Claim:
1. An electronic device, comprising: an imaging device that captures an image of an object and generates image data of the object; a tilt angle detector that detects a tilt angle of the imaging device with respect to a horizontal plane; an azimuth detector that detects an azimuth angle between a reference orientation based on a preset orientation and an optical axis of the imaging device; a display controller that causes a display to display target information indicating a direction to a target position for instructing a position of a capturing area of the imaging device in an image corresponding to the image data, with the optical axis of the imaging device being a reference, based on the tilt angle detected by the tilt angle detector and the azimuth angle detected by the azimuth detector; a memory that records focal distance information on a focal distance of the imaging device; an angle-of-view calculating processor that calculates an angle-of-view of the imaging device, based on the focal distance information recorded by the memory; and a coordinate calculating processor that calculates a coordinate of the target position and coordinates of a boundary of the angle-of-view calculated by the angle-of-view calculating processor, based on the tilt angle detected by the tilt angle detector and the azimuth angle detected by the azimuth detector, wherein the display controller causes the display to display the target information, when the coordinate of the target position calculated by the coordinate calculating processor is not within the angle-of-view.
