Abstract:
1. A method utilizing a three-dimensional image interpolation algorithm to achieve frame rate conversions, which adjusts a resolution and a frame rate of received input audio/video (AV) data, generates a plurality of interpolated pixel values from a plurality of pixel values in a frame to fit the resolution and a frame rate of an AV player, and stores the new frame, wherein the method comprises the following steps: extracting two consecutive frames according to a playing order; determining a middle position according to the frame rate of the input AV data and the frame rate of the AV player; generating a plurality of interpolated pixel values for the middle position from corresponding pixel values of the two consecutive frames, the interpolated pixel values forming an interpolated frame; and storing the interpolated frame, wherein the interpolated pixel value is determined from the corresponding pixel values in the two consecutive frames using the following formula where P
