in a case where gazing at a position at which the specific object is detected by the detection unit is being performed, the control unit shortens a period of the gazing in the conditions for changing the selected position as compared with a case where gazing at a position at which the specific object is not detected by the detection unit is being performed.
3. The electronic device according to claim 2 , wherein the specific object is a face.
4. The electronic device according to claim 1 , wherein, in a case where a position of the gazing moves between different portions of a face displayed on the display, the control unit shortens a period of the gazing in the conditions for changing the selected position as compared with a case where the position of the gazing moves within a single portion of the face.
5. The electronic device according to claim 1 , wherein, in a case where a position of the gazing moves between different faces displayed on the display, the control unit shortens a period of the gazing in the conditions for changing the selected position as compared with a case where the position of the gazing moves within a single face displayed on the display.
6. The electronic device according to claim 1 , wherein the control unit is further configured to change a period of the gazing in the conditions for changing the selected position based on an angle of view of an image displayed on the display.
7. The electronic device according to claim 1 , wherein the control unit is further configured to shorten a period of the gazing in the conditions for changing the selected position as a distance between the selected position and the position of the gazing increases.
8. The electronic device according to claim 1 , further comprising an operation member configured to receive an operation by the user, wherein
the control unit is further configured to change the selected position in accordance with an operation on the operation member.
9. The electronic device according to claim 1 , wherein the viewed point conditions corresponding to the fact that the gazing has been performed include a condition of a movement amount of the input position being less than a predetermined threshold.
10. A non-transitory computer readable medium that stores a program for causing a computer to function as the units of the electronic device according to claim 1 .
11. A method of controlling an electronic device, the method comprising:
a receiving step of receiving a line of sight input by a line of sight of a user looking at a display; and
a controlling step of performing control such that a selected position in the display is changed in accordance with an input position resulting from the line of sight input, wherein
the control is performed A) such that the selected position is changed based on gazing at a first position in response to satisfaction of a viewed point condition corresponding to a fact that gazing at the first position at a first distance from the selected position has been performed for a first period, and
B) such that the selected position is changed based on gazing at a second position in response to satisfaction of a viewed point condition corresponding to a fact that gazing at the second position at a second distance which is farther from the selected position than the first distance has been performed for a second period shorter than the first period.
12. An electronic device comprising:
at least one memory and at least one processor which function as:
a receiving unit configured to receive a line of sight input by a line of sight of a user looking at a display on which an image is displayed;
a detection unit configured to detect a specific object from the image; and
a control unit configured to perform control such that a selected position in the display is changed in accordance with an input position resulting from the line of sight input, wherein
the control unit performs control
A) such that the selected position is changed based on gazing at a third position in response to satisfaction of a viewed point condition corresponding to a fact that gazing at the third position at which the specific object is not detected by the detection unit has been performed for a third period, and
B) such that the selected position is changed based on gazing at a fourth position in response to satisfaction of a viewed point condition corresponding to a fact that gazing at the fourth position at which the specific object is detected by the detection unit has been performed for a fourth period shorter than the third period.
13. The electronic device according to claim 12 , wherein the specific object is a face.
14. The electronic device according to claim 12 , wherein, in a case where a position of the gazing moves between different portions of a face displayed on the display, the control unit shortens a period of the gazing in the conditions for changing the selected position as compared with a case where the position of the gazing moves within a single portion of the face.
15. The electronic device according to claim 12 , wherein, in a case where a position of the gazing moves between different faces displayed on the display, the control unit shortens a period of the gazing in the conditions for changing the selected position as compared with a case where the position of the gazing moves within a single face displayed on the display.
16. The electronic device according to claim 12 , wherein the control unit is further configured to change a period of the gazing in the conditions for changing the selected position based on an angle of view of an image displayed on the display.
17. The electronic device according to claim 12 , wherein the control unit is further configured to shorten a period of the gazing in the conditions for changing the selected position as a distance between the selected position and the position of the gazing increases.
18. A non-transitory computer readable medium that stores a program for causing a computer to function as the units of the electronic device according to claim 12 .
19. A method of controlling an electronic device, the method comprising:
a receiving step of receiving a line of sight input by a line of sight of a user looking at a display on which an image is displayed;
a detecting step of detecting a specific object from the image; and
a controlling step of performing control such that a selected position in the display is changed in accordance with an input position resulting from the line of sight input, wherein
the control is performed A) such that the selected position is changed based on gazing at a third position in response to satisfaction of a viewed point condition corresponding to a fact that gazing at the third position at which the specific object is not detected in the detecting step has been performed for a third period, and
B) such that the selected position is changed based on gazing at a fourth position in response to satisfaction of a viewed point condition corresponding to a fact that gazing at the fourth position at which the specific object is detected in the detecting step has been performed for a fourth period shorter than the third period.
