Abstract

La présente invention permet d'assurer une capture nette d'un sujet par détection d'un tremblement pendant la prise de vue du sujet et par déplacement de l'objectif dans un sens pour compenser le tremblement. Selon la présente invention, une bobine et un aimant sont utilisés, et lorsqu'un courant est appliqué sur la bobine, le champ magnétique généré par l'aimant et le champ magnétique généré par la bobine amènent la bobine à se déplacer dans un sens perpendiculaire au sens de l'axe optique de l'objectif.
