For example, most of the megapixel CMOS imagers on the market are not based on the latest pixel designs. Some chips in the most popular products being sold are two generations old. Secondly, the imagers getting the newest pixel technology are aimed at camcorder or digital camera markets, so they aren't always usable or even available to security camera manufacturers. Sony, for example, won't sell most of their new CMOS imagers to security camera manufacturers, only to consumer electronics companies. What I'm going on is what the pixel designers are telling me. The latest pixel designs in CMOS are equaling the performance of CCD. Even Sony engineers have now said this, and if anyone has a reason to protect CCD, it would be Sony. So, I think 2009 will still have companies selecting some CCD imagers, and maybe even into early 2010, but after that I think it is all in the favor of CMOS. I will add one more important piece to this discussion. CMOS imagers are digital from the chip, so it is easier to process the data, but without the right image processing the low light performance is not as good. Some companies are not including this added noise reduction, which is why their low light performance is over 1 lux. But this kind of high quality noise reduction will become standard by mid next year, and continue to improve. So, it isn't just the imagers, it is also the image processing chips that haven't quite caught up yet. However, it looks like in 2010 this will all shift to advantage CMOS. That's why I'm saying the days of CCD are numbered. I hope that helps. Doug. John,

There are a lot of reasons why some companies are choosing CCD megapixel imagers still, this year.

For example, most of the megapixel CMOS imagers on the market are not based on the latest pixel designs. Some chips in the most popular products being sold are two generations old.

What I’m going on is what the pixel designers are telling me. The latest pixel designs in CMOS are equaling the performance of CCD. Even Sony engineers have now said this, and if anyone has a reason to protect CCD, it would be Sony.

So, I think 2009 will still have companies selecting some CCD imagers, and maybe even into early 2010, but after that I think it is all in the favor of CMOS.

There seems to be a lot of concern about low light megapixel image quality and the potential for CCD to resolve this. What do you think of this? Best, John Hi Doug,

I have talked to a number of megapixel camera manufacturers recently who emphasized that they were moving to CCD chips (most frequently cited was Sony CCD chips). There seems to be a lot of concern about low light megapixel image quality and the potential for CCD to resolve this.

What do you think of this?

Best,
