1. A display input device comprising:
a display section that displays an object;
a touch panel section for detecting a touch operation, the touch panel section being disposed at the display section; and
a control section that detects a touch operation based on an output from the touch panel section,
wherein,
on detecting that a mode switching operation has been performed on the touch panel section while the object is being displayed, the mode switching operation being a touch operation in which touches at a first position and a second position on the touch panel section overlap in time and then, while the touch at the second position is maintained, the touch at the first position different from the second position is released, the control section makes a shift to a rotation mode or to an enlargement/reduction mode,
in a case where a shift has been made to the rotation mode, when a display changing operation is performed on the touch panel section, the display changing operation being a touch operation in which a touch is newly made on a third position on the touch panel section separately from the touch at the second position and then the second or third position is moved, the control section makes the display section perform a rotation display in which the object is rotated according as the second or third position is moved, the control section making the display section increase a rotation angle of the object per unit movement amount of the second or third position according as a distance between the first and second positions in the mode switching operation is larger, and
in a case where a shift has been made to the enlargement/reduction mode, when the display changing operation is performed on the touch panel section, the control section makes the display section perform an enlargement/reduction display in which the object is enlarged or reduced according as the second or third positions is moved, the control section making the display section increase an enlargement amount or a reduction amount of the object per unit movement amount of the second or third position according as the distance between the first and second positions in the mode switching operation is larger.
