An image receiving terminal includes a communicator and one or more processors. An elapsed time is a time period from a time point at which a vertical synchronization signal is generated to a time point at which a specific packet is received by the communicator. The processor sets a determination reference time on the basis of the plurality of measured elapsed times. The processor determines whether the communication channel which is used by the communicator is to be switched to another communication channel on the basis of the set determination reference time and the elapsed time measured after the determination reference time has been set. The processor controls switching of the communication channel which is used by the communicator on the basis of the result of determination of the communication channel.
