Abstract
Target pixel blocks are picked up from a target image selected from a plurality of images picked up by an imaging device, motion vectors of these target pixel blocks are calculated between two images, and affine transformation coefficients for blur correction is calculated based on the motion vectors. Weighting coefficients are set for target pixel blocks based on a confidence level of the calculated motion vectors with respect to the image blur. For example, motion vectors in peripheral portion of the image is usually large in size, so that the confidence level of these may be enhanced.
