Image data flow and controls order
13 Goldeye Camera Link Register Controls Reference V1.0.0
Image data flow
To develop your application effectively, note the order in which the controls are
processed in Goldeye G/CL cameras.
In the Goldeye G/CL User Guide, the image data flow describes the sequence of
image processing steps inside the camera. The shown functionalities represent
controls or control groups.
Note that, depending on firmware version, not all of the modules and controls
shown in Figure 1 are available.
This behavior includes other controls as well as described in Value changes by
control interdependencies on page 14.
