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:
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.
NOTE
Picture coordinates are NOT defined on a Cartesian coordinate plane.
• 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
NOTE
If the xmax/ymax values are configured larger than the maximum values
above, they will default to 1 less than their respective maximum values.
If the xmin/ymin values are configured larger than xmax/ymax, they will
default to 0.
Images extracted with ROI must be in JPG format.
