A video monitoring device (30) may include an input (31) for a video input signal, a display (33), and a video processor (32) coupled to the inpu t and the display. The video processor (32) may be for obtaining from the video input signal at least one parametric signal defining a curve, calculating derivative values for the curve, and displaying pixel intensity values on the display (33) based upon the derivative values so that more rapidly changing portions of the curve appear dimmer and more slowly changing portions of the curve appear brighter. |
