3.6 Area of Interest (AOI)
The area of interest (AOI) feature allows you to specify a portion of the CMOS array and during
operation, only the pixel information from the specified portion of the array is transmitted out of the
camera.
The area of interest is referenced to the top left corner of the CMOS array. The top left corner is
designated as column 0 and row 0 as shown in Figure 3-9.
The location and size of the area of interest is defined by declaring a left-most column, a width, a
top row and a height. For example, suppose that you specify the left column as 10, the width as
16, the top row as 4 and the height as 10. The area of the array that is bounded by these settings
is shown in Figure 3-9.
The camera will only transmit pixel data from within the area defined by your settings. Information
from the pixels outside of the area of interest is discarded.
Figure 3-9: Area of Interest
The AOI feature is enabled by setting the camera to operate in Format_7, Mode_0. This is
accomplished by setting the Cur_V_Format control register (see page 4-8) to 7 and the
Cur_V_Mode control register to 0. The location of the area of interest is defined by setting a value
for the “left” field and a value for the “top” field within the Image_Position control register for
Format_7, Mode_0 (see page 4-11). The size of the area of interest is defined by setting a value
for the “width” field and a value for the “height” field within the Image_Size control register for
Format_7, Mode_0.
To use the entire CMOS array in
A600f monochrome cameras, set the value for “left” to 0, the
value for “top” to 0, the value for “width” to 656 and the value for “height” to 491.
To use the entire CMOS array in
A600fc color cameras, set the value for “left” to 0, the value for
“top” to 0, the value for “width” to 656 and the value for “height” to 490.
