Abstract
The invention pertains to a method for operating an image-processing device, in which an image signal is digitally transmitted between a transmitter and at least one receiver, and in which the image signal comprises a timed sequence of images. An alternating signal which alternates at a signal alternation frequency is superimposed on the image content of the images before they are transmitted, and the signal alternation frequency is greater than or equal to the perception frequency resolvable by the human eye. The invention also pertains to an image-processing device.
