Abstract
In an image detection device comprising at least one column arrangement consisting of photo detector elements linearly arranged in a row, an image field will be swung alternately across the photo detector elements in both longitudinal directions of the column arrangement. For time-correct summing and output of the detector signals, the photo detector elements of one column arrangement will be connected with a TDI arrangement. The TDI arrangement features a switch arrangement comprising several switches as well as a memory unit containing several memory cells. By appropriate control of the switch arrangement, its switches will be set such that the detector signals generated in the photo detector elements by one and the same image field pixel will be integrated into one and the same memory cell of the memory unit.
