"...annual revenues for stand-alone digital cameras have been on the decline since 2007. Worldwide unit shipments of digital still cameras, which peaked in 2011 at 142 million systems, are expected to decline 3% in 2013 to 133 million after falling 4% in 2012.
In 2012, camera phones with 3Mpixel or greater image sensors were outselling stand-alone digital still cameras by a 6:1 ratio.
The lack of digital camera growth has shifted a great deal of the IC industry’s attention in digital imaging from stand-alone photography products to new applications and embedded systems, such as enhanced machine vision for automotive safety and industrial equipment, intelligent video surveillance networks, medical imaging, and small camera modules for smartphones, tablet computers, and other portable devices. The total market value for digital cameras and imaging systems is expected to grow from $55.5 billion in 2012 to $77.8 billion in 2016. In doing so, this market will shift from being heavily dependent upon stand-alone cameras to being more evenly spit across several end-use equipment segments.
...IC Insights forecasts total shipments of digital cameras and embedded imaging systems will reach 6.0 billion units in 2016 compared to 2.5 billion in 2011, which represents a compound annual growth rate (CAGR) of 19.0% in the five-year period."
Digi-Key too published a market analysis, mostly referring to IC Insights:
"CMOS image sensor revenue will end 2012 growing 21 percent to a record $7.1 billion... Total image sensor revenue, including CMOS sensors and CCDs, will total $9.5 billion in 2012."
