2.2.1
Horizontal and Vertical Window
o
e the beginning part of
each line (pixel 1 to ‘Start Pixel’) and the end of each line (‘End Pixel’ to
Last pixel) are ignored – Figure 2.9. The precision of each pointer
(beginning and end of the window) is 1 pixel, and can be placed in the entire
image area (in dual mode the horizontal AOI is symmetrical around the
image center) – refer to the camera configuration section. The minimum
window size is one pixel for single mode (or 2 pixels for dual mode), and
the maximum window size is the full resolution (Last H pixel). Table 2.2
shows the allowable values for the ‘Start Pixel’ and the ‘End Pixel’.
Emphasizing a particular area of inte
vertical direction is possible by
using a vertical window feature. Vertical windowing is used for increasing
the frame rates. For example, by skipping half of the lines, the image will be
sub-windowed by a factor of 2 and the frame rate will almost double. The
vertical window beginning (Start Line) and (End Line) can be programmed
with a precision of one line – Figure 2.21. The minimum window size is one
line, the maximum is full vertical resolution (Last V line). Table 2.2 shows
the allowable values for the ‘Start Line’ and the ‘End Line’.
Horizontal and vertical windowing (Area Of Interest) is supported in all IPX
cameras. Emphasizing a particular area of interest in horizontal directi n is
possible by using a horizontal window feature, wher
