This paper describes a new concept of active modulation image processing and also shows a simple real-time linear image processing apparatus based on this concept. The apparatus contains a vibrating mirror and a combination of the CCD image sensor camera and the video frame integrator, which are used as the image translator and the bipolar weighted integrator with object images, respectively. Experimental results with the Laplacian operation and image restoration under the basis of a pseudo-Wiener filter show that the present image processing technique has practical potential.
