Method and device for outputting an image

An electronic device for performing an image output method, the electronic device comprising:

• a memory in which a program for outputting an image is recorded;
• and
• a processor configured to perform the program wherein the program is configured to perform:
• loading a plurality of basic image tiles with a first resolution being preset for a graphic space set based on a virtual coordinate system;
• setting a coordinate of a virtual camera on the virtual coordinate system;
• determining at least one target basic-image tile among the plurality of basic image tiles based on the coordinate of the virtual camera;
• transmitting information on the target basic-image tile to a server;
• receiving a plurality of detailed image tiles with a second resolution corresponding to the target basic-image tile from the server;
• and
• outputting an image with the second resolution based on the plurality of detailed image tiles when the virtual camera zooms in on the target basic-image tile.

An image output method performed by a system for outputting an image to a user, the image output method comprising:

• loading, by a user's terminal of the system, a plurality of basic image tiles with a first resolution, the plurality of basic image tiles being preset for a graphic space set based on a virtual coordinate system;
• setting, by the user's terminal, a coordinate of a virtual camera on the virtual coordinate system;
• determining, by the user's terminal, at least one target basic-image tile among the plurality of basic image tiles based on the coordinate of the virtual camera;
• transmitting, by the user's terminal, information on the target basic-image tile to a server of the system;
• receiving, by the user's terminal, a plurality of detailed image tiles with a second resolution corresponding to the target basic-image tile from the server;
• and
• outputting an image with the second resolution based on the plurality of detailed image tiles when the virtual camera zooms in on the target basic-image tile.
