Abstract: In an apparatus for creating an all-around acoustic field, a producing section (4) is composed of a selecting section (41) for selecting one pair of right and left head transfer functions at an angle corresponding to an arriving direction of a reflected sound out of data of head transfer functions in whole directions stored in a storage section (5) on the basis of data of arriving directions of reflected sounds, an equalizing section (42) for equalizing a pair of right and left head transfer functions selected by the selecting section (41) by using frequency characteristic data of reflected sounds, a delaying section (43) for delaying the pair of right and left head transfer functions equalized by the equalizing section (42) by using delay time until a reflected sound arrives at a sound receiving point, and an adding section (44) for obtaining two channels of right and left impulse responses by accumulating the delayed pair of right and left head transfer responses.

Abstract: An object of the present invention is to precisely and stably detect a motion in an monitoring image, excluding effects of an illumination change and flicker. The frame division means divides an inputted X-th image frame F (X) into a plurality of blocks B(X)ij. Representative (e.g, average) luminance values BLrep (X)ij of block B (X) ij, a representative luminance value FLrep (X) of F (X), block luminance differences ΔBLrep (X)ij between the frame F (X) and a frame prior to F (X) and a frame luminance difference ΔFLrep (X) between the present frame F (X) and a frame prior to F (X) are calculated. Then, a certain block is determined to include a motion, if | ΔBLrep (X)ij−ΔFLrep (X) | for that certain block is greater than a prescribed threshold. The threshold may be adaptively changed in accordance with the luminance state.
