Abstract

A method of reducing noise in a digitally sampled image is achieved in which an entire frame image is divided into regions which are used to determine the relative noise level of the static image over a period of several frames. The relative noise level is taken as a measurement and is then used by the firmware to make adjustments during the digital sampling process. By using less than the entire frame of the image information the method of reducing noise can be implemented without requiring the presence of a frame buffer.
