Zusammenfassung:	Patterning device 114 modulates a light beam intensity distribution according to two-gradation first image data IMG1 having a first number of pixels. Processing device 130 calculates a correlation between detection intensity b based on output of photodetector 120 and m-gradation (m ≥ 2) random second image data IMG2 having a second number of pixels smaller than the first number, to generate a reconstructed image G(x,y) of an object. When the first and second image data IMG1 and IMG2 are scaled to the same size and overlapped, each pixel is associated with a pixel group including multiple pixels of the overlapping first image data IMG1. With the normalized gradation value of a given pixel as k, the number of pixels included in the pixel group as L, and the number of pixels having a value of 1 in the pixel group as 1, 1 = L x k holds true.
