Abstract: A method for controlling a scanning apparatus for scanning a continuously moved object includes seizing the actual momentary position of the moving object, and controlling the time instant or period in which image information is captured by the scanning devices in dependence of the actual momentary position of the object. The scanning apparatus in which the method is used includes a multiplicity of line scanning devices arranged adjacent to each other in the direction of the movement of the moved object. Each of the line scanning devices has a multiplicity of pixels that are arranged adjacent to each other in a direction across a path along which the object is moved. The pixels of the line scanning devices accumulate charges according to the amount of incident light. A controlling means is provided for transferring the charges accumulated in individual pixels to pixels in the adjacent line scanning device in synchronism with direction of the movement and the speed of the moving object.

Abstract: The present invention provides a driving circuit for driving an electronic device, a method of driving an electronic device and a corresponding electronic device including such a driving circuit. The inventive driving circuit is adapted to generate a first and a second clock signal in a push-pull mode. In one embodiment first and second clock signals are generated by respective driver modules and are subject to a push-pull mode coupling provided by a coupling module. Moreover, embodiments of the inventive driving circuit include inductive elements that form a resonant circuit with the internal capacitance of the charge coupled device. The resonant frequency of the resonance circuit substantially equals the frequency of the clock signals, thus effectively allowing for reduction of power consumption of the driving circuit.

Abstract: In a circuit arrangement for regenerating the black level of video signals during A/D conversion, in which a deviation of the black level of the digital video signals from a predetermined value influences the black level of the analog video signals, the scanning values obtained during the A/D conversion of the black level of the analog video signals are compared with the predetermined value. A ramp signal for tendency-compensating the deviations is superimposed on the analog video signals.

Abstract: In a circuit arrangement for regenerating the black level of video signals during their A/D conversion, in which a deviation of the black level of the digital video signals from a predetermined value influences the black level of the analog video signals, the scanning values obtained during A/D conversion of the black level of the analog video signals are compared with the predetermined value. A square-wave signal tendency-compensating the deviations is superimposed on the analog video signals.
