1. An image capturing apparatus comprising: an imager that captures an image; a focus controller that controls a focus of the imager; and an object selection receiver that receives a selection of objects by an operator, wherein: the imager captures a plurality of images that have differing focal positions while shifting a focal position of the imager, the focus controller controls the imager to shift the focal position of the imager and to cause the imager to capture the plurality of images by successively capturing the plurality of images while the focal position is shifting from a closer side to a farther side, the object selection receiver further receives priority for any object to be selected, and the focus controller controls, based on the priority, the focal position of the imager so that the objects are captured in focus in any of the plurality of images and at least one of the plurality of images is captured at a focal position at which an object whose priority received is higher than other objects has a higher focusing degree than other objects.
