Display control method and system

A display control method executed by a circuitry, the display control method comprising:

• detecting a first object and a second object from a first image captured by an electronic device, wherein the first object is different from the second object and the first object has a different planar orientation from the second object;
• generating positional relationship information between the first object and the second object, and distortional relationship information regarding a second shape of the second object in the first image with reference to a first shape of the first object in the first image;
• storing, into a memory, the positional relationship information and the distortional relationship information associated with a combination of the first object and the second object;
• detecting the first object and a third object from a second image captured by the electronic device, wherein the second object is not detected from the second image;
• generating other positional relationship information between the first object and the third object, and other distortional relationship information regarding a third shape of the third object in the second image with reference to a fourth shape of the first object in the second image;
• storing, into the memory, the other positional relationship information and the other distortional relationship information associated with a combination of the first object and the third object;
• acquiring a third image captured by the electronic device;
• specifying a position and a distortion of the third object in the third image when the third object is detected from the third image;
• and
• controlling a display to display a content associated with the second object based on the position, the distortion, the positional relationship information, the distortional relationship information, the other positional relationship information, and the other distortional relationship information when the first object and the second object are not detected from the third image, the content data being superimposed on the third image.

A non-transitory computer-readable storage medium storing a program which, when executed by a circuitry, causes the circuitry to:

• detect a first object and a second object from a first image captured by an electronic device, wherein the first object is different from the second object and the first object has a different planar orientation from the second object;
• generate positional relationship information between the first object and the second object, and distortional relationship information regarding a second shape of the second object in the first image with reference to a first shape of the first object in the first image;
• store, into a memory, the positional relationship information and the distortional relationship information associated with a combination of the first object and the second object;
• detect the first object and a third object from a second image captured by the electronic device, wherein the second object is not detected from the second image;
• generate other positional relationship information between the first object and the third object, and other distortional relationship information regarding a third shape of the third object in the second image with reference to a fourth shape of the first object in the second image;
• store, into the memory, the other positional relationship information and the other distortional relationship information associated with a combination of the first object and the third object;
• acquire a third image captured by the electronic device;
• specify a position and a distortion of the third object in the third image when the third object is detected from the third image;
• and
• control a display to display a content associated with the second object based on the position, the distortion, the positional relationship information, the distortional relationship information, the other positional relationship information, and the other distortional relationship information when the first object and the second object are not detected from the third image, the content data being superimposed on the third image.
