Claim 11:
12. A method of a video processor, configured to perform the following steps:
receiving a series of input frames;
determining an expected input gap value according to a relativity of an input frame rate of the series of input frames and an output frame rate of a series of output frames output by the video processor;
determining whether an actual input gap value is different from the expected input gap value;
calculating a phase step when the actual input gap value is determined to be different from the expected input gap value to obtain the phase step which is different from a regular phase step determined based on the relativity of the input frame rate and the output frame rate; and
generating an interpolated frame to be output as an output frame among the series of output frames based on a selected frame set by using the calculated phase step.
