Zusammenfassung:	A technology capable of effectively and stably correcting brightness unevenness in an image obtained by imaging is provided. An image processing method includes an image obtaining step of obtaining an original image obtained by imaging an imaging object together with a substantially uniform background, an approximation step of specifying an approximation formula for approximating a two-dimensional luminance profile of the original image to a probability density function of a two-dimensional normal distribution, and a correction step of correcting a luminance value of each pixel constituting the original image on the basis of a luminance value of the two-dimensional luminance profile expressed by the approximation formula.
