Light rays having passed through different regions in a pupil plane PP of a main lens 12 and having entered a micro-lens 14(0) of a micro-lens array 14 enter different light receiving cells 16(0, 1) to 16(0, 5), respectively, and are taken in an encoded aperture processing unit 80, as pixel data S(0, 1) to S(0, 5). The pixel data are generated as the pixel data of a weighted product-sum value S0, by a weighted product-sum calculating device U(0). The same process is performed for each micro-lens, and thereby, it is possible to obtain an image equivalent to an image when an encoded aperture pattern corresponding to weight coefficients is disposed on the pupil plane PP. |
