The new Phantom v642 third-generation high-speed digital camera from Vision Research can accurately colour match regular-speed broadcast cameras using new, advanced multi-matrix colour correction technology, writes David Fox. “We at Vision Research pride ourselves on responding to customer feedback. After the introduction of the v641, many customers asked for better colour-matching capability. We’ve addressed our customers’ top priority request by adding this technology to the Phantom v642,” said Patrick Ott de Vries, Broadcast Business manager for Vision Research. “With advanced Multi-Matrix Colour Correction Technology, the Phantom v642 delivers an essential tool to colour-match regular speed cameras used in live sports broadcast. This upgrade is the hallmark of the v642 and marks Vision Research’s continued interest and commitment to bringing innovation to the live sports broadcast market and to our integration partners,” such as I-Movix, LMC Live Motion Concept, and DVS. The colour correction technology allows for accurate colour matching to normal frame rate cameras, leveraging independent adjustments of saturation and hue on each of the 16 axes. The v642 is supported by a custom designed ultra-sensitive four-megapixel 2K sensor that can record full-resolution frame rates of 1,450 frames-per-second and be leveraged to support pan and zoom applications. Typical broadcast resolutions are supported, with 1080p at 2,560fps (enabling playback speeds as much as 90x times slower than live action) and 1280x720p at 5,350fps. Shutter speeds of as little as one microsecond and a global electronic shutter, produce crisp, sharp images with little or no image blur or motion artefacts. The v642 includes 8GB of built in high-speed dynamic RAM with 16GB and 32GB versions also available. It can record up to 3.7 seconds at maximum frame rate, maximum bit depth and largest resolution into the maximum internal memory, or 20 seconds at 720p. Its segmented memory feature allows users to divide images into up to 63 segments, creating multiple back-to-back shots without the need to download data from the camera. In addition, users can record into one segment while playing back a slow-motion clip from another. One segment is always recording the live action. This gives the v642 flexibility to support environments with and without playback server support. The v642 can be connected to a controller in the studio or OB truck, which can access the camera’s memory for playback while the camera operator is framing and recording the live action. It comes standard with a PL-mount for full sensor coverage (2560x1600 pixels), with native support for 1080p using customized B4 adapter options. Features include: light sensitivity of ISO 1200; two HD-SDI ports for dual-link 4:4:4 or 2x 4:2:2 (one for playback and one always live); EVS integration for camera control and playback; internal mechanical shutter for hands-free / remote black referencing; 8-bit or 12-bit pixel depth; Extreme Dynamic Range (EDR), using two different exposures within a single frame; and Burst Mode. www.visionresearch.com
