PROBLEM TO BE SOLVED: To provide a projection device capable of improving the degree of freedom at distortion correction.SOLUTION: A CPU 19 acquires a relative angle between a projector 1 and a screen 2 by, for example, an attitude sensor 23, and based on the acquired relative angle, calculates the number of output pixels to be recommended to a PC 4 to notify the PC 4 of the number of output pixels. The CPU 19 then performs the distortion correction and the projection of an image signal output from the PC 4 according to the notified number of output pixels, on the basis of the relative angle. |
