Abstract: For the display of images, notably X-ray images, the complete image of full resolution, usually consisting of a group of images, may be substantially larger than the size that can be reproduced on a display screen. In accordance with the invention, the overall group of images is displayed on the display screen as an auxiliary image in a strongly reduced scale, the size of the auxiliary image being dependent on the group of images. Via a frame which is reproduced in the auxiliary image and whose dimensions and position can be varied, a part of the group of images, i.e. one image or separate neighboring images, is selected and displayed on the overall display screen. When the frame is shifted in the auxiliary image, the part of the overall group of images which is displayed on the display screen is also automatically shifted.
