| High-Performance Full-Frame CCD |
|
| The E-1 uses a high-performance full-frame CCD. The advantage of full-frame transfer
type CCDs is that in comparison to the interline CCDs used in most consumer-use
digital cameras, the active pixel area of each photodiode in the sensor is much
larger, allowing a greater range of image data to be captured. In addition, interline
CCDs transfer image data out to 'shift registers,' and the design demands of this
type of system effectively limit the amount of data the individual photodiodes
can store at one time. Full-frame CCDs, on the other hand, do not require the
use of shift registers, thus allowing the photodiodes to store much more information.
As a result, full-frame CCDs can effectively capture approximately twice as much
image data as interline CCDs, giving them greater dynamic range, with low noise
and high grayscale sensitivity that ensure improved shadow and highlight detail. |

| Dust Reduction System |
|
| The E-1 also features an exclusive new Olympus-developed Dust Reduction System
that significantly reduces problems caused by image sensor dust contamination.
Such contamination can occur if dust enters the camera when changing lenses, or
is generated by the friction of the shutter or other moving parts inside the camera.
The system utilizes a Supersonic Wave Filter positioned in front of the CCD, between
the low pass filter and the shutter. The dust that is captured by the filter can
then be instantly removed by ultrasonic activation prior to shutter release. In
addition, the CCD and low pass filter are hermetically isolated from the rest
of the camera to help prevent dust from reaching them. Thanks to this new Dust
Reduction System, users can more consistently obtain beautiful photos because
the chance that image quality will be degraded by stray dust particles is greatly
reduced. |
