(e.g., 8-bits, 15-bits, 24-bits) defines the number of gray levels or colors possible for each
pixel.
RGB
A representation of color using the three primary colors (red, green, blue) as components.
Video signals in RGB format are typically a non-composite video standard. A digital true
color image can be represented by 8-bits per color (24-bits/pixel). Often image data is stored
or transferred in 32-bits/pixel where the upper 8-bits of each pixel are unused.
Scatter Gather
Host system memory allocated for frame buffers is virtually contiguous but physically
scattered throughout all available memory.
Trigger
A mechanism that initiates an action when an event occurs such as synchronizing an image
acquisition to an external event. A trigger generally causes a program routine to be executed
such as the resetting of camera exposure and/or the firing of a strobe light.
