Abstract
(EN)
An imaging method, an imaging device (300), an electronic apparatus (1000), and a medium. The imaging method is applied to the electronic apparatus (1000). The electronic apparatus (1000) comprises a wide-angle camera (30) and multiple telephoto cameras (20). The imaging method comprises: obtaining an image collected by the wide-angle camera (30) as a reference image (P1); obtaining the images respectively collected by the multiple telephoto cameras (20) as pre-processed images (P2), wherein the visual field areas of the multiple preprocessed images cover that of the reference image (P1), and exceed that of the reference image (P1); and synthesizing the reference image (P1) and the multiple preprocessed images (P2) to obtain a target image (P3). By means of the imaging method of the implementations of the present application, the visual field areas of the multiple preprocessed images (P2) cover and exceed that of the reference image (P1), so that the target image (P3) synthesized from the multiple preprocessed images (P2) and the reference image (P1) can realize an ultra-wide angle effect, and it is beneficial for improving user experience.

L'invention concerne un procédé d'imagerie, un dispositif d'imagerie (300), un appareil électronique (1000), et un support. Le procédé d'imagerie est appliqué à l'appareil électronique (1000). L'appareil électronique (1000) comprend une caméra grand angle (30) et plusieurs caméras à téléobjectif (20). Le procédé d'imagerie comprend les étapes consistant à : obtenir une image collectée par la caméra grand angle (30) en tant qu'image de référence (P1); obtenir les images collectées respectivement par les multiples caméras à téléobjectif (20) en tant qu'images pré-traitées (P2), les zones de champ visuel des multiples images prétraitées couvrant celle de l'image de référence (P1), et dépassant celle de l'image de référence (P1); et synthétiser l'image de référence (P1) et les multiples images prétraitées (P2) afin d'obtenir une image cible (P3). Au moyen du procédé d'imagerie des modes de réalisation de la présente invention, les zones de champ visuel des multiples images prétraitées (P2) recouvrent et dépassent celle de l'image de référence (P1), de sorte que l'image cible (P3) synthétisée à partir des multiples images prétraitées (P2) et de l'image de référence (P1) puisse réaliser un effet d'angle ultra-large, et il est avantageux d'améliorer l'expérience de l'utilisateur.
