DARK SIGNAL MODELING

摘要

A method of compensating for dark signal in an image signal, the method including generating a dark signal model from a dark signal measurement, the dark signal being a digital signal representing a dark frame captured by an image sensor when shielded from exposure to light; and estimating the dark signal present in an object signal using the dark signal model, the object signal being a digital signal representing an object frame captured by the image sensor when exposed to light.
