Abstract

An apparatus comprising a sensor capable of generating a signal pair used in focus detection. The apparatus obtains, based on a defocus amount obtained using the signal pair, a focus distance of a lens unit that is mounted to the apparatus and adjusts a focus distance of the lens unit based on the obtained focus distance. When the lens unit is a multi-scopic lens unit having a plurality of optical systems having different axes, the apparatus obtains the focus distance using an adjustment value obtained based on an axis position that is a position on the sensor through which an axis of the multi-scopic lens unit passes.

Claims (84)

1. An electronic device that controls a display device to perform a live view display based on a captured image, comprising:

at least one processor; and

a memory coupled to the at least one processor, the memory having instructions that, when executed by the processor, performs operations as:

5. An electronic device that controls a display device to perform a live view display based on a captured image, comprising:

at least one processor; and

a memory coupled to the at least one processor, the memory having instructions that, when executed by the processor, performs operations as:

a display control unit configured to perform:

a third display control in which a third display item indicating a different between focus conditions of the first live view image and the second live view image is displayed together with the first live view image and the second live view image.

6. An electronic device that controls a display device to perform a live view display based on a captured image, comprising:

at least one processor; and

a memory coupled to the at least one processor, the memory having instructions that, when executed by the processor, performs operations as:

a display control unit configured to perform:

wherein in a case where focus conditions of the first optical system and the second optical system are adjusted in tandem, the display control unit updates display of the first display item and the second display item in tandem.

7. A method performed by an electronic device for controlling a display device to perform a live view display based on a captured image, comprising:

obtaining a first live view image captured through a first optical system;

obtaining a second live view image captured through a second optical system,

wherein the first and second live view images have parallax with each other and

wherein optical axes of the first and second optical systems are parallel;

performing a first display control in which the first live view image is to be displayed with a first display item superimposed on the first live view image and indicating information on a focus condition of the first live view image; and

performing a second display control in which the second live view image is to be displayed with a second display item superimposed on the second live view image and indicating information on a focus condition of the second live view image, and

selectively performing either the first display control or the second display control.

8. The method according to claim 7 , wherein the first display item is superimposed at a position based on a position of the optical axis of the first optical system, and the second display item is superimposed at a position based on a position of the optical axis of the second optical system.

9. The method according to claim 7 , wherein the first display item is superimposed at a position around a focus detection region of the first live view image and the second display item is superimposed at a position around a focus detection region of the second live view image.

10. A method performed by an electronic device for controlling a display device to perform a live view display based on a captured image, comprising:

obtaining a first live view image captured through a first optical system;

obtaining a second live view image captured through a second optical system,

wherein the first and second live view images have parallax with each other and

wherein optical axes of the first and second optical systems are parallel;

performing a third display control in which a third display item indicating a different between focus conditions of the first live view image and the second live view image is displayed together with the first live view image and the second live view image.

11. A method performed by an electronic device for controlling a display device to perform a live view display based on a captured image, comprising:
