PIXEL DATA FORMAT
Pixel Array Structure
The AR0130 pixel array is configured as 1412 columns by
1028 rows, (see Figure 5). The dark pixels are optically
black and are used internally to monitor black level. Of the
right 108 columns, 64 are dark pixels used for row noise
correction. Of the top 24 rows of pixels, 12 of the dark rows
are used for black level correction. There are 1296 columns
by 976 rows of optically active pixels. While the sensor’s
format is 1280 x 960, the additional active columns and
active rows are included for use when horizontal or vertical
mirrored readout is enabled, to allow readout to start on the
same pixel. The pixel adjustment is always performed for
monochrome or color versions. The active area is
surrounded with optically transparent dummy pixels to
improve image uniformity within the active area. Not all
dummy pixels or barrier pixels can be read out.

Default Readout Order
By convention, the sensor core pixel array is shown with
the first addressable (logical) pixel (0,0) in the top right
corner (see Figure 6). This reflects the actual layout of the
array on the die. Also, the physical location of the first pixel
data read out of the sensor in default condition is that of pixel
(112, 44).
