Hacked camera captures high-speed video

Gil Bub and Peter Kohl, physiologists at England's University of Oxford, used a normal, off-the-shelf digicam and a home cinema projector to conceive a high-speed image capture device that records still and moving images simultaneously.

The duo came up with this idea when they encountered problems aligning their high-speed videos and still pictures, taken with independent cameras, of a rat's heart muscle cells. They disassembled the projector and removed the micro mirror component, fixing it between the lens and imaging sensor of a typical camera.

The result: A budget high-speed 400fps camera that Bub said can deliver higher-resolution … Read more

Casio goes high-speed with its pocket megazoom

The Exilim EX-FH100 is very similar to 2009's FC100 in features, but out front is a 24mm-equivalent lens with a 10x zoom range. Essentially it's a marriage of the FC100 and Casio's H10. But that's not the whole story.

The FH100 features a high-speed back-illuminated 10.1-megapixel CMOS sensor (the FC100's wasn't backlit). The back illumination improves overall sensitivity, which should reduce noise levels in low-light photos. The speed of the sensor helps it shoot up to 30, 9-megapixel images at 40fps. It also enables up to 1,000fps high-speed movie recording, though at … Read more

Casio FH20: It's all about the high speed

This is a test clip of some birds that I took using the Casio Exilim EX-FH20's high-speed video capture. (I know it's not the most exciting clip in the world, unless you're into watching 6 minutes of birds bathing in public, you sicko.) This feature is really pretty cool (as is the camera's 40-frame-per-second shooting speed), though I'm still on the fence about how much someone would actually use it after the initial "wow, this is cool" phase.

But Casio deserves credit for pulling off the high-speed shooting features on the Exilim EX-FH20 … Read more
