PROBLEM TO BE SOLVED: To provide a projection imaging apparatus capable of efficiently and easily recording a content added to a projected plane where an image is projected.SOLUTION: A projection imaging apparatus comprises: a projection part 71 which projects an image based upon first image data; an imaging part 72 which photographs an image projection region where the image is projected by the projection part 71; a storage part 73 which records the image photographed by the imaging part 72 as second image data; and a control part 75 including a determination part 75b which compares the first image and the second image with each other and determines differences between the first image data and second image data, and the control part 75 saves at least different parts of the second image data in the storage part 73 when the determination part 75b determines that the first image data and second image data have differences, and discards the second image data when the determination part 75b determines that the first image data and second image data have no difference.SELECTED DRAWING: Figure 1 |
