  • Publication number: 20220132022
    Abstract: Patterning device modulates a light beam intensity distribution according to two-gradation first image data having a first number of pixels. Processing device calculates a correlation between detection intensity b based on output of photodetector and m-gradation (m?2) random second image data 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 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. 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 l, l=L×k holds true.
