today announced an updated version of its X3 Pro 10M sensor, this new
sensor is used in the new Sigma SD10 which has also been announced today.
While the sensor has the same resolution as that used in the SD9 (2268
x 1512 x 3) Foveon has finally taken the step to calling this a 10.2 megapixel
sensor. The new sensor is said to have improved dynamic range and color
response as well as increasing sensitivity by utilizing a microlens over
each pixel location, sensitivity for the SD10 is up to ISO 100 to 800
with ISO 1600 available as an extended option.
FOVEON INTRODUCES NEW 10.2 MEGAPIXEL DIRECT IMAGE SENSOR
Sigma SD10 Digital Camera First To Incorporate Improved Foveon Image
Santa Clara, CA (October 27, 2003) Foveon
Inc., a technology leader in high-quality digital photography, announces
the immediate availability of the F7X3-C9110, an enhanced version of the
Foveon X3® PRO 10M direct image sensor. The improved 10.2 megapixel
(red + green + blue pixels) image sensor doubles the sensitivity and maximum
exposure times and offers increased dynamic range over its predecessor.
The new Foveon sensor is used in the Sigma SD10 digital Single-Lens Reflex
(SLR) camera. The new Foveon X3® PRO 10M direct image sensor will allow users
to capture outstanding photographs at higher shutter speeds ideal for
sports action as well as in low light situations requiring long exposures
up to 30 seconds.
The new Foveon image sensor is a result of design and fabrication process
improvements that result in higher image quality and superb color fidelity.
These improvements demonstrate the speed at which we are evolving
the technology and support our confidence that X3 is the most advanced
image sensor technology for capturing color images, said Federico
Faggin, Foveons CEO.
The first camera to incorporate the new image sensor is the newly introduced
Sigma SD10 digital Single-Lens Reflex (SLR) camera. The camera supports
an ISO range from 100 to 800, plus an extended mode option to ISO 1600,
and exposure durations of up to 30 seconds.
The choice of image sensor is becoming a top criterion, when choosing
a digital camera, because it is the primary factor that determines the
image quality. We believe that with Foveon X3 technology, the Sigma SD10
digital camera offers color resolution and color fidelity comparable to
other cameras costing four times the price, said Faggin.
The Foveon X3 PRO 10M direct image sensor has a total of 10.2 million
red, green, and blue pixels that are organized into three layers (2268
x 1512 x 3 layers).
About Foveon X3 Direct Image Sensors
Foveon X3 image sensors are the worlds only direct image sensors,
which capture red, green, and blue light at every pixel location, and
are the first image sensors that leverage silicons inherent color
separation property. When silicon is exposed to light, blue light is absorbed
near the surface, green light is absorbed in the middle, and red light
is absorbed deep within the silicon. Pixel sensors are stacked at the
corresponding depths within the silicon so that red, green, and blue light
is captured for each pixel location.
Other image sensors on the market such as CCD and CMOS image sensors
have only one layer of pixels and use colored filters to capture a single
color per location, resulting in color artifacts and image blurring.
Foveon X3 technology is highly scalable for a wide range of cameras including
digital still/video cameras, PDAs, cell phones, security cameras and scientific
