Finally, I got a working pixel lapse software under Linux 🙂 It’s a bit late (and I have to work tomorrow), code is rather dirty but I’ll publish it as soon as possible (btw that’s why I needed a webcam and a library to read it yesterday). Originally,
"pixel lapse" photography is the process of creating an image one pixel at a time. Beginning in the upper left corner, pixels are captured sequentially at a set rate until the entire image is formed.
Unfortunately, their software only runs on MacOS and Windows and requires Quicktime. Here, I "only" use OpenCV which is free and available under all the OS mentioned in this post. More details soon …
The “full-size” (640×480) image is here on Flickr
Edit on November 5th, 2008: version 0.1 of the software is available here.
A small post just to keep this command at hand:
mplayer -fps 30 -tv driver=v4l:width=640:height=480:device=/dev/video1 tv://
This allows you to watch what your webcam “sees” (provided it uses a video4linux webcam). Btw, Cheese is funny to use too!
I was also trying to find a decent Python library for video4linux but I only found outdated ones (libfg, 2003, and pyv4l, 2002). I guess I’ll have to use some C library for a small project I’ll tell you about later 😉
