ABSTRACT:
The invention relates to a method of executing image processing operations such as object recognition or linear
on-linear filtration on a two-dimensional image. This is performed with light-sensitive sensor elements (4) executed in two-dimensional matrix form. The sensor elements (4) are so arranged as to produce an output signal corresponding to the light intensity. The output signal of each sensor element is compared with a monotone increasing or reducing reference value. The extent to which the output signal from the sensor element is greater than or less than the reference value is continuously monitored for each sensor element. An arrangement for the execution of this method comprises a number of sensor elements (4) arranged on a substrate. Each of these has allocated to it on the substrate a comparator (5) so arranged as to compare the output signal of the sensor element with a pre-adjustable reference value and a sub-processor. Each sub-processor (8) is so arranged as to identify the occurrence of combinations of sensor elements (4) for which the output signal has exceeded or has not exceeded the aforementioned reference value.
