A signal processing method for eliminating fixed error sources in the video signal of a pyroelectric vidicon comprising the step of adding the signal value at each point of the pyroelectric plate to previous signal values relating to the same point for forming an integrated or mean value for a great number of signal values at each point and then subtracting the fixed error estimate from the signal values in the latest received video signal. This mean value, if differing from zero, is the estimate of the fixed error at the respective point.
