This abstract first appeared for US patent application 18231898 titled 'PREDICTION IMAGE GENERATION DEVICE, MOVING IMAGE DECODING DEVICE, AND MOVING IMAGE CODING DEVICE

==Simplified Explanation==

The patent application describes a method to improve coding efficiency in image processing.
* A motion compensation filter unit is used to process an image that has been modified by applying a motion vector to a reference image.
* The motion compensation filter unit applies filter coefficients, denoted as mcFilter[i][k], to the motion vector applied image.
* The filter coefficients mcFilter[i][k] are calculated using other filter coefficients mcFilter[p][k] and mcFilter[q][k], where p and q are not equal to i.


==Original Abstract Submitted==

Coding efficiency is improved. A motion compensation filter unit acts on a motion vector applied image obtained by acting a motion vector on a reference image. The motion compensation filter unit causes filter coefficients mcFilter[i][k] designated by a phase i and a filter coefficient position k to act on the motion vector applied image. The filter coefficients mcFilter[i][k] includes filter coefficients calculated by using filter coefficients mcFilter[p][k] (p≠i) and filter coefficients mcFilter[q][k] (q≠i).
