1. Arrangement for processing a signal field of sensor signals which originate from the individual sensor elements of a plurality of sensor elements which are regularly spaced in an area and which are each surrounded by six adjacent sensor elements while forming a hexagonal structure, the arrangement receiving the sensor signals having feeding points in an assignment which corresponds to the hexagonal structure of the arrangement of the sensor elements, each feeding point being connected with each of the six adjacent feeding points by way of one switchable resistor respectively which can take two switching conditions in which the current conduction through the respective resistor is either interrupted (switching condition "off") or not interrupted (switching condition "on"), and an analog circuit being assigned to each resistor, to which analog circuit a potential difference is fed above the resistor, and which, while taking into account this potential difference as well as a preselectable switching threshold, causes the change between the switching conditions of the respective switchable resistor, characterized bya differential amplifier which, by means of the comparison between a quantity representing the potential difference and a reference quantity forms a switching quantity (IM0) on the output side,a switching comparator which, on the input side, receives the switching quantity and, if this switching quantity exceeds the preselectable switching threshold, on the output side emits a switching pulse which causes the "off" switching condition,four signal outputs 1, 2, 3, 4 as well as four signal inputs (IM1, IM2, IM3, IM4) which are each connected with a signal input and a signal output of one of the four analog circuits assigned to the four next adjacent switchable resistors, one signal respectively being supplied to the four signal outputs which represents the switching quantity,and a switching stage for forming the reference quantity while taking into account the signals present at the four signal inputs.
