active line region

The region of lines actively being stored. Defined by a line start (relative to
the vertical synchronization signal (VSYNC)) and a line count.

active pixel region

The region of pixels actively being stored. Defined by a pixel start [relative
to the horizontal synchronization signal(HSYNC)] and a pixel count.

ADC

Analog-to-digital converter. An electronic device, often an integrated
circuit, that converts an analog voltage to a digital value.

address

Value that identifies a specific location (or series of locations) in memory.

ANSI

American National Standards Institute.

antichrominance filter

Removes the color information from the video signal.

API

Application programming interface.

area

A rectangular portion of an acquisition window or frame that is controlled
and defined by software.

array

Ordered, indexed set of data elements of the same type.

ASIC

Application-Specific Integrated Circuit. A proprietary semiconductor
component designed and manufactured to perform a set of specific
functions for specific customer needs.

aspect ratio

The ratio of a picture or image’s width to its height.

B

b

Bit. One binary digit, either 0 or 1.

B

Byte. Eight related bits of data, an eight-bit binary number. Also denotes
the amount of memory required to store one byte of data.

back porch

The area of the video signal between the rising edge of the horizontal
synchronization signal (HSYNC) and the active video information.

black reference level

The level that represents the darkest an image can get
