"Image sensors are primarily categorized as CCD image sensors (area image sensor), linear image sensors and X-ray image sensors. The linear image sensor segmented is subdivided into CMOS image sensors, NMOS image sensors and InGaAs image sensors. The linear image sensor is the largest segment; accounting for about 84.2% of the U.S. images sensor market in 2011, largely due to CMOS image sensors, which accounts for more than 90% of the linear image sensor market in the same year. The CMOS (Complementary Metal Oxide Semiconductors) image sensors segment dominates the U.S. linear image sensor market with more than 90% share."
"Portable applications accounts for the largest share of the U.S. image sensors applications followed by toys astronomy. ...Mobile handsets are the leading application for CMOS sensors, representing more than 75% of the total CMOS shipments in 2011. The use of CCD technology will shrink from 14% in 2011 to just 1.3% by 2017."
"Image sensor prices have shown a downward trend over the last few years and are expected to have a similar trend over the next few years. The average selling price per unit of overall image sensors in the U.S. stood at USD 3.9 in 2011. Average cost per unit for CMOS image sensors in the same year was USD 3.5 whereas average cost of CCD image sensors was USD 8.3 per unit."
