Abstract

PROBLEM TO BE SOLVED: To simplify animation generating work by generating new action data by connecting existent action data together. SOLUTION: Two arbitrary data which are 1st action data 5 and 2nd action data 6 are taken out of an animation data storage part 1. A connecting process part 3 finds interpolation data 9 by linearly interpolating frame data so as to obtain variation in a certain time from a final frame 7 to a start frame 8. The position of an animation image in each frame of the interpolation data 9 is found by interpolating the speeds of the 1st action data 5 and 2nd action data 6. With the found interpolation data 9, the 1st action data 5 and 2nd action data 6 are connected. The connected operation data are converted by a reproduction process part 2 into image data, which are displayed at a display part 4 or stored in the animation data storage part 1.

In order to achieve this object, the present invention provides an animation data storage means for fetching and storing motion data, and first and second arbitrary data transferred from the animation data storage means. By interpolating the frame data of the last frame of the first motion data and the start frame of the second motion data, interpolation data is created for the motion data of, and the first and second motion data are inserted by inserting the interpolation data. Combining processing means for creating combined operation data and transferring it to the reproduction processing means or animation data storage means, and reproduction processing means for converting the operation data transferred from the animation data storage means or combination processing means into image data, Display means for displaying the image data transferred from the reproduction processing means.

Further, the combining processing means, for the arbitrary first and second motion data transferred from the animation data storage means, includes an arbitrary number of frames from the last frame of the first motion data and the second motion data. The same number of pieces of frame data as the arbitrary number of frames from the start frame are combined in chronological order to create motion data in which the first and second motion data are combined.

Furthermore, the combining processing means deletes, from the arbitrary first and second motion data to be combined, the frames after the arbitrary frame of the first motion data, and further deletes the arbitrary frames of the second motion data. After deleting the frames before the frame, the operation data in which the first and second operation data are combined is created.

According to the above construction, the existing motion data from the animation data storage means can be combined by the combination processing means to create new motion data.
