Electronic device, control method, and recording medium

A method for controlling an electronic device comprising a camera, a location sensor, a display, a communication interface, and a controller, the method comprising:

• causing, using the controller, the communication interface to acquire a database from an external source, the database including name information of tangible objects, first location information indicating locations of the tangible objects, and first feature point information related to feature points of the tangible objects;
• generating, using the controller, image recognition information on the basis of a captured image captured by the camera, the image recognition information including distance information indicating a distance from the electronic device to a particular subject and second feature point information related to feature points of the particular subject;
• identifying, using the controller, a name of the particular subject on the basis of the image recognition information, the database, and second location information indicating a location of the electronic device acquired by the location sensor;
• and
• causing, using the controller, an overlay image yielded by overlaying the name on the captured image to be displayed on the display.

A non-transitory computer-readable recording medium including computer program instructions to be executed by an electronic device comprising a camera, a location sensor, a display, a communication interface, and a controller, the instructions causing the controller to:

• cause the communication interface to acquire a database from an external source, the database including name information of tangible objects, first location information indicating locations of the tangible objects, and first feature point information related to feature points of the tangible objects;
• generate image recognition information on the basis of a captured image captured by the camera, the image recognition information including distance information indicating a distance from the electronic device to a particular subject and second feature point information related to feature points of the particular subject;
• identify a name of the particular subject on the basis of the image recognition information, the database, and second location information indicating a location of the electronic device acquired by the location sensor;
• and
• cause an overlay image, yielded by overlaying the name on the captured image, to be displayed on the display.
