New Camera Control Unit, the CCU-790A
The Ikegami HDK-series HDTV cameras are designed as a Multi-Use Camera to meet the format requirements of HDTV and
SDTV have incorporated next-generation 0.18
µ
m ASICs into a new Camera Control Unit, the CCU-790A.
Also using newly developed ASICs, an Optional Engine Board has been developed to achieve Frame and Multi-Format
Conversion. (24p, 30p, 50p, 720p, 1080i, 480i etc)
Incorporating a new, next-generation digital process ASIC
Using newly developed full digital process ICs, precision designed at 0.18
µ
m rule, the video
signals are digitalized with 12-bit A/D conversion and up to 38-bit internal digital processing
(quantization) circuits.
DTL Correction
A detail correction system, including digitally processed horizontal, vertical and diagonal correction
signal for red, green and blue video, is incorporated into the camera head, and obtains noise-free full
resolution HDTV picture quality even if the camera is used in stand-alone configuration.
Independent DTL
With Independent DTL system in the CCU, the type and amount of compensation can be
optimized for the different requirements of HDTV and SDTV.

Six-axis + Two-axis Color Corrector
Includes a color correction function that enables hue and saturation to
be adjusted for each of the six primary colors (R, G, B, Cy, Y, Mg),
plus another function to make color correction of two user-selected
colors of the subject.
Enhanced Digital DTL
Improved sensuous expressions such as texture and sheen, and
richer reproduction of details in skin tone in dark backgrounds.
Super KNEE
The Knee system makes corrections without
changing the hue of the highlighted parts
and produces a more natural highlight
appearance, rather than washing it out.
Clear VF DTL function
This function makes a difference in the edging of
the image exclusively in the viewfinder, to make the
precise point of focus easier to find, and to make it
easier for the cameraperson to focus.
Wide-band DTL function
Wide-band edging gives the impression that fine
parts of subjects or high frequency images have a
higher resolution.
Evolutionary New Features /
Designed for DTV
2/3-inch 2,200,000-pixel FIT CCDs
2/3-inch 2,200,000-pixel 1080i FIT CCD image sensors are employed to achieve superb picture quality with a horizontal resolution
of 1,000 lines and a S/N ratio of 56dB.
Simulcast (High-end HDTV and NTSC Camera)
Using a down converter incorporated in the CCU as standard, the HDK-790E/79E can be operated as a high-end NTSC studio
camera. A high sampling frequency of 28.64MHz achieves maximum resolution of 900 TV lines in the NTSC format. Both HDTV
video and SDTV (NTSC) are provided simultaneously from the CCU and in both digital and analog form. Monitoring video signals
(WFM and PM) are likewise provided in both HDTV and SDTV to adapt to different system installations and to permit continued use
of conventional monitoring.
