New DSP with 14-bit Full Digital
Incorporating advanced full digital process ASIC, 0.18um design rule.
Using sophisticated full digital process ICs, precision designed at 0.18um rule, the video signals are
digitized with 14-bit A/D conversion and up to 38-bit internal digital processing circuits.
The latest 14-bit A/D conversion
14-bit A/D converters maximize the color gradation for the darker parts of the picture, providing a
high-level of digital signal process capability. It preserves fine gradation and details when reproducing
the dark areas of the picture.
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 systems in the CCU, the type and amount of compensation can be optimized for the different requirements of HDTV and SDTV.
Digital Processing Camera Control Unit, the CCU-790A
DTV Multi-format

CCU-790A Front Panel
Sophisticated features made possible with digital technologies
FINE DTL function
By expanding the small edge in the low constrast object and compressing the edge
component in the high contrast object, the impression for the glare of picture with
too much edge is reduced and the natural image, which is more visual for human
being, can be obtained.
Six-Vector Color Corrector + Two-Axis Custom Color
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. Color correction before
Gamma Circuit provides more true color reproduction.
Enhanced Digital DTL
Improved visual reproduction of subjects such as texture and sheen, and richer
reproduction of details in skin tone and in dark backgrounds is realized.
Super KNEE
The Super Color Knee system maintains color saturation without changing the hue
of the highlighted parts and provides natural color reproduction under high
luminance conditions.
CCU-790A Rear Panel
KNEE DTL function
