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 S608, the system control unit 218 determines to display the indicator in a display format for the front focus state (a second display format), and then executes step S611. The second display format is the display format illustrated in FIG. 10B.

In step S609, the system control unit 218 determines to display the indicator in a display format for the back focus state (a third display format), and then executes step S611. The third display format is the display format illustrated in FIG. 10C.

In step S611, the system control unit 218 determines the display position of the indicator and notifies the image processing unit 214 of the display position along with the display format. The image processing unit 214 generates an image of the indicator according to the display format in accordance with the notification and writes the image of the indicator to the address of the video memory region corresponding to the display position. As a result, the indicator is displayed superimposed on the live view image in the EVF 217 or the display unit 108.

The live view display operations will be described next with reference to the flowchart in FIG. 12. This processing is realized by the system control unit 218 loading a program recorded in the non-volatile memory 220 into the system memory 219 and executing the program. This processing can be executed during live view display, for example, in a shooting standby state, when shooting a moving image, or the like.
