3 ClearVid CMOS Sensor Imaging System
The ClearVid CMOS Sensor TM has been developed using the
most advanced technologies in the semiconductor industry.
Thanks to the unique grid arrangement of the photo diode
sensors, in which each is rotated by 45 degrees, sensor
resolution has been optimized and the photosensitive surface
area has been maximized.
The HVR-V1U employs a 3-chip ClearVid CMOS Sensor
imaging system, which produces high-resolution (1920 x 1080)
images with rich and natural colors. The combined use of the
3 ClearVid CMOS Sensor imaging system and the Enhanced
Imaging Processor
TM
technology has enabled a most precise
interpolation scheme, which concludes within each R, G, and
B channel. This allows a higher resolution for each R, G, and
B channel than is offered by equivalent-class camcorders that
resort to spatial offset techniques to improve resolution.
Unlike CCD sensors, there is no vertical smear in the ClearVid
CMOS Sensor imaging system when shooting high-intensity
subjects, further reducing shooting-condition constraints.
HDV Format
Enhanced Imaging Processor (EIP) Technology
The EIP is a newly developed imaging processor that brings
out the full power of the 3 ClearVid CMOS Sensor imaging
system. It handles video data in 1920 x 1080p and 4:2:2
color space for high-quality signal processing before recording it
to tape in the HDV format* 3 . Combined use of the EIP and 3
ClearVid CMOS Sensor imaging system allows the HVR-V1U
camcorder to provide extremely high image quality with a
high level of gradation and detailed image reproduction.

The HDV recording is in 1440 x 1080i and 4:2:0 color space.
Carl Zeiss Vario-Sonnar T Lens
The HVR-V1U is equipped with a high-quality Carl Zeiss Vario-
Sonnar T lens. Thanks to its multi-layer coating and extra-low
dispersion glass, this lens offers excellent spectral characteristics,
which result in virtually negligible chromatic aberrations.
Optical 20x Lens and
Optional 0.8x Wide Conversion Lens
The Vario-Sonnar T lens of the HVR-V1U features a 20x zoom
function. Moreover, the built-in digital extender* 4 increases the
zoom ratio to approximately 30x. The optional VCL-HG0868K
0.8x wide conversion lens uses the bayonet mount system for
instant attachment or detachment. Combining these lens
features, operators can effortlessly capture close-up or
wide-angle shots as their video production requires.
* 4 The digital extender function is not available in progressive scan modes.
Super SteadyShot System (Optical)
The HVR-V1U employs the Super SteadyShot ® system, which
has sensors that detect horizontal and vertical movements
independently. It uses a prism system located behind the lens to
adjust and optically compensate for unsteady camera handling.
Innovative Technologies
From the outset, the HDV 1080i specification of the HDV* 2
format was developed to record stunning HD images with
1080 active scanning lines on DV cassette tapes. It adopts the
MPEG-2 compression format, using 8-bit digital component
recording at approximately 25 Mb/s, which is the same data
rate as the DVCAM/DV format, enabling a long recording
time on compact DV cassettes.
For example, more than 60 minutes of high-quality HD images
can be recorded on a mini DV cassette. As with the DVCAM
and DV formats, the HDV format allows an i.LINK ®*6 connection
to compatible nonlinear editors, enabling a cost-effective
HD production system. The sheer volume of HDV 1080i
professional and consumer equipment used around the world
is a clear indication that HDV 1080i has become one of the
most popular HD formats.
* 2
Although not used in Sony HDV products, the HDV format also defines the HDV 720p
specification, which features 720 effective scanning lines (progressive scanning system).
Long Recording Time
The HVR-V1U uses mini cassette tapes and provides a maximum
recording time of 63 minutes with the PHDVM-63DM.
