Use the "Settings" button to define how the
B&W image is generated. You can either select
to use the luminance channel of the picture or
make your own channel mix of Red, Green and
Blue channels. If the total sum (in percentage)
of Red, Green and Blue is not 100%, you can
use softkey 3 (100 %) to normalize this.
