Description
Off
This options sets the camera to normal operation mode.
GreyHorizontalRamp
If this option is set, the camera sends an image with a horizontal moving gray scale ramp.
The test image includes also a frame counter superimposed in its image (see below).
FrameCounter
If this option is set a frame counter is superimposed into each captured frame or ROI.
The frame counter overlays 4 pixel in the upper left corner of each frame. The counter starts
with 0 on each activation and will start with 0 again if reaching its max. value. The counter
will also be reset to 0 on each acquisition start command.
In 10 bit modes the bits 1..0 in each pixel gets set to 0.
Counter layout:
Pixel
Meaning
0
Frame counter LSB part (counter bits 7..0).
The values of pixel 0 and 1 are used to build a consecutive running16 Bit frame
counter in little-endian notation. If the 16 bit counter overruns it starts with 0
again.
1
Frame counter MSB part (counter bits 15..8)
2
Frame counter active marker.
If the frame counter is active this value is always 0xAA.
3
ROI number.
For cameras with the Multi-ROI feature the frame counter is inserted in each
ROI. This value reflects the number of the ROI the frame counter is superim-
posed starting from 1 for ROI 1. Because a 'set of ROI's' belongs always to one
frame the frame counter is in each ROI the same. For cameras without the Multi-
ROI feature or if just one ROI is defined this value is always 1.

Current test image selector.
Remark:
•
A Link Reset sets the camera to normal operation mode.
•
If the Grey Horizontal Ramp test pattern is selected the frame counter gets activated au-
tomatically too.
•
Acquisition-Stop/Start sets the frame counter to 0.
•
Activating the FrameCounter also reset the counter to 0.
