Good to see another timelapse! Next time you get a chance, it would neat to find out how close to the camera a subject stays generally in focus, and also what the field of view of the camera is (per recent “Foundation Camera Board information” thread on RPi forum).
Interesting timelapse, but quality for each frame suffers from compression artifacts. I have plans to use the camera in a telecine project already controlled by a PI. I need to get full size 2592×1944 frames in uncompressed raw RGB8 for ethernet transfer to a larger machine. Any chance you could provide a test picture – could be of your present out the window view, so I could judge the quality of the camera? yes, it is huge, I know – would be most appreciated though.
Can the camera capture a full sheet of paper? It would be very much appreciated if you could post a shot of it. I’m trying to make something that can scan a page. Also, how close can you get to a page before the text goes out of focus?
Oh I tried that a week ago and didn’t do anything with the shots. I _believe_ that the focus point is fixed in excess of 55cm. You can almost definitely take a pic of a whole page, it’ll just be a case of getting it in focus. I will do some experiments and see what I can do. Might have to wait until I get a battery pack for the Pi though as it’s all a bit delicate at the moment with things balanced on other things.
Thanks a lot for the picture, it showed quite a lot even if it is in jpg format (compressed about 7.5 times). First it looks quite good, so I think it will be OK for my use. The camera was not the one I thought, but maybe they opted for another version during the development. I got this info from your picture, in case you don’t have (obtained by InfanView):

Is the lens fixed? i.e. no focus adjustment possible please?
Also could you pls try if it is possible to get a raw RGB picture out of the camera. You don’t have to upload the picture, but the possibility for an uncompressed picture is essential for me.
It would probably be named .raw or .bmp by the system and be appr 15M in size.
Hope I don’t bother you too much…
Thanks a lot in advance.
The lens is definitely fixed – it’s basically the same sort you get in some Samsung mobile phones (at least I think it is).
I will try and get a RAW – will need to look at how to do it. I’m not even sure it’s possible yet.
Cool. Is the code available?
The code I used to generate the time lapse is:
mencoder “mf://*.jpg” -mf fps=30 -o test.avi -ovc lavc -lavcopts vcodec=msmpeg4v2:vbitrate=800
Is that what you meant?
I’m not sure:-) I’m not a coder, where do I put this and under what disto.
It’s a command-line call. So, you’d just type it in at the prompt.

I’m going to attempt to do some measured shots today… Will get a tape measure out 🙂

How about this? I’m not sure about uncompressed, but it’s the biggest pic the camera will take.
