Various Functions and Versatile Interfaces

High-speed Scanning for Low-skew Shooting

The AK-HC3900GJ/HC3900GSJ supports a high reading speed of 1/100 of a second, compared to 1/60 of a second on standard cameras. The skewing characteristic of MOS sensors has been reduced by reading out the MOS sensor signal at high speed.

Digital Extender (2x)

Video image size is doubled by the digital signal processing circuit, enabling high-magnification shooting even with low-magnification lenses. Sufficient resolution is maintained even when the image is magnified and the light reduction seen with extender lenses is prevented.

Chromatic Aberration Compensation (CAC)

This exclusive technology utilizes communication between the lens and camera to deploy a sophisticated algorithm that automatically compensates for registration errors caused by lens chromatic aberration and minimizes the circumjacent blur.

Focus Assist Functions

Quick and accurate focusing is supported with focus assist functions such as Focus Bar (indicates focus level), Focus-in-Red (uses color to indicate areas in focus), MAG (magnifies central portion), and Square (shows focus status of screen as a whole). Lenses with auto focus and focus assist capabilities are also supported*. The Remote Operation Panel (ROP) can also be used to focus and zoom while using the digital lens.

Flash Band Correction

The problem of flash bands (a phenomenon whereby dark and light areas are produced in the same frame when the flash is released) is resolved by the high-precision flash band detection and correction of the camera signal processing LSI.

Diverse Color Correction Functions

Users can perform 12-pole color correction and individual adjustment of saturation and hue with a linear matrix. In addition, the separate skin color adjustment function (Skin Correction) enables more fine-tuned color expression.

Skin Tone Detail Correction

Tone down wrinkles and blemishes in on air personalities to beautifully shoot natural skin tones. Not limited to skin tones, this correction feature can be applied to any hue phase and can define three independent tone ranges for correction. A function to select and directly adjust a specific color is also included.

Shockless Gain

It is possible to smoothly transition the image changes that occur when the gain is changed. In addition, with the 0.1 dB step master gain adjustment function, you can fine tune the adjustments to match the scene being shot.

Camera Standalone Output Formats

For camera head output (HD-SDI 1/HD-SDI 2), it is possible to select 1080p, 1080i, and 720p.

Long-distance Transmission

Long-distance transmission of uncompressed video signals to the Camera Control Unit (CCU) via optical fiber is supported. Transmission of approximately 1.2 km is possible when power is supplied to the camera from the CCU. In addition, the transmission distance can be extended up to 10 km by using an external power supply for the camera and general-purpose optical transmission equipment*. In addition to a dedicated serial line, IP connection via LAN cable is also supported for control between the CCU and the Remote Operation Panel (ROP).

  • * If the transmission distance is extended by connecting fibers at multiple points, the distance will be reduced due to signal attenuation. Use of repeaters as appropriate is also recommended.

Detailed Functions Optimized for Operability

  • Color temperature display and adjustment function (2000 K to 15000 K variable).
  • Camera settings, such as video adjustments, can be saved to an SD memory card. Firmware version upgrades are also supported.
  • The lens file function enables flare and shading values to be saved.
  • Support for IP control.
  • There are three user buttons enabling function selection on the camera head, with four on the AK-HVF100GJ LCD viewfinder and three on the AK-HVF75GJ LCD viewfinder.
  • One intercom line can be connected.

Video Transmission (TRUNK) functions

Video signals other than those from this unit can be transmitted between the camera and CCU using only an optical cable, enabling the system to be upgraded according to the operating conditions.

  • H3G/1.5G-SDI (CCU->camera) one line (Internal FS):
    This line can be used for monitoring (studio floor monitor) with a prompter or camera, etc.
  • 3G/1.5G-SDI (camera->CCU) one line (Internal FS):
    This line can be used to output video from a handheld or PTZ Camera in the studio or the field, etc. to the CCU (system). Since the camera video input is equipped with a frame synchronizer, asynchronous video signals can also be used.

4K Upgrade Support

Supported formats with 4K upgrade (when connected to AK-HCU250)

2160/59.94p 2160/25p 2160/25PsF
2160/50p 2160/23.98p 2160/23.98PsF
2160/29.97p 2160/29.97PsF
  • *1: An optional 4K/12G-SDI Interface Kit AK-HUC01 (sold separately) is required. See the page for more information.
  • *2: Supported when connected to AK-HCU250PJ/HCU250EJ/HCU250PSJ/HCU250ESJ/HCU250PTJ.

ST 2110 Upgrade Support without CCU

SMPTE ST 2110 Support

Support for connection with the SMPTE ST 2110 in studio cameras was previously done via CCU, but the AK-SFC391* software key (sold separately) enables SMPTE ST 2110 connection.

This allows the AK-HC3900GJ/HC3900GSJ to transmit broadcast-grade uncompressed HD video directly from the camera body over IP with low latency, without the need for a CCU. It also supports IP return video (HD), reference signal (PTP), TRUNK signal output (HD), prompter input, and IP intercom audio input/output with the ST 2110.

Space-saving and Compatibility with the IT/IP platform "KAIROS"

With this upgrade, it is also possible to connect to the IT/IP platform "KAIROS" via IP network. Unlike conventional M/E switchers with dedicated hardware configurations, KAIROS is a software-based live video platform that uses our proprietary video processing technology that utilizes GPUs to enable low latency, high quality video to be multiplexed as much as GPU power allows. When connected to the ST 2110 (1080p), a single mainframe AT-KC2000 can have up to 32 inputs and 40 outputs* simultaneously. Furthermore, the CCU-less connection of the AK-HC3900GJ/HC3900GSJ HD studio camera eliminates the need for CCUs, which are required for the number of cameras in a conventional baseband system, further saving space and wires for highly efficient operation.

Power-Saving for a Sustainable Future

Panasonic Connect is implementing Green Factory measures at all of its global manufacturing sites with the aim of reducing its impact on the environment by continuously reducing CO2 emissions, waste, water usage, and chemical substance emissions. We also carry out environmental assessments on our products starting from the planning and design stages, and strive to develop Green Products with enhanced environmental performance.
The AK-HC3900GJ/HC3900GSJ HD studio camera, which was born from these efforts, can significantly* reduce power consumption compared to conventional systems during multi-camera operation by eliminating the need for a CCU through this upgrade.

  • * 60% reduction compared to conventional products. Comparison with conventional system configuration (using the AK-HC3900 studio camera and AK-UCU250 CCU).
