Abstract
The present invention provides an image signal processing apparatus and a method thereof which perform double-speed conversion on images subjected to telecine conversion and in which a first field is specified based on difference values between pixel signal levels calculated with respect to respective detected pixels, write pixel positions which are shifted from the positions of the detected pixels in the vector directions of motion vectors are calculated in a field following the first field, the calculated write pixel positions are stored in correspondence with the motion vectors, interpolation pixel data is calculated from pixel data read from the first field in correspondence with the stored write pixel positions and motion vectors, and the calculated interpolation pixel data is written into the write pixel positions.
