ABSTRACT:
To acquire a high-resolution frame from a plurality of frames sampled from a video image, it is necessary to obtain a high-resolution frame with reduced picture quality degradation regardless of motion of a subject included in the frame. Because of this, between a plurality of contiguous frames FrNand FrN+1, there is estimated a correspondent relationship. Based on the correspondent relationship, the frames FrN+1and FrNare interposed to obtain first and second interpolated frames FrH1and FrH2. Based on the correspondent relationship, the coordinates of the frame FrN+1are transformed, and from a correlation value with the frame FrN, there is obtained a weighting coefficient α(x°, y°) that makes the weight of the first interpolated frame FrH1greater as a correlation becomes greater. With the weighting coefficient, the first and second interpolated frames are weighted and added to acquire a synthesized frame FrG.
