We propose a Image mosaicing system which aim at lecture archiving. General image mosaicing method requires some restriction on the scene or camera. In the lecture scene, we can see one lecturer and some fixed planar objects. We use one fixed viewpoint pan-tilt camera for tracking lecturer, and use some fixed camera capturing planar objects. Captured images are warped to the same image coordinate with proper projection matrix. Expresimental result show some synthesized image which has wide view of angle and has high resoution on the region many people require high-resolution.
