PROBLEM TO BE SOLVED: To provide an image projection apparatus configured to detect change of installation location of the apparatus without requiring special time and effort or cost, and to project an image by use of a correction parameter suitable for an installation environment. ! SOLUTION: An image projection apparatus 1 determines whether an installation location has been changed or not, on the basis of whether power supplied from the outside 100 has been cut off or is continued, and calculates a correction parameter according to a power supply state. When projection means 17 projects an image on a projection surface 110 for the first time after the start of supplying power from the outside 100, a control section 10 controls calculation means 35 to calculate a correction parameter, and controls image processing means 39 to correct the image on the basis of the correction parameter determined by the calculation means. When the power is continuously supplied from the outside after the projection means p |
