Abstract

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.

Claims (10)

1. A video monitoring device comprising:
an input for a video input signal;
a display; and a video processor coupled to said input and said display 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 said display 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.
2. The video monitoring device of Claim 1 wherein said video processor further performs an accumulation so that each displayed pixel intensity value is based upon a current pixel intensity value and at least one prior pixel intensity value.
3. The video monitoring device of Claim 1 wherein said video processor further performs an intensity modulation so that each displayed pixel intensity value is based upon a modulated derivative value.
4. The video monitoring device of Claim 1 wherein said video processor further displays on said display the video signal.
5. The video monitoring device of Claim 1 wherein said video processor comprises a Graphics Processing Unit (GPU).
6. A video processing method comprising:
obtaining at least one parametric signal defining a curve from a video input signal;
calculating derivative values for the curve; and displaying pixel intensity values on a display 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.
7. The method of Claim 6 further comprising performing an accumulation so that each displayed pixel intensity value is based upon a current pixel intensity value and at least one prior pixel intensity value.
8. The method of Claim 6 further comprising performing an intensity modulation so that each displayed pixel intensity value is based upon a modulated derivative value.
9. The method of Claim 6 further comprising displaying the video signal on the display.
10. The method of Claim 6 wherein the at least one parametric signal comprises at least one of a luma component and a chroma component.
