Moving-image processing device, moving-image processing method, and information recording medium

Abstract

Provided is a moving-image processing device for determining interference between objects. A moving-image processing device () determines whether a first object drawn in a first moving image clashes with a second object drawn in a second moving image. The first moving image is accompanied by a first anterior-surface depth for the first object. The second moving image is accompanied by a second anterior-surface depth for the second object. A rear-surface depth acquirer () acquires a first rear-surface depth for the first object, and a second rear-surface depth for the second object. A clash determiner () functioning as an interference determiner determines whether the first object interferes with the second object in certain frames, on the basis of the overlapping of a first occupancy zone spanning from the first anterior-surface depth to the first rear-surface depth and a second occupancy zone spanning from the second anterior-surface depth to the second rear-surface depth, the first and second occupancy zones being in an overlap area present in cases when a first drawing area where the first object is to be drawn overlaps a second drawing area where the second object is to be drawn.
