METHOD AND APPARATUS FOR CONVERTING AN INTERLACED VIDEO FRAME SEQUENCE INTO A PROGRESSIVELY-SCANNED SEQUENCE

摘要

Method and apparatus are disclosed for deinterlacing of an interlaced video frame sequence using interpolation estimations, such as spatial and temporal interpolations. Interpolations requiring a less accurate estimation of missing pixel values in the frames being deinterlaced, such that an interpolation may be performed with a minimum of error, are performed before interpolations which require a more accurate estimation of missing pixel values for performing an interpolation, such that estimates of missing pixel values are obtained with a minimum of error. Interpolation estimations are weighted combination for computing approximations of missing pixel values in accordance with the errors associated with the respective interpolations.
