The camera notification reception in step S423 is performed. Details of the processing will be described later with reference to FIG.

  When the camera notification reception process in step S423 is completed, the process proceeds to step S441 in FIG.

  In step S441, the communication system control circuit 350 determines whether there is an incoming call from another communication device or communication base station via the antenna 328 and the communication unit 326. If there is no incoming call from another communication apparatus or communication base station (NO in step S441), the process proceeds to step S442, and if there is an incoming call from another communication apparatus or communication base station (YES in step S441), step The process proceeds to S447.
