According to the present invention, a main control section (2) monitors a reception field strength and an error ratio of received data, and when it is determined from the monitoring result that a communication environment is deteriorated, an image processing section (10) performs a process of thinning the number of frames of image data picked up by a camera (11) in response to an instruction from the main control section (2), thereby reducing the amount of image data to be transmitted to a communication destination per unit time via a radio section (1). |
