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.
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)
- * Support is planned with a software version update in the first quarter of CY2021.
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
HDR (High Dynamic Range)
This mode provides rich gradation to render contrast, color and shadow in highlights and dark image areas that could not previously be reproduced due to overexposure and black defects respectively, resulting in more realistic image quality. Variable HDR that makes optimal adjustments for a wide dynamic range is supported. In addition, it is possible to configure a system supporting simultaneous HDR/SDR in order to handle production environments with both. The SDR signal can suppress blown-out highlights with the offset gain function from the HDR, and the same knee adjustment as for HDR can be performed for highlights.
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.

Standard camera (1/60 sec.)
AK-HC3900 (1/100 sec.)
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.
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 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
4K Upgrade Support*1
4K video output with horizontal and vertical resolution of 2,000 TV lines can be achieved with the optional 4K upgrade. 4K/HDR and ITU-R BT.2020 are also supported, enabling higher luminance and a wider range of color expression. A range of output interfaces, including 12G-SDI*2 and 3G-SDI QuadLink*2, are also supported for improved operability during 4K video production.
Supported formats with 4K upgrade (when connected to AK-HCU250)
- *1: Support planned in the second quarter of CY2021.
- *2: Supported when connected to AK-HCU250PJ/HCU250EJ/HCU250PSJ/HCU250ESJ.
ITU-R BT.709 is supported in HD mode and ITU-R BT.2020 is supported in 4K mode. This camera is compatible with BT.2020, a color space that can recreate almost every color in the natural world, enabling visual expression with excellent color reproduction.
- * Support is planned with a software version update (4K Upgrade) in the second quarter of CY2021.
