High Speed Video Developed for Frame Rates of 250,000 FPS

Scientists at Oxford University have developed a method for capturing extremely high frame rates by expanding on existing consumer-grade photography and video camera technologies. The new capture method works by using a single sensor to capture images simultaneously. According to Dr. Gil Bub,

“This is done by allowing the camera’s pixels to act as if they were part of tens, or even hundreds, of individual cameras taking pictures in rapid succession during a single normal exposure. The trick is that the pattern of pixel exposures keeps the high resolution content of the overall image, which can then be used as-is, to form a regular high-res picture, or be decoded into a high-speed movie.”

The most interesting aspect to this new development is the relatively low cost.  While the scientists developed the technology with medical and scientific applications in mind at macroscopic and microscopic levels, the underlying hardware is primarily what we use in consumer-grade cameras.  As a result, patent licensing of this tech could see future consumer applications but, obviously, at lower than the extreme frame rates required for use by the scientific community.

Panasonic Patent Reveals DSLR w/ Video Recording and Advanced Video Lenses

Panasonic DSLR with Movie Mode

Panasonic has been on a real tear lately with its solid line of Lumix Micro Four Thirds cameras, which feature interchangeable lenses. The latest two Panasonic Micro Four Thirds models, the GH1 and GF1, offer solid HD video capture.  The Panasonic GH1 comes with a 14-140mm HD lens specifically designed for quiet auto operation for use in video recording.  Currently, Panasonic has no DSLRs in its line-up.

Several recent patent applications filed in the United States Patent and Trademark Office (“USPTO”) indicate that Panasonic may be bringing some of the popular features found in the GH1 and GF1 to a full-on DSLR.  In particular, USPTO Application No. 12/581,286, filed by Panasonic on October 19, 2009, reveals a DSLR (complete with mirror and optical viewfinder) with a video mode, vari-angle LCD, on-board video LED light source and special video-compatible lenses.
