Abstract
An image processing apparatus arranges an object in a virtual space of a display target, and establishes a view screen corresponding to a point of view. In tracing a ray passing through a pixel included in a figure of the object, in reference to a position P and an incident direction ω of the ray incident on the object, the image processing apparatus reads a previously acquired distribution of contribution ratios of a plurality of light sources representing the sizes of effects thereof on the color of the figure of the object, the plurality of light sources being in different directions relative to the object. The image processing apparatus determines a pixel value of the pixel by calculating a weighted sum of the luminance values of light from intrascene light sources based on the contribution values obtained with respect to the directions corresponding to the intra-scene light sources.
