2.2.3 External Line and Frame Time Control
The camera speed (frame rate) can be controlled using external sync pulses. The
camera line time can be slaved to an external H-Sync pulse, and the camera frame
time can be slaved to an external V-Sync pulse. The camera can be slaved to one or
both pulses. The H-Sync and V-Sync has to be mapped to corresponding camera
input. For more information, please refer to the I/O Control section.
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.
