CV-A10 CL and CV-A70 CL

6.1.3. CV-A10 CL. Binning

Binning is only on CV-A10 CL.
The binning functions can be used for higher

frame rate or for higher sensitivity. The
drawback is lower resolution.
Vertical binning is done by adding the charge
from pixels in adjacent lines in the
horizontal ccd register.
Horizontal binning is done by adding the
charge from adjacent pixels in the
sample/hold circuit capacitor.

In horizontal binning, the pixel clock will not
change, so the grabber will over sample.
Vertical and horizontal binning can work
together. If same factor is set for horizontal
and vertical binning, and the sample rate is
divided with same factor, the resulting
image will have correct aspect ratio.
Upper right hand schematic shows the

binning principle. Resolution and sensitivity
for all combinations are shown below.

CV-A70 CL is a color camera based on a
CCD sensor with a Bayer RGB color
mosaic.
The color image reconstruction is done
in the host PC frame grabber.
The Color sequence in the video signal

differ from full scanning to partial
scanning. The right hand drawing shows
the color sequence at the image start.
The start line # is shown from LVAL.
The start pixel is # 9 from LVAL. It is
when DVAL rise.

The Bayer color sequence starts with:

GBG for even line numbers.
RGR for odd line numbers.
