A camera system comprises at least one imager unit for recording image data and converting said image data into a digital image signal and a video processing unit operatively connected to said at least one imager unit for receiving said digital image signal from said at least one imager unit and for generating a corrected video output signal. The video processing unit comprises a dead pixel correction unit and a subsequent non-uniform offset error correction unit. The dead pixel correction unit is configured for correcting the signal of confirmed dead pixels, which are referenced in a map of confirmed dead pixels associated to the dead pixel correction unit. The non-uniform offset error correction unit is configured for correcting readout amplifier non- uniformity and pixel level non-uniformity in said digital image signal. According to the invention said non-uniform offset error correction unit is further configured for new dead pixel detection simultaneously to said pixel level non-uniformity correction. |
