Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
I Need iPhone 4 Camera Specifications - Field of View / Vertical-Horizontal Angle
Does someone know the field of view values for the new iPhone4 camera? I'm doing some AR app's, and I want to know the horizontal and vertical angle of the rear camera.
Note that the aspect ratio of the camera CCD is ~1.33, while the iPhone screen has an aspect ratio of 1.5. So if you maximize your camera image without cropping, you would not completely fill the vertical range of the iPhone screen. In the iPhone camera app, the remaining open space is simply filled by the camera status bar.

Focal length = 3.85mm
CCD Chip Size = 4.54 x 3.39 mm^2
So the FOV angles are 2*ATAN(4.54/2/3.85) and 2*ATAN(3.39/2/3.85). => 61 degrees and 47.5 degrees.
For the iPhone 2, 3g and 3gs (from http://ideenecke.blogspot.com/2009/04/iphone-camera.html):
Focal length = 3.85mm
CCD Chip Size = 3.56 x 2.68mm^2
=> FOV angles: 49.6 and 38.4 degrees
