Basic Operation and Features

3.9 Area of Interest

The area of interest feature allows you to specify a portion of the CMOS array and during
operation, only the pixel information from the specified portion is transferred out of the camera.
The size of the area of interest is defined by declaring a starting column, a width in columns, a
starting line and a height in lines. Columns can only be chosen in multiples of 10 due to the way
the data is output of the sensor (see Figure 3-1). For example, suppose that you specify the
starting column as 11, the width in columns as 20, the starting line as 8 and the height in lines as
10. As shown in Figure 3-28, the camera will only transmit pixel data from within the defined area.
Information from the pixels outside of the area of interest is discarded.
Due to the video output, columns can only be selected in multiples of 10, that means from column 1 to column
10, column 11 to column 20, column 21 to column 30 and so on.
Figure 3-28: Area of Interest
You can set the area of interest using either the Camera Configuration Tool Plus (see Section 4.1)
or binary commands (see Section 4.2). You use the Area of Interest Starting Column, Area of
Interest Width in Columns, Area of Interest Starting Line and Area of Interest Height in Lines
commands.
Note that the binary commands start to count at 0.
