Stop Motion

Stop Motion Animation on the OLPC would be a great feature for the built in camera and Record activity. Remote shutter control would be a nice feature however, otherwise you will introduce camera-shake into your footage.

Isforinsects has volunteered to do a how-to as a content package. Thinking: Photos and/or video, all no vocals or words. That way nothing to translate.

One might use MJPEG Tools to assemble Record photos into an ogg, which should work with gstreamer and helix.

Paper Animation

Paper animation can be done as conventional drawn frame animation, shadow-puppets or cutout figures (think South Park). There is likely information about this on wikihow that could be gleaned.

Lighting

The OLPC screens with full lcd brightness might provide a decent RGB controlled fill light. Will experiment.

Display reports someone's 64 cd/m^2 measurement. x 0.0155 is... 1 cd. Perhaps 1 lm. But they tested an old prototype, so a B4/XO-1 may be different. MitchellNCharity 00:44, 12 October 2007 (EDT)
I just want to say that this is a great idea. I suspect that the screen would only have an effect in relatively low-light conditions, but it would be great if the camera still works in these conditions. —Joe 10:24, 12 October 2007 (EDT)
Dang. We need light. The longer the exposure time, the more noise-grain in the image. Since we're dealing with a relatively low quality sensor in the first place, we're already going to be fighting grain. Specialization is for Insects 11:38, 12 October 2007 (EDT)
Really? I would have thought that you'd get less noise with longer exposure times — more photons = relatively more signal = relatively less noise. So instead of taking a single-frame picture, you take a short video and then use the median value of each pixel over time. Sure, it wouldn't be practical for typical photography, but it should work great for a static scene, as in stop-motion photography. Or am I missing something? —Joe 14:01, 12 October 2007 (EDT)

To Do

  1. Glean wikihow for conventional animation and drawing how-tos
  2. Research brightness of XO-B4's
  3. Get hands on with XO for shutter testing
