Abstract
In a cellular video telephone having a built-in battery, the remaining electric power of the battery is detected. The data communication speed and the display of image on a display are variably controlled based on the detected remaining battery power, that is, the communication speed is lowered and the display is turned off, as the remaining power decreases. Alternatively or in addition, the communication speed and the image display are controlled variably based on availability of external power source in the course of voice and image communication.
