Sharpness

All Marlin color models are equipped with a two-step sharpness control,
applying a discreet horizontal high pass in the green channel as shown in the
next three line profiles.

Color interpolation and correction

The color sensors capture the color information via so called primary color
(R-G-B) filters placed over the individual pixels in a BAYER mosaic layout.
An effective Bayer

RGB color interpolation already takes place in all Marlin

color version cameras. Before converting to the YUV format, color correction
is done after BAYER demosaicing.

Color processing can be bypassed by using the so called RAW image transfer.

RAW mode is primarily used to

save bandwidths on the IEEE 1394 bus

achieve higher frame rates

use different BAYER demosaicing algorithms on the PC
