A quote from Mats Wernersson's interview:
Q: The megapixel race seems to be over, as consumers are becoming more savvy about the quality of the images their devices capture - how does this affect you and how do you react to these needs?
A: It is a relief that we don't have to hunt for a larger number of pixels for every new generation of phones. But there is still some market pressure for high numbers. We could make a better balanced system with somewhat better perceived image quality if we could pick the megapixel number purely from a technical and image quality point of view.
Few quotes from Gennadiy Agranov's interview:
"...there is the market for sports cameras that consumers can attach to bicycles, helmets, surfboards, skis, cars, motorcycles etc. to capture exciting video and images of their personal sporting adventures. Aptina has a strong position in this market, with what we believe is well over 70% market share, and we expect to secure this position through advances in our high-speed HD video enabled sensor offerings.
...Manufactures of sensors for the mobile market are passing the gate of 1.4 micron pixel node and working on 1.1micron pixels and smaller. The automotive market is moving from 5-6 micron pixels to 3-4 micron pixels. Sensors for the high-end digital camera market are targeting smaller pixels in the 2um - 4um range.
...It is interesting while the world economy and the semiconductor industry are expected to grow in the low single digits of percentage in the coming years, we see the narrower semiconductor segment of image sensors as growing in excess of 15% year-over-year going forward."
