<P>PROBLEM TO BE SOLVED: To provide a scanning image projection apparatus that easily detects an operation instruction on a projection plane with simple processing and has excellent operation responsiveness. <P>SOLUTION: An image projection apparatus of the present invention includes: a projection part that projects an image on a projection plane by scanning a light beam emitted from a light source; and an image pickup part that picks up an image of the projection plane. The image projection apparatus obtains a picked-up image of the projection plane picked up by the image pickup part during the scanning projection of the image projected by the projection part, and changes a projection image projected by the projection part based on the picked-up image. <P>COPYRIGHT: (C)2012,JPO&INPIT |
