All BW-14 Bit cameras support ”Vertical Binning“ (1/2 vertical reso-
lution). In horizontal direction “Decimation” can be used:
The BW camera sends a DVAL signal with 1/2 pixel clock frequency.
When DVAL signal is enabled on the grabber only every second pixel
in horizontal direction is grabbed.
When vertical binning is enabled on the camera and DVAL signal is
enabled on the grabber, the image looks like 2 x binned.
“Decimation Mode” : only evey third line is readout from the sensor
and the DVAL signal from the camera masks out 2 of 3 pixels in hori-
zontal direction 1/3 pixel frequency). (not supported by every sensor)
When DVAL signal is enabled on the grabber only every third pixel in
horizontal direction is grabbed.
The “Bayer” pattern color information is preserved with 1/3 horizontal
and vertical resolution. The frame readout speed increases approx. by
factor 2.5.
NOTICE
To get the full resolution from 14 Bit Cameras the
DVAL signal has to be disabled on the Grabber
