Abstract
Abstract The device has a first image processing stage for generating first image signals and a second image processing stage for generating second image signals and a switch-over device for switching between these first and second image signals. To be able to individually adjust the contrast of the first image signals, at least one variable reference signal, which can be adjusted by a control device as determined by digital control signals, can be supplied to a D/A stage connected at the output end to the first image processing stage (1).
