An image processing device includes: an image probability model generation unit calculating a feature amount in units of local regions as division regions of a captured image of an imaging apparatus and generating an image probability model configured by the calculated feature amount, the image probability model indicating the generation probability of each noiseless pixel value; a memory storing a noise probability model generated from imaging element-dependent noise characteristic information, the noise probability model indicating the conditional probability of a given noised pixel value being generated in a case where a given noiseless pixel value is generated; and a Bayesian estimation unit generating a noise reduced image in which the noise of the captured image is reduced through a Bayesian estimation process in which the image probability model and the noise probability model are applied.
