ROI Output Timing
The maximum eight regions of ROI is configurable.
The horizontal start pixel (ROI_PIX_START_x), vertical start line (ROI_LINE_START_x) and vertical effective lines
(ROI_LINE_NUM_x) are configurable for individual ROI region.
The horizontal effective pixels is common setting for all ROI regions.
The position of ROI region cannot overlap.

The vertical settings for ROI region
The region has more than 5,120 vertical start line (ROI_LINE_START_x) is invalid region.
It is necessary to set vertical effective lines (ROI_LINE_NUM_x) and vertical start line
(ROI_LINE_START_x) do not overlap other regions.
When overlapping regions or total vertical effective lines becomes more than 5,120 lines, subsequent
regions are invalid
The horizontal setting for ROI region
The horizontal effective pixels (ROI_PIX_NUM) is common setting for all regions.
The frame rate on ROI
The frame rate could be increasing with total vertical effective lines (ROI_LINE_NUM_x) of active ROI
regions.
The horizontal effective pixels (ROI_PIX_NUM) does not influence frame rate.
