It is the chip sized used by many if not most of the portable broadcast size cameras. One definition I found on the internet follows.... "A 2/3-inch CCD such as those found in many professional video cameras has an image area with an 11 mm diagonal. For conventional 4:3 format television, this works out to a picture 8.8 by 6.6 mm. (You'll note that none of these dimensions is very close to 2/3 inch. In fact, pretty much nothing about a 2/3-inch CCD is 2/3 of an inch; a 2/3-inch CCD is simply one that has the same imaging area as a 2/3-inch television camera tube. For what it's worth, those dimensions happen are very close to those of 16 mm movie film.)" A little short of a full frame 35mm I would day!
