Exif

In 353 camera in JPEG images we use standard EXIF fields (EXIF 2.2 specification from exif.org) for image description. All JPEG images have mentioned below fields (you can check this with any program what have support of Exif, in Linux with "exif" command line program, for example):

Tag name	Tag ID	Sample value	description
Image description	0x010E		coming soon...
Manufacturer	0x010F	Elphel, Inc	standard
Model	0x0110	353	standard
Software	0x0131	7.1.0.18	firmware version of camera at exposition moment
Date and Time	0x0132	1970:01:01 01:50:14	standard; time from FPGA RTC at sensor start moment
Artist	0x013B	00:0E:64:01:02:03	serial number of camera (Ethernet MAC address), ASCIIZ value
Exposure Time	0x829A	1/49 sec.	standard
Date and Time (original)	0x9003	1970:01:01 01:50:14	standard; time from FPGA RTC at sensor start moment
SubSecTimeOriginal	0x9291	686527	standard; time from FPGA RTC at sensor start moment

Note: in latest at this moment firmware (7.1.0.18) for 353 camera (CMOS sensor) all fields are correct, but with 363 camera (CCD sensor) we have wrong exposure time and shifted timestamp - TODO.

Exif data supported by Imgsrv and Camogm is described in Imgsrv#imgsrv_and_Exif_data. More changes are expected shortly - software will support more flexible Exif data including GPS-related fields.--Andrey.filippov 10:40, 28 March 2008 (CDT)
