PURPOSE:To enable dynamic representation without generating image data in the middle of deformation by varying the threshold value for the binary coding of gradation data in order, and cutting, composing, and wiping still image data and stereoscopic logotype image data in order with respective mask data which are generated as to respective threshold values. CONSTITUTION:A means 34 varies the threshold value of the binary coding of the gradation data in order, and cuts, composes, and wipes the still image data and stereoscopic logotype image data in order with the respective mask data generated by a binary-coding part 32 for the respective threshold value. Thus, the gradation data are converted into binary data with the threshold value which varies in order to generate the mask data which vary stepwise, and the mask data are used to cut and compose the still image data and shadowed stereoscopic logotype image data in order, thereby representing logotype image data dynamically. |
