Abstract
A circuit arrangement for the transmission of picture details through a video chain emphasizes blurred contours and is connected in series with a section serving for the transmission of video signals separated from the synchronized signals of the video chain. The circuit arrangement contains delay means having a tapping point, an adder, and a frequency-independent level control unit that connects the input of the delay means to the first input of the adder. The frequency-independent level control unit is connected between the tapping point and the second input of the adder, and the output of the delay means is connected to the third input of the adder. The first and third inputs of the adder belong to an operation having a common sign opposite to that of the second input, and its input is formed by the input point of the delay means. The output is formed by the output of the adder.
