Abstract: The device facilitates the verification of conformity between an anticipated digital image, or reference image, and a digital image actually obtained. The device implements a method that makes it possible to quickly and effectively distinguish the differences between a reference image and an obtained image. The device comprises receiving an input of two images, reference and obtained, and producing as output a single image, resulting from the merging of the two input images in which the portions common to both images are represented in shades of grey, the differences between the first and the second image being represented in green or red depending on whether they belong to the first or the second image.
