Method and apparatus for interpolating an ordered sequence of input images 401 such as video input, to obtain a new image 404 at a required position in the sequence that does not align with an input image wherein interpolation-related impairments are reduced by interpolating at least a part of said new image at a position that is offset from its present position. Preferably the motion compensated interpolation 402 generates motion vectors having a vector confidence value 407 and has a motion compensated interpolation to use the motion vectors to interpolate a new image from two input images at a position determined by a phase control signal 403. The vector confidence values are used to generate an interpolation confidence measure. The phase control signal is then modified to offset the position at which the new image is interpolated toward the position of the closer of the two input images as said measure of the confidence value reduces. |
