چکیده
1. Introduction CMOS image sensors have received much attention over the last decade, offering the promise of ultra low power and camera-on-chip integration in standard fabrication processes. This year over 30 million such sensors have been shipped with estimated annual growth rate of over 40%. Most CMOS image sensors shipped today are application-specific (e.g., optical mouse) or used in low-end applications (e.g., PC-cameras, toys). They are fabricated in older CMOS technologies (0.35µm and above) and as a result have very limited integration. With few exceptions [1], these sensors have significantly lower performance than CCDs.
