Format_7 Mode_1: sensor readout and color
In Format_7 Mode_1 controlling gain is done digitally for each of the four
channels Cyan, Yellow, Magenta and Green.
Because it is not possible to obtain full color or chroma information per field,
the data has to be deinterlaced first. After that demosaicing is done (see
Chapter
How demosaicing works on page 108): luma (Y) and the two chroma
values (R-Y and B-Y) are calculated from each 2x2 pixel array.
