Claim One:
1. A camera system ( 10 ) for generating an image presegmented into regions ( 106 a - b ) of interest and of no interest, having an image sensor ( 18 ) for taking a raw image resolved into pixels and having an evaluation unit ( 20 ) which is designed to divide the raw image into part regions ( 106 a - b ), to calculate a contrast value for each part region ( 106 a - b ) and to decide with reference to the contrast value whether the respective part region ( 106 a - b ) is a region of interest ( 106 a ) or a region of no interest ( 106 b ), wherein the evaluation unit ( 20 ) has a preprocessing unit ( 22 ) which is implemented on an FPGA, which respectively accesses the pixels of a part region ( 106 a - b ) and which generates summed values (a, b) therefrom for the respective part region ( 106 a - b ), and has a structure recognition unit ( 24 ) which calculates the contrast value of the part region ( 106 a - b ) from its summed values (a, b) without making use of pixels of the part region ( 106 a - b ).
