Experimental Characterization of IdleTones in Second-Order Bandpass ΣΔ Modulators
(2000)
This paper analyses the tonal behaviour of the quantization noise in second-order bandpass ΣΔ modulators. The analysis performed for lowpass modulators is extended to the bandpass case. As a result, closed form expressions ...

On-site forest fire smoke detection by low-power autonomous vision sensor
(2010)
Early detection plays a crucial role to prevent forest fires from spreading. Wireless vision sensor networks deployed throughout high-risk areas can perform fine-grained surveillance and thereby very early detection and ...

Form Factor Improvement of Smart-Pixels for Vision Sensors through 3-D Vertically- Integrated Technologies
(Institute of Electrical and Electronics Engineers, 2014)
While conventional CMOS active pixel sensors embed only the circuitry required for photo-detection, pixel addressing and voltage buffering, smart pixels incorporate also circuitry for data processing, data storage and ...

A 151 dB high dynamic range CMOS image sensor chip architecture with tone mapping compression embedded in-pixel
(Institute of Electrical and Electronics Engineers, 2015)
This paper presents a high dynamic range CMOS image sensor that implements an in-pixel content-aware adaptive global tone mapping algorithm during image capture operation. The histogram of the previous frame of an auxiliary ...
