e-Phocus develops Photoconductor on Active Pixel (POAP) technology. The technology is based on coating of a CMOS chip with a photoconductive layer.
e-Phocus’ image sensors are claimed to deliver an unprecedented price/performance ratio. It can provide the lowest cost for the required performance. I dont know why the cost would be lower if it still uses CMOS processing, but it's an interesting claim. Up to now I havn't seen an image sensor startup claiming to become the cost leader.
The initial products are targeted to cell phone cameras and high resolution digital cameras (up to 40MP). So far the company is hosted by Trex Enterprises technology incubator.

Samsung Talks about Embedding Image Sensor into LCD Screen
The Korea Times: Kim Sang-Soo, EVP of Samsung LCD Technology Center, talks about large LCD-based e-boards as a big market opportunity:
"E-boards can replace the white boards and beam projectors currently in use, with 100-inch or larger displays.
To jumpstart the e-board market, the industry must secure technology for multi-touch screens and develop an image sensor that can be built into these displays to allow users to write on the displays in a way that is easy to read. We think this market holds great promise as a virtual 'cash cow' if we can provide e-boards with an interactive communications function that allows meetings and conferences to be more widely shared in real-time."

Himax Imaging Startup
The latest image sensor start-up company Himax Imaging is seed-funded by a large LCD driver vendor Himax, Taiwan. Himax Imaging is headquartered in Irvine, CA. Its technical lead, Dr. Sergi Lin, used to work for ESS and Biomorphic, both out of imaging business now. At least he had a chance to learn from their mistakes. Before that he worked for TSMC as a process integration engineer - an ideal experience for modern pixel designer.
Himax Imaging's "pixel-centric design philosophy" is claimed to provide 4x sensitivity over "conventional pixels" (what is conventional? Nobody uses "conventional pixels" these days, listening to the marketing departments). Its first product seems to be based on 1.75um pixel.

Micron Quarterly Conference Call
Yahoo: Micron reports that sales of CMOS image sensors in the Q1 of fiscal 2008 increased approximately 15 percent compared to the previous quarter as a result of a higher level of unit sales.
Seeking Alpha: Micron managed to keep ASP relatively flat as it migrates the business towards higher pixel densities.
Regarding the imaging business spin-off Steve Appletone says:
"With respect to imaging, as I said the last time, we don’t have any plans to change manufacturing the product. We’ve been looking at ways -- really, is there some other partnership that’s a better way to take that product to market after it’s been produced, so to speak, and we’re just still in the middle of trying to work through that and figure out what the best path is."
In terms of product mix, just over half of the unit shipments were 2-megapixel and above, and by definition just under half were at 1-megapixel and below.

VGA Sensors Shortage Eases
Digitimes: Short supply of power amplifiers (PAs) hit the handset industry dampening the handset chip market.
A weaker handset chip market has helped ease the shortage of VGA sensors, but that may not last long, the Digitimes sources said. The shortage of PAs is expected to ease by the end of the year and will rally demand for China's white-box handsets, the sources remarked.

Toshiba Focuses on Tessera OptiML
Tessera licensed its Eyesquad-OptiML focus enhancement technology to Toshiba.
So by now almost all leading sensor makers adopted some form of computational focus technology:
- ST Micro and Magnachip go with DxO Labs
- Omnivision acquired CDM Optics
- Toshiba endorsed Eyesquad-Tessera solution
- Samsung reportedly works with DBlur
Micron seems to be the only large vendor with unknown plans (unknown to me, that is).
