Abstract : Consideration is shown of an approach to light sensitivity criteria from the stnadpoint of the selection of an exposure which makes it possible to obtain the maximum number of fine details on an aerial photo. A number of methods of programmed and automatic exposure control are considered, and estimates are made of their errors. Among the methods considered are a method of control according to integral brightness, a method of control according to minimum brightness, an integral method involving the selection of a video brightness signal according to the signal level, and an integral method involving the selection of a video brightness signal according to the level of the brightness coefficient.
