GENERATING AN IMAGE PRESEGMENTED INTO REGIONS OF INTEREST AND REGIONS OF NO INTEREST

A camera system (10) is provided for generating an image presegmented into regions (106a-b) of interest and of no interest, having an evaluation unit (20) which is designed to divide the raw image into part regions (106a-b) to calculate a contrast value for each part region (106a-b) and to decide with reference to the contrast value whether the respective part region (106a-b) is a region of interest (106a) or a region of no interest (106b). In this respect, the evaluation unit (20) has a preprocessing unit (22) which is implemented on an FPGA, which respectively accesses the pixels of a part region (106a-b) and generates summed values (a), b) for the respective part region (106a-b) and has a structure recognition unit (24) which calculates the contrast value of the part region (106a-b) from its summed values (a, b) without accessing pixels of the part region (106a-b).
