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(shuō)明書(shū)

FIG. 18 is a diagram illustrating an example of the live view display in the present embodiment. Focus guides 1801L and 1801R are displayed for a left image 1800L and a right image 1800R, respectively, in one frame of a live view image 1800 obtained by the image sensor constituting the image capturing unit 211. In the present embodiment, an indicator 1802 is further displayed between the left image 1800L and the right image 1800R, indicating the difference in the degree of focus between the left and right images, as well as the magnitude and direction of the defocus amount for each imaging optical system.

In addition to the effects of the third embodiment, the present embodiment presents the magnitude and direction of the defocus amount for each imaging optical system in a different format from the second embodiment, and thus the user can obtain the necessary information by referring to an indicator that is easy for them to understand.

In the present embodiment as well, the basic technical spirit is to provide some kind of display to assist shooting for the images formed by the individual imaging optical systems when a multi-scopic lens unit is mounted, and the display content is not limited to the degrees of focus, the difference therebetween, and so on. For example, a peaking pattern indicating overexposed or underexposed regions may be displayed superimposed on the live view image.

Fifth Embodiment

A fifth embodiment of the disclosure will be described next. The present embodiment relates to a technique for automatically adjusting the difference in the degree of focus between imaging optical systems when a multi-scopic lens unit is mounted.
