Abstract:
1. A frame rate conversion apparatus for three-dimensional (3D) stereo display, comprising: a storage unit; an input controller, for inputting an input frame sequence to the storage unit according to an input frame rate, the input frame sequence comprising a plurality of frame pairs each having a left frame and a corresponding right frame; and an output controller, for alternately outputting one of the left frames and one of the right frames from the storage unit according to an output frame rate and left/right frame information associated with the frame pairs in the storage unit to form an output frame sequence, wherein the output controller successively outputs one of the left frames a predetermined number of times when outputting the one of the left frames, and successively outputs one of the right frames the predetermined number of times when outputting the one of the right frames, wherein the output controller and the input controller do not simultaneously output from and input to a same frame buffer, wherein the output controller selects a frame buffer to which one of the right frames has been most recently inputted by the input controller to output after outputting one of the left frames, wherein the output controller selects a frame buffer to which one of the left frames has been most recently inputted by the input controller to output after outputting one of the right frames, and wherein alternately outputting one of the left frames and one of the right frames from the storage unit comprises selectively skipping at least one frame of the input frame sequence.
