Horizontal FOV of Microsoft Lifecam Cinema

Title. I can't seem to find this information in the interwebs.

EDIT: Sorry for the confusion, this is NOT the HD-3000. This is a different product.

Re: Horizontal FOV of Microsoft Lifecam Cinema

The Microsoft webpage has a link to the datasheet for this product.

https://www.microsoft.com/accessorie...hspecs-connect

From the datasheet, the diagonal field of view is listed as 68.5 degrees.

Re: Horizontal FOV of Microsoft Lifecam Cinema

Here's an old thread that has some numbers:

https://www.chiefdelphi.com/forums/s...d.php?t=144285

Empirically, my team has found that 53* is closer to correct.

Interesting! Empirically, we found HFOV is about 53 degree too.

That is the wrong webcam. This is the right one: https://www.microsoft.com/accessorie...nema/h5d-00013

Re: Horizontal FOV of Microsoft Lifecam Cinema

That's mostly the difference between horizontal FOV and diagonal FOV. Using 53.0 degrees HFOV and a 16:9 ratio between the HFOV and VFOV and the formula for the angle between two points on a sphere given latitude and longitude, and assuming that rectangle is bisected by the equator, I get 66.0 degrees as the diagonal FOV.

According to the datasheet (copied directly off the page you linked to), the diagonal is 73 degrees.
Edit: from 16:9 ratio, inferred HFOV is 64.4 degrees, VFOW 36.2 degrees.

Thanks. I wasn't sure how to do the calculation for diagonal to horizontal.
