Abstract
An image processing device includes a photon map generator that constructs a virtual three-dimensional space as a rendering target and generates a photon map by distributing photons used for a photon mapping method, a low-luminance region identifying unit that identifies a low-luminance region estimated to have low luminance when the virtual three-dimensional space is projected onto a screen corresponding to a viewpoint by a method different from the photon mapping method, and a rendering part that collects photons corresponding to all pixels based on the photon map with reduction in the collection rate of photons corresponding to a pixel included in the low-luminance region compared with the other region, and calculates radiance to decide a pixel value and generate a display image.
