Abstract:
1. A system comprising: an input configured to receive a sequence of input pictures at a first frame rate; and a frame rate conversion entity configured to generate a sequence of output pictures at a second frame rate from the sequence of input pictures, wherein the output pictures comprise a sequence of original output pictures and interpolated pictures, wherein to generate a first interpolated picture from a first original input picture, the frame rate conversion entity attempts to detect a presence of repetitive patterns in the first original input picture; wherein responsive to detecting the presence of repetitive patterns within a pixel collection in the first original input picture, the frame rate conversion entity generates the first interpolated picture by copying the pixel collection from the first original input picture to positions in the first interpolated picture without any translation; and wherein responsive to failing to detect the presence of repetitive patterns in the first original input picture, the frame rate conversion entity generates the first interpolated picture by translating collections of pixels from the first original input picture by a scaled motion vector corresponding to a relative temporal position of the first interpolated picture from one of the original output pictures to a subsequent one of the original output pictures.
