Overview
This new-generation all-format HD camera is designed to support the 720P format.
By way of providing support for the 720P format, this model uses newly developed 2/3
z
CCDs with a million
pixels [1280 (H) x 720 (V)]. By taking a fresh approach to the on-chip lens, CCD structure and processes, these
new CCDs embody dramatically improved sensitivity, smear and dynamic range specifications compared with
conventional CCDs, and they achieve a high performance which is on a par with that of SD. Furthermore, the
moire in the band has been slashed by offsetting the pixels by combining Panasonic’s unique horizontal line
readout CCDs with high-accuracy signal processing.
The newly developed digital signal processing LSI which supports 12-bit A/D conversion and which is provided in
the camera head processes the gamma, knee, detail, matrix and other process signals and uses a new system
for CCD defect correction to achieve improved operability with a greater number of functions, high quality and
high stability which only digital systems can deliver. The 12-bit A/D converter yields a stable wide dynamic
circuit with a high signal-to-noise ratio from the dark areas to the highlights.
A newly developed casing is used to house the Multi-Format Camera head to achieve a compact size and light
weight. The amount of heat generated has been significantly reduced by designing the new circuitry to consume
less power and by adopting an efficient heat dissipation design for the new casing.
SD signals (D1, VBS) can be output and RET images and PROMPT signals can be input by connecting the
Multi-Format Camera to the CCU (AK-HCU931P, optional accessory).
In terms of controlling the camera’s functions, the ROP (AK-HRP931P) or MSU (AK-MSU930P), also available
as an optional accessory, can be connected to the CCU to control such analog functions as the camera head’s
pedestal and iris and control such switches as the gain and output selector switches.
Features
Newly developed 720P, 2/3
z
million-pixel CCDs
incorporated
≥
This achieves a high sensitivity that surpasses the
standard sensitivity of F10 and is on a par with SD.
≥
Smear has been cut to 130 dB and the number of white
marks has been drastically reduced by process
improvements.
≥
H-CCD drive is accomplished at a frequency of 74 MHz
to attain a high response and high resolution.
Digital signal processing LSI with high picture quality
featured in the camera unit
≥
After the process circuits, the signals undergo 12-bit, 74
MHz high-picture-quality digital processing, yielding a
high reliability, more functions and enhanced operating
ease as a result.
Multi-functional enhancer
≥
In addition to the many functions such as chroma DTL,
skin DTL and dynamic DTL, there is a choice of 8 boost
frequencies. (For both HD and SD)
Designed to achieve low noise levels of below NC15
≥
The fan mode can be switched to suit the application at
hand, and measures to reduce the power requirements
and improve the heat dissipation were adopted in the
final design.
Fuller complement of control circuits and auto setup
(ASU) function
≥
The self-diagnosis functions have been enhanced, and it
has now become possible to select the ASU function by
combining the external shooting chart and internal test
signals as well as the normal, simplified or other mode.
Peripheral components
≥
Ease of operation can be further improved by configuring
a system where the Multi-Format Camera is used in
combination with the remote operation panel (ROP) and
master setup unit (MSU).
≥
Using the ROP matrix, for instance, ROP assignment is
enabled without connector patch switching.
Data trunk function
≥
Two RS-422 circuits are provided as a standard feature.
They obviate the need for the cables used with virtual
control, pan-tilt head and lens control, etc.
D/C output of camera supported (optional function)
≥
The VF output or camera output can be selected as the
D/C output.
≥
The VF images can be monitored on the NTSC LCD
monitor.
