PROBLEM TO BE SOLVED: To provide an image projecting device capable of correcting the distortion of projection and reducing the calculation error of a transformation parameter by automatically measuring the coordinates of a screen. SOLUTION: This image projecting device is provided with a projection part 113 performing the projection to a projection surface 101, an image pickup part 102 picking up a measuring point, a projection designating point and an image, an image memory 106 for storing the picked up image, a mode input part 103, projection parameter estimation parts 107 to 110 estimating the coordinate transformation parameter of a screen/surface-to-be-projected, a projection designating point coordinate measuring part 111 measuring the coordinates of the projection designating point, a memory 112 for storing the transformation parameter and the coordinates of the projection designating point, a projected image storage part 116 for storing the projected image, a projected image selection part 114 selecting the optional projected image, an assumed projected image generation part 115 generating an assumed projected image and a screen/surface- to-be-projected coordinate transformation part 117 for transforming the assumed projected image to the image of a surface-to-be-projected coordinate system.
