Global shutter imagers for industrial applications
SPIE Proceedings, 2014Global shutter image sensors offer significant advantages over rolling shutter imagers but their implementation needs careful consideration. Each pixel needs a storage element on which the signal is stored after the exposure period. To cope with low read noise requirements, it is essential that the pixel can still perform correlated double sampling or ...

Global Shutter CMOS Image Sensor With Wide Dynamic Range
IEEE Transactions on Circuits and Systems II: Express Briefs, 2007A novel concept for global shutter CMOS image sensors with wide dynamic range (WDR) implementation is presented. The proposed imager is based on the multisampling WDR approach and it allows an efficient global shutter pixel implementation achieving small pixel size and high fill factor. The proposed imager provides wide DR by applying adaptive exposure

A new 9T global shutter pixel with CDS technique
SPIE Proceedings, 2015Benefiting from motion blur free, Global shutter pixel is very widely used in the design of CMOS image sensors for high speed applications such as motion vision, scientifically inspection, etc. In global shutter sensors, all pixel signal information needs to be stored in the pixel first and then waiting for readout.

An Autofocus Sensor With Global Shutter Using Offset-Free Frame Memory
IEEE Transactions on Circuits and Systems II: Express Briefs, 2010An autofocus (AF) sensor with global shutters using offset-free frame memory is presented. A cross-shaped AF sensor array has left and right horizontal arrays and top and bottom vertical arrays. AF is achieved by calculating the phase difference from the digital code of the light illumination difference between the left and right (or top and bottom ...

Modeling of Parasitic Light Sensitivity in Global Shutter CMOS Image Sensors
2019 16th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD), 2019This paper aims to model Parasitic Light Sensitivity (PLS) in Global Shutter CMOS Image Sensors (GS-CIS) through separation of the optical problem from the carriers motion one, reducing required simulation time. The optical problem is solved thanks to Finite-Differences Time-Domain (FDTD) simulations. Solution to the carriers motion problem is shown in

Handling rolling shutter effects on semi-global matching in automotive scenarios
2017 IEEE Intelligent Vehicles Symposium (IV), 2017Video sensors based on CMOS technology represent the vast majority of the adopted solutions for image acquisition systems equipped in unmanned vehicles and Advanced Driver Assistance Systems. These sensors typically employ a rolling shutter readout scheme, which causes image distortion in case of motion.
