| description | PROBLEM TO BE SOLVED: To easily obtain a composite image of high picture quality by performing the coordinate transformation of a key signal based on an object image area and generating the shadow of an object to be composited with an image. SOLUTION: The camera data on the positions and directions of the intra-studio three-dimensional coordinates and the picture angle information on a studio camera 3 and a light source camera 24 are detected based on the camera data detection information 13 and inputted to a generation device. The generation device calculates the specific coordinates included in a three-dimensional model that is projected into an optional pixel contained in an image of the camera 3 based on the position and the picture angle information of the camera 3 and also on the inputted three-dimensional shape and layout data. Then the generation device calculates a specific pixel of the camera 24 where the coordinates included in the three-dimensional model are projected. By means of such a coordinate transformation processing, a key signal of a shadow which follows an object and has no three-dimensional conflict is produced and the conversion processing is carried out so as to secure the position and shape of the shadow to be added. Thus, a shadow key signal is produces and inputted to a compositing device 9. |
