Abstract
Resolution progress of image sensor by digital signal processing was simulated on computer. By this method, high-resolution images that have high spacial frequency beyond the Nyquist frequency can be obtained. Simulated imaging device is an area image sensor. After the simulation, reproduced images that have frequency components twice higher than Nyquist frequency are successfully obtained. Using this method, it is possible to enhance the resolution of CCD image sensor twice as high as its inherent resolution.
