IMAGE COMMUNICATION SYSTEM, IMAGE RECEPTION APPARATUS, IMAGE TRANSMISSION APPARATUS, IMAGE RECEPTION METHOD, IMAGE TRANSMISSION METHOD, AND PROGRAM

摘要

An image communication system includes an image transmission apparatus and an image reception apparatus. The image transmission apparatus includes a transmission-side wireless communication unit that transmits image data by radio waves. The image reception apparatus includes a reception-side wireless communication unit that receives, by radio waves, the image data transmitted by the transmission-side wireless communication unit. At least one of the image transmission apparatus and the image reception apparatus includes a radar detection unit that executes a radar radio-wave detection process in a communication channel that can be used by the transmission-side wireless communication unit and the reception-side wireless communication unit to communicate the image data. At least one of the image transmission apparatus and the image reception apparatus includes a channel use confirmation unit that executes channel use confirmation to confirm whether or not the communication channel is usable, by continuously executing, for a predetermined time, the detection process performed by the radar detection unit.
