AK-HC3500
Powerful multi-format digital camera with a new
IT-3CCD delivering 1080i native resolution
High image quality, easy operation and outstanding reliability
from a new generation HD multi-format camera
The AK-HC3500 is the zenith of advanced camera design. In addition to a unique 2/3-inch IT-3CCD and spatial
offset processing technologies, it offers a newly-developed 14-bit A/D converter and 38-bit Digital Signal
Processing LSI for exceptional image quality. To satisfy the demands of shooting in the field, it also features an
ergonomic design for easier, more comfortable use. Add to this outstanding performance, and you have the ideal
studio and field multi-format camera for the high definition era.
Switchable output HD/SD formats
The AK-HC3500's multi-format capability makes it perfect for
demanding broadcasts and program production at home and
abroad. Using the optional down converter board also enables
HD to SD signal (480i/576i) conversion.

Panasonic's unique high sensitivity, low smear 2/3-inch 2.2-megapixel IT-3CCD
Panasonic CCD sensor technology and the improved on-chip
lens performance offers a high sensitivity of F10 (1080/59.94i)
/F11 (1080/50i) at 2 000 lx, a low smear level and an excellent
signal to noise ratio of 60 dB.

14-bit A/D converter and latest 38-bit Digital Signal Processing (DSP)
provide clear, sharp images from dark to bright areas.
A/D conversion is 14-bit compared to conventional 12-bit. There's also a newly-developed 38-bit Digital Signal
Processing (DSP) and Panasonic's original real-time gamma correction to enable high quality images with Dynamic
Range Stretch (DRS) and other high-performance functions.
Before correction After correction
Dynamic Range Stretch (DRS)
Function
DRS helps assure high image quality
when shooting extremely contrasty
scenes. It's also effective when shooting
standard scenes because it avoids
aliasing (knee artifacts) which can be
unattractive for on-screen talent.
Cine Gamma Curve
Thanks to its cine gamma curve, the
AK-HC3500 can produce pictures with
the same kind of tonal beauty, natural
gradation, and rich colors you get with
film recordings.
When the gamma curve
is adjusted based on
bright areas of the image,
black blocking occurs.
When adjustment is based
on dark areas, some image
parts are washed out.

Color Correction
The 12-vector variable masking circuit
allows precise and independent hue
and saturation adjustment of individual
colors.
Skin Tone Detail Correction
Separately defocusing two skin tones
helps tone down wrinkles and dull
areas to produce beautiful, naturally
textured results when shooting people.
And since defocusing is possible
throughout the entire hue phase (360°),
defocusing can also be applied for
colors other than skin tones.
Enhanced DTL Signal
Processing
Enhanced DTL signal processing
ensures superb picture quality with
minimal noise in horizontal and vertical
directions, as well as in the image's
dark and brightly lit areas.
Color correction restricted to the red colors.
