son point correspondant dans l'image (B) et une position du point correspondant ; et définir les informations d'image de la position correspondante dans l'image (B) à la position de pixel dans l'image (C), si l'unité d'évaluation de point correspondant constate que le point correspondant existe. Les informations d'image de la position de pixel dans l'image (C) dans laquelle l'absence du point correspondant est évaluée par l'unité d'évaluation de point correspondant peuvent être créées à partir des informations d'image dans lesquelles l'existence du point correspondant est évaluée et définie.
