Abstract

L'invention concerne un procédé de prise de vue pour une trace de déplacement d'un objet, un terminal mobile et un support de stockage informatique. Le procédé de prise de vue pour une trace de déplacement d'un objet comprend les étapes suivantes : une fois que la prise de vue commence, afficher une interface d'ajustement de paramètre sur une fenêtre de prise de vue pour un utilisateur pour ajuster un paramètre de prise de vue ; recevoir le paramètre de prise de vue ajusté par l'utilisateur, et acquérir de manière successive, selon le paramètre de prise de vue ajusté, des images de déplacement d'un objet par l'intermédiaire d'un appareil de prise de vue ; et réaliser une composition d'image selon toutes les images de déplacement acquises de l'objet pour générer une image composite correspondant à la trace de déplacement de l'objet. Dans un processus de prise de vue, une interface d'ajustement de paramètre pour ajuster un paramètre de prise de vue est affichée, de façon à acquérir des images de déplacement d'un objet selon le paramètre de prise de vue ajusté, et les composer en une image composite correspondant à la trace de déplacement de l'objet ; et un utilisateur peut ajuster le paramètre de prise de vue selon des exigences réelles dans le processus de prise de vue, de telle sorte qu'une image de prise de vue de la trace de déplacement de l'objet peut satisfaire des exigences personnalisées de l'utilisateur.
