INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Display is appropriately switched between an EVF display and a rear display of a camera based on proximity detection. A proximity detection unit detects proximity of a user viewing through the EVF. An orientation detection unit detects an orientation of the camera main body. If the proximity detection unit detects proximity within a predetermined threshold, a system control unit switches display to display of the EVF. If the orientation detection unit detects a predetermined motion, the system control unit changes a threshold of the proximity detection to a value indicating a distance far from the EVF. ## Claims ### Claim 1 An electronic apparatus comprising: a motion detector configured to detect a motion of the electronic apparatus; a proximity detector configured to detect proximity of an object; a display configured to be viewable when viewed through an eyepiece part; and a memory and at least one processor to perform the operations of the following unit: a control unit configured to, in a case where proximity detection information from the proximity detector corresponds to a distance closer than a threshold, perform control to start display on the display, and configured to, in a case where the motion detector detects a first motion, change the threshold to a value corresponding to a greater distance, wherein the control unit is configured to, in a case where the proximity detector does not detect proximity before a predetermined time elapses after the first motion is detected, perform control to change the threshold back to a value before change. ### Claim 2 (depends on 1) The electronic apparatus according to claim 1, wherein the first motion is a motion of a user moving the electronic apparatus to view through the eyepiece part. ### Claim 3 (depends on 2) The electronic apparatus according to claim 2, wherein the first motion is a motion including a predetermined amount or more of change in a vertical direction or a horizontal direction. ### Claim 4 (depends on 1) The electronic apparatus according to claim 1, wherein the control unit is configured to, in a case where the motion detector detects a second motion that is different from the first motion, stop a detection operation of the proximity detector or stop the control of the display on the display based on a detection result from the proximity detector. ### Claim 5 (depends on 4) The electronic apparatus according to claim 4, wherein the second motion is a motion of the electronic apparatus when a user is walking with the electronic apparatus. ### Claim 6 (depends on 4) The electronic apparatus according to claim 4, wherein the second motion is a periodic motion in a vertical direction or a horizontal direction. ### Claim 7 (depends on 4) The electronic apparatus according to claim 4, wherein the control unit is configured to, if the motion detector detects the second motion, reduce a threshold of a non-operation time before the electronic apparatus enters a power saving mode. ### Claim 8 (depends on 4) The electronic apparatus according to claim 4, wherein the control unit is configured to, if a user makes an operation after the detection operation of the proximity detector is stopped or after the control of the display on the display based on the detection result from the proximity detector is stopped, resume the detection operation of the proximity detector or resume the control of the display on the display based on the detection result from the proximity detector. ### Claim 9 (depends on 4) The electronic apparatus according to claim 4, wherein the control unit is configured to, if the motion detector detects the first motion after the detection operation of the proximity detector is stopped or after the control of the display on the display based on the detection result from the proximity detector is stopped, resume the detection operation of the proximity detector or resume the control of the display on the display based on the detection result from the proximity detector. ### Claim 10 (depends on 1) The electronic apparatus according to claim 1, wherein the control unit is configured to, in a case where the proximity detection information from the proximity detector indicates a distance farther than a predefined threshold while the display performs display, performs control to end the display, wherein the predefined threshold for ending the display is a threshold irrelevant to whether the motion detector detects the first motion. ### Claim 11 (depends on 1) The electronic apparatus according to claim 1, further comprising a second display that is different from the display, the second display being configured to be viewable without viewing through the eyepiece part, wherein the control unit is configured to switch display on the second display to the display on the display based on proximity detection by the proximity detector, and switch the display on the display to the display on the second display based on to non-detection of proximity by the proximity detector. ### Claim 12 (depends on 1) The electronic apparatus according to claim 1, wherein the electronic apparatus is an imaging apparatus including an imaging unit. ### Claim 13 A method for controlling an electronic apparatus including a motion detector that detects a motion, a proximity detector that detects proximity of an object, and a display that is viewable when viewed through an eyepiece part, the method comprising: performing control to start display on the display in a case where proximity detection information from the proximity detector corresponds to a distance closer than a threshold; and changing the threshold to a value corresponding to a greater distance in a case where the motion detector detects a first motion, wherein in a case where the proximity detector does not detect proximity before a predetermined time elapses after the first motion is detected, perform control to change the threshold back to a value before change. ### Claim 14 A non-transitory computer-readable storage medium storing computer executable instructions for causing a computer to execute a method for controlling an electronic apparatus including a motion detector that detects a motion, a proximity detector that detects proximity of an object, and a display that is viewable when viewed through an eyepiece part, the method comprising: performing control to start display on the display in a case where proximity detection information from the proximity detector corresponds to a distance closer than a threshold; and changing the threshold to a value corresponding to a greater distance in a case where the motion detector detects a first motion, wherein in a case where the proximity detector does not detect proximity before a predetermined time elapses after the first motion is detected, perform control to change the threshold back to a value before change.
