There are 4 light shielded rows followed by 1084 photoactive rows and finally 4 more light shielded rows. The first and
last 2 photoactive rows are buffer rows giving a total of 1080 lines of image data.
In the single output mode all pixels are clocked out of the Video L output in the lower left corner of the sensor. The
first four empty pixels of each line do not receive charge from the vertical shift register. The next 28 pixels receive
charge from the left light shielded edge followed by 1928 photoactive pixels and finally 28 more light shielded pixels
from the right edge of the sensor. The first and last 4 photoactive pixels are buffer pixels giving a total of 1920 pixels
of image data.
In the dual output mode the clocking of the right half of the horizontal CCD is reversed. The left half of the image is
clocked out Video L and the right half of the image is clocked out Video R. Each row consists of 4 empty pixels
followed by 28 light shielded pixels followed by 964 photoactive pixels. When reconstructing the image, data from
Video R will have to be reversed in a line buffer and appended to the Video L data.
