Abstract
Image capturing data captured by using an imaging optical system including an iris with an aperture having no point symmetry is input. An imaging parameter for the imaging optical system when the image capturing data is captured is captured. A spectrum of the input image capturing data is calculated. Optical characteristic information corresponding to an imaging parameter and an object distance and a spectrum model are obtained. A predictive model is generated as a spectrum model corresponding to the input image capturing data by using the imaging parameter, optical characteristic information, and spectrum model. An evaluation function is generated by using the spectrum of the image capturing data and the predictive model. The actual distance of the object included in an image represented by the image capturing data is estimated by using the evaluation function and a statistical method.
