Frame rate [fps] = 1 / read-out time [sec]
(1.1)
The user can program the camera to run slower than the nominal speed
preserving the camera full resolution. The user can independently extend the
camera frame time (the time required to read the entire frame out of the CCD
imager). The camera frame time can be extended to ~ 16 sec, with a precision
of ~ 1.0us. Please refer to “EXPOSURE CONTROL” section for more
information.
Note: Long integration doesn't interrupt HD-SDI output. Frame is captured in
the Camera frame buffer. Frame is repeated on the HD-SDI output. Amount of
repeating depends on the camera frame time.
2.2.2.
External Frame Time Control
The camera speed (frame rate) can be controlled using external tri-level sync
input.

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 6
(six) Horizontal and Vertical Areas of Interest (AOI) 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 2.2. The
minimum window size is two pixels/lines. The maximum horizontal window
size (H) and the vertical window size (V) are determined by image full
resolution as shown in Table 1.6.
