Various fundamental performance'parameters have been emphasized to achieve the superior performance desired by
today's program originators.
Standard sensitivity is 2000 lux @ f/5.0. Maximum sensitivity at + 18dB video gain is 20 lux @ f/1.4 (using 89.9% reflectance chart).
-59dB is achieved with low input capacitance tubes using conventional measuring techniques (0dB video gain).
Deviation of RED and BLUE with respect to GREEN is within 0.05% in Zone 1,0.1 % in Zone 2, and 0.3% outside of
Zone 2 as a result of the Quadrant Geometry Correction circuit used.
By operating the pick-up tube in a high voltage mode, center resolution of 650TVL limiting and comer resolution of
500TVL limiting is achieved (using Diode Gun pick-up tubes, measured at 2000 lux illumination on a standard RETMA
Crisp, high contrast pictures are assured by the use of an improved cathode-ray tube.
Output Signal Characterlistics
In accordance with EIA Standard RS-170A, blanking pulse widths and SC-H phase relationship adjustable.
Up to 10 volts per meter (140dB) from 100KHz to 600MHz
for the entire camera surface (not including lens port) .
Chroma Aperture Correction
Generates aperture correction signal when GREEN information is absent from the signal, results in improved sharpness of
picture in RED and BLUE content areas.
Parabolic modulation of electrostatic focus voltage improves comer resolution.
Dynamic DetaU Correction
Parabolic modulation of detail correction signal improves corner picture sharpness.
Knee Apertnre Correction
Expands horizontal video frequency response in highlight areas of picture to compensate for aperture correction fall-off
due to gamma compression of correction signal.
The HL- 79E is provided with all the elements necessary to support the sophisticated user operationally:
Selectable White Balance Corrections
Two automatically set and one manually preset positions are available. Inadvertent operation of the auto-set push button is
prevented by a protective cover. Automatically set corrections are retained indefinitely by digital memory.
Auto Black Balance
Rapidly corrects individual channel black level to assure correct colorimetry.
Auto Highlight Compression
Permits accommodation of scenes with wide dynamic range by automatically adjusting artificial knee slope as a function of
Dual Concentric Rlter Wheel
Separate concentric filter wheels, each with 3 positions, are
provided for color temperature compensation and scene illumination level correction. The entire filter wheel assembly is
easily removable to facilitate the cleaning and replacement of individual filters.
Selectable Video Gain
Normally 0/ +9dB/ +18dB, the gain modes can be internally
adjusted to 0/ +6dB/ +12dB, 0/ +6dB/ +15dB or 0/ +9dB/ +15dB to suit user requirements.
SC / H Phase Adjustment
Permits precise adjustment of the time relationship between color subcarrier and horizontal sync to assure proper tape
Adjustable Blanking Widths
To compensate for errors introduced into the recorded video signal by the recording/time base correction/editing process,
both horizontal blanking width and vertical blanking width have been made adjustable over a wide range.
Numerous readouts available to assist the camera operator:
White Balance Mode (A, B, Preset)|
Auto White Balance
Auto Black Balance
Video Level (Zebra)|
Lens Extender ON
Individual R, G, B Outputs at standard level and impedance are available from the camera.
Color Bar Signal
Color Bars include split white with 75% and 100% white as well as six (6) hues; black, I and Q for VTR and color
Synchronization to external signal sources (composite color or Black Burst Signal) is possible. Individual horizontal pulse
timing and subcarrier phase adjustments are available to facilitate proper timing of the camera's Video Output Signal.
The HL-79E is a fully automatic camera configured to permit the camera operator to concentrate on artistic aspects with
minimum attention required by the camera operators. The automatic features provided are:
Auto Iris Control|
Auto White Balance (2 Modes)
Auto Black Balance
Auto Iris Closure
Auto Iris Waiting|
Auto Highlight Compression
Auto beam control
To simplify maintenance of the HL-79E numerous features have been incorporated in the design:
