A correction data generation device specifies, for each of the plurality of partial images captured by the capturing device, an object area in the partial image on the basis of the mark included in the partial image. The correction data generation device extracts, for each of the plurality of partial images, an object portion that corresponds to the object area from the capture data of the partial images, and synthesizes a plurality of extracted object portions, thereby generating screen image data that corresponds to the capture data of the entire display screen. ## Claims ### Claim 1 A generation system, comprising: a display control section configured to cause a mark image including a mark to be displayed on a display screen of a display panel, the mark having a prescribed shape and indicating a position of a boundary of a target region in an image;
