IMAGE PROJECTION CONTROL DEVICE, CONFERENCE SYSTEM, AND CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To avoid a problem in which a correspondence relation between a document image and a handwritten image becomes unclear.

SOLUTION: An image projection control device comprises: an output part which outputs document image data to a projector to project a document image based on the document image data on a whiteboard; an input part which acquires scanned image data of a handwritten image written on a board surface on which the document image is projected, from the whiteboard; an image processing part which generates a composite image by composing the document image and the handwritten image on the basis of a positional relation between the projected document image and the board surface of the whiteboard; an operation part which receives an instruction to change a display mode of the document image: and a control part which when the instruction to change the display mode of the document image is given from the operation part, controls the input part to acquire the scanned image data from the whiteboard, in advance of the change of the display mode.
