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.

HDK-790E/79E is designed as a Multi-use Camera to meet the format requirements of HDTV (1080i/720p) and SDTV (480i/480p). The CCD read out can be switched between interlace and progressive scan modes. The signal can be converted in the CCU to different formats.

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 micro m ASICs into 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.)

The CB-79HD/TA-79HD HDTV new triax adaptor system is a higher performance. It is ideally suited for various field applications in the digital era. The system consists of the TA-79HD docking Triax Adaptor and the CB-79HD CCU side Converter Box. The CCU converter box enables use of triax or fiber cable without any reconfiguration. Docking type adaptors for triax or fiber make camera configuration quick and easy. No local AC power is necessary because the CCU provides AC power for the full system. The CB-79HD CCU converter box is only 1U rack size providing efficient use of space.

12bit Full Digital

Using newly developed full digital process Ics, precision designed at 0.18 micro m rule, the video signals are digitalized with 12-bit A/D conversion and up to 38-bit internal digital processing (quantization) circuits.

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.

With Independent DTL system in the CCU, the type and amount of compensation can be optimized for the different requirements of HDTV and SDTV. Sophisticated features made Possible with digital technologies.

Includes a color correction function that enables hue and saturation to be adjusted for each 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.

Improved sensuous expressions such as texture and sheen, and richer reproduction of details in skin tone in dark backgrounds.

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.

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 edging gives the impression that fine parts of subjects or high frequency images have a higher resolution.

The portable and studio cameras use the same CCD, same analog and digital video processing, same optical filters, and in most cases, the same PC boards, providing an unparalleled similarly in performance and function between the two camera types.

HD SDI output is provided from the camera head, and by using VTR connector (option), direct connection is possible with HD digital equipment, such as an HD VTR.

The CCU-790 accepts two channels of return video input as standard. It is available with up to 4ch as a factory option; Input signals can be selected from HD-SDI, D1 component and D2 composite signals. The CCU includes an up converter permitting an SDTV return video signal (D1 & D2) to be viewed on the HD viewfinder. The CCU transmits the HD return video signal (each Y, Pb, Pr) and two NTSC Q-TV video signals (Q-TV1*, Q-TV2*) to the camera for teleprompter and external monitoring purposes. *For the HDK-79E, either Q-TV1 or Q-TV2 can be selected for output.

For the HDK-79E, a 2-inch 16:9 high resolution VF for portable application and a 5-inch B/W VF (option) for studio application are available. Employing a magnifying eye-piece in the 2-inch VF, visibility is further improved. For the HDK-790E, 7" B/W VF and 7" color VF (option) are available. 7-inch VF attaches to the camera with a mechanism allowing easy panning and tilting for VF. Cable connection between the camera and the 7-inch VF is integrated into the pan and tilt mechanism and fully protected against possible damage ., In addition, a 6-inch color LCD viewfinder is also available as an option for both studio and portable camera models.

Both the studio and portable cameras are compact with low center-of - gravity. Especially for the portable camera there is excellent balance when operated on the shoulder. Regarding the 7-inch viewfinder for HDK-790E, the position is lower and closer to the optical axis of the camera head.

A Return select switch is located on the handle grip of the portable camera to control the selection when the camera is held off the shoulder, such as on the hip for low angle shots.

An On-line Diagnostic System monitors a range of circuits including video, control, fiber optic transmission, pulse and power supply.

The camera incorporates the HDTV lens mount (BTA S-1005B type) as standard. But the Ikegami 2/3-inch lens mount can be specified as a factory order option to use lenses from conventional NTSC Ikegami HK- series cameras such as HK-388/377/366/355, etc.

The SMPTE standard fiber camera cable connector is provided with a pivoting mount on both the portable and studio camera heads. This permits a natural bend to the cable, even for example, when the portable camera is placed on the ground.

HDK-790E has its side handle directly attached to the camera head, which ensures the solid structure of the handle. It also has a loop to attach a rope, by which the camera head can be hoisted.
