PROBLEM TO BE SOLVED: To facilitate the editing of the shade of a cell tone image of a three-dimensional computer animated cartoon. SOLUTION: An inner-product operation part 18b computes the inner product of a normal line unit vector of the surface of an object of a key frame image and light source direction unit vector. An offset composing part 18c computes an offset value of an interpolation frame image which is interpolated and generated on the basis of a result of edition of a shade by a shade inputting part 23. An interpolation and generation part 18a interpolates and generates the basic image of an interpolation frame image from the key frame image. A threshold value determination part 18d judges which is larger, a luminance value defined as the sum of the inner product and offset value or a prescribed threshold value. An image generation part 18e adds shades to pixels on the interpolation frame images, the pixels corresponding to the respective positions of the surface of the object in a three-dimensional space, on the basis of the result of the judgement. The present invention can be applied to an animated cartoon editing device. COPYRIGHT: (C)2009,JPO&INPIT |
