Abstract

An electronic device comprises: a motion detector configured to detect motion of the electronic device; a proximity detector configured to detect proximity of an object to the electronic device; a display unit; a memory; and at least one processor that function as: a control unit configured to control display preparatory processing for performing display on the display unit so as to start in response to predetermined motion of the electronic device being detected based on motion detected by the motion detector; and a display control unit configured to control display so as to be performed on the display unit in response to proximity of an object being detected by the proximity detector.

Claims

1. An electronic device comprising:

a motion detector configured to detect motion of the electronic device;

a proximity detector configured to detect proximity of an object to the electronic device;

a display unit;

a memory; and

at least one processor that function as;

a control unit configured to control display preparatory processing for performing display on the display unit so as to start in response to predetermined motion of the electronic device being detected based on motion detected by the motion detector; and

a display control unit configured to control display so as to be performed on the display unit in response to proximity of an object being detected by the proximity detector.

2. The electronic device according to claim 1,

wherein the display control unit controls display so as to be performed on the display unit after performing the display preparatory processing, in response to proximity of an object being detected by the proximity detector without detecting the predetermined motion.

3. The electronic device according to claim 1,

wherein the predetermined motion is motion bringing the electronic device close to a face.

4. The electronic device according to claim 1,

wherein the display unit is visible via an eyepiece unit of a viewfinder,

wherein the proximity detector functions as an eye-on detection unit configured to detect an eye being on the eyepiece unit, and

wherein the predetermined motion is motion involving a user moving the electronic device in order to have an eye be on the eyepiece unit.

5. The electronic device according to claim 4, further comprising a display monitor provided externally to the viewfinder,

wherein the predetermined motion is motion involving the user moving the electronic device in order to have an eye be on the eyepiece unit from a state of viewing the display monitor.

6. The electronic device according to claim 5,

wherein the display control unit continues display on the display monitor when the display preparatory processing is started, and stops display on the display monitor in response to display being performed on the display unit.

7. The electronic device according to claim 1,

wherein the predetermined motion is detected, in a case where motion in which acceleration in a vertical direction of the electronic device changes by greater than or equal to a threshold value and acceleration in a horizontal direction of the electronic device changes within a predetermined width is detected by the motion detector, within a predetermined period that includes a point in time at which positive and negative of acceleration in a front-back direction of the electronic device is reversed.

8. The electronic device according to claim 1,

wherein the display preparatory processing is processing for generating a driving voltage for driving the display unit.

9. The electronic device according to claim 8,

wherein, in the processing for generating the driving voltage, power supply is started gradually in order to suppress occurrence of an inrush current, after a power supply timing signal is input.

10. The electronic device according to claim 1,

wherein a condition for determining that the predetermined motion has occurred changes according to a type of interchangeable lens mounted to a lens mounting unit.

11. The electronic device according to claim 1,

wherein the electronic device is an image capturing apparatus having an image capturing unit.

12. A control method for an electronic device having a motion detection unit configured to detect motion of an electronic device, a proximity detection unit configured to detect proximity of an object to the electronic device and a display unit, the control method comprising:

controlling display preparatory processing for performing display on the display unit so as to start in response to predetermined motion of the electronic device being detected based on motion detected by the motion detection unit; and

controlling display so as to be performed on the display unit in response to proximity of an object being detected by the proximity detection unit.

13. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method of an electronic device having a motion detection unit configured to detect motion of an electronic device, a proximity detection unit configured to detect proximity of an object to the electronic device and a display unit, the control method comprising:

controlling display preparatory processing for performing display on the display unit so as to start in response to predetermined motion of the electronic device being detected based on motion detected by the motion detection unit; and

controlling display so as to be performed on the display unit in response to proximity of an object being detected by the proximity detection unit.
