Title:
SENSOR APPARATUS AND METHOD FOR NOISE REDUCTION
Document Type and Number:
WIPO Patent Application WO2006017544
Kind Code:
A3
Abstract:
A sensor (102) including an array of sensor elements (104) 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 (102) determines a temperature indicator based on the dark count for the hot sensor elements and calculates the dark count for all sensor elements (104) based on the temperature indicator. Based on the dark count the sensor is able to compensate for dark current.
