Region of Interest (ROI)

This feature specifies the X-Y coordinates for the Region of Interest (ROI). The
region of interest coordinates are defined as follows:
•
•
•
•
52
Where xmax is the x-size of a full size image (1279
pixels), and ymax is the y-size of a full size image
(1023 pixels).
For example, a coordinate set of 0, 639, 512, 1023 will
produce the bottom left section of a full size image.
Picture coordinates are NOT defined on a Cartesian coordinate
plane.
NOTE
Byte [0]-[1]: 16 bit hex value xmin
Byte [2]-[3]: 16 bit hex value xmax
Byte [4]-[5]: 16 bit hex value ymin
Byte [6]-[7]: 16 bit hex value ymax
If the xmax/ymax values are configured larger than the maximum
values above, they will default to 1 less than their respective max-
imum values.
If the xmin/ymin values are configured larger than xmax/ymax,
NOTE
they will default to 0.
