The defect pixel correction (DPC) block is responsible for correcting defective pixels present on the sensor as an artifact of the manufacturing process. The defect pixel detection can either be LUT based or on the fly (OTF – DPC). For LUT based DPC, the defect map is stored in a memory.
Figure 6-66 shows a high level block diagram of the DPC module. The DPC comprises of two different methods of performing the functionality, each of which is highlighted below. The LUT based defect correction mechanism requires the sensor to be calibrated and the defect positioned stored in memory, whereas the Adaptive DPC automatically detects defects and corrects them. If required the LUT DPC and adaptive DPC can be enabled together in sequence.
