Generation system,generation method, and computer program

A generation method, comprising:

• causing a mark image including a prescribed mark to be displayed on a display screen of a display panel;
• capturing a plurality of partial images in each of which a part of the display screen is imaged with the mark image displayed on the display screen, and generating captured image data of the plurality of partial images;
• specifying, in each of the plurality of partial images, a target region within the partial image based on the mark included in the partial image;
• extracting, in each of the plurality of partial images, a target part corresponding to the target region from the captured image data of the partial image;
• and
• generating screen image data corresponding to captured image data of the whole display screen by synthesizing the target parts extracted.

A non-transitory computer readable storage medium recording thereon a computer program for execution by a computer, the computer program being configured to cause the computer to execute processing of:

• causing a mark image including a prescribed mark to be displayed on a display screen of a display panel;
• causing an imaging device to capture a plurality of partial images in each of which a part of the display screen is imaged with the mark image displayed on the display screen to generate captured image data of the plurality of partial images, and acquiring the generated captured image data of the plurality of partial images;
• specifying, in each of the plurality of partial images, a target region within the partial image based on the mark included in the partial image;
• extracting, in each of the plurality of partial images, a target part corresponding to the target region from the captured image data of the partial image;
• and
• generating screen image data corresponding to captured image data of the whole display screen by synthesizing the target parts extracted.
