e2v on CCD vs CMOS Sensors

AZO Materials publishes Teledyne e2v article "The Development of CMOS Image Sensors" with a table comparing CCD and CMOS sensors. Although I do not agree with some of the statements in the table, here it is:

Characteristic	CCD	CMOS
Signal from pixel	Electron packet	Voltage
Signal from chip	Analog Voltage	Bits (digital)
Readout noise	low	Lower at equivalent frame rate
Fill factor	High	Moderate or low
Photo-Response	Moderate to high	Moderate to high
Sensitivity	High	Higher
Dynamic Range	High	Moderate to high
Uniformity	High	Slightly Lower
Power consumption	Moderate to high	Low to moderate
Shuttering	Fast, efficient	Fast, efficient
Speed	Moderate to High	Higher
Windowing	Limited	Multiple
Anti-blooming	High to none	High, always
Image Artefact	Smearing, charge transfer inefficiency	FPN, Motion (ERS), PLS
Biasing and Clocking	Multiple, higher voltage	Single, low-voltage
System Complexity	High	Low
Sensor Complexity	Low	High
Relative R&D cost	Lower	Lower or Higher depending on series

Photonics Spectra on Emerging Image Sensor Applications

Photonics Spectra publishes an article " Emerging Applications Drive Image Sensor Innovations " Hank Hogan. Few quotes: " Vendors are responding by increasing sensor spectral range, integrating new capabilities into devices, and adding features such as 3D imaging. The result can be rapid growth in sensors, even in areas that are relatively stable. For instance, the worldwide market for cars is expanding at a relatively modest pace, according to Geoff Ballew, senior director of marketing in the automotive sensing division of chipmaker ON Semiconductor Corp. of Phoenix. However, tepid growth is not the case for the automotive imaging solutions. “The number of sensors consumed and attached to those cars is growing wildly,” he said. “The image sensor chip business is growing in excess of 15 to 20 percent a year. The reason for that is cameras increasingly are adding new functionality to cars.” Automotive sensors are expected to work from -40 to 125 °C. That interacts with th...

Samsung Expects 10% of Smartphones to Have Triple Camera Next Year

SeekingAlpha : Samsung reports an increase in image sensor sales in Q2 2018 and a strong forecast for both its own image sensor and also the image sensors manufactured at Samsung foundry. Regarding the triple camera trends, Samsung says: " First of all, regarding the triple camera, the triple camera offers various advantages, such as optical zoom or ultra-wide angle, also extreme low-light imaging. And that's why we're expecting more and more handsets to adopt triple cameras not only in 2018 but next year as well. But by next year, about 10% of handsets are expected to have triple cameras. And triple camera adoption will continue to grow even after that point. Given this market outlook, actually, we've already completed quite a wide range of sensor line-up that can support the key features, such as optical zoom, ultra-wide viewing angle, bokeh and video support so that we're able to supply image sensors upon demand by customers. At the same time, we will continue t...
