IMAGE PROCESSING METHOD, APPARATUS FOR GENERATING OUTPUT IMAGE INFORMATION WHICH USED PICKUP PRESENTATION IMAGE INFORMATION AND COMPUTER READABLE RECORD-MEDIUM ON WHICH PROGRAM FOR EXECUTING METHOD THEREOF

摘要

An image processing method for generating output image information by using photographed presentation image information, a method thereof and a recording medium at which a program for executing the method is recorded are provided to enable a user to reflect a mark indicated by a laser beam generated not by a mouse operation but a laser pointer while a user is advancing a presentation by using the laser pointer. An image process apparatus sets up basic image information(S310), and obtains photographing image information by photographing a presentation image irradiated onto a screen(S320). The image process apparatus compares the photographing image information with predetermined basic image information(S330), and judges whether or not there is the difference of a pixel based on the comparison result(S340). If so, the image process apparatus creates changing information(S350), and generates output image information by using the changing information(S360). The image process apparatus transmits the created output image information to a computer or a projector connected to the computer(S370).
