Abstract

L'invention concerne un système de capture d'image, un dispositif de capture d'image, un procédé de capture d'image et un programme de capture d'image qui permettent de sélectionner, à partir d'une unité de mémoire dans laquelle une pluralité de photographies de référence sont mémorisées, une photographie de référence servant de modèle de composition, et d'effectuer une imagerie à l'aide de la photographie de référence sélectionnée. Une pluralité d'images en tant que références de composition sont acquises (S12) ; une condition de tri est définie par rapport à une pluralité d'éléments de données d'image (S14, S16) ; la pluralité d'éléments de données d'image sont triés en fonction de la condition de tri (S18) ; des images triées sont affichées dans l'ordre des rangs de tri (S20) ; une image est sélectionnée parmi la pluralité d'images affichées (S22) ; une condition de capture d'image pour des données d'image correspondant à l'image sélectionnée est définie, et des instructions sont données concernant une position de capture d'image et une direction de capture d'image qui permettent la capture de la même image que l'image sélectionnée (S24) ; et l'imagerie est réalisée (S28).
