AlphaEye

What it does:
  • Provides lens distortion and perspective correction for any type of lens
  • Supports HD resolution- 1080i, 1080P, 720P
  • Inputs: 1x 3G HD SDI, 1x Genlock, Fibre. HDVI
  • Dual link support
  • Outputs: 2 3G HD SDI, Fibre, HDVI
  • PC based UI for set up
  • Enables use of low cost small cameras for Broadcast use

The use of small broadcast quality HD cameras with wide angle or fisheye lenses have become increasingly prevalent in live broadcast applications such as sport, ENG, wildlife programming, and RealityTV, with non-broadcast use in medical, forensics/security and online gaming. For creative as well as other considerations, lens distortion and curvilinear perspective errors arising from the use of these camera lenses and camera positioning can produce results which can be considered undesirable and require correction. For live image feeds, rendered software based offline processing is not possible. AlphaEye addresses the problem directly through a hardware based sub pixel geometry engine that can correct for lens distortion in realtime. The corrected output exhibits no visible artefacts at all operational HD resolutions and is suitable for all high bar broadcast applications.

System Configuration

The AlphaEye does not require co-location to the camera source. The unit can be located remotely via industry standard 3G co-axial cable subject to commensurate distance limits, but optionally supports fibre connections up to and beyond distances of 1000 metres. Additionally, the unit has a Genlock input removing the need for external Genlock/Synchroniser hardware.

PC/MAC based UI

Alpha Eye UI

Configuration requires the one time connection via USB of the AlphaEye unit to a Mac or Windows laptop or hand held Windows based Microsoft Surface Tablet to set up and save the correction parameters of the distorted image source feed. Once configured, the set up is saved to the AlphaEye unit, and the external USB laptop/tablet device can be disconnected.
