The total number of pixels between two horizontal synchronization signals.
The pixel count determines the frequency of the pixel clock.
A property of an event or system in which data is processed as it is acquired
instead of being accumulated and processed at a later time.
The smallest signal increment that can be detected by a measurement
system. Resolution can be expressed in bits, in proportions, or in percent of
full scale. For example, a system has 12-bit resolution, one part in 4,096
resolution, and 0.0244 percent of full scale.
Color encoding scheme using red, green, and blue (RGB) color information
where each pixel in the color image is encoded using 32 bits: 8 bits for red,
8 bits for green, 8 bits for blue, and 8 bits for the alpha value (unused).
Region of interest. A hardware-programmable rectangular portion of the
acquisition window.
The U.S. standard used for black-and-white television.
Referenced single-ended. All measurements are made with respect to
a common reference measurement system or a ground. Also called a
grounded measurement system.
The amount of color pigment present. The lower the saturation, the more
white is present in the color. Pink is a red with low saturation.
A type of DMA that allows the DMA controller to reconfigure on-the-fly.
Synchronous dynamic RAM.
The rate, measured in bytes/s, at which data is moved from source
to destination after software initialization and set up operations.
The maximum rate at which the hardware can operate.
Any event that causes or starts some form of data capture.
