    • 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).
    • 提供一种相机系统(10),用于生成预先分割成感兴趣的区域(106a-b)并且不感兴趣的图像,具有评估单元(20),该评估单元被设计为将原始图像分割成部分区域(106a-b) 计算每个部分区域(106a-b)的对比度值,并且参考对比度值来确定各个区域(106a-b)是否是感兴趣区域(106a)或不感兴趣的区域(106b) 。 在这方面,评估单元(20)具有在FPGA上实现的预处理单元(22),分别对部分区域(106a-b)的像素进行访问,并产生相加值(a),b) 各个部分区域(106a-b),并且具有一个结构识别单元(24),它从其求和值(a,b)中计算部分区域(106a-b)的对比度值,而不访问部分区域(106a- b)。
