<P>PROBLEM TO BE SOLVED: To provide a presentation device wherein a projected image and a handwritten image can be combined without misalignment. <P>SOLUTION: A pickup image acquisition section 105 acquires a handwritten image written on a projection image which is an image picked up with an image pickup means and projected on a projection board on which images can be written, and acquires an outside frame projection image indicating an area where an projection image which is an image picked up with the image pickup means and projected on the projection board can be projected. An image correction section 106 detects the coordinates of the outside frame of the handwritten image acquired by the pickup image acquisition section 105 by using the outside frame projection image acquired by the pickup image acquisition section 105, and corrects the position of the handwritten image by making the detected coordinates of the outside frame coincide with the coordinates of the outside frame of the outside frame image stored in an image storage section 104. An image composition section 107 creates a composite image by combining the handwritten image corrected by the image correction section 106 and a presentation image stored in the image storage section 104. <P>COPYRIGHT: (C)2007,JPO&INPIT |
