Projector
Projector resolution
The number of distinct pixels that make up the image projected by the device, typically expressed as width by height (e.g., 1920 x 1080).
XGA (1024x768)
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′).
4.8 - 67.2 mm
Focus
Specifies the method used to achieve a sharp image, such as automatic (Auto), manual, or fixed focus.
Auto / Manual
Optical zoom
Indicates the optical zoom capacity, which is the number of times that the picture can be enlarged with the optics of the camera.
14x
Digital zoom
Indicates the digital zoom capacity, the number of times that the picture is enlarged thanks to digital technology.
3x
Lens focal range
A cylindrical piece of glass or plastic that receives and focuses light to form an image. Most cameras list an f-number and focal length for each lens. F-Number: Indicates the size of the lens opening (aperture). Focal Length: The distance between the image sensor and the optical center of the lens. Lens Adapter: Allows photographers to use special lens attachments (Macro, Zoom, Filters, etc.) on certain cameras.
F1.5 - F2.1
Image sensor
Optical sensor size
Optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. They are used in many industrial and consumer applications e.g. lamps that turn on automatically in response to darkness. Optical sensors come in many sizes.
25.4 / 3 mm (1 / 3")
Sensor type
A sensor is a convertor than measures a physical quality (light, temperature etc.) and displays this electronically on a device.
CCD
Optical sensor resolution
The sensitivity of the optical sensor, measured in dots per inch (e.g. 16000 DPI), which determines how many pixels the sensor captures per inch of movement or surface area.
850000 pixels
Video
Frame rate
The number of individual images processed or displayed every second, measured in frames per second (fps).
20 fps
Ports & interfaces
Interface
Interface ports to connect pieces of equipment. USB (Universal Serial Bus) has become the most popular wired interface to connect peripherals. USB 2.0 supports speeds up to 480 Mbit/s (USB 1: 12 Mbit/s). The interface FireWire is also known as the IEEE 1394 standard. Enhanced IDE (EIDE)is sometimes referred to as Fast ATA, Fast IDE or ATA-2.
USB 2.0
I/O ports
An interface on a device to which you can connect another device.
VGA USB RS-232C DVI
Technical details
Image freeze
The image taken by a camera is frozen, so that there is no blurring if the subject(s) of the photo are moving.
Image rotation angles
The available angles at which the projected image can be rotated, measured in °.
270°
Technical details
Image save
Indicates whether the device has the capability to save images to internal or external storage.
Image recall
Indicates whether the device has the ability to store and retrieve previously displayed images.
Image divide
Indicates whether the device can split the image into two or more separate sections.
Weight & dimensions
