SPAD-based solid state CMOS image sensors utilising analogue integrators have attained deep sub-electron read noise (DSERN) permitting single photon counting (SPC) imaging. A new method is proposed to determine the read noise in DSERN image sensors by evaluating the peak separation and width (PSW) of single photon peaks in a photon counting histogram (PCH). The technique is used to identify and...
Recent advancements in CMOS image sensor technology are reviewed, including both passive pixel sensors and active pixel sensors. On-chip analog to digital converters and on-chip timing and control circuits permit realization of an electronic camera-on-a-chip.
Photodiode (PD) light sensors, PD arrays and image sensors with a wide spectral response, including ultraviolet light (UV-light) waveband of 200-380 nm, are strongly required in the fields of various spectrophotometric analysis, biological phenomena analysis, environmental assessment and space vision1)~4). For the image sensor development, an improvement of UV-light sensitivity and an improveme...
We describe in this paper the building of a vision sensor able to provide video capture and the associated global motion between two consecutive frames. Our objective is to propose embedded solutions for mobile applications. The global motion considered here is the one typically produced by handheld devices movement, which is required for our purpose of video stabilization. We extract this glob...
