Abstract:
1. An apparatus, comprising: pixel defect logic configured to retrieve pixel repair information that comprises locations of defective photo sensors in an array of photo sensors; pixel replication logic configured to repair defective pixels generated by the array of photo sensors by identifying the defective pixels based on the locations of defective photo sensors where the defective pixels are repaired in a stream of image pixels based, at least in part, on the pixel repair information comprising filtering information; and point defect logic configured to identify a point defect pixel in the stream of image pixels after the pixel repair information is applied, wherein a point defect pixel is a pixel in the stream of image pixels that is not repairable by the pixel replication logic using the pixel repair information; and wherein the point defect logic is configured to adjust the point defect pixel by applying a two-dimensional filter based, at least in part, on a two dimensional array of values from pixels adjacent to the point defect pixel.
