Paper Abstract

I have developed for cameras a new system of capturing images called the "optical-multiplex" system. The system is comprised of an image sensor and a multi-lens array (or an array of pin holes). This system has the advantages of being compact and light and being able to provide a deep depth of field. In a model of the system for simulation purposes, light passes through five pin holes in an "aperture sheet" and the resulting object information is detected by the image sensor and processed by the signal-processing unit, which outputs the "optical-multiplex" signal. The simulation model incorporating both signal and noise shows that most pixels in this new system have a better signal-to-noise ratio than in the conventional single-lens system.
