PROBLEM TO BE SOLVED: To attain a display control device in which even when tempo input varies, smooth and natural motions are obtained in moving picture replay.SOLUTION: A CPU10 acquires a prediction time for a next tempo input in accordance with past tempo inputs; instructs, when a current tempo is input at a timing earlier than the acquired prediction time, a moving picture processing part 14 to generate interpolation frame data for interpolating a key frame Dn corresponding to current tempo input and a next key frame Dm in accordance with an interpolation ratio corrected to laten movement of moving picture display, and on the other hand, instructs, when a current tempo is input at a timing later than the prediction time, the moving picture processing part 14 to generate interpolation frame data for causing the movement of moving picture display to move reciprocatively by using a key frame Dm, having arrived after the prediction time during an excess period from the prediction time to the input of the current tempo, and precedent and subsequent key frames Dn,Dl centering around the key frame Dm. |
