Abstract
A method of processing a digital image (medical, radiograph) in order to enhance viewing of the image when it is presented for display on a display device (video monitor). An original medical image is digitized and precompensation applied to the digital values to optimize the information content and detail at a CRT, for example. The luminance dynamic range and the spatial frequency content of the original image are reduced to present the most usable image on a display device. The characteristics of the human visual system and the ambient light incident on a calibrated display are factors in the final precompensation of the image.
