CMOS Image Sensors Catch Up

Posted April 18, 2007 8:46 AM
Pathfinder Tags: CCD detectors CMOS sensors

In the electronic imaging world, CCD detectors have traditionally offered the highest resolution, but CMOS image sensors, fueled by a mature fabrication infrastructure, offered better price points. It used to be that you had to choose one or the other. No more. The new 8.4 Mpix CMOS image sensor offers CCD-level resolution with 1.4-um pixels and significantly lower power consumption.

More than the resolution it is the speed of image capture + higher sensitivity that matters in photography. I have seen 4 & 5 megapixel ccd cameras giving finer details than the 12 mpxl & higher cameras. Maybe because the exposure time is so short that there is no possibility of shake affecting the image. Pixel size can always be compensated for by a properly designed & matched optics.

I am talking from 1st hand experience of using both amateur level Casio camera and a professional level Canon camera.

The main problems with digital capture is the time it takes the electronics to set up between shots. I have a high end Olympus 8Mp camera and it has image stabilization built in. It works very well. But it takes 3-4 secs to store the image and reset for the next take. Another annoyance is the shutter lag, the time between pushing the button and the image being captured. I still prefer 35mm film.
