ABSTRACT:
A method of operating a display including providing a display; acquiring an image of a structure by measuring, for each of a plurality of elements, a magnitude representing an element of the structure; providing a plurality of contrast setting control buttons including a first contrast setting button that directly and independently modifies dark parts of the image of the structure and a second contract setting button that directly and independently modifies light parts of the image of the structure; digitizing the magnitudes according to a direct mode by assigning a digitized value d representing the measured magnitude of each of the elements; displaying a direct image by assigning a luminosity l corresponding to the digitized value d of each of the elements and transmitting to the display the luminosity l of each of the elements; transforming the direct image to a transformed image by assigning to each the of elements a digital value i which corresponds to the digitized value d of each of the elements; and displaying the transformed image by assigning to each of the elements a luminosity m corresponding to the digital value i of each of the elements and transmitting to the display the luminosity m of each of the elements, the digital value d of each of the elements is converted into the digital value i of each of the elements according to a reversal function f, the reversal function f having a slope -b for zero values of d and a slope -1/a a for maximum values of d, so as to transform the darkest and the most luminous parts of the direct image, the contrast setting control buttons act directly on slope -b and slope -1/a and the reversal function f is determined on the basis of slope -b and slope -1/a.
