1/3 inch-type 3 ClearVid CMOS Sensor
system
The newly developed 1/3-inch type 3 ClearVid CMOS
Sensor™ system has 45-degree rotated pixels on each
chip in order to increase the signal density, while each
pixel maintains sufficient surface area.
In combination with Enhanced Imaging Processor™ (EIP),
the 3 ClearVid CMOS Sensor system achieves high
resolution, high sensitivity, wide dynamic range, and
excellent color reproduction.
The pixel shift interpolation technique has been
traditionally used in small 3CCD camcorders. However,
it normally requires the combination of all three color
element (RGB) signals to maximize resolution. If an object
lacks one or more color elements, the
resolution of the object may be degraded.
The 3 ClearVid CMOS Sensor system is different. It can
always produce maximum resolution, regardless of the
balance between color elements, thanks to its unique
and sophisticated interpolation technology.
Cutting-edge imaging System for New Camcorders

Enhanced Functionality via the
Technology of “Exmor”
Both the HVR-Z7U and HVR-S270U offer cutting-edge
features, such as the technology of “Exmor™” developed
by Sony, which utilizes the full potential of the 3 ClearVid
CMOS Sensor system.
The technology of “Exmor”, which features the
column-parallel A/D conversion technique and the dual
noise cancelling method are also used in other latest
camera products from Sony.
Multiple A/D (analog to digital) converters on each pixel
row convert analog signals to digital as soon as they are
generated, unlike traditional technology that only has
one A/D converter on each chip. The technology of
“Exmor” can eliminate the influence of external noise that
enters the signal chain during transfer to the A/D
converter, resulting in high-quality digital signals with
extremely low noise. This significantly enhances shooting
in low-light environments.
By adopting this groundbreaking technology, the new
1/3-inch 3 ClearVid CMOS Sensor system enables the
HVR-Z7U and HVR-S270U to achieve a low light sensitivity
of just 1.5 lux*.
