Abstract: Content comprising a sequence of original frames at a first frame rate is up-converted to a second, higher, frame rate. Intermediate frames are calculated for temporal positions spaced between temporal positions of the original frames. An output sequence at the second frame rate comprises a repeating pattern of frames and, within each repetition of the pattern, there is: at least one original frame; at least one intermediate frame which is repeated; and at least one frame which is not repeated. The method is suitable for applications where an up-conversion factor is required in the frame rate, such as an up-conversion factor of five to up-convert from the 24 Hz frame rate used for film-based content to the 120 Hz frame rate used by displays. The output sequence can use all of the original frames to reduce detail flicker.
