Sigma SD 9 사용자 설명서

Unlike the SIGMA SD9, other digital cameras’ image quality

is inherently compromised. Conventional image sensors use

a single layer of pixel sensors which are organized in a three-color

 checkerboard mosaic. Each pixel location has one pixel sensor 

and captures just one color component  — red or green or blue. 

Regardless of pixel count, mosaic-based image sensors capture

only one-third of the information that FOVEON

full - color

image sensors capture per pixel location, and rely on complicated

time and energy- consuming processing to interpolate the two -

thirds of all the information they miss at each pixel. This leads to

color artifacts, loss of image detail, and other disadvantages.

A conventional
image sensor fea-
tures color filters
applied to a single
layer of pixel
sensors in a tiled
mosaic pattern.

The filters let only one
wavelength of light —
red, green, or blue —
pass through to any given
 pixel location. The pixel
location records only that 
one color,so the other imfor- 
mation at that site is lost.

As a result, conventional
mosaic image sensors cap-
ture only 25% of the R
(red), 25% of the B (blue),
and 50% of the G (green)
light.

The FOVEON

X3

™

image sensor 
comprises three 
layers of pixel 
sensors embed-
ded in silicon.

Silicon absorbs different
colors, or wavelengths,
of light at different
depth, so each layer
captures a different
color among R, G, and
B. The stack of three
layers creates a full-
color pixel.

Only the FOVEON

image sensor captures R,
G, and B light at every
pixel location.

Founded in California in 1997, FOVEON Inc. is world - renowned for

image sensors, user interfaces, and image/digital processing technology.

Digital photos have never looked quite as good as those taken on film. Until now. 

Only the SIGMA SD9 digital single-lens reflex camera makes this major breakthrough. 

Using FOVEON

® 

X3

™  

 technology with over 10.2 million pixel sensors for more accurate, efficient color  

reproduction, and sharper resolution, pixel for pixel, than any conventional CCD or CMOS image sensor provides. 

So you can capture more of your vision in a truer light.

Go ahead. Get more creative. The SIGMA SD9 puts the advantage of 

higher technology right in your hands.

The FOVEON

® 

X3

™ 

image sensor is  the heart of the first

and only full-color capture system for digital cameras. The X3.  

image sensor uses three silicon-embedded layers of 

pixel sensors, stacked to take advantage of silicon’s ability to

absorb red, green and blue light at different respective depths.

A FOVEON

®

X3

™

image sensor can thereby capture full color

and detail at each and every pixel location.

The results are a revelation : better color detail, fewer color

artifacts and three times the image sharpness, compared to that

delivered by more conventional image sensors.
