1080p
An
HDTV
resolution
which corresponds to 1920 x 1080 pixels (a widescreen
aspect ratio
of 16:9).
3D active glasses
Wireless battery-powered glasses with LCD shutters. Synchronization information is communicated to the glasses by means of an infrared
(IR) or radio frequency (RF) emitter which is connected to the Sync Out terminal on the projector. IR or RF pulses are transmitted by the
emitter to signal when the left eye and right eye images are being displayed. The glasses incorporate a sensor which detects the emitter’s
signal and synchronises the left and right eye shutters with the projected image.
3D passive glasses
Passive glasses do not require a power source to work. Light with left-hand polarisation can pass through the left lens and light with right-
hand polarisation can pass through the right-hand lens. These glasses are used in conjunction with another device which polarizes the image,
such as a
ZScreen
.
Anamorphic lens
A special lens which, when used with the
TheaterScope aspect ratio
, allows watching 2.35:1 content packed in a 16:9 source.
Aspect ratio
The proportional relationship between the width and the height of the projected image. It is represented by two numbers separated by a colon,
indicating the ratio of image width and height respectively: for example, 16:9 or 2.35:1.
Not to be confused with
resolution
.
Blanking (projection)
The ability to intentionally turn off, that is, set to black, areas around the edges of the projected image. It is sometimes referred to as “curtains”
since it can be used to blank an area of image that literally falls on the curtains at the side of the screen in a movie theater. Usually no image
resizing or geometric correction takes place and the “blanked” part of the image is lost.
Not to be confused with horizontal and vertical
blanking (video signal)
.
