Table 33 - Description of the SFNC registers associated to single ROI support
Name Access Values Description
Sparse
RW ON/ OFF
(Boolean) Controls whether the region is contiguous or split in
different areas.
Width
RW 8, 16, …,
WidthMax
Width of the image provided by the device (in pixels).
Height
RW 16, 32, …,
HeightMax
Height of the image provided by the device (in pixels).
OffsetX
RW 0, 7, …,
WidthMax-8 Horizontal offset from the origin to the region of interest (in
pixels).
OffsetY
RW 0, 15, …,
HeightMax-16 Vertical offset from the origin to the region of interest (in
pixels).
Definition of a single ROI.
Multiple ROI support
The sensor allows to define different ROIs by selecting multiple set of active columns and rows, the
active area corresponding to the intersection of the defined ranges.
To define multiple ROIs, the proprietary
Sparse
register must be set to TRUE.
Note that once
Sparse
is set to TRUE, the standard registers
Width, Height, OffsetX, OffsetY
are read
only and are automatically computed by the camera. Note that
SparseMode
is always TRUE for the first
set of columns/rows.
The user can define up to 8 sets of active columns and rows. This allows to specify a total of 1, 4, 9, 16,
… or 64 areas.
