2.3 AREA OF INTEREST
2.3.1 Horizontal and Vertical Window
For some applications the user may not need the entire image, but only a portion of
it. To accommodate this requirement BOBCAT provides total of 8 (eight)
Horizontal and Vertical Areas of Interest (AOI) – one Master, 6 Slave and one
Processing. The starting and ending point for each AOI can be set independently in
horizontal direction (Horizontal Window) and vertical direction (Vertical Window),
by setting the window (H & V) offset and (H & V) size – Figure 2.7. The minimum
window size is one pixel/line for single mode and two pixels/lines for dual mode.
The maximum horizontal window size (H) and the vertical window size (V) are
determined by image full resolution as shown in Table 2.1, and the selected size of
LVAL and FVAL.

A.
Master AOI (MAOI)
The MAOI can be set to preserve or to change the camera frame rate. When the user
wants to preserve the camera frame rate the MAOI settings will control only the
image H & V dimensions. When the user wants to take advantage of the reduced
vertical image size and increase the camera frame rate, the image maximum camera
speed will be determined by the V size of this MAOI. The image resolution will
reflect the MAOI H & V settings.
