Abstract
(EN)
Embodiments of the present invention disclose a supplementary lighting method for user self-shooting, a two-screen terminal, and a computer readable storage medium, pertaining to the technical field of smart image capture. The method comprises: upon detecting a self-shooting operation performed by a user via a first screen of a two-screen terminal, acquiring brightness information of a surrounding environment of the first screen; determining whether the brightness information is lower than a pre-determined brightness threshold; and if so, adjusting an angle and/or brightness of a second screen of the double-screen terminal until the brightness information of the surrounding environment of the first screen reaches an optimal supplementary lighting effect. The embodiments of the present invention improve the outcome of self-shooting without influencing the display of an image preview on a self-shooting screen, thereby improving user experience.

Selon certains modes de réalisation, la présente invention relève du domaine technique de la capture d'images intelligente et concerne un procédé d'éclairage supplémentaire pour prise d'autoportrait photographique par un utilisateur, un terminal à deux écrans, et un support de stockage lisible par ordinateur. Le procédé consiste à acquérir, lors de la détection d'une opération de prise d'un autoportrait photographique effectuée par un utilisateur via un premier écran d'un terminal à deux écrans, des informations de luminosité d'un environnement entourant le premier écran ; à déterminer si les informations de luminosité sont inférieures à un seuil de luminosité prédéfini ; et si tel est le cas, à ajuster un angle et/ou une luminosité d'un second écran du terminal à deux écrans jusqu'à ce que les informations de luminosité de l'environnement entourant le premier écran atteignent un effet d'éclairage supplémentaire optimal. Les modes de réalisation de la présente invention améliorent le résultat de la prise d'autoportraits photographiques sans effet sur l'affichage d'une prévisualisation d'image sur un écran de prise d'autoportrait, ce qui améliore l'expérience de l'utilisateur.
