Sanyo VCC-WD8875P - Manual (Page 6)

Incorporates Premium Bayer Mosaic
RGB Filter
The “Advanced WDR” camera also makes use of the
acclaimed Bayer Mosaic RGB filter which extracts light’s
three primary colors (red, green and blue) from the CMOS
sensor to deliver highly realistic and vivid colors that allow
extremely accurate color reproduction.
Sophisticated Auto White Balancing
System
A new fully automatic tracing white balancing system makes
it possible to consistently achieve natural, lifelike colors that
reproduce subjects better.
Smearless
Conventional CCD cameras can often generate vertical noise
(smears) associated with bright spots. The new CMOS
sensor eliminates smeared images.
High Sensitivity, Minimum Illumination
of just 0.8 lux
With a sensor that measures just 1/3 of an inch, an immense
amount of light per unit area can be achieved while dark
areas are more effectively handled. A minimum illumination
of 0.8 lux (at F1.2) is all that is required for this sensor to
allow dimly lit subjects to be reproduced satisfactorily in
good color.
Digital Noise Reduction
A new digital noise reduction function minimizes S/N ratio
penalties conventionally incurred when processing dark
areas, improves the S/N ratio in low illumination conditions
and achieves images virtually free of noise.
Day & Night Function (VCC-WD8874)
The camera is able to evaluate screen brightness, turning
the infrared cut filter ON or OFF automatically when needed.
A single camera is adequate for 24/7 monitoring. The camera
takes color images which are easy to monitor during daylight
hours and switches to sharp black-and-white images of high
sensitivity at night or during periods of low illumination.
New and Advanced Linear Output Method
SANYO devised a new exposure method for increasing
visibility under varying conditions of light, weather and time.
The progressive exposure technology simultaneously outputs
image signals in low illumination areas and image signals in
high illuminance areas with no lag. Subjects are accurately
reproduced with natural gradation including subjects as well
as images with an incorrect white balance background that
previously could not be conventionally reproduced. This new
technology captures quick motions with great stability and
reproduces contours clearer and richer than before—an
advantage that conventional time lag exposure composition
methods could not expect.
