ABSTRACT:
The present invention relates to a picture generator and a picture generation method. In detail the picture generator provides a mobile photograph device acquires first video data by photographing a performer in front of a predetermined background, a camera parameter calculator acquires the viewpoint of the photograph device, a first video data generator generates second video data corresponding to the projected picture of a predetermined object to which perspective transformation in a case viewed from the viewpoint of the photographing device acquired in the camera parameter calculator is applied, a data delay device acquires third video data by delaying the first video data corresponding to the processing time of the camera parameter calculator and the first video data generator, a first video data synthesizer acquires first synthetic video data by synthesizing the third video data and the second video data, a second video data synthesizer acquires second synthetic video data by synthesizing the first video data and the second video data, and a picture display that displays a picture for assisting the performance of the performer based upon the second synthetic video data. Hereby, a picture for assisting the movement of the performer is hardly delayed and the performer can readily perform.
