Lens system
Focal length range Measure of how strongly the system converges or diverges light. For an optical system in air, it is the distance over which initially collimated rays are brought to a focus. A system with a shorter focal length has greater optical power than one with a long focal length; that is, it bends the rays more strongly, bringing them to a focus in a shorter distance.For an optical system in air, the effective focal length (f and f′) gives the distance from the front and rear principal planes (H and H′) to the corresponding focal points (F and F′).	16.90 - 21.61 mm
Aperture range (F-F) Aperture range of the device's optics, expressed in f-stops.	2.43 - 2.78
Zoom capability The amount that the camera lens can zoom.
Zoom ratio Measures how much the camera can adjust its focus for distance shots. A 3x zoom ratio changes the camera's focal length by a factor of three, from 35 mm to 105 mm for example.	0.8 - 2.0:1
Throw ratio	1.13-1.47
Offset	132%

Video
Digital signal format system The protocols supported for exchange of digital signal.	HDTV
Full HD Full High Definition (HD) means that a display supports a resolution of 1920 x 1080 pixel, and has a digital TV connection.
3D The device can be used with 3D technology.
Supported graphics resolutions The graphic resolutions that can be displayed by the device. The graphic resolution describes the width and height dimensions of a display, such as a computer monitor, measured in pixels.	640 x 480 (VGA), 1920 x 1080 (HD 1080), 1920 x 1200 (WUXGA)

HDMI ports quantity The number of sockets (ports) for HDMI connections. HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device ("the source device") to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for existing analog video standards.	2
