Raspberry Pi Camera stills output VS video output - comparison

After reading a few comments in the Pi forums about perceived quality differences between stills and video, I thought I’d test it out for myself. Some people are saying that the video quality is better than stills. “Quality” is quite a subjective thing, but resolution is a bit easier to test. This was a pretty simple test. I left the camera propped up facing the same Nissan Micra as yesterday’s blog and remotely took a still shot (by ssh) raspistill -t 3000 -vf -o reg-plate.jpg …and then I shot a few seconds of 1080p@30fps video… […more…]

Comparison of real resolving power of RasPiCam with other cameras

Talk to any photography geek and you’ll hear that the glass is a lot more important than the number of pixels. This is definitely true. It doesn’t matter how many pixels you’ve got if the light isn’t gathered and focussed nicely onto the sensor. Sensor size is the other large factor. The larger the sensor, the better the pictures (generally). The optimum is therefore good glass and a big sensor. With phone cameras, you usually have a small sensor and a small lens, which is far from ideal. Good glass costs hundreds or thousands and […more…]

How to stream video from your RasPiCam to your Nexus 7 tablet using VLC

Yesterday I went to the Cambridge Jam. It was a very good Jam. I met four members of the Raspberry Pi Foundation and they were all extremely nice people. I took three demos with me: Gertboard “Whackadoodle” Wii controller Wii controller nunchuk Guzunty car RasPiCamCorder I had the RasPiCamcorder streaming live video to my PC via my phone as WiFi router. It worked quite well, but with poor latency. It took several seconds for changes to appear on the screen. I hadn’t had time to monkey about with the commands and was streaming 1080p at […more…]

How to make a standalone camcorder from your Raspberry Pi and RasPiCam

On day 2 of Raspberry Pi Camera ownership I decided it was time to make the new RasPiCam into a camcorder that could be taken anywhere and used to shoot video. Hold on, there’s issues with that aren’t there? Sure there are, but there’s ways round ’em too ;) So here’s how I did it. I’ll be taking this to the Cambridge Jam tomorrow. :) Ingredients 1 Switching regulator 1 Bluetooth serial adaptor 1 Raspberry Pi with latest updated Raspbian 1 Raspberry Pi Camera Connectors for battery, reg and Bluetooth adaptor 1 power source (I’m […more…]

How to shoot video and convert it to something you can edit in Pinnacle and other programs

Yesterday I got my shiny new “RasPiCam” Raspberry Pi camera module about half an hour before I had to go out and teach. Being a good boy scout (although I never was one) I was ready for it and had it up and running within five minutes of it coming through the letterbox. But when I got back from school, I shot some test videos that I wanted to edit and publish. You know how it is. You have to publish something on day 1 or it didn’t happen, right? :) I knew there must […more…]
