Setting the Camera’s CCD Shift Direction
Purpose:
When in TDI Mode, selects the forward or reverse CCD shift direction or external
direction control. This accommodates object direction change on a web and allows you to
mount the camera “upside down”.
In Area Mode, selects the vertical readout direction. This allows you to mirror the image
vertically or mount the camera “upside down”.
Syntax:
scd i
Syntax Elements:
i
Readout direction. Allowable values are:
0 =
Forward CCD shift direction.
1 =
Reverse CCD shift direction.
2 =
Externally controlled direction control via Camera Link control CC3 (CC3=1
forward, CC3=0 reverse). Available only in TDI Mode.
Notes:
•
The following user settings are stored separately for forward and reverse direction;
digital gain, system gain, background subtract, digital gain, background addition
and pixel coefficients. These settings are automatically loaded when you switch
direction. All other settings are common to both directions.
•
See the following figures for an illustration of CCD shift direction in relation to
object movement.
