High-Quality Full-HD Pictures

Large 11.14-megapixel Image Sensor

With a large 11.14-megapixel image sensor, high sensitivity of F10/59.94 Hz, F11/50 Hz (2,000 lx) and low noise with an S/N ratio of 62 dB or higher are achieved.

Multi-format Support

Video formats such as 1080/59.94p, 50p, 59.94i, 50i and 23.98PsF* are supported for use according to the operation application.

Supported formats (when connected to AK-HCU250)

1080/59.94p 1080/50i 1080/23.98PsF*
1080/50p 1080/29.97PsF 720/59.94p
1080/59.94i 1080/25PsF 720/50p
  • * Support is planned with a software version update in the first quarter of CY2021.

B4 Mount

The 2/3 lens can be used without an external adaptor, and the internal lens is specially designed for large sensors, ensuring high video quality. This new acquisition method maximizes the effectiveness of incident light.

Built-in Optical Filter

The internal ND filter can be used in various shooting environments.

ND filters: Through, 1/4, 1/16, 1/64

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)
