摘要：Provided are a portable input device for inputting coordinates, a method ofcalibrating the device, and a computer readable recording medium storing a computerprogram for making a computer perform the method. The portable input device includestwo digital cameras, a calibration tool, a storage section, and a controller for calculatingcoordinates of an object on an input surface based on images taken by the two digitalcameras based on images taken by the two digital cameras so as to include the
calibration tool. The controller also calibrates positions and widths of a detection bandwhich corresponds to a detection zone defined in a vicinity of the input surface. Thepositions and the widths of the detection band are stored in the storage section inrelationship to positions on the input surface.
