The CEL name returns to IBC this year as Cel-Soft Ltd, a recently-formed company specialising in broadcast-quality control and measurement technology. Cel-Soft is the brainchild of Robin Palmer who founded CEL-Broadcast in the early 1980s and whose design talents have been behind many innovative and successful broadcast products.
Exhibiting on stand 9.IP533, Cel-Soft will introduce the Cel-Scope3D stereoscopic analyser, a software solution to the challenges of 3D quality control and depth budget management.
"Increasing interest in stereoscopic 3D production has created an urgent need for a tool precisely tailored to checking depth budget and all possible disparities between the left and right images," Robin Palmer comments. "Pairing two television cameras to operate in 3D is easy but even slight differences in terms of physical alignment, optical and electronic performance, can seriously degrade the resultant 3D illusion. Poorly configured 3D causes eye strain and headaches or, for some viewers, destroys the 3D effect entirely. This applies to high-end rigs just as much as to semi-pro and industrial equipment. Cel-Soft has harnessed the multi-core processors and graphics cards to allow the Cel-Scope3D software package to out-perform other existing hardware solution but at much lower cost, providing real-time measurement of 3D stereo disparities in HD."
Compatible with all current versions of Microsoft Windows, Cel-Soft's Cel-Scope3D allows stereoscopic camera alignment to be performed quickly and confidently so that the 3D is accurate from the moment of capture. Running on a suitably powerful PC platform, Cel-Scope3D can display left and right channels simultaneously plus actual depth dynamics. Its display window can each be set to show the usual waveform, vectorscope and histogram graphics as well as differences in video parameters between each channel. Geometry issues can be easily identified using built-in real-time image manipulation. Quality-control tests can be performed on live stereoscopic video sources in any SD, HD or 2K format from industry standard capture cards or Firewire inputs, or alternatively from file playback.
Cel-Scope3D is designed for use both on set with live inputs and in post-production, reviewing and playing back 3D media files. Captured footage or edits in a wide range of file formats can be viewed and assessed in real time. Disparities are analysed and displayed as clear and intelligible graphics on 2D or 3D monitors. Anaglyph display, touch-screen control and auto-alarm are all supported. Displays can be scaled and arranged as six or eight windows on one or two PC monitors and also on a 3D monitor.
The most important setting the stereographer or operator has to do is to assign the target depth budget for the production in percentage of screen width or in pixels. The live 3D analysis displays then include depth analysis with depth budget markers, vertical disparity, depth histogram and vertical disparities histogram. These can be colour-coded to correspond to the false colour used on the depth map, for easy problem-area recognition. Left/right focus-difference and colour-balance-difference displays allow camera matching to be checked easily.
Each display mode is configured via a simple menu. Up to 20 configurations can be stored on preset buttons for fast recall. Embedded audio, stereo or multi-channel surround-sound can also be extracted, displayed, monitored and checked alongside the video. Logging and GPI options enable Cel-Scope3D to monitor content at any part of the 3D distribution chain.
An optional 3D recording facility allows dual stream 3D be captured direct to hard disk in a number of alternative formats.
Cel-Soft is marketing the Cel-Scope3D as a stand-alone product through independent distributors and also as a software component. Cel-Soft is licensing a number of other companies f projects and products that will be making use of the Cel-Scope3D in an embedded role. By the end of the year, Cel-Scope3D will also be available as a plug-in for one or more popular editing and grading systems.
Located in the high-tech belt surrounding Cambridge, Cel-Soft now specialises in high-performance image processing and audio software and other video, audio and other broadcast products and applications. Founded by entrepreneur and engineer Robin Palmer, the company benefits from a track record of over 25 years of successful product innovation. For more information, see www.cel-soft.com
