Patent ID: 7221396

Claim:
A digital camera having a CMOS image sensor ( 2 ) with a plurality of pixels each storing within an exposure time (B) a brightness-dependent charge which is outputted as a pixel signal under the control of a control device ( 8 ), and a correction device ( 6 , 10 ) which, after a pixel RESET of the image sensor, forms the difference from first and second sampled values detected toward the onset and end of the exposure time for the pixel, and outputs the second sampled value reduced by the first sampled value as a wanted signal, wherein the control device ( 8 ) delays the sampling for the first sampled value by a predetermined delay time (D) after RESET, wherein a comparator device compares the second sampled value or the first sampled value with a threshold value (Th), and wherein, if the threshold value is exceeded, the first sampled value, preferably multiplied by a scaling factor, is outputted as the wanted signal.
