CCD specs often say something like 1/2.5 inches or 2/3 inches.

What exactly does this mean? The second value would seem to be a dimension that is a fraction of an inch, but then what does the first number mean? .4 inches? If so, why express it like 1/2.5?

Also, I notice that no number is not goven for CMOS imagers. Why is that?

Thanks for your help.

That is the physical size of the imager chip itself. Click the link below to see a graphic depiction of the various sized imagers, both CCD and CMOS, that are used in digicams.
