Abstract:
1. A method for controlling a scanning apparatus for scanning a continuously moving object comprising: accumulating charge in a scanning apparatus, wherein the scanning apparatus includes a plurality of line scanning devices arranged adjacent to each other in a direction of a movement of the moving object, wherein each of the line scanning devices has a plurality of pixels that are arranged adjacent to each other in a direction across a path along which the moving object is moving, wherein each pixel of the line scanning devices accumulates a charge representing image information according to an amount of incident light; and transferring, with a controlling means, charge accumulated in each of the plurality of pixels to pixels in the plurality of adjacent line scanning device in synchronism with the direction of the movement and a speed of the moving object, and wherein the object is illuminated by a light source, wherein an actual momentary position of the moving object is seized, and that a time instant or period in which image information is seized by the scanning devices is controlled depending on the actual momentary position of the object; and controlling the light source to produce light pulses comprising an intensity, a beginning and a duration depending on the momentary position of the object; and controlling the beginning and duration of accumulating the charge according to the amount of incident light originating from substantially a same location of the object wherein the beginning and duration of accumulating the charge is controlled depending on the actual momentary position of the scanned object and on the intensity of the light source.
