Abstract: There is produced for each location of an image sensor, such as an X, Y addressed photodiode array or a self-scanned charge transfer array, a signal indicative of the dark current amplitude at that location. During operation of the sensor, when a location producing excessive dark current is read out, rather than using the signal stored at that location, there is instead substituted a signal level which is the average of that stored in adjacent locations of the sensor.
