1. A three-dimensional shape input device for entering a three-dimensional shape of an object by a light projection method, the device comprising:

  • a light projecting portion for projecting detection light onto an object;

    an imaging portion for receiving reflected light from the object;

    a dividing portion for dividing an imaging surface of an image sensor into a plurality of areas;

    a storage portion for storing a plurality of calibration parameters corresponding to the respective areas;

    a computing portion for computing and determining the three-dimensional shape of the object by using image data delivered from the imaging portion and the calibration parameters; and

    wherein the computing portion computes and determines the three-dimensional shape for each of the areas by using the respective calibration parameter applied to each of the plurality of areas.
