DESCRIPTION
FEATURES
The wide dynamic range that is engineered into TOA
DSP Color Cameras allow these extraordinary
cameras to deliver a performance that goes well
beyond the parameters of human eyesight. These
cameras provide natural images that are very similar
to what the human eye sees to make for easy and
non-tiring viewing. This quality is maintained under
adverse lighting conditions such as backlighting. And
enhanced night vision capability is also built in with a
high performance electronic sensitivity booster that
ensures clear images in color even under unsatisfactory lighting conditions.
● Wide dynamic range
Provides a new level of performance with natural
looking images even in backlight condition.
● Backlight compensation
Allows optimal viewing of dark areas in a
backlight condition.
● Maximum 32X sensitivity booster
Enables increasing sensitivity to take color images
even in night conditions.
● 480-line high resolution (PAL /NTSC)
● Newly developed DSP
● Fully automatic operation mode shift
● Easy menu-driven setup

WIDE DYNAMIC RANGE COLOR CAMERAS
New DSP
Crucial to achieving the extremely wide dynamic range
function is the new TOA proprietary DSP.
Using sophisticated digital video processing allows
electronically combining two separate images taken with
different shutter speeds to result in one perfect image.

Wide dynamic range
The C-CC351A and C-CC354A camera series achieve a
remarkable dynamic range . This reflects a performance level
that is 32 times greater than conventional CCD cameras.
The wide dynamic range allows optimizing an image by
automatically adjusting both dark and light areas to ensure
the targeted area has ideal contrast and visibility.
TOA Wide Dynamic Range Method
Conventional cameras employ a single speed of 1/60sec.
when taking images. TOA’s Wide Dynamic Range Method
makes use of two shutter speeds, one set at 1/120sec. and

Three modes cover dynamic range
requirements.
Normal is the default setting where the dynamic range
is adjusted automatically as needed as when the
camera detects a backlighting condition.
High-speed shutter loses details of

Low-speed shutter creates whiteout
of outdoor.
Electronically combining the images taken using both low-speed and
high-speed shutter gives single clear image.
Manual splits the screen into 12 segments and allows
the user to adjust the dynamic range for the most
desired segments.
Off is for when wide dynamic range adjustment is not
desired or when using the backlight compensation.

Backlight compensation
Maximum 32 times sensitivity boost
TOA's CCD cameras have been designed to overcome the
problems that conventional CCD cameras experience. Most
of these problems originate from trying to accurately focus
when the area of coverage includes areas with varying
brightness. Cameras in some cases are affected by the
bright areas they are monitoring with the result that there are
some hard to see dark areas. When backlight compensation
mode is selected, the camera divides an image into 12
segmented areas (4/4), comparing the brightness in each
area to automatically adjust the required amount of backlight
compensation for the desired segments. A greater degree of
control is allowed by setting backlight compensation for 3/4
which provides finer backlight control over the area most
important. 2/4 offers the finest degree of control by applying
12-segment backlight compensation to just the lower half of
the screen.
12 segmented areas (4/4) 12 segmented areas (3/4)
Magnification sensitivity can now be increased as needed all
the way up to x32 in steps of x2, x4, x6, x8, x10, x16, x24
and x32 to compensate for lighting conditions that may be
unsatisfactory. Sensitivity is boosted automatically to the
point where good images can be taken. A camera normally
requiring a minimum illumination of 1 lx can now operate
well at an illumination level as low as 0.03 lx. This amount of
sensitivity boost will now allow night video surveillance in
color.
* boosting sensitivity may increase the afterimage phenomenon as shutter
speed is reduced.
12 segmented areas (2/4)
When the backlight compensation function is on, the camera
can compensate for the different contrast levels in the
segmented areas. The user selects the image area that is
most important for viewing by segments. The backlight
function then works by adjusting light conditions
concentrating on the selected image area. The selected area
will be shown in the best possible condition, for more
effective monitoring.
Backlight compensation is automatically switched off when
the wide dynamic range function is used.

High resolution images
TOA cameras provide a high horizontal resolution level of
480 lines for excellent image quality.

automatically, smoothly transitioning from mode to mode.
