Pi Camera CCD

nbizzell
nbizzell over 10 years ago

I Was thinking about a project idea and wondered how long I could continuously (for video or long exposure) run the camera module without overhearing the CCD.

 

Does anyone know or done any experimenting with this?

    Hi Neil,

     

    The camera is CMOS (not CCD), according to this link http://www.raspberrypi.org/forums/viewtopic.php?t=47798&p=375566 the part is OV5647 from Omnivision, so the OV5647 datasheet will specify the temperature range the device can operate at, and hopefully the performance at different temperatures (I didn't check).

    Thank you. I had forgotten it was CMOS rather than CCD. Thank you also for the link.

     

    What I was looking for was the time it would be able to keep running for before reaching the maximum operating temperature. Probably going to be a rough estimate from experience rather than a hard and fast performance figure from the data sheet.

    I wasn't aware that he CMOS sensor generated enough heat that it could't be used continuously.

    Projects like this indicate that it could run on a continuous duty-cycle: Turn your Pi into a low-cost HD surveillance cam | Raspberry Pi

    fvan used one in the Catch Santa challenge, where it was running motion capture software.

     

    I've never heard of issues due to heat.

    I can confirm this, running it for hours without any problem.

    Thank you all for your responses.

     

    looks like my idea might work afterall. Not quite sure why I had it in my head the camera might overheat.
