Abstract

The present invention is related to an image stitching method. It is further related to an image stitching device and to a computer readable medium carrying instructions for performing such method. The method according to the invention includes determining a pixel value of a pixel at an interpolation position in the region to be stitched using pixel values of corresponding pixels in a plurality of sub-images. According to the invention, the interpolation position corresponds to a weighted sum of positions of the corresponding pixels. The weighting factor for the position of a corresponding pixel in a given sub-image depends on a relative distance of at said interpolation position to a border of the region to be stitched associated with that sub-image.
