Aperture
The opening of the lens that determines the angle through which light travels to come into focus.
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).
Blend region
The area of the image that is to overlap with another image in an edge blend setup. Sometimes called overlapping region.
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). In Component Video signals, brightness is the same as
luminance.
Brightness (optical)
Describes how 'bright' an image that is projected onto a screen appears to an observer.
