Camera Performance and Features
37
Eliminating unwanted image data that is visible in the camera’s field of view reduces the amount of
information the host computer needs to process. This may result in an increase to the maximum
allowable line rate when using 12-bit output data.
The camera can accommodate up to four AOIs. Image data outside the AOIs is discarded. Each AOI
is user selected and its pixel boundaries defined. The camera assembles the individual AOI’s into
one contiguous image line with a width equal to the sum of the individual AOIs. The frame grabber
will need to be adjusted to accommodate the smaller overall image width. As the host computer
defined the size of each individual AOI’s, it will be able to extract and process each individual AOI
from the single larger image.
Steps to Setup Area of Interest
1.
Plan your AOI's.
2.
Stop acquisition.
3.
Set the number of AOI's.
4.
Select the first AOI and set the offset and width.
5.
If the other AOI's are large you may need to select them first and reduce their widths.
6.
Repeat for each AOI in turn.
7.
Start acquisition.
The Rules for Setting Areas of Interest
The rules are dictated by how image data is organized for transmission over the available
CLHS data lanes.
The camera / XML will enforce these rules, truncating entered values where necessary.
1.
Acquisition must be stopped to change the AOI configuration.
2.
1-4 AOI's can be selected.
3.
Minimum width is 96 pixels per AOI.
a.
Minimum total of all AOI widths summed together must be at least 1,024.
4.
Maximum width of all AOI widths summed together must be no more than = 16,384.
a.
There can be maximum 8k bytes per CLHS lane.
5.
AOI width step size is 32 pixels.
6.
The offset of each AOI may be 0 to (16,384 – 96 = 16,288).
a.
Therefore overlapping AOI's are allowed.
7.
Offset and width for individual AOI's will "push" one another.
a.
E.g. if AOI has offset 0, width 16,384, and the offset is changed to 4096, then the
width will be "pushed" to 12,288.
b.
AOI's only affect one another by limiting the maximum width.
8.
AOI's are concatenated together in numerical order and sent to the frame grabber starting
at column zero. If the AOI count is reduced to less than the current AOI count, the AOI
selector will be changed to the largest of the new AOI count available.
Customized Linearity Response (LUT)
See the section Camera Control Category in Appendix A for GenICam features associated with this
section and how to use them
Related Features: lutMode, lutType, gammaCorrection
Note: these features may only be useful in applications that use the frame grabber’s Mono Image
Buffer Format. (See also the Pixel Format section.)
