Features
Signal-to-noise ratio 63 dB (NTSC)/61 dB
(PAL)
The camera gives a clear picture with very low noise
levels.
Horizontal resolution of 800 TV lines
The 420,000-pixel imaging element pushes CCD
technology to the limits of quality.
DCC+ (dynamic contrast control - plus)
This feature improves on the conventional DCC
feature (preventing white breakup when shooting a
high intensity subject), further preventing color faults
in high intensity subjects.
Digital image enhancer
The digita! implementation of the outline
compensation function provides a stable picture, with
reduced aliasing" and spurious modulation",
High sensitivity (f/8.0, 3200 K, 2000 lux)
This allows poorly lit scenes, even under candlelight,
to be shot.
White shading" compensation circuit
This is adjusted to the state of the camera when
shipped.
Flare compensation circuit
When shooting a bright subject, this prevents graying
or color casts in dark portions of the picture.
Ideal gamma compensation curve
This provides high detail quality, with no loss of
quality in hair tones and other dark parts of the picture.
"Clean detail" circuit
This prevents "jaggies" on diagonal lines.
1) Aliasing (moiré): this produces jagged patterns when
the subject has a fine mesh pattern. These are also
known as moiré patterns.
2) Spurious modulation (ghosts): these are duplicate or
triplicate images of a bright subject when shot in dark
surroundings.
"Easy mode" for instant operation
This allows you to shoot immediately when there is
insufficient time to check the camera settings, with
automatic adjustment to standard settings.
"Easy focus" function
You can set the focus accurately and easily before
shooting.
Programmable gain
You can choose the gain values assigned to the H, M
and L settings of the GAIN switch from the following:
~3 dB, 0 dB, 3 dB, 6 dB, 9 dB, 12 dB, 18 dB and 24
dB.
Hyper gain
A single switch operation raises the gain by a factor of
about 60 with respect to 0 dB (that is, increased to 36
dB).
Auto tracing white balance function
Even if the lighting conditions change continuously,
the white balance automatically follows. This is useful
when there is no time to adjust the white balance, or
when shooting while moving indoors or outdoors.
Auto irls compensation for backlighting or
spotlighting
When using the auto iris function, it is possible to
automatically compensate the iris adjustment for
backlit or spotlight scenes.
Dual pixel readout function
When the gain setting is 18 dB or 24 dB, this function
lets you raise the gain to double (6 dB up), without
increasing the noise level.
3) White shading: this causes variation in the color of a
white subject away from the center of the screen.

Features
Three-position color matrix
You can switch the color matrix among three settings
to change the picture color adjustment.
Recording time display
You can display either of the following recording time
indications:
¢ The total recording time so far
® The recording time for the current cut
Viewfinder super detail
The video signal for the viewfinder can be mixed with
a V-DTL (vertical detail) signal, for easy focusing.
Two selectable indication levels for the zebra
pattern
You can select the reference level for the zebra pattern
indication at an IRE image level of either 65% to 75%
or 100% and above.
Color temperature indications
After the white balance is set, the color temperature
appears in the viewfinder.
Video output with character information
You can output video to an external monitor with the
same character information as shown on the
viewfinder screen.
"|
Camera microphone output indication
An indication (») appears in the viewfinder when there
is an output signal from the camera microphone.
Reference signal (1 kHz) output
With the color bars, you can output a 1 KHz reference
signal.
Shoulder pad position adjustment
You can adjust the shoulder pad position front to back
for optimal balance for shoulder operation.
High performance viewfinder (DXF-601/601CE)
¢ Horizontal resolution of 600 TV lines
¢ Large aperture, allowing a picture check even when
your eye is away from the viewfinder
« Variable peaking
¢ Rugged aluminum die-cast body
When a PVV-3/3P is connected, you can display the
following information from the VTR in the viewfinder.
Time data (time code, CTL count, or user bit value)
¢ VTR audio levels
¢ Remaining tape time
© VTR operating state
¢ Remaining battery capacity (when using an Anton
Bauer Intelligent Battery System)
