PORTABLE TERMINAL EQUIPMENT
Document Type and Number:
Japanese Patent JP3703185
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress consumption of power supply battery.
SOLUTION: When the terminal equipment is connected to a communication opposite party and a video conference is started, a CPU 10 receives image data to be sent from an image input device 20 and receives voice data to be sent from a voice input device 24 and uses a communication equipment 16 to send the image data and the voice data to the communication opposite party. A power supply management equipment 14 monitors a residual capacity of a battery 12 at all times and informs the battery residual capacity to the CPU 10 as required. When the residual capacity of the battery 12 reaches a prescribed capacity or below, the power supply management equipment 14 informs it to the CPU 10 that the residual capacity of the battery 12 is too small. The CPU 10 receiving the notice informs it to the communication opposite party via the communication equipment 16 that the transmission of the image data is stopped and only the voice data are sent at present. Then the CPU 1-0 gives a command to the power supply management equipment 14 to allow the equipment 14 to shut off supply of power to the image input device 20 and a camera 18.
