1. A projection video display apparatus controllable by an operation to an operation object projected onto a projection surface, the projection video display apparatus comprising:

  • a projection unit that projects a display video onto the projection surface;

    an image capture unit that captures the projection surface;

    an operable region specifying unit that specifies each of a first region where the operation to the operation object is detectable and a second region where the operation to the operation object is undetectable in a range in which the display video is projected on the projection surface, based on image data captured by the image capture unit; and

    a detection unit that detects the operation to the operation object based on the image data captured by the image capture unit,wherein the projection unit can project a display video in which the first region where the operation to the operation object is detectable, which is specified by the operable region specifying unit, is displayed so as to be distinguished from the second region, and changes a display position of the operation object so that the operation object is displayed within a range of the first region where the operation to the operation object is detectable.
