User interface control device, user interface control method, computer program and integrated circuit

A control method, comprising:

• acquiring a stereoscopic image of a subject, the stereoscopic image including a first viewpoint image and a second viewpoint image;
• specifying a placement position of a graphic part on the first viewpoint image;
• calculating a rendering area of the graphic part on the placement position of the first viewpoint image;
• acquiring a position of a first viewpoint subject displayed on the first viewpoint image, wherein the first viewpoint subject coincides with the rendering area of the graphic part;
• calculating first depth information of the graphic part in the stereoscopic image according to a relative position of the graphic part to the position of the first viewpoint subject;
• acquiring second and third depth information of the first viewpoint subject, the second depth information indicating a smaller depth than the first depth information and the third depth information indicating a greater depth than the first depth information;
• presenting a first alternative, a second alternative, and a third alternative for setting a depth of the graphic part in the stereoscopic image, the first alternative representing the first depth information, the second alternative representing the second depth information, and the third alternative representing the third depth information;
• and
• pasting the graphic part in the stereoscopic image according to a selection of one of the first alternative, the second alternative, or the third alternative, the graphic part not being originally included in the stereoscopic image in the acquiring.

A computer-readable non-transitory recording medium storing a computer program, the computer program causing a computer to execute:

• acquiring a stereoscopic image of a subject, the stereoscopic image including a first viewpoint image and a second viewpoint image;
• specifying a placement position of a graphic part on the first viewpoint image;
• calculating a rendering area of the graphic part on the placement position of the first viewpoint image;
• acquiring a position of a first viewpoint subject displayed on the first viewpoint image, wherein the first viewpoint subject coincides with the rendering area of the graphic part;
• calculating first depth information of the graphic part in the stereoscopic image according to a relative position of the graphic part to the position of the first viewpoint subject;
• acquiring second and third depth information of the first viewpoint subject, the second depth information indicating a smaller depth than the first depth information and the third depth information indicating a greater depth than the first depth information;
• presenting a first alternative, a second alternative, and a third alternative for setting a depth of the graphic part in the stereoscopic image, the first alternative representing the first depth information, the second alternative representing the second depth information, and the third alternative representing the third depth information;
• and
• pasting the graphic part in the stereoscopic image according to a selection of one of the first alternative, the second alternative, or the third alternative, the graphic part not being originally included in the stereoscopic image in the acquiring.

An integrated circuit, comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the processor to perform operations including:
