  • The Timing of Blinks

    Update 11/3/2009: RadioLab did a short piece in October on this phenomenon, even discussing the Mr. Bean test with the Japanese researchers: http://blogs.wnyc.org/radiolab/2009/10/05/blink/

    ———-

    From recent research out of Japan: “The results suggest that humans share a mechanism for controlling the timing of blinks that searches for an implicit timing that is appropriate to minimize the chance of losing critical information while viewing a stream of visual events.” In simpler words, the researchers found that audiences watching movies with action sequences have a strong tendency to synchronize their blinking so that they don’t miss anything good.

    I’m not sure that this is interesting in and of itself, but it’s, um, eye-opening to think that we have our eyes closed for nearly 10% of our waking life. That’s roughly 10 full minutes of every movie lost to blinking. I imagine that editors already take this phenomenon into account, at least to some extent?

  • Dark Flash Photography

    Another paper from the upcoming SIGGRAPH 2009 conference: Dark Flash Photography. The researchers have developed a camera flash that uses a combination of infra-red and and ultra-violet light to illuminate a scene before capture, and an algorithm to denoise and color-correct the otherwise dimly-lit normal digital photo, producing a low-light image that is both noise-free and sharp (no need for long exposure, so no worry about camera shake or the subject moving). Seems like a killer idea, and immensely useful.

    The image above is the creepy-looking multi-spectral version – be sure to click through to their site to see the final photo compared with the noisy ambient light version.
