2. FEATURES
2-1 1.3 Mega pixel 3CMOS Camera
By using high-speed multi-sampling type ultrasensitive 1.3 Mega pixel 2/3 inch CMOS sensors with the three types of R,G,B,
prism it is possible to achieve color moving images of 59.54 or 50
fi elds even at night with just moonlight. This is different from a
cumulative type sensitivity increase and makes it possible to photograph even fast-moving objects without blurring.
2-2 Broadcast frame rate of 59.95 fps
The broadcast frame rate of the CMOS sensors is 59.94 fps or 50 fps. With the operating format of 1080/59.54i or 1080/50i there is
less distortion caused by rolling shutter compared to when photographing with 30 fps, thus realizing natural and smooth moving
images.
2-3 Dual Format
The image output can be switched between 1080/59.94i and 1080/50i. This makes it compatible with HDTV formats becoming
widespread not only in Japan and USA but also in Europe, China, India and Latin America.
2-4 Operates with 2/3 inch format serial digital interface lens
The lens mount conforms to BTA S-1005B, making it possible to use the wide variety of HDTV lenses and SDTV lenses on the
market. And by combining it with the lenses supporting serial digital interface, remote control Zoom/Focus is possible from an
OCP-200 control panel and other devices.
2-5 Internal filter servo
Includes internal 4-position ND fi lter wheel. When shooting outdoor pictures by daylight, inserting the appropriate ND fi lter
makes it possible to keep the iris at a good setting (not excessively closed), and thus obtain high resolution. It's also possible with
the various control panels to change the
fi lter position by remote control. What's more, during AVC (Auto Video level Control) it is
possible to automatically change the fi lter position according to the brightness of the subject.
2-6 Full Digital
■
16 bit digital output CMOS sensor
The 16 bit digital image signal is output directly from the CMOS sensor to the camera DSP. Because absolutely no analog circuits
are included in the image processing system, it's possible to obtain highly consistent and stable image.
■ Includes digital process LSI (ASIC)
Features a digital process LSI (ASIC) with an internal process (operation) of max. 38 bits, which is the same as that for Ikegami's
broadcast-use studio HDTV camera. Even non-linear processing, such as white shading correction or gamma correction, are
digitalized in the camera head to realize consistently high image quality and reliability.
■ Super KNEE
KNEE processing is carried out without changing the color phase of the highlight sections, thus reducing washed-out colors and
realizing natural highlight expression.
■ 6-axis color cor custom color effects
Features color corrector function allowing adjustment of color phase and saturation individually for the six primary colors R, G, B,
cyan, yellow and magenta. Also features a color corrector function to correct any 2 arbitrary colors of the photographic subject.
■ Scene Files
It is possible to store 8 fi les of memory the various settings for image levels, fi lters and gain set beforehand on the operation control
panel. It is then possible to recall these by pressing a single button on the control panel.
■
Engineer Setup File, Factory Setup File
It is possible to return the menu contents and all image levels and settings adjusted on the operational control panel to the default
values determined by the technical department of the user (Engineer Setup). It is also possible to return all settings to the default
values set at the time of shipment from this factory (Factory Setup File). This simpli
fi es matters if the production team changes the
camera setup or in case of maintenance when lending equipment out from a rental company. It is possible to return to either the
values of the Engineer Setup File or the Factory Setup File.
2-7 HD-SDI Output
There is dual output of HD-SDI from the camera head. The systems can independently turn the menu characters ON/OFF for each
output. If the output used for the program line is set to character OFF and the output used for monitoring is set to ON, it is possible
to operate the menu even when the camera is in operation.
