Classification: CPC H | IPC H

Claim 0:
1. An apparatus comprising:
a sensor capable of generating a signal pair used in focus detection;
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, based on a defocus amount obtained using the signal pair, a focus distance of a lens unit that is mounted to the apparatus; and
an adjusting unit configured to adjust a focus distance of the lens unit based on the obtained focus distance,
wherein when the lens unit is a multi-scopic lens unit having a plurality of optical systems having different optical axes, the obtaining unit 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.
