英文摘要	The utility model relates to an electric control device of extracting real-time floating threshold, which is applied to video image processing and particularly aims at segmenting binarization threshold level under complex background conditions. The electric control device of extracting real-time floating threshold is composed of a gain control circuit, a sampling pulse forming circuit, a row background sampling circuit, a video amplifying part, a shot follow driving part, a background subtracting part, a controllable gain video amplifying part and a driving part for drive, wherein input signals of the video amplifying part are video signals which are outputted in two paths, one path is transmitted to an input terminal of the background subtracting part through the row background sampling circuit and the shot follow driving part and the other path is directly transmitted to the background subtracting part. The video signals subtracted by the background subtracting part are transmitted to the controllable gain video amplifying part, and the output signals of the controllable gain video amplifying part are outputted by the driving part. An output terminal of the sampling pulse forming circuit is connected with an input terminal of the row background sampling circuit. The utility model has good segmenting effect, and can meet the requirement of real-time image process.
