Ikegami designs 4K cameras for content creators
Developed from Ikegami's high-definition HDL-F3000, the UHL-F4000 has been designed for content creators seeking to future-proof their work by mastering in 4K. Capable of delivering HD cut-out images in addition to 2160p59.94 or 50Hz 4K, the image sensor unit uses three CMOS global shutter elements to ensure no rolling shutter distortion, even in aerial imaging applications where subjects are constantly moving in parallel.
Measuring 100mm x 128mm x 90mm (WxHxD) and weighing 1.1kg, the UHL-F4000’s digital zoom is capable of magnifying from 1.01x to 10.0x, including gradual acceleration. A focus-assist function places the edge components of the 4K image on the high-definition monitor output feed. Further refinements include a variable contrast control that can be used during reduced visibility such as fog or smoke. When shooting at night, the camera can be adjusted for optimum noise reduction with high gain, while a vertical image reversal mode allows upside-down mounting.
Aberration correction can be performed using data from the lens servo block, even if the servo block is removed from the lens to be used in the limited space of a gimbal. The camera head consumes very low power as all video processing is performed in a separate base station. A 40Gbps duplex optical fibre connection communicates between the camera head and base station for positioning up to 10km apart. The optical fibre can be integrated into one bidirectional core via an optical circulator and passed through a single-core optical rotary joint used for a small gimbal.
The BSX-100 is a 3G fibre base station offering a coherent upgrade path for users as they progress from SDI to IP, from SDR to HDR and from HD into HD/4K dual-format workflows. Designed to be fully compatible with Ikegami Unicam HD system cameras, including the HDK-99 and HDK-73 models, the base station provides 3G-SDI/HD-SDI HD output.
SMPTE ST 2110 media-over-IP interfacing is available as an option for use across 10GbE and 25GbE networks, in addition to a 4K output software key allowing use of HD cameras in a variety of configurations, including simultaneous production in HD and 4K resolutions. Complementary 12G-SDI/3G-SDI quad link interfaces are also available. Housed in a 3U, half-rack, low-mass unit, the base station optionally includes HDR to SDR conversion.
