Sensor Apparatus and Method for Noise Reduction

摘要

A sensor including an array of sensor elements generates an image responsive to electromagnetic radiation exposure. The sensor reads coordinates for predetermined hot sensor elements and calculates a dark count for each hot sensor element. The sensor determines a temperature indicator based on the dark count for the hot sensor elements and calculates the dark count for all sensor elements based on the temperature indicator. Based on the dark count the sensor is able to compensate for dark current.
