DRAFT
To use the entire CCD array in the
A102
fc
color cameras, set the value for Left to 0, the value for
Top to 0, the value for Width to 1388 and the value for Height to 1038.
3.6.1 Changing AOI Parameters “On-the-Fly”
Making AOI parameter changes “on-the-fly” means making the parameter changes while the
camera is capturing images continuously. On-the-fly changes are only allowed for the parameters
that determine the position of the AOI, i.e., the parameters for top and left. Changes to the AOI
size are not allowed on-the-fly.
The camera’s response to an on-the-fly change in the AOI position will vary depending on the way
that you are operating the camera:
• If the exposure time is
≥
100 µs, the changes will take effect on the next trigger after the
changes are received by the camera.
• If the exposure time is < 100 µs and the camera is running in non-overlapped mode
1
, the
changes will take effect on the next trigger after the changes are received by the camera.
• If the exposure time is < 100 µs and the camera is running in overlapped mode
2
, when the
changes are received by the camera, the camera will delay the triggering of the next image
until transmission of the current image is complete. When transmission of the current image
is complete, the camera will change the AOI position, will trigger the next image, and will
resume running in overlapped mode.
1
The term “non-overlapped” mode means that image capture is triggered in the following manner:
the camera captures (exposes) an image and completely transmits that image out of the camera
before the next image capture is triggered. In other words, exposure and transmission of image
N are both completed before exposure of image N+1 begins.
2
The term “overlapped” mode means that image capture is triggered in the following manner: the
camera captures (exposes) an image and while this image is being transmitted out of the
camera, capture of the next image is triggered. In other words, capture of image N+1 begins
while transmission of image N is still in progress.
L
The sum of the setting for Left plus the setting for Width must not exceed 1392 for
A102
f
monochrome cameras or 1388 for
A102
fc
color cameras.
The sum of the setting for Top plus the setting for Height must not exceed 1040 for
A102
f
monochrome cameras or 1038 for
A102
fc
color cameras.
When you are setting the AOI on an
A102
fc
color camera:
• The setting for Width must be divisible by 2.
• The setting for Height must be divisible by 2.
• The setting for Left must be zero or be divisible by 2.
• The setting for Top must be zero or be divisible by 2.
