Example implementations relate to PRNU suppression. For example, PRNU suppression may include performing a calibration surface PRNU characterization using a scanning system, performing a document-based PRNU characterization using the scanning system, and determining a correction function for PRNU suppression ...
The Photo-response Non-uniformity (PRNU) is a representation of the uniformity of a camera’s response to light, important in some high-light applications. When light is detected by a camera, the number of photo-electrons captured by each pixel during an exposure is measured, and reported to...

Photo response uniformity of the hybrid device Ideally, the pixel output voltage under a given measurement condition should be uniform across the pixel array. However, various factors such as variation in the threshold voltage (Vtn) of pixel level reset transistors, the difference in the photorespon...
