Abstract
A device for correcting a defect pixel value of a CMOS image sensor unit is proposed, the image sensor unit comprising at least a first and a second pixel array. The image sensor unit is arranged to project the same image onto each pixel array. The correcting device comprises at least a first and a second input channel for receiving pixel values of the first and the second pixel array, respectively. The processing device is operable to replace the defect pixel value by a corrected pixel value, which is determined from values of neighboring pixels to the defect pixel of the same pixel array. The corrected pixel value is evaluated with respect to values of a corresponding pixel and its neighboring pixels of the second pixel array at the same location as the defect pixel of the first pixel array in respect to the projected image.
