In a 3D image generating apparatus 1 depth values (Z-value) of pixels are calculated on the basis of grayscale values of 2D image data. Next, a reverse determination, smoothing, distribution adjustment, local adjustment, and the like are performed on the Z-values. Next, parallaxes of pixels are determined on the basis of the Z-values of the pixels finally obtained, and the pixels are displaced acceding to the parallaxes, so as to generate data of a stereographic image.

Cette invention se rapporte à un dispositif de formation d'images à vision tridimensionnelle (1), qui calcule une valeur de profondeur (valeur Z) en fonction de la valeur d'échelle des gris des données d'images bidimensionnelles. Cette valeur Z est soumise à un traitement d'évaluation inverse, à un traitement de lissage, à un traitement de correction de distribution, à un traitement de correction locale et similaire. Une parallaxe est déterminée en fonction de la valeur Z ainsi obtenue et chaque pixel est déplacé sur l'étendue de la parallaxe, générant ainsi des données d'images à vision tridimensionnelle.
