Overview
The HDC2500, HDC2400, HDC2570 and HDC2550 are 2/3-
type high-definition portable video cameras equipped with
CCD for 2,200,000 pixels.
The differences among the models are shown below:
* 2× slow motion format.
Features
High picture quality and high performance
HDC2400/2500/2570/2550 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 6).
Digital extender function
The central part of the viewfinder picture is digitally magnified
to twice its size.
The digital extender function prevents the decrease in
sensitivity (F-drop) that occurs when the lens extender
function is used.
Note
This function does not operate when a 2x slow motion format
is selected.
This function also reduces the resolution of images to one-
half.
Aberration correction function
This camera features ALAC 2.0 (Auto Lens Aberration
Compensation).
When an achromatic lens is used, this function reduces
chromatic aberration of magnification automatically.
For details on achromatic lenses, contact a Sony sales
representative or Sony service representative.
Standard 3G optical digital transmission unit
(HDC2500/2400)
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-59.94P 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-
59.94i and 720/50P-59.94P operation
• Dual camera system for transmitting video signals from two
HDC2500/2400 cameras to two CCUs using just one optical
fiber/multi-cable
• Subcamera system for transmitting video signals from both
an HDC2500/2400 and another subcamera-such as the
HDC2500
HDC2400
HDC2570
HDC2550
