Abstract: The inventive method for viewing of a multi-spectral image by an operator uses contrast optimisation by Fischer projection. The Fischer projection is determined and applied within a window (F1, F2, F3, ...) that is smaller than a display screen matrix (1) used by the operator. The window is moved for successive updates of a depiction of the image that is displayed, while creating a remanence of the positions of the earlier windows and elements that were exposed in some of said earlier windows. The implementation of the method is particularly simple and intuitive for the operator, so as to improve the reliability and effectiveness of his or her monitoring.

Abstract: In a method for displaying a multispectral image, a plurality of target regions (T
1 , T
2 , T
3 , T
4 ) is selected within an analysis window (FA), and a Fisher projection is performed separately for each target region in order to optimize a contrast in the multispectral image in the analysis window. Basic enhanced contrast images are thus obtained for all the target regions in the same analysis window, whereupon a combined image is formed from the basic images and is displayed on an image display unit. The invention allows multispectral images to be displayed better, including for specific arrangements of the content of a scene captured in the multispectral image.
