CCD vs. CMOS - who'll be the next winner?

CCD has been fighting with CMOS since last decade. As we know, CCD has almost won the competition. Most of our digital cameras nowadays are using CCD, except large CMOS sensors in some digital SLRs (mostly Canon). In short, CCD has better image quality, but CMOS use less power and has the potential to deliver higher pixels.

Recently, Sony and Canon seem to have a battle of investment in the development of higher quality CMOS sensors for compact digital cameras. Canon is investing NZ$600 million in a new CMOS production factory and Sony is to invest NZ$660 million on CMOS. We'll see in the next few years how the market will change.
