Overview
The HDC2500 is 2/3-type high-definition portable video
camera equipped with CCD for 2,200,000 pixels.
Features
High picture quality and high performance
HDC2500 features a 2/3-type wide progressive IT CCD for
2,200,000 pixels and a signal processing LSI, both newly
developed to help achieve a high level of image quality via
improved S/N, high resolution, and low smear compared to
previous models. A 16-bit AD converter allows for optimal
picture quality and enhanced black reproduction.
Slow motion via 2× speed recording
1080/50i-59.94i and 720/50P-59.94P formats are supported,
as well as 1080/23.98PsF-24PsF-25PsF-29.97PsF and 1080/
50P-59.94P progressive formats, and 1080/100i-119.88i and
720/100P-119.88P slow-motion 2× speed recording formats.
For the models that do not support this function by default, use
optional accessories to use this function. For details, see
"Optional Accessories" (page 7).
Standard 3G optical digital transmission unit
3G optical digital transmission of signals between the camera
and camera control unit (CCU) is included, and allows the
following kinds of video signal transmission and system
configurations:
• 1080/50P-60P progressive video signal transmission
• Transmission of 2× speed recording signals such as 1080/
100i-119.88i for production of slow-motion video
• Transmission of HD prompter, HD TRUNK, and network
TRUNK signals that utilize empty bands during 1080/50i-60i
and 720/50p-60p operation
• Dual camera system for transmitting video signals from two
HDC2500 cameras to two CCUs using just one optical fiber/
multi-cable
• Subcamera system for transmitting video signals from both
an HDC2500 and another subcamera—such as the HDC-
P1—using just one optical fiber/multi-cable and outputting
their signals from one CCU
Various color-reproduction functions
Adaptive-matrix function
This function accurately controls calculation factors for
performing accurate color conversion when shooting. This
makes precise color conversion possible even when shooting
under conditions that would otherwise exceed the color
conversion range of traditional matrix functions, such as under
strong monochromatic blue light sources.
Multimatrix color correction
In addition the standard 6-axis matrix function, the camera has
a multimatrix function that permits you to adjust the hue and
chroma for color components in 16-axis directions
independently. This is quite useful in color matching among
multiple cameras.
Knee saturation
Change of hue and decrease in chroma that occur in
highlighted areas can be compensated.
This enables reproduction of natural skin tones under strong
lighting.
Low key saturation
Saturation in low-key zones can be compensated. Thus,
compensation for color reproduction in all zones is enabled in
combination with matrix color compensation and knee
saturation functions.
Selection of multiple gamma tables
Seven types of standard and 4 types of hyper gamma tables
are provided with this camera. The hyper gamma values
enable cinemalike image creations with wide dynamic range,
which are different from those achieved with conventional
video gamma.
User gamma
Gamma tables created with CvpFileEditor™ can be saved to
a "Memory Stick," or registered to HDC2500 from the MSU-
1000/1500 or RCP-1500 series.
Versatile detail control functions
Skin-tone detail function/Natural skin detail
function
Like HDC1500R, this function allows control (emphasis or
suppression) of the detail level for just a certain hue or chroma
area in the image, by creating a detail gate signal from color
components of your specified hue, such as skin tones. The
detail levels of three hues can be adjusted independently at
the same time.
HDC2500 features the natural skin detail function, which
allows for adjustment of the detail gate signal, allowing even
more vivid distinction of areas like skin that you want to make
smooth while selectively keeping areas like eyebrows that
don't require smoothing.
Detail boost-frequency control
The boost frequency can be adjusted from 20 to 30 MHz. This
allows the thickness of the detail signal to be set appropriately
for the subject, thus enabling high-definition image
expression.
H/V ratio control
The ratio between horizontal and vertical detail can be
adjusted.
