Zusammenfassung:	This is a method of working film scanning equipment using a light spot in order to produce a video signal that represents a picture on part of a transparent film (10). A focussing curve is designed to control the size of the light spot. The form of the curve is selected so that it allows the spot to increase during at least a part of the scanning process in order to defocus on at least a part of the picture.
