6.2 Area of Interest
The area of interest feature lets you specify a portion of the sensor lines. During operation, only the
pixel information from the specified portion of the lines is read out of the sensor and transmitted from
the camera to the frame grabber.
The size of the area of interest is defined by declaring a starting pixel and a length in pixels. For
example, if you specify the starting pixel as 33 and the length in pixels as 256, the camera will
readout and transmit pixel values for pixels 33 through 288 as shown in Figure 42.
Fig. 42: Area of Interest
If you are operating the camera in single line acquisition mode, the AOI applies to line A. In all other
line acquisition modes, the AOI applies to both line A and line B. For more information about line
acquisition modes, see Chapter 3 on page 39.
When setting the AOI, the following guidelines apply:
The AOI Starting Pixel can be set to 1 and can be increased in increments of 32.
The AOI Length must be a minimum of 256 pixels can be increased in increments of 32.
The AOI Starting Pixel + AOI Length
≤ Number of Pixels in Each Sensor Line + 1.
For example, if you are working with a camera that has 2048 pixels in each sensor line:
The AOI Starting Pixel can be set to 1, 33, 65, 97, etc.
The AOI Length can be set to 256, 288, 320, 352, etc.
The AOI Starting Pixel + AOI Length
≤ 2049.
If you are working with a camera that has 4096 pixels in each sensor line:
The AOI Starting Pixel can be set to 1, 33, 65, 97, etc.
The AOI Length can be set to 256, 288, 320, 352, etc.
The AOI Starting Pixel + AOI Length
≤ 4097.
If you are working with a camera that has 8192 pixels in each sensor line:
The AOI Starting Pixel can be set to 1, 33, 65, 97, etc.
The AOI Length can be set to 256, 288, 320, 352, etc.
The AOI Starting Pixel + AOI Length
≤ 8193.
