Abstract:
An imaging apparatus includes an imaging optical system, an imaging element acquiring an image of an object, a unit that acquires distance information corresponding to distance between the imaging optical system and the object, a unit that generates a map information corresponding to the image based on the distance information, a unit that is able to detect touch operation of a user on a display unit displaying the image and that detects a position in the image corresponding to a position touched by the user, and a control unit configured to acquire the distance information at the position of the acquired image from the map information to set the position as a focus point according to the acquired distance information, or configured to display, on the display unit, an enlarged image obtained by cutting an area of part of the image including the position.
