ASI Output:
The Encoder does not support all the camera resolutions. If you set a resolution not supported by the
encoder, the encoder will stop.
The following formats are supported:
1080i59.94
1080i50
1080p24
1080p23.98
720p59.94
720p50
Defective Pixel Correction (DPC):
To enable the DPC properly, the following steps have to be executed:
o
Switch manually to a 1080p resolution (1080p25 recommended).
o
Put the lens cap on the objective lens.
o
Execute: $DEFECT=0100#
o
The positions of the defective pixels are saved in the FRAM and are available in all
1080p/i and 720p resolutions, even after camera reboot.
o
The Defective Pixel Correction is automatically switched on ($DPC___=0001#).
o
If the return value of the DEFECT command is FFFF, choose a greater value (i.e.
$DEFECT=0180#).
o
The value used by the DEFECT command is the threshold where pixels are marked
as defective.
RAW data output:
The camera features a RAW data output with the following specifications:
o
All in the camera supported 1080p and 720p standards are able to output RAW data.
o
The leftmost pixel in the first line of the active video field is a red pixel.
o
For one RAW data pixel value the 4:2:2 Y and Cb values are used (Y and Cr
accordingly).
o
Use the following equation to calculate the RAW data value for one pixel (Cr
accordingly):
value = (Y-64)*8+(Cb-512)
Inter camera communication (ICC):
Using the inter camera communication (ICC) always requires two cameras connected via a special
communication cable. The first camera has to be configured as Master the second camera has to be
configured as Slave.
To set up a Master/Slave configuration follow these steps:
o
Set both cameras in normal mode ($sync__=0000#)
o
Connect the cameras using the inter camera connection cable
o
Switch camera 1 to master mode ($sync__=0001#)
o
Switch camera 2 to slave mode ($sync__=0002#)
o
The cameras are now in sync.
o
Switch camera 2 to normal mode ($sync__=0000#)
o
Switch camera 1 to normal mode ($sync__=0000#)
o
Power down the camera system
If the slave camera loose the connection to the master camera, the slave camera will immediately stop
operation. The system will resume operation after reconnecting the master and the slave camera
using the communication cable. To reset a slave camera when no master camera is available or
connected, restart the slave camera and wait 10 seconds after the status LED turns blue. The camera
will reset the internal settings memory. After a reboot the camera will start with default settings (normal
mode).
