Abstract
Official abstract text for this publication.
An image processing apparatus. The image processing apparatus may perform filtering to emphasize a surface lighting of a low frequency band from an input lighting environment image, and may also perform at least one virtual point light (VPL) sampling from the input lighting environment image. The image processing apparatus may perform precomputed radiance transfer (PRT) based rendering using the filtered lighting environment image and VPL based rendering using the sampled VPL.
First claim
Opening claim text (preview).
What is claimed is: 1. An image processing apparatus comprising: a processor to control one or more processor-executable units; a filtering unit to filter an input lighting environment image, to thereby generate a filtered lighting environment image in which a low frequency component of the input lighting environment image is extracted, wherein the input lighting environment image comprises a plurality of pixels comprising information about a color of a light; a precomputed ra…
