STEREOSCOPIC IMAGE PLAYING METHOD, STEREOSCOPIC VOICE PLAYING METHOD, STEREOSCOPIC IMAGE PLAYING SYSTEM AND STEREOSCOPIC VOICE PLAYING SYSTEM

摘要

A stereoscopic image playing method according to one embodiment of the present invention comprises: an extraction step which extracts audio signals and 3D location information of an object from a stereoscopic image file; a determination step which determines a transmitting function corresponding to the 3D location information; a generation step which uses the transmitting function to generate a sound source signal which sounds as if a voice by the audio signals occurs in a place corresponding to the 3D location information; and a playing step which is synchronized with video signals of the stereoscopic image file to play the sound source signal. The video signal is a 3D image signal on a 3D space, and the 3D location information contains a space coordinate of the object contained in the 3D image signal on the 3D space. The sound source signal makes a sound pressure level in a location (hereafter, refers to ″acoustic focusing point″) corresponding to the space coordinate of the object contained in the 3D image signal on the 3D space be higher than a sound pressure level in an area except the acoustic focusing point. The acoustic focusing point is selected by a user. The acoustic focusing point is selected by the user, considering at least any one among the number of acoustically bright points, the controlling of locations of each point, and the controlling of strength of each point. The purpose of the present invention is to provide the stereoscopic image playing method, a stereoscopic voice playing method, a stereoscopic image playing system, and a stereoscopic voice playing system which randomly control a voice generating location in an audio and video space to be able to realistically play voices.;COPYRIGHT KIPO 2018
