- Abstract
- Analog-to-digital (A/D) converters that can be clocked at video rates and that have a logarithmic transfer characteristic between the input and output are now available. Video signal processing using this transfer curve can more closely match the performance of the visual system than normal signal processing. This reduces the visibility of contouring when signals are digitized. It also facilitates the production of color signals that are independent of luminance, thus reducing many of the artifacts in saturated colors. Comparisons are shown on real images between standard processing and improvements that can be achieved by using digital processing of logarithmic signals.
