Abstract

La présente invention concerne un procédé de zoomage, un dispositif de zoomage, un équipement électronique et un support de stockage. Le procédé de zoomage comprend les étapes suivantes : appel d'un premier objectif en tant qu'objectif principal d'appareil de prise de vue pour obtenir une image de prévisualisation d'un objet à photographier, le premier objectif étant un objectif ayant le champ de vision maximal dans une pluralité d'objectif d'un équipement électronique ; réception d'une instruction de zoomage, l'instruction de zoomage comprenant au moins une indication de facteur de zoom exigé de zoomage d'objectif ; détermination, selon l'indication de facteur de zoom reçue, d'un deuxième objectif correspondant à l'indication de facteur de zoom en tant qu'objectif esclave d'appareil de prise de vues pour une commutation d'objectif, un facteur de zoom correspondant au deuxième objectif étant différent d'un facteur de zoom correspondant au premier objectif ; et réalisation d'un réglage du facteur de zoom sur la base du premier objectif et du deuxième objectif. Du fait qu'une commutation est effectuée du premier objectif ayant le champ de vision maximal à un objectif esclave d'appareil de prise de vues ayant un champ de vision plus petit que celui du premier objectif, lorsqu'un réglage de zoom numérique est effectué, une commutation vers l'objectif esclave d'appareil de prise de vues peut être achevée à un moment donné et, par conséquent la fluidité de la photographie d'image peut être améliorée.
