[0073] Step S170: The communication control unit 372 detects that the image captured by the image capturing unit 23 has been captured for a predetermined period of time or more. The communication control unit 372 determines whether or not an object has been photographed. Performing an image analysis of the image, in which images of objects contained in the image are analyzed, e.g. For example, the identification is based on template matching or machine learning. The communication control unit 372 receives the result of the image analysis from the image analysis unit 32. Based on the result of the image analysis by the image capture unit 32, an object is detected in the image captured by the image capture unit 23 for a predetermined period of time or more. It is determined whether the body is not imaged.

[0074] The communication control unit 372 detects whether an object has been captured in an image captured by the image capturing unit 23 for a predetermined period of time or longer. If it is determined that the user is not present (step S170; YES), the process of step S180 is executed. On the other hand, the communication control unit 372 detects whether an object is present in the image captured by the image capturing unit 23 within a predetermined time. If it is determined that the image has been captured (step S170; NO), the process of step S1100 is performed. Execute.
