Abstract:
1. An image processing method of generating an integrated picture corresponding to a target picture, using the target picture and a plurality of reference pictures, the target picture being one of a plurality of pictures which are sequentially inputted every predetermined period, and the reference pictures being included in the sequentially inputted pictures and being temporally positioned prior or subsequent to the target picture, said image processing method comprising: estimating a motion amount between a segment of the target picture and a segment of each of the reference pictures with sub-pixel precision; calculating, by using at least a part of the estimated motion amounts, a global motion parameter which represents dominant motion in the whole target picture, and calculating an in-stabilized variant component based on a history of the global motion parameter; calculating a stabilized motion amount for the target picture, based on the in-stabilized variant component; calculating respective stabilized motion amounts for the respective reference pictures, based on the motion amounts and the in-stabilized variant component; mapping pixels of the reference pictures onto a space for the integrated picture, after shifting the pixels based on the stabilized motion amounts of the reference pictures; mapping pixels of the target picture onto the space, after shifting the pixels based on the stabilized motion amount of the target picture; and generating, from the pixels of the space, the integrated picture that has pixels whose number is determined using one of a magnification ratio and a predetermined number of pixels, and which are positioned equally spaced apart.
