The raw sensor data can be obtained on the NC353L camera by reading from the /dev/ccam_img file.
Here you can find a PHP script example on how to acquire a RAW image from Elphel camera.: http://elphel.cvs.sourceforge.net/viewvc/elphel/elphel353-8.0/packages/web/353/php_top/raw.php?view=markup
That script accepts parameters similar to parsedit.php, i.e. BITS=16 to get 16 raw image in 2 bytes/pxel format. In the case of MT9P031 sensor output data is left-shifted by 3 to get into the 0..2^15 range.
Attention: If the image acquisition is not stopped, you may get part of the image from one frame, and the other part - from the next one. In default configuration data from the sensor is continuously acquired to the memory attached to the FPGA--Andrey.filippov 01:26, 13 June 2008 (CDT)
Adding parameter "stop" to the URL would stop sensor acquisition so the video buffer will not be overrun during data readout.It is also possible to trigger camera externally (or from the internal FPGA timer).--Andrey.filippov 09:45, 11 October 2012 (PDT)
