description The embodiments of the invention here are automated systems and processes for testing a camera device. The processes can detect dark signal non-uniformity (DSNU) within a digital image that has been captured by a solid-state imaging sensor of the camera device under test. Techniques that may be able to detecting localized and global color drifts of various shapes have been described and claimed.
