Patent ID: 8861595

Claim:
A method for converting an input video sequence operating at a variable frame-rate into an output video sequence operating at a constant frame-rate, the method comprising: storing digital images of said input video sequence in a buffer; fetching the digital images from the buffer at an emptying rate; adjusting the emptying rate as a function of the number of digital images of said input video sequence stored in the buffer to form an intermediate video sequence; interpolating using a motion-compensated interpolation algorithm on said intermediate video sequence to form said output video sequence having a constant frame rate that is interpolated from the adjusted emptying rate; wherein: if the emptying rate is equal to said constant frame-rate no interpolation is carried out; if the emptying rate is less than said constant frame-rate the interpolation generates a number of images greater than the images fetched from said temporarily stored input video sequence; and if the emptying rate is higher than said constant frame-rate the interpolation generates a number of output images smaller than that of the images fetched from said temporarily stored input video sequence.
