The Ikegami HDK-79GX (FA-55) is a high-definition camera system designed for professional broadcast applications, offering high-quality imaging, advanced processing techniques, and versatile operational capabilities. It is built to support various shooting styles, from stand-alone VTR location shooting to full studio and field productions when integrated with peripheral equipment like the BSF-55 base station.
Function Description:
The HDK-79GX employs a 2.3-million pixel 2/3-inch AIT type 1080i CCD as its image sensor, delivering superb picture quality with a horizontal resolution of 1,000 TV lines and an S/N ratio of more than 60dB. Its newly developed digital process IC, featuring 16-bit A/D conversion, digitizes video signals and performs non-linear image processing for white shading and gamma correction, ensuring high-quality pictures, advanced functions, and stable reliability.
The camera system supports various picture expressions through several integrated functions:
- DTL Correction: Includes horizontal and vertical DTL correction circuits that independently process red, green, and blue video signals digitally. This allows for full-resolution HDTV picture quality with minimal noise, even in stand-alone VTR shooting.
- Wideband Digital DTL: An advanced digital DTL circuit enhances texture and sheen reproduction, improving detail in dark backgrounds and skin tones with reduced noise.
- Focus Assist Function: Provides a focus assist area in the viewfinder image to help the cameraman achieve precise focus. This area is displayed during focusing triggered by the lens focus ring or focus switch operation.
- Six-axis + Two-axis Color Corrector: Allows for hue and saturation adjustment of six primary colors (R, G, B, cyan, yellow, magenta), and also includes a color corrector for two selected colors.
- Super KNEE: This function produces KNEE processing with less saturation loss and preserves the hue of highlighted parts, resulting in a more natural highlight appearance without washing out colors.
The HDK-79GX is designed for superb operation and ease of use, featuring:
- Application of Conventional Standard 2/3-inch Lenses: Uses the BTA S-1005B lens mount, allowing compatibility with both HD and SDTV camera lenses.
- High Performance Viewfinders: Supports various viewfinder options, including a standard 2-inch B/W viewfinder with a magnifying eyepiece for fine detail visibility, an optional 2-inch color viewfinder, a 5-inch high-precision B/W viewfinder, or a 9-inch liquid crystal color viewfinder.
- Low Center of Gravity, Light Weight, and Excellent Balance: Engineered for optimal balance during shoulder-mounted shooting and at various angles.
- On-Line Diagnostics: An integrated system monitors the status of circuits, including video, control, fiber optic transmission, pulses, and power supply, providing real-time status information.
- Rotating Camera Cable Connection: Features a rotating fiber camera cable connector, facilitating studio and field shooting at different angles.
- Return Switch: A switch on the handle grip allows easy switching between RET-1 and RET-2 images, useful for low-angle shooting.
The camera is equipped with various interfaces:
- HD-SDI Signal Output: Provides HD-SDI signal output, usable as the main line signal in self-contained mode or as a monitor output when connected to a BS.
- Return Video Interface: Supports return video in HD-SDI signal form (RET HD-SDI signal transmission).
- Data Trunk Channel (RS-422): Available for virtual studio applications when connected to the BSF-55.
