1. An input device which switches between input modes according to an external input, said input device comprising:
- a coordinate input unit configured to identify input positions as the external input using coordinates, the input positions each being detected in response to proximity of an object to or pressure on an input surface defined by a two-dimensional coordinate system;
a coordinate-sequence storage unit configured to store, in a coordinate sequence including one or more sets of coordinates which represent coordinate points, one or more of the input positions identified by said coordinate input unit within a predetermined time; and
an input-mode determination unit configured to switch said input device to a geometric-figure input mode in the case where the number of the sets of coordinates included in the coordinate sequence is smaller than a predetermined number and the coordinate points are within a predetermined distance range, the geometric-figure input mode being a mode which allows inputting a ready-made geometric figure.

Abstract
An input-mode determination unit determines an input mode to be a graphic mode in the case where the number of sets of coordinates included in a coordinate sequence stored in the coordinate-sequence storage unit is smaller than a predetermined number and points represented by the coordinates are within a predetermined distance range, and otherwise, determines the input mode to be a curve mode. A line-to-draw sequence generation unit generates a line-to-draw sequence according to the input mode which the input-mode determination unit has determined to be.

9. A method of receiving an external input used in an input device switching between input modes according to the external input, the input device including a coordinate input unit, a coordinate-sequence storage unit, and an input-mode determination unit, said method comprising:
-
identifying, using the coordinate input unit, input positions as the external input using coordinates, the input positions detected in response to proximity of an object to or pressure on an input surface defined by a two-dimensional coordinate system; storing, in a coordinate sequence including one or more sets of coordinates which represent coordinate points, one or more of the input positions identified in said identifying within a predetermined time, the coordinate sequence being stored in the coordinate-sequence storage unit; and switching, using the input-mode determination unit, the input device to a geometric-figure input mode in the case where the number of the sets of coordinates included in the coordinate sequence is smaller than a predetermined number and the coordinate points are within a predetermined distance range, the geometric-figure input mode being a mode which allows inputting a ready-made geometric figure.
