Color Creation on the acA750-30gc

The sensor used in this camera is equipped with a complementary plus green color separation filter.
The colors in the filter are cyan, magenta, yellow, and green (CMYeG). Each individual pixel is
covered by a portion of the filter that allows light of only one color to strike the pixel. The filter has
a repeating pattern as shown in Figure 71.

Because there is only one vertical shift register for every two pixels in the camera's sensor, when a
field is acquired, the colors from two pixels will be will be combined into a single "binned" pixel. As
shown in Figure 72, when the camera acquires field 0, it will obtain the following color combinations
for any group of four "binned" pixels:
Green + Cyan
Magenta + Cyan
Magenta + Yellow
Green + Yellow
