UHK-430: 4K/HD Portable Camera System
Featuring native 4K 2/3-inch CMOS sensors, three chip optics, conventional B4 lens mount, and the world’s first* transmission of an uncompressed 4K signal between camera and CCU, the UHK-430 4K/HD Portable Camera System makes its debut as the first member of Ikegami’s next generation UNICAM XE camera series, developed with “no compromises” for the advent of a fully fledged 4K age.
*Note: this is the world’s first 2/3-inch 3 CMOS sensor 4K camera with uncompressed transmission of 4:4:4 4K video (as of February 16, 2016). Source: our research.
The UHK-430 utilizes three newly developed 2/3-inch 8 megapixel CMOS sensors, each capable of capturing native 4K 3840 x 2160 resolution images. It offers an excellent sensitivity of F11 (in 4K/50p) and a remarkable signal- to-noise ratio. Unlike single chip cameras or cameras using pixel-offset technology, three native 4K CMOS sensors and prism optics provide real 4K resolution, superior color reproduction and no color aliasing.
■ Next generation high speed video processor, AXII
Ikegami has developed a new processing engine, AXII, for our next generation HD, 4K and 8K format cameras. This ASIC can perform high speed processing of HD, 4K (4 x HD) and 8K (16 x HD) super high resolution video signals in various formats and frame rates. The UHK-430 utilizes these new processors that make it possible to deliver high quality, high reliability and low power consumption. The camera is also capable of 16-axis color correction and an improved focus assist function for both 4K and HD modes.
■ Equipped 2/3-inch B4 bayonet lens mount
The B4 lens mount enables the use of existing lenses. Optical characteristics such as depth-of-field will be nearly the same as 2/3-inch HD cameras. For demanding applications, such as live sports and events, 4K resolution contents can be produced just as easily as conventional HD programs.
■ Signal formats
The camera system supports as standard various video formats and frame rates, such as 3840 x 2160p, 1920 x 1080p, 1920 x 1080i and 1280 x 720p, for both 60 and 50Hz.
4K 3820x2160 59.94p,50p,29.97p,25p,24p,23.98p
HD 1920x1080 59.94p,50p
HD 1920x1080 59.94i,50i,29.97p,25p,24p,23.98p
HD 1280x720 59.94p,50p
In addition, segmented frame is supported in selected frame rates.
■ 16-axis color correction
The color matrix function enables precise color adjustment for all occasions. 16 axes of the color gamut can be fine tuned in both hue and saturation. The function works in real time and is extremely beneficial for live multi-camera applications.
■ Wide Color Space
The performance of the newly developed optical system delivers high dynamic range and a wide color space, supporting the BT.2020 color space specification in the 4K mode, and the BT. 709 color space in both 4K and HD modes.
■ Gamma Profile for High Dynamic Range
The gamma setting is selectable and can be customized to create a specifictone. The “HLG“ (Hybrid Log Gamma), which is in conformity to the international standard (ITU-R BT.2100), is pre-installed and enables more neutral image quality with high contrast for a wider dynamic range. This allows for more image information to be retained with greater headroom and color grading.
■ Ultra Wide-Bandwidth Fiber Transmission
The built-in 40Gbps optical transceiver enables transmission of full bandwidth 4K resolution video signals between the camera and the CCU. Signals include uncompressed RGB 4:4:4 video, 4 lines of return video, 2 lines of QTV video, 4channels of audio, Gigabit Ethernet trunk, etc. Due to the availability of uncompressed RGB signals at the CCU, super high quality signals for Chroma Key are created.
The UHK-430 offers the choice of three newly developed viewfinders. They apply the new Focus Assist function that supports accurate focusing in both 4K and HD modes. The digital interface allows access to the camera menu from the viewfinder. Picture-in-picture, WFM, and Vector scope functions are built into the large studio viewfinders.
