Abstract
Some examples described herein include a noise-reduction circuit for an image sensor. The noise-reduction circuit can include a reference frame generator configured to generate a reference frame based on a set of image frames received from an image sensor during a calibration phase. The noise-reduction circuit can also include a memory coupled to the reference frame generator. The memory can receive the reference frame from the reference frame generator and store the reference frame for subsequent use during a noise-reduction phase. The noise-reduction circuit can further include a processor coupled to the memory. The processor can retrieve the reference frame from the memory and use the reference frame to reduce noise in an image frame received from the image sensor during the noise-reduction phase.
