Appendix D: Glossary
Bit Depth/Bit Window Selection
Enables users to select the bit-depth of data output from the camera.
All internal data is 12 bits per image.
When bit depths less than 12 bits are selected, the least significant bit can be
specified in order to select which of the 12 available bits is output, creating a Bit
Window.
Brightness (Offset)
Controls the black level or offset of the image by specifying a digital number to
be added to all image pixel data.
This value can be written to and read from the camera.
Camera Settings Read/Write
Allows the camera to save its current operating parameters to internal,
non-volatile memory within the Camera Controller.
A set number is used as an identifier for the record.
The record of saved operating parameters can then be applied to the camera.
Multiple sets of camera parameters can be stored and retrieved.
Gain
Controls the gain applied at the CCD. Values are specified in dB.
The value can be written to or read from the camera.
Gain values can range from 0 dB to 34 dB with 1024 levels (10 bits).
Gamma
Defines a relationship between the incoming light level and the output digital
number
Specifying a gamma value is useful to stretch the dark areas of an image making
the information better suited for viewing with the eye.
Integration Time
The electronic integration period of the camera. It is identified as shutter under
the IIDC protocol.
Values are specified in milliseconds.
The integration time value can be written to or read from the camera.
Strobe Output (Trigger-Out)
Trigger signal output from the controller that can be used to control strobed
illumination sources or other synchronous events.
Strobe polarity can be set as either negative or positive.
