Abstract

Procédé et appareil de projection d'écran, terminal, dispositif, support informatique et produit-programme, qui se rapportent au domaine technique de la projection d'écran. Le procédé consiste : en réponse à une opération d'édition de première zone dans un état de projection d'écran, à déterminer une première zone d'édition de projection d'écran (201) ; si la première zone d'édition de projection d'écran contient un premier objet, à déterminer un premier contenu d'objet correspondant au premier objet en tant que premier contenu de projection d'écran (202) ; et à transmettre le premier contenu de projection d'écran à un dispositif de projection d'écran, de telle sorte que le dispositif de projection d'écran affiche le premier contenu de projection d'écran (203). Le procédé de projection d'écran peut empêcher la projection sur l'écran d'informations confidentielles inutiles, et améliorer la sécurité des informations de terminal.
