1. OUTLINE
The Editcam3, Model DNS-33W, is a tapeless camera-
recorder employing hard disk drives (instead of video tapes)
as a recording medium.
A compact pocket size hard disk drive package is called
FieldPak2 (FP2). Editing can be started immediately just after
mounting the FP2 to an adapter connected to "Avid Non-
linear Editing System". Moreover, newly designed circuits
make possible of compact and lightweight camera-recorder
body, without sacrificing many useful features of the Editcam
system.
The Editcam3 relieves editors of troublesome digitization
work and contributes laborsaving of operational flow from
recording to editing.
1.1 Features
1.1.1 Camera Section
■
Digital processing
Installs a 0.18
µ
m-rule digital process IC which is also
installed to Ikegami's top-class broadcast HDTV cameras.
Processes after PRE KNEE are all digitally processed;
therefore, a stable high-quality picture can be obtained.
Moreover, incorporates 12bit A/D converters to maximize the
color gradation for the darker parts of the picture while 600%
linear processing is possible in the digital process stages,
greatly improving functions such as KNEE and FLARE.
■
Analog processing
By incorporating 520,000-pixel Advanced Interline Transfer
(AIT) CCDs that have aspect ratio switching function
between 16:9/4:3, the smear level is minimized to -135 dB
even under 10,000,000x optical measurement: this result
matches that of the FIT CCD. By a new CCD signal
processing method and improvement of pre-amplifier circuit,
an S/N of 66dB (64dB for PAL) is reached, which was
impossible in conventional cameras. Moreover, employing 4
position (3200K/4300K/6300K/8000K) Electronic Color
Compensation (ECC) filters for the color temperature filters
enables to obtain the best amount of light and depth of field
since all the optical filters of DNS-33W are ND filters (4
position).
■
HYPER GAIN
The sensitivity can be increased up to +48 dB by gain up.
The minimum object illuminance of approximately 0.03 lx is
accomplished. Moreover, when an optional superhigh
sensitivity unit is attached, the sensitivity of the CCD
accumulation can be increased by 30 times for 1 second at
maximum. This superhigh sensitivity unit also enables special
effects such as mirror effect and 30p/240line.
■
Usability improvement
As a memory card function, the operation status of the
camera can be saved in the Smart Media TM . Also, the saved
data can be read to easily change the camera setup. As a
detail enhancement function exclusively for the viewfinder
(hereinafter called VF), detail is emphasized for objects in
perfect focus, so the focus can be adjusted easily (CLEAR-
VF-DTL). Moreover, installs rotary encoders enabling various
adjustment and maintenance of the camera performed at only
the camera section.
1.1.2 Body and Exterior
In addition to compactness and lightweight conventionally
asked for body of handy cameras, a design for low center of
gravity such as lowering mounting position of the lens
compared to conventional models and adoption of the large-
sized shoulder pad enables stable camera work. Moreover,
with the newly developed slide mechanism, the VF can be
adjusted by moving it forward and back, and left and right
when VF is mounted. In addition, RET switch and REC
switch are placed on the handle, and 2-pin connector for
lighting is mounted inside the front part of the handle.
1.1.3 Recorder Section
■
Color LCD with touchscreen function
By mounting a large-sized 3.5-inch color Liquid Crystal
Display (LCD), displaying various information of the recorder
section and displaying video signals are achieved. This color
LCD has a touchscreen function. By touching buttons
displayed on the screen, settings of the recorder section can
easily be modified. Mode can be changed easily from
information display to video display by pressing the SHIFT
key in the control switch panel and lightly touching the
screen.
■
Recording format
JFIF and DV25 are supported by default as recording
formats. In addition, DV50 and MPEG can be added
optionally.
■
40GB FieldPak2
For recording medium, FP2 with 40GB hard disk is included
as standard equipment. When DV25 format is used, recording
time can be approximately 180 minutes. Recording time
depends on the recording format.
■
Input and output
Not only camera images but also, as an option, images input from
external equipment (analog composite) can be recorded. In addition,
SDI video output and IEEE1394 output are possible optionally.
