Methods for determining operational settings and related devices

A method for determining output signal format of a function for use in a device, comprising:

• providing a table comprising a plurality of first fields for recording country information and a plurality of second fields, each of which being corresponding to one first field, for recording output signal formats;
• retrieving/acquiring country information on the device;
• and
• determining an output signal format of a function on the device based on the country information by looking up the table.

A method for determining exposure time range of an image capturing function for use in a device, comprising:

• providing a table comprising a plurality of first fields for recording country information and a plurality of second fields, each of which being corresponding to one first field, for recording exposure time ranges;
• retrieving/acquiring country information on the device;
• and
• determining an exposure time range of the image capturing function on the device based on the country information by looking up the table.

A method for adjusting system time for use in a device, comprising:

• providing a table comprising a plurality of first fields for recording area information and a plurality of second fields, each of which being corresponding to one first field, for recording time zone information;
• retrieving/acquiring a first area information currently located by the device;
• providing a second area information previously located by the device;
• obtaining a first time zone information for the first area information and a second time zone information for the second area information by looking up the table;
• calculating a time difference based on the first and second time zone information;
• and
• adjusting the system time of the device based on the time difference.
