Temperature Sensors Integrated into a CMOS Image Sensor [PDF]
Proceedings of Eurosensors 2017, Paris, France, 3–6 September 2017, 2017 In this work, a novel approach is presented for measuring relative temperature variations inside the pixel array of a CMOS image sensor itself. This approach can give important information when compensation for dark (current) fixed pattern noise (FPN) is needed. The test image sensor consists of pixels and temperature sensors pixels (=Tixels). The size

Smart CMOS image sensor for lightning detection and imaging [PDF]
Applied Optics, 2013 We present a CMOS image sensor dedicated to lightning detection and imaging. The detector has been designed to evaluate the potentiality of an on-chip lightning detection solution based on a smart sensor. This evaluation is performed in the frame of the predevelopment phase of the lightning detector that will be implemented in the Meteosat Third ...

CMOS image sensor for spatiotemporal image acquisition [PDF]
Journal of Electronic Imaging, 2006 We present a 64-×64-pixel CMOS image sensor chip that can acquire a 16-gray-level image containing both spatial and temporal information of the moving luminous object under observation. The image can next be processed using any image processing software in order to determine the speed, trajectory, and direction of motion of the moving object.
