New Digital Design
To produce high quality
video, we have adopted new digital processing
ASICs, used in broadcast cameras. The use of
a six-axis linear matrix system enables fine
tuning of color.
The HC-400/400W provides a natural look and
stability not possible by analog cameras of the
past.
Double Lineup
The HC-400 features a fixed
4 : 3 aspect ratio, using newly developed high-
sensitivity 2/3" IT CCDs, each with approx.
410,000(NTSC) or 470,000(PAL) pixels.
The HC-400W is equipped with the latest
16 : 9 IT sensors to switch camera aspect
ratios(16:9/4:3).
This version employs 2/3" IT CCDs with 520,000
pixels(NTSC) or 600,000 pixels(PAL).
Low Smear and High Sensitivity CCD
The high quality CCD was selected under the
harshest guidelines for image quality, with a low
smear level of -120dB. It has a dynamic range
of 600%.
With a minimum illumination of 0.5 lx and a
sensitivity of f11(Specifications that rival
broadcast-quality cameras).
High Resolution
The HC-400/400W achieve
a natural picture quality with high horizontal
resolution of 800(HC-400),750(HC-400W) TV
lines. Vertical resolution can be upgraded by
20% to 480(NTSC),570(PAL) TV lines with the
Super-V function, achieving better balance
between vertical and horizontal resolution.
DTL
In the HC-400/400W, three special types
of DTL Detail enhancement are provided.
Skin DTL
The skin DTL function is used when
skin quality is being emphasized. The edge
sharpness in the skin color can be softened,
providing a more vouthful appearance of the
talent. This is Emmy-award winning broadcast-
camera feature is built into the HC-400/400W.
Soft DTL
Soft DTL function ensures against
excessively sharp edges between areas of
great contrast. DTL on parts with greater
differences in gradation is reduced to obtain
images that are more natural.
Diagonal DTL
Diagonal DTL function
Q u a l i t y
increases sharpness in the diagonal direction. It
extracts diagonal parts of image signals to
generate edge signals. In addition to increasing
the resolution of the picture, the function also
helps reduce cross color moire.
DTL Setting
A function for DTL boost
frequency variation, which can select eight
levels for the central frequency of edge signals
(2.8MHz to 7.0MHz), and a function for B/W
balance, where the central DTL brightness can
be set, are incorporated in the HC-400/400W.
These functions enable DTL to be used more
effectively in the field.
Black Stretch
The black stretch function
meets the needs of professional cameramen
who want to avoid excessive dark areas in high
contrast scenes. With three settings (3, 5, and
7%), this function enables improvement in dark
areas of pictures by lifting the image level of
only areas of low brightness.
36dB Gain Up
Gain is often used in dark
environments is improved. Gain can be set to a
maximum of 36dB. Also, because any gain level
can be assigned to the MID and HIGH
switches, cameramen can maintain optimum
video under varying lighting conditions merely
by flicking a switch.
Preset and Variable Shutters
shutter has five speeds (1/100, 1/120, 1/250,
1/500, 1/1,000, 1/2,000 seconds) and speeds of
between 1/60.3 and 1/201 (NTSC), 1/50.3 and
1/200 (PAL) seconds can be set on the variable
shutter.
Backlight Compensation
A backlight
compensation switch is used with automatic iris.
By opening the lens iris by approximately one
stop, this function enables fast shooting in
scenes with great contrast.
Electric Color Temperature
Compensation Circuit
An electric color
temperature compensation circuit, which
automatically compensates for daylight color
temperature, is included. The AWB can be set
without worrying about filter selections.
