Recent advances in deep submicron CMOS technologies and improved pixel designs have enabled CMOS-based imagers to surpass charge-coupled devices (CCD) imaging technology for mainstream applications. The parallel outputs that CMOS imagers can offer, in addition to complete camera-on-a-chip solutions due to being fabricated in standard CMOS technologies, result in compelling advantages in speed a...
متن کاملApplications of High Precision Imaging Polarimetry
We propose the use of imaging polarimetry for general photography, which is a relatively young technique allowing the determination of polarized components of the light coming from extended objects or scenes. In this paper high resolution and accurate methods are introduced to determine the two linearly polarized components (Q,U) of light. The CIE Luv color space is used in this work to visuali...
متن کاملTopics on CMOS Image Sensors
Today there exist several applications where a real visible scene needs to be sampled to electrical signals, e.g., video cameras, digital still cameras, and machine vision systems. Since the 1970’s charge-coupled device (CCD) sensors have primarily been used for this task, but during the last decade CMOS image sensors have become more and more popular. The demand for image sensors has lately gr...
