Wireless circuit 201 performs transmission and reception of communication data. Cameras 204 and 205 take two moving images with different parallaxes and output two pieces of moving image data. Voice input/output section 202 acquires voice and outputs voice data. CPU 206 transmits multiple pieces of moving image data and voice data via wireless circuit 201, and, when the reception quality of communication data becomes equal to or below a reference value, stops at least one of cameras 204 and 205 to stop transmission of at least one of the multiple pieces of moving image data.
