  • Patent number: 10310624
    Abstract: An electronic apparatus includes a proximity sensor to detect an object, a device, and a control circuit to control the device. The control circuit executes a first mode which executes a first control for the device or the control circuit in response to an output of the proximity sensor corresponding to a first movement of the object and a second mode which skips the first control for an output of the proximity sensor corresponding to the first movement. The control circuit switches from the second mode to the first mode or from the first mode to the second mode based on an output of the proximity sensor corresponding to a second movement of the object different from the first movement. The second movement is a movement in which the object stays at a detection region for a first time, and then leaves the detection region within a second time.
