Abstract
Techniques, apparatus and system for correcting moving image wavering are disclosed. An apparatus includes a selecting unit to select at least one reference macroblock from an input image of a first frame and to select at least one search area from an input image of a second frame. The selected at least one search area corresponds to the at least one reference macroblock. The apparatus includes an operating unit to communicate with the selecting unit and to perform a statistical operation by matching the at least one reference macroblock of the first frame to each of search blocks included in the at least one search area of the second frame. The apparatus comprises a vector calculating unit to communicate with the operating unit and to calculate a motion vector to correct an output image of the second frame based on a resultant value of the statistical operation.
