CCD or CMOS Image Sensors for Consumer Digital still Photography ?

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...

Comparative 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...

High-Performance Motion Estimation for Image Sensors with Video Compression

It is important to reduce the time cost of video compression for image sensors in video sensor network. Motion estimation (ME) is the most time-consuming part in video compression. Previous work on ME exploited intra-frame data reuse in a reference frame to improve the time efficiency but neglected inter-frame data reuse. We propose a novel inter-frame data reuse scheme which can exploit both i...

Recent Enhancements to Interline and Electron Multiplying CCD Image Sensors †

This paper describes recent process modifications made to enhance the performance of interline and electron-multiplying charge-coupled-device (EMCCD) image sensors. By use of MeV ion implantation, quantum efficiency in the NIR region of the spectrum was increased by 2×, and image smear was reduced by 6 dB. By reducing the depth of the shallow photodiode (PD) implants, the photodiode-to-vertical...
