Notes
1080p
An HDTV resolution which corresponds to 1920 x 1080 pixels (a widescreen aspect ratio of 16:9).
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).
Blanking (video signal)
The section of the video signal where there is no active video data.
Not to be confused with blanking (projection).
Brightness (electronic control)
A control which adds a fixed intensity value to every pixel in the display, moving the entire range of displayed intensities up or down, and is
used to set the black point in the image (see Contrast).
