Everything about Image sensor
Device that converts images into electronic signals
An image sensor or imager is a sensor used for imaging. It converts light into electrical signals, small bursts of current in proportion to the light intensity. The pattern of electrical signals conveys the information in the image. Image sensors are used in electronic imaging devices of both analog and digital types, which include digital cameras, camera modules, camera phones, optical mouse devices, medical imaging equipment, night vision equipment such as thermal imaging devices, radar, sonar, and others. As technology changes, electronic and digital imaging tends to replace chemical and analog imaging. Wikipedia →
