AREA OF INTEREST
2.2.1
Horizontal and Vertical Window
Horizontal and vertical windowing (Area Of Interest) is supported in all
LYNX cameras. Emphasizing a particular area of interest in horizontal
direction is possible by using a horizontal window feature, where 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 – 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 interest in 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 2.26. 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’.
