Resolution Enhancement Using Multiple Apertures

This chapter develops very high definition image acquisition system which is based on the signal-processing approach with multiple cameras. The approach produces an improved resolution image with sufficiently high signal-to-noise ratio by processing and integrating multiple images taken simultaneously with multiple cameras. Originally, in this approach, we used multiple cameras with the same pixel aperture, but in this case there needs to be severe limitations both in the arrangement of multiple cameras and in the configuration of the scene, in order to guarantee the spatial uniformity of the resultant resolution. To overcome this difficulty completely, this chapter presents the utilization of multiple cameras with different pixel apertures, and develops a new, alternately iterative signal-processing algorithm available in the different aperture case. Experimental simulations and results are also presented. These results show that the utilization of multiple different-aperture cameras prospects well and that the alternately iterative algorithm behaves satisfactorily.
