Abstract

La présente demande concerne le domaine technique de l'électronique et divulgue un procédé de photographie et un dispositif électronique, capables d'améliorer l'expérience de photographie d'un utilisateur lors d'un zoomage à un grossissement élevé. Le procédé comprend les étapes selon lesquelles un dispositif électronique : reçoit un premier actionnement et, en réponse à ce premier actionnement, démarre un appareil photographique dont le grossissement de zoom est un premier grossissement de zoom et affiche une interface de photographie comprenant une première boîte de recherche de vue qui comprend une première image de prévisualisation ; reçoit un deuxième actionnement et, en réponse à ce deuxième actionnement, ajuste le grossissement de zoom de l'appareil photographique sur un deuxième grossissement de zoom, et zoome sur la première image de prévisualisation affichée dans la première boîte de recherche de vue et affiche celle-ci en tant que deuxième image de prévisualisation ; et reçoit un troisième actionnement et, en réponse à ce troisième actionnement, ajuste le grossissement de zoom de l'appareil photographique sur un troisième grossissement de zoom, affiche une troisième image de prévisualisation dans la première boîte de recherche de vue, et affiche une seconde boîte de recherche de vue dans la première boîte de recherche de vue. La première image de prévisualisation est une image de recherche de vue selon le premier grossissement de zoom, la deuxième image de prévisualisation est une image de recherche de vue selon le second grossissement de zoom, la troisième image de prévisualisation est une image de recherche de vue selon un grossissement de zoom prédéfini, et une quatrième image de prévisualisation est une image de recherche de vue selon le troisième grossissement de zoom.
