Here used to be a link to the presentations from the recent Intertech-Pira Image Sensors 2009 conference (San Diego Oct. 13-16). A lot of interesting stuff!

On the technical side, Don Scansen shows Chipworks reverse engineering picture of Omnivision BSI packaging scheme:
Another interesting presentation comes from DxO Labs on camera module self calibration. It presents very nice features but no word is said about the price to implement them in silicon - an important omission. Also, Gr/Gb imbalance section excessively downplays the alternative approaches to the problem.
On the marketing side, there is an interesting presentation by Sanyo on digital camera market, product trends and adoption rates. Toshiba presentation mainly talks about the market consolidation trend. The Strategies Unlimited presentation disappointed me a bit, as its many data labels from the charts are removed - looks like a teaser for the paid reports.
