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 - softwaer will support more flexible Exif data including GPS-related fields.--Andrey.filippov 10:40, 28 March 2008 (CDT)
