Abstract
A method for converting a frame rate of a video signal comprising a data enable signal by means of a first buffer and a second buffer is disclosed. The method comprises: alternatively accessing the first buffer and the second buffer according to a first frame rate; determining an accessing time point of the first and the second buffers according to the data enable signal; and accessing the buffer, which is one of the first and the second buffers and not accessed at the accessing time point, according to a second frame rate, wherein the second frame rate is faster than the first frame rate.

A method for converting a frame rate of a video signal comprising video data, a vertical synchronization signal and a data enable signal, the method comprising:
- alternatively accessing a first buffer and a second buffer according to a first frame rate;
- and
- accessing the buffer, which is one of the first and the second buffers and not accessed at a time point, according to a second frame rate, wherein the second frame rate is faster than the first frame rate, and the time point is in between the data enable signal and the vertical synchronization signal.
