   I want to read a digital display of readings and send it to a computer. Can I do this using Maple?

   YES !!! Not only with Maple, also with any MCU from 8 to 32 bits.

   What sort of camera? You will almost certainly not be able to do anything at a reasonable frame rate, but to capture images and display them or scuttle them over to a computer - this has been done before on these very forums!

   Quoted from sparkfun, "The LinkSprite JPEG color camera allows you to capture and output JPEG images through UART". http://www.sparkfun.com/products/10061
   This may do the trick for you.

   Why you think about camera? In original post no word camera - only from digital display.

   Because the thread is called camera interface?

   There may be another way worth considering.

   Is the camera a Canon which supports the "Canon Hack Development Kit" http://chdk.wikia.com/wiki/CHDK ?

   If it is, you have a wide range of options (I have two digital cameras which support CHDK, it is a brilliant piece of software)

   CHDK supports a pile of extra functionality, including executing Lua scripts, and controlling the cameras USB port and display.
   I haven't tried to program it, but there are range of possibilities.
   So if you want simple information, CHDK could be used to write it in an easy to capture form (like a bar code), or it might be able to signal over the USB. It may well allow you to send the data you need directly to the host PC. Sorry I can't be more helpful.
