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.
Claims14
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:
- an obtaining unit configured to obtain a first live view image captured through a first optical system and 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;
- and
- a display control unit configured to display a first display item indicating a difference between focus conditions of the first live view image and the second live view image together with the first live view image and the second live view image.
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:
- an obtaining unit configured to obtain a first live view image captured through a first optical system and a second live view image captured through a second optical system, wherein the first and second live view images have parallax with each other, wherein optical axes of the first and second optical systems are parallel, and wherein a difference in degree of focus between the first optical system and the second optical system is adjustable according to user operation;
- and
- a display control unit configured to display the first live view image 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.
