I found a really great site, which helped me understand some icons that I never understood what they are for or what information they give, so I would like to share it. The dictionary (which is in English) also provides the definition of acronyms, initials and other words related to digital cameras and the photographic world.
There are some that particularly caught my attention:
Indicates that the camera uses APS roll (Advanced PhotoSystem)
Bar code program mode, indicates that the camera is in barcode reader mode.
High speed continuous shooting.
No it doesn't mean you can play Pac Man. Notifies the level of opening (open-closed) of certain camera devices.
