摘要

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.

說明書

In step S706, the system control unit 218 determines whether an operation for ending the live view display has been detected. If the system control unit 218 determines that the ending operation has been detected, the live view display is ended, whereas if the system control unit 218 does not determine that the ending operation has been detected, the processing is repeated from step S702, and the live view display is continued. Although the processing is described here as being repeated from step S702, after the processing of step S702 is performed once, steps S703 and S706, or steps S704 to S706, may be repeated, according to the determination result from step S702, until the lens unit is removed.

As described thus far, in the present embodiment, a focus guide for each live view image formed by the imaging optical system is displayed according to the number of optical axes of the mounted lens unit. Therefore, when the binocular lens unit 300 having two optical axes (imaging optical systems) is mounted, focus guides are displayed for both the left image and the right image of the live view image.
