    Abstract: A video frame processing method, which comprises: (a) capturing at least two video frames via a multi-view camera system comprising a plurality of cameras; (b) recording timestamps for each the video frame; (c) determining a major camera and a first sub camera out of the multi-view camera system, based on the timestamps, wherein the major camera captures a major video sequence comprising at least one major video frame, the first sub camera captures a video sequence of first view comprising at least one video frame of first view; (d) generating a first reference video frame of first view according to one first reference major video frame of the major video frames, which is at a reference timestamp corresponding to the first reference video frame of first view, and according to at least one the video frame of first view surrounding the reference timestamp; and (e) generating a multi-view video sequence comprising a first multi-view video frame, wherein the first multi-view video frame is generated based on the first reference video frame of first view and the first reference major video frame.

    Abstract: A video processing system includes a data buffer and a storage controller. The data buffer is shared between a plurality of in-loop filters, wherein not all of the in-loop filters comply with a same video standard. The storage controller controls data access of the data buffer, wherein for each in-loop filter granted to access the data buffer, the data buffer stores a partial data of a picture processed by the in-loop filter. Another video processing system includes a storage device and a storage controller. The storage controller adaptively determines a size of a storage space according to a tile partition setting of a picture to be processed by an in-loop filter, and controls the storage device to allocate the storage space to serve as a data buffer for storing data of the in-loop filter.
