The DP1x's Foveon X3® direct
image sensor utilizes the
special features of silicon,
which is penetrated to
different depths by different
wavelengths of light, to
successfully achieve full-color
capture for the first time ever
in a single-chip configuration.
No color filter is required.
Since the X3 can capture all the
color information in its three
layers, the aforementioned
late-stage color interpolation
necessitated by the Bayer filter
image-sensor is not required,
and exquisite, nuanced color
expression can be created in
pixel-location units. Compared
with the color-fudging Bayer
filter image sensor, the X3
takes color resolution to a
new and truly amazing level.
Since it does not need a color
filter, the direct image sensor
does not generate color
artefacts. This, of course,
means that no optical low-
pass filter is needed either.
This full-color capture system
can cope with all kinds of
high-frequency areas, and
capture the full complement
of colors. That's why the
results are both absolutely
natural and truly exquisite.
The Bayer filter Image Sensor
The old-fashioned Bayer filter image sensor
can only capture 50% of the green color data,
and a mere 25% each of the blue and the red.

The Foveon X3® Sensor
The Foveon X3® has three layers of
photosensors, enabling it to capture 100%
of the RGB color data at once.
