Title:
METHOD FOR GENERATING PICTURE
Document Type and Number:
Japanese Patent JP3538263
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To synthesize an actual animation image and a picture obtained by computer graphics so as not to reduce the quality of a final moving image.
SOLUTION: Two-dimensional (2D) coordinates of respective feature points of an actual animation image which are time-sequentially calculated by a feature point extracting part 103 are smoothed by a correction part 104. A three- dimensional (3D) coordinate calculating part 105 sets up the 3D coordinates of respective feature points and the visual point parameters of respective frames from the 2D coordinates. A 3D model generating part 106 generates a virtual mask from the 3D shape of the actual animation image determined by the 3D coordinates. A picture generating part 107 arranges a mask object in virtual 3D space and a picture synthesizing part 108 arranges a CG model. The visual point determined by the calculating part 105 is perspectively projected to a screen coordinate system, a subject image in the actual animation image is reproduced on the position of the mask on a perspective projection drawing and the visual point is corrected. Thus a synthetic picture is displayed on a display device 100.
