Abstract
A method includes aligning a first image frame of a first stream of images from a first image sensor and a further first image frame of a second stream of images from a second image sensor according to a first alignment, aligning a second image frame of the first stream of images and a further second image frame of the second stream of images according to the first alignment, obtaining a first stitched image frame by blending the aligned first image frame and further first image frame in a first blending area according to a first blending function, obtaining second stitched image frame by blending the aligned second image frame and the further second image frame in a second blending area according to a second blending function, and evaluating the first alignment from a difference pattern calculated from pixel values of the first stitched frame and the second stitched frame.
