The size of the image to be displayed is such that the virtual straight line and the intersection of one of the two diagonal lines of the rectangular display screen 111 and the display screen 111 divided into two by the virtual straight line. Among the vertices of the rectangular display screen 111 included on one side, the maximum size that can be entered within a range that does not change the aspect ratio within a rectangle (one side rectangle) passing through the vertex through which the one diagonal line passes It is. Further, when a virtual straight line extends in parallel with the coordinate axis of a two-dimensional coordinate system having a reference direction and a direction perpendicular to the reference direction as a coordinate axis, the virtual straight line is displayed on the other side of the display screen 111 divided into two by the virtual straight line. The size of the image to be displayed is such that the virtual straight line and the intersection of one of the two diagonal lines of the rectangular display screen 111 and the display screen 111 divided into two by the virtual straight line. Among the vertices of the rectangular display screen 111 included on the other side, the maximum size that can be entered within a range that does not change the aspect ratio within a rectangle passing through the vertex through which the one diagonal line passes (the other side rectangle) It is.
