Setting the AOI
Except for the scA1300-32 and scA1600-28 cameras, the AOI is set by default to use the full
resolution of the camera’s sensor. For the scA1300-32 cameras, the default resolution is set to 1280
x 960 pixels for mono models, and to 1278 x 958 pixels for color models. For the scA1600-28
cameras, the default resolution is set to 1626 x 1232 pixels for mono models, and to 1624 x 1230
pixels for color models.
You can change the size and the position of the AOI by changing the value of the camera’s X Offset,
Y Offset, Width, and Height parameters.
The value of the X Offset parameter determines the starting column for the area of interest.
The value of the Y Offset parameter determines the starting row for the area of interest.
The value of the Width parameter determines the width of the area of interest.
The value of the Height parameter determines the height of the area of interest.
When you are setting the camera’s area of interest, you must follow these guidelines:
The sum of the current X Offset setting plus the current Width setting must not exceed the
width of the sensor in the camera model you are using. For example, on the monochrome
version of the scA640-70, the sum of the current X Offset setting plus the current Width setting
must not exceed 659.
The sum of the current Y Offset setting plus the current Height setting must not exceed the
height of the sensor in the camera model you are using. For example, on the monochrome
version of the scA640-70, the sum of the current Y Offset setting plus the current Height setting
must not exceed 494.
On monochrome cameras:
The X Offset, Y Offset, Width, and Height parameters can be set in increments of 1.
On color cameras:
The X Offset, Y Offset, Width, and Height parameters can be set in increments of 2 and they
must be set to an even number. For example, the X Offset parameter can be set to 0, 2, 4, 6, 8,
etc.
Normally, the X Offset, Y Offset, Width, and Height parameter settings refer to the
physical columns and rows in the sensor. But if binning is enabled, these
parameters are set in terms of "virtual" columns and rows. For more information,
see Section 12.6 on page 275.
