INTRODUCTION
SuperExwave™ Technology
(SSC-E470 Series/SSC-E450 Series)
During nighttime monitoring applications, camera
sensitivity is one of the most important factors in
capturing a clear image.
Sony cameras that incorporate SuperExwave technology
achieve extremely high sensitivity levels especially in the
near infrared wavelength region of the electromagnetic
spectrum. As a result, sensitivity levels in the visible
wavelength region are increased by approximately 10 %,
while the sensitivity in the near infrared region is increased
by approximately 50 % when compared to Exwave HAD
technology. Sony SuperExwave cameras employ advanced
photo-diode sensors capable of capturing a great amount
of light in the near infrared region while efficiently
converting this light to electric signals thus achieving high-
sensitivity levels.
DynaView™ Technology
(SSC-DC590 series/SSC-DC570 series)
Newly developed DynaView technology achieves an
incredible dynamic range that is 128 times wider than
conventional cameras. Users can capture clear images
even in extreme high-contrast lighting environments. By
activating the DynaView mode, the camera will capture
the same image twice - first with a normal shutter speed,
and then with a high shutter speed. The newly developed
LSI technology then combines the dark areas captured at
normal shutter speed with the bright areas captured at
high shutter speed to create one image.
The result is an extremely high-contrast picture that is
unattainable with a conventional camera. (See Fig. 3)
Additionally, DynaView technology allows the cameras to
achieve more powerful Back- Light Compensation (BLC).
While conventional BLC can result in over exposure when
capturing background images, DynaView reduces this to a
minimum by using a high shutter speed for the
background, which consequently provides optimum
exposure for both the subject and the background.
