COMMUNICATION DEVICE WIRELESSLY COMMUNICATING WITH EXTERNAL DEVICE, CONTROL METHOD FOR COMMUNICATION DEVICE, AND STORAGE MEDIUM
First Claim
1. A communication device comprising:
- an image capturing unit configured to capture an object to acquire an image of the object;
a detection unit configured to continuously determine presence of an external device based on the image acquired by the image capturing unit;
a first wireless communication unit configured to perform wireless communication according to a first communication standard; and
a control unit configured to perform control so that processing for establishing wireless communication with the external device via the first wireless communication unit is started if the external device is detected by the detection unit,wherein, if the external device is not detected by the detection unit for a certain time period or certain number of times after the wireless communication with the external device is established by the first wireless communication unit, the control unit performs control so that the wireless communication with the external device by the first wireless communication unit is disconnected, andwherein, if the external device is again detected by the detection unit before the certain time period elapses, the control unit performs control so that the wireless communication with the external device by the first wireless communication unit remains connected.
