Abstract
An image pickup element performs photoelectric conversion on an optical image formed by an interchangeable lens. A ranging unit measures a distance to each object from signals for detecting a phase difference from the image pickup element. A body microcomputer calculates a de-focusing amount of each object, generates a focus guide for each object with a size or a (detailed or simple) content according to the de-focusing amount, and displays the focus guide on a display unit in a superimposed manner on an image captured by the image pickup element. A user adjusts the focus of the interchangeable lens using a focus ring by referring to the screen of the display unit.
