State-of-the-Art 16-bit Full Digital HDTV Camera System

HDK-790GX

State-of-the-Art 16-bit Full Digital HDTV Camera System

The HDK-790GX are high quality multi-purpose high end camera models reproducing the quality of Ikegami’s EX-series cameras, and adding new features and accessories associated with the new Unicam HD series.They can be used for studio, as well as, field applications.

2/3-inch 2.3 Mega pixel AIT CCDs

Three 2/3-inch 2.3 Mega pixel AIT CCDs are employed to achieve 1000 TVL horizontal resolution with high signal to noise ratio of 61dB at F10 (1080/59.94i) or F11 (1080/50i) sensitivity.

Video processing technology to maximize the benefit of 16-bits

This camera is designed from the start based on 16-bit A/D and matching 16-bit DSP to maximize the benefits of high bit quantization. Especially for the dark areas of the picture, the higher gradation for gamma and other circuits improves the reproduction, providing for more natural color in the shadow areas of the picture.

Digital Extender

There is the selection of x1.5, x2, x3, x4 digital extender available to enlarge the image at the center of shot without any loss in image sensitivity. * It will reduce the resolution of the image.

2 Channels QTV

Two channels of QTV output (VBS) are available at the camera for prompter and external monitoring purposes. * BS/CCU should support 2 channels of QTV.

Built-in Triple Layer Filter (ND/EFF/ECC)

The triple layer filter system can be remotely controlled from OCP/MCP. The three layers are ND (100%, 25%, 6.2%, 1.6%), EFFECT (Clear, Cross, Snow, Fog) and Electronic Color Compensation (ECC: 3200K/4300K/ 5600K/6300K/8000K).In addition, there is Variable Color Temp. function that enables the camera operator to continuously vary the color temperature from 2,000k to 20,000k for easy and precise adjustment.

Moire Reduction Filter (Factory Option)

An Anti-Moire Optical Low-Pass Filter can be fitted in the filter wheel to reduce unwanted moire video patterns when shooting a large LED screen, etc.

Newly developed FPGA with advanced full digital process ASIC

The HDK-790GX incorporates a newly developed FPGA together with advanced full digital process ASIC to achieve outstanding picture performance.

Advanced features made possible with digital technology

Advanced features such as Master Gain Control, Variable Color Temp., Custom Gamma functions are incorporated.

Lens Aberration Correction Function

The Lens Aberration Correction Function is newly incorporated for minimizing the loss of resolution and colored edges caused mainly by lens chromatic aberration.

HD SDI Trunk

When the camera is operating with CCU-970M, the system allows 3G (1.5G x2) transmission from the camera head to the CCU, and a second 1.5G video can be transmitted to the CCU as a video trunk channel.

Camera Operator Assist Functions

There are two types of camera operator assist functions incorporated in the HDK-790GX camera head.The viewfinder detail(VF DTL) function allows the camera operator to increase the detail edges to the viewfinder video for easy-focusing. In addition, the Quick EZ Focus (Focus Assist) function is a newly incorporated useful tool, providing very distinct enhancement to the viewfinder signal to enable the camera operator to make critical focus adjustment.
