Foreword: -- This paper describes the recent imaging advances by Elphel, supplier of open source (hardware and software) cameras to customers that include Google (for select Street View and book scanning projects). It should interest imaging engineers, fans of open source, and those curious about open source hardware. The paper was written by Dr.
Elphel model 353 with internal HDD Elphel is an open hardware [ 1 ] and free software [ 2 ] camera designed by Elphel Inc. primarily for scientific applications, though due to its both open hardware and open source camera software, FLOSS , it can easily be customised for many different applications. Elphel Inc. was founded in 2001 by Russian physicist Andrey Filippov who emigrated to the United States of America in 1995. [ 3 ] The current model is named "Elphel 353". On the 6th December, 2010 [ 4 ] Elphel launched their first panoramic camera solution (that is publicly available) called "Elphel Eyesis". Eyesis can be seen as the successor (designed for low parallax [ 5 ] ) of the camera rig Elphel Inc. developed for Google Street View [ 6 ]

Andrey Filippov Elphel, Inc. Copyright © 2005 by the Author(s) Abstract FPGA are excellent devices for advancing the achievements of the Free Software into the hardware world and Elphel model 333 camera is a project in this area. Being the next step to the previous Elphel design that used reconfigurable Xilinx FPGA for the fast JPEG/motion JPEG compression the model 333 uses new Xilinx Spartan 3 to implement more advanced Ogg Theora videoencoder that is capable of processing 1.3Mpix images at 30 fps, larger images (up to 4.5 MPix) can be served at proportionally lower frame rate.
