PROBLEM TO BE SOLVED: To allow a system even with a slow rising time to receive an incoming call in response to the call by storing data just before transition to a low power mode and discriminating the arrival of incoming calls on the basis of the state of the system. SOLUTION: The system is provided with a system controller 101 that acquires fault information of a recording section recording at least an image and executes control on the basis of the information in the case that the system is restored from the low power mode to a usual state and with an FCU 115 that has a DRAM 308 storing received data, a FLASH-ROM 304, and a backed-up SRAM 307 storing system information. The FCU 115 stores the system information with respect to a state of itself just before the low power mode to the backed-up SRAM 307 and discriminates the arrival of incoming calls on the basis of the system information stored in the backed-up SRAM 307. |
