Sensor size: 3.67 x 2.74 mm (1/4 "format)
Pixel Count: 2592 x 1944
Pixel Size: 1.4 x 1.4 um
Lens: f = 3.6 mm, f / 2.9
Angle of View: 54 x 41 degrees
Field of View: 2.0 x 1.33 m at 2 m
Full-frame SLR lens equivalent: 35 mm
Fixed Focus: 1 m to infinity
Video: 1080p at 30 fps with codec H.264 (AVC)
Up to 90 fps Video at VGA

Because the focal length of the lens is roughly the same as as the width of the sensor, it is easy to remember the field of view: at x meters away, you can see about x meters horizontally, assuming 4x3 stills mode. Horizontal field of view in 1080p video mode is 75% of that (75% H x 55% V sensor crop for 1: 1 pixels at 1920x1080).
