CCD and CMOS sensors
The charge-coupled device (CCD) has been developed primarily as a compact image sensor for consumer and industrial markets, but is now also the preeminent visible and ultraviolet wavelength image sensor in many fields of scientific research including space-science and both Earth and planetary remote sensing. Today’s scientific or science-grade CCD will strive to maximise pixel count, focal plan...
متن کاملIntroduction and Comparison of CCD and CMOS Image Sensors
This report provides an introduction of the working principle of both CCD and CMOS imager which are widely used in imagine acquisition. The performance and the cost of both devices and the according systems are compared.
متن کاملComparative Study of CCD & CMOS Sensors for Image Processing
Compression is one of the most demanding of the processing steps. Still, image compression is achieved by removing spatial redundancy, while in video devices, temporal redundancy can be used to further improve the compression performance. Various image compression algorithms and coding schemes have been proposed, such as predictive coding, Discrete Cosine Transform (DCT) based compression algor...
متن کاملNeural Monitoring With CMOS Image Sensors
Implantable image sensors have several biomedical applications due to their miniature size, light weight, and low power consumption achieved through sub-micron standard CMOS (Complementary Metal Oxide Semiconductor) technologies. The main applications are in specific cell labeling, neural activity detection, and biomedical imaging. In this paper the recent research studies on implantable CMOS i...

Albert J. P. THEUWISSEN Philips Semiconductors Image Sensors Prof. Holstl.aan, 4, 5656AA Eindhoven, The Netherlands albert.theuwissen(@philips.com Compared to CCD imagers, CMOS image sensors have some clear advantages : lower power, lower driving voltages, onchip functionality, selective read-out and cost. Despite of these advantages, CCDs still deliver a better image quality, especially for di...
