My Raspberry Pi - based microscope camera uses the high-quality Raspi camera that was released in early 2020. It features a 12.3 megapixel Sony IMX477 sensor, with a pixel size of 1.55μm × 1.55μm, which is twice the pixel area than the previous Raspberry Pi camera model. The image quality is much better than the previous Raspi camera models, or the old AmScope 3 MP USP camera (MU300) I had been using before.
Timelapse video of a house demolition with a time-stamp overlay
Sadly, our neighbors sold their house and it was recently demolished to make way for two new buildings. On the plus side, this gave me an opportunity to try out my Raspberry Pi camera and make a time lapse movie of the process. Specifically, I wanted to try a quick-and-easy way to add a time-stamp in the corner of the video to give an indication of the current time of the day.
A video filmed at 300 fps of an axolotl trying to snatch up a food pellet. (Unfortunately, it fails both times to swallow the pellet.) Playback is slowed down to about 10x, and then 50x the actual speed of the feeding reflex. Filmed with a Casio Exilim EX-F1. Video quality is certainly not the best, but the video is still interesting, I think.
The sequence below was shot in the butterfly house of the Pacific Science Center in Seattle in 2010.
Filmed at 500 fps. This video consists of about 730 frames, which means the whole sequence took less than 1-½ seconds in real time. Shot with a Phantom Miro 4 color high-speed camera, which was graciously loaned to the Daniel Lab by its manufacturer, Vision Research.
