IT Home reported on November 4 that Xiaomi's REDMI K100 phone was officially released on October 27. According to an introduction published today by Xiaomi Technology's official account, the phone adds an AI feature for 3D camera movements: select a still photo from the gallery, and AI can generate a video with wide-angle 3D camera movements. The camera can orbit, move in and out, and tilt, while the facial features, hairstyle, and clothing of people in the image remain consistent throughout.
IT Home learned from Xiaomi Technology's official account that the feature is powered by WorldCast, a visual generation framework Xiaomi presented in a recently published paper. By interpreting the image's depth structure, it reconstructs a flat photo as a three-dimensional scene and creates a virtual, realistic camera path through it. This makes the camera move as though the scene were actually being filmed, while consistently preserving the main subject's appearance as the camera moves.
Xiaomi Technology's official account said WorldCast is another breakthrough for Xiaomi in controllable visual generation. It does more than add another feature to the REDMI K100's gallery: more importantly, it has established a method, dataset, and evaluation approach. Building on this foundation, the team will further explore more complex camera movements, longer continuous generation, and controllable 4D video generation technology, among other areas.
