Battery operated radio transmission terminal, e.g. cellular video telephone in which transmission speed is changed based on remaining battery energy

摘要

The terminal includes an energy detector (11) for determining the remaining energy in a built-in battery. A speed setting device sets different data transmission speeds based on the detected remaining energy. The data transmission speed may be increased when it is detected that energy is being supplied from an external source. The terminal may include an image transmission device, the resolution or brightness being increased when an external energy source is detected. An Independent claim is included for a radio transmission terminal.
