THREE-DIMENSIONAL IMAGE PROCESSOR

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional image processor with which retrieval omission is suppressed while the number of pixel retrieving times is reduced and a retrieving speed is improved. SOLUTION: A temporary surface 61 of an accumulated three-dimensional image is detected, the retrieval range of object pixels from a viewpoint to the detected temporary surface 61 is variably set, and the object pixels are retrieved on the basis of the retrieval range.
