What is dynamic bad pixel correction

From the static and dynamic distribution of bad pixels, they can be divided into static bad pixels and dynamic bad pixels. From pixel brightness, they can be divided into bright spots and dark spots.

Static Defective Pixel (SDP) is caused by chip defects in image sensor technology. The solution is based on a predetermined static bad pixel table, comparing whether the current coordinates are consistent with certain coordinates in the static bad pixel table. If the coordinates are consistent, it is determined as a bad pixel, then the correction result is calculated and corrected.

Dynamic Defective Pixel (DDP) is related to sensor temperature and gain. When sensor temperature increases or gain value increases, dynamic bad pixels will increase.

The dynamic bad pixel correction function in the software sidebar uses algorithms to determine whether a point is a bad pixel. If it is a bad pixel, correction is performed. The correction can set thresholds and values.
