View Full Version : XL2 CMOS Dimensions?
John Sandel September 15th, 2008, 01:27 PM Anybody know the height & width of the XL2's chip(s)—just one—in millimeters?
I can find the height & width in pixels. I can find the diagonal in millimeters & inches.
I've searched the XL2 manual, this thread, this forum, other fora, Canon's website and the web generally, to no avail.
… anybody?
Jarrod Whaley September 15th, 2008, 02:48 PM Well, for one thing, the chips are CCD's, not CMOS.
As for the height and width: can't you just do a little basic high-school algebra to figure out the dimensions based on the diagonal measurement and the 4:3 AR of the chips?
Just out of curiosity, why do you need to know this anyway?

1. CCDs, yes, thanks. Call them "chips" and we understand each other.
2. No. I was an English major.
3. That's a secret.

This might help...

John Sandel September 15th, 2008, 05:18 PM Thanks, Greg. I remember when Chris posted that. It doesn't give the dimensions I want, which are proving elusive.
Chris Hurd September 15th, 2008, 05:26 PM The width and height of the imaging area only, or the entire face of the chip?
John Sandel September 15th, 2008, 05:37 PM Imaging area, please. I thought you'd pop up.
Chris Hurd September 15th, 2008, 05:42 PM It's *roughly* 4.8mm by 3.6mm. From that you'll have to do some basic math to account for the unused pixel area above and below the 16:9 active portion. Best I can offer here, sorry.
John Sandel September 15th, 2008, 06:48 PM Addition and subtraction I can do. Did you measure it by hand or do you have a reference for that?
Chris Hurd September 15th, 2008, 09:26 PM That's a secret.

Thanks. You guys always come through.
