1. A camera system, comprising:

  • a camera that includes an image sensor and a filter mask; and

    a control and evaluation device that receives an image signal output by the image sensor, wherein;

    the image sensor includes an array of sensor pixels outputting pixel signals,the filter mask includes an array of filters that are situated in front of the sensor pixels and have different wavelength-selective transmission responses,a portion of the filters includes attenuation filters, andsensor pixels, in front of which in each case one of the attenuation filters is disposed, outputs attenuation pixel signals,the image signal output by the image sensor has a first subsequence of first frames taken with a first exposure time and a second subsequence of second frames taken with a second exposure time,the second exposure time is greater than the first exposure time, andthe control and evaluation device evaluates the attenuation pixel signals of the second subsequence.
