摘要
An image processing system subtracts dark noise out of images based on a dark noise scale factor. The image processing system includes an image sensor for capturing a current image and producing current image data representing the current image. The current image data includes both a dark noise signal and an image signal. The dark noise scale factor for the current image is estimated from the current image data and reference image data representing a reference dark noise signal. The reference dark noise signal is scaled by the dark noise scale factor to produce a scaled dark noise signal from which the current image data is subtracted to produce the image signal.
