Image correction device, image correction method, and program

An image correction method comprising steps of:

• acquiring a combined image including a plurality of partial images obtained by performing division imaging on a rectangular area in a real space using an imaging device;
• specifying a correction target area in the combined image corresponding to the rectangular area in the real space;
• dividing the correction target area into a plurality of divided areas;
• converting each of the plurality of divided areas into a rectangle, and
• displaying the acquired combined image on a display screen,
• wherein the specifying the correction target includes receiving, for the combined image displayed on the display screen, a designation indicating a vertex or a side in the combined image corresponding to a vertex or a side of the rectangular area in the real space, and specifying the correction target area in the combined image.

A non-transitory, computer-readable tangible recording medium which records a program for causing a computer to perform steps of:

• acquiring a combined image including a plurality of partial images obtained by performing division imaging on a rectangular area in a real space using an imaging device;
• specifying a correction target area in the combined image corresponding to the rectangular area in the real space;
• dividing the correction target area into a plurality of divided areas:
• converting each of the plurality of divided areas into a rectangle;
• and
• displaying the acquired combined image on a display screen,
• wherein the specifying the correction target includes receiving, for the combined image displayed on the display screen, a designation indicating a vertex or a side in the combined image corresponding to a vertex or a side of the rectangular area in the real space, and specifying the correction target area in the combined image.
