Digital Processing Camera Control Unit, the CCU-790A
The Ikegami HDK-series HDTV cameras are designed as Multi-Use Cameras to meet the format requirements of HDTV and
SDTV, incorporating next-generation 0.18um ASICs in the Camera Control Unit, the CCU-790A.
Also using advanced conversion ASICs, an Optional Engine Board has been developed to achieve Frame and Multi-Format
Conversion. (24p, 30p, 720p, 1080i, etc).
Incorporating a next-generation digital process ASIC
Using a full digital process ASIC (Application Specific Integrated Circuit), precision designed at
0.18um rule, the video signals are digitalized with 12-bit A/D conversion and up to 38-bit internal
digital processing (quantization).
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.

Engine Board (option)
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.
