Especially designed to capture clear, easy-to-view images
under poor or unpredictable lighting conditions such as in
multi-story car parks and at road junctions, this versatile
high-resolution camera features a wide-dynamic-range
digital image device that uses sophisticated multi-
sampling and a 14-bit DSP which accurately reproduces
natural color tones without any halation (blooming) or
smear. Even when the illumination suddenly changes —
becoming suddenly brighter or darker, or if the scene
includes both bright and dark areas, this camera still
captures a clear image that closely resembles what you
see with your own eyes.
1/3" WDR digital image device
Featuring a much wide dynamic range than conventional imaging
devices, the 1/3” WDR digital image device is able to respond quickly
and accurately to high contrast and sudden variations in lighting to
deliver high-quality, well-exposed pictures with no smear or blooming.
Equally effective in very bright or low-light conditions, this device is
capable of shooting at 1.9 lux (at F1.2, 50%, AGC HIGH setting), to
ensure quality imaging even of the most dimly lit subjects.
Innovative 14-bit DSP
To support the WDR image device, the TK-WD310U incorporates an
innovative 14-bit digital signal processing chip that adjusts the brightness
level of each individual pixel, so reproducing clear details of not only the
foreground subjects but also of the brightly lit background, such as the
situation with an entrance camera looking from a foyer into a sunny
street. A normal CCD camera could only correctly expose either the
background or the foreground, displaying the other as either dark
silhouette or burnt-out white, respectively. This means that even when
the camera is shooting in locations where there is a very high contrast
between light and dark, the captured images will come out looking clear
and natural. For example, car headlights can be captured without
smear, assuring easy identification of the number plate and so enabling
high-quality surveillance.
High-speed WDR (Wide Dynamic Range) with automatic 5-level exposure
control for each pixel
For smooth, accurate imaging, the wide dynamic range function uses a
high-precision multi-sampling system that controls exposure with 5-level
sampling of each image pixel within a single frame.
480 TV lines of horizontal resolution
With horizontal resolution of 480 TV lines (typical) and vertical resolution
of over 400 lines, this camera captures sharp, clear images that make it
an ideal source for high-quality, finely detailed video recordings.
Programmable menu with selector operation
A convenient on-screen menu with selector operation is provided for
easy adjustment of various system parameters including focus control
and camera settings. The factory default settings can be restored easily,
if so required.
White balance: Automatic (ATW)/single-push (AWB)/manual (MANUAL)
ATW, AWB and MANUAL modes are available. The ATW mode
automatically adjusts white balance according to changes in lighting
conditions (2,500°K to 10,000°K). The AWB/MANUAL mode
automatically or manually adjusts and locks the white balance for specific
lighting conditions.
Notes:
1. The WDR function will not operate with AGC or slow shutter mode engaged.
2. The video pictures can become noisy in high extremes of temperature (over 35°C / 95°F),
when also the operation of the slow shutter function may become problematic.
3. In very dark conditions the image quality may suffer slight deterioration.
4. Under fluorescent lighting, the color balance may vary slightly.
5. Fluctuations in the AC mains frequency can cause beat noise, when the camera is in Line-
Lock mode.
6. All manufacturer utilizing this technology will experience similar phenomenon.
