A method and an apparatus to provide a service using a sensor and image recognition in a portable terminal that supports Augmented Reality (AR). The method includes determining whether the portable terminal is parallel to ground using an acceleration sensor. When the portable terminal is parallel to the ground, either a map including nearby Point Of Interest (POI) information or constellation information is displayed.

An imaging apparatus includes an electronic viewfinder unit that includes an image display element configured to display an image, an eyepiece optical system configured to enable the image to be observed from a rear side of the imaging apparatus, and a holder unit configured to hold the eyepiece optical system and the image display element. The holder unit moves the eyepiece optical system from a retracted position in which the eyepiece optical system is retracted in a body of the electronic viewfinder unit to an observable position in which the eyepiece optical system projects from the body of the electronic viewfinder unit to the rear side from the retracted position, and moves the image display element to the rear side.

The present disclosure includes an imaging control apparatus, an imaging control method, and an imaging apparatus. The imaging control apparatus includes a focal point detection control circuitry configured to receive first information from a range-finding area of a dedicated phase difference detection sensor and second information from a range-finding area of an image plane phase difference detection sensor, and detect a focal point based on at least one of the first information or the second information.

There is provided a camera of which operability is good regardless of the brightness of the surrounding environment. The brightness of the surrounding environment is detected by a brightness detection unit provided in a camera. The contents of settings of the camera are displayed on a sub-display 18 in a situation in which the surrounding environment is bright. The contents of settings of the camera and an image representing the set state of a shutter speed dial 33 are displayed on the sub-display 18 in a case in which the surrounding environment is dark.
