Max Segment AOI Pixels with Horizontal Binning
If you have horizontal binning enabled (see Section 3.8 on page 59 ), calculating the Max Segment
AOI Pixels is done a bit differently. With horizontal binning enabled, the resolution of the sensor, the
segment size, the AOI Starting Pixel, and the AOI Length are all based on "binned" pixels. For
example, with horizontal binning enabled on a camera that has 2048 physical pixels in each line,
the effective resolution for each line is 1024 "binned" pixels and the number of pixels in the segment
is 1024 "binned" pixels. With horizontal binning enabled on a camera that has 4096 physical pixels
in each line, the effective resolution for each line is 2048 "binned" pixels and the number of pixels
in each segment of a line is 1024 "binned" pixels. And with horizontal binning enabled on a camera
that has 8192 physical pixels in each line, the effective resolution for each line is 4096 "binned"
pixels and the number of pixels in each segment of a line is 1024 "binned" pixels.
When you are setting up the area of interest on a camera with only one segment in each line and
you have horizontal binning enabled, the Max Seg AOI Pixels is simply equal to the AOI length
multiplied by 2.
When you are setting up the area of interest on a camera with two or more segments in each line
and you have horizontal binning enabled, you first find the segment that contains the largest number
of binned pixels and then you multiply the number of binned pixels in that segment by 2.
Here is an example:
„
Suppose that you are using a camera with 4096 physical pixels in each line and that horizontal
binning is enabled. In this situation, the effective resolution is 2048 and the effective pixels per
segment is 1024.
Assume that the AOI starting pixel is set for 929 and the length is set for 128. With these
settings, the AOI falls across the two sensor segments as shown in Figure 34. Segment 1
includes 96 of the binned pixels in the AOI and segment 2 includes 32 of the binned pixels in
the AOI. The Max Seg AOI Pixels in this situation would be 192 (segment 1 contains the largest
part of the AOI, the number of binned AOI pixels in segment 1 is 96, and 2 x 96 = 192).
