Abstract
A system for processing images typically still images from a slow scan source such as associated with an electron microscope. The analogue source is converted into digital form via an ADC and passes via an adder to a framestore. An output of the framestore is also received by the adder. The capacity of the framestore is sufficiently large to accommodate several hundred summed frames. The image is built up by using all the stored information and all the incoming information. A divider under the control of a frame counter automatically corrects for intensity as the summation of frames progresses, the result being available for monitoring via a digital to analogue converter. Additional mechanisms are disclosed for dealing with other aspects associated with differing frame rates.
