Image sensors are core camera components. With improved technology, especially DPS, performance is getting better and better.
Both CCD and CMOS image sensors are manufactured in silicon foundries; base materials (silicon, silicon oxide and polysilicon) and equipment used are similar. CCD processers and imagers, however, have been optimized specifically for imaging applications for more than three decades. The main difference is architecture and design flexibility of CMOS sensors, especially for applications requiring dedicated signal or image processing that can be integrated on-chip, thus leading to a novel family of smart and compact imagers.
Image System Types
Image sensors are typically categorized into the following three types: CCD, CMOS APS and Pixim's digital-pixel-system technology. CCD sensors are an old technology, re...
