Features and Functions of the AK-HC3500A Studio Handy Camera
The AK-HC3500A is an HD camera with optical fiber transmission capability that meets the needs of high-end broadcast work
for shooting live relays, producing TV programs, and more. Its 2/3 type 2.2-megapixel 3CCD provides high sensitivity, low
noise, and low smear, while pixel-shifting technology ensures high resolution, and a 16-bit A/D processing circuit delivers rich
gradation. HD multi-formats, including 24P, 25P and 30P, and filmlike gamma curves allow the AK-HC3500A to handle a wide
variety of TV program production tasks. Combined with a Camera Control Unit (CCU), Master Setup Unit (MSU), and Remote
Operation Panel (ROP), this camera can be configured into a long-distance optical transmission system with stunning image
quality and uncompressed digital signals. A wide range of system options are
also available, such as a Build-up Unit and LCD Viewfinder.
3CCD with High Sensitivity, Low Noise and Low Smear
The 2/3 type 2.2-megapixel 3CCD enables standard sensitivity of
F11 (2,000 lx/50 Hz), F10 (2,000 lx/59.94 Hz),which is one of the
highest levels in this camera range. A high S/N ratio of 60 dB (at
59.94 Hz) produces high-quality images with low noise and low
smear. Panasonic's single-channel transfer system and spatial-
offset processing technologies also improve signal modulation
depth and reduce moire.

With spatial-offset processing, green
samples are offset, allowing change in the
object to be more faithfully reproduced.
HD Multi-Formats — Including 24p/25p/30p
In addition to 1080/59.94i and 1080/50i, the AK-HC3500A supports
1080/29.97p (over 59.94i), 1080/25p (over 50i) and 1080/23.98p
(over 59.94i)* HD formats. This allows it to handle a wide variety of
production tasks for series-type and other TV programs.
*The AK-HCU355A enables conversion to 1080/23.98p (over 47.96i).

New High-Performance DSP Provides 16 bit A/D,
38 bit Processing
HD images are digitized with
74-MHz sampling and 16 bit
A/D conversion. Full 38 bit
processing within the DSP
produces highly detailed, high-
quality images.
Dynamic Range Stretch (DRS)
The DRS function automatically suppresses blocked shadows and
blown highlights. A gamma curve and knee slope are estimated to
match the contrast of each pixel, and applied in real time. When
dark, bright, and intermediate shades are all contained in the same
scene, this produces excellent gradation for each shade. The
images that result are enhanced by a visually wide dynamic range.
Five Selectable Gamma Curves
Selectable gamma curves are included in the DSP circuit.
The Film Rec mode and Video Rec mode produce the kinds of film
tone that you get with Panasonic VARICAM models. There are five
modes altogether, including Filmlike 1/2/3. They produce HD
images with a film-like quality, natural gradation, and vivid color
reproduction.
Color Correction
The 12-axis color correction function allows precise and
independent hue and saturation adjustment of individual colors.
