The invention discloses a simple lens point spread function generation method. The method comprises the following steps of performing parametric modeling and generation on a single lens point spread function; the method comprises the steps of generating a star-shaped polygon, calculating vertex coordinates of the star-shaped polygon according to parameters, screening out a point set in the star-shaped polygon, carrying out modeling on point location energy, calculating point spread function energy distribution in the star-shaped polygon after an undetermined constant is determined, wherein the point location energy needs to meet the constraint that the sum of energy is 1, and obtaining a generated point spread function. According to the method, accurate parametric modeling and generation are carried out on the point spread function of the single lens, so that the generated point spread function better conforms to the characteristics of the single lens, a series of image processing technical characteristics ar
