A scroll display control device is provided, which is capable of scroll-displaying a text corresponding to a picture in such manner that the text can be easily understood. The scroll display control device scroll-displays, in synchronism with reproduction of the picture correlated to text information (TI), the corresponding text information (TI) on a text display screen (TW). A scroll speed calculation unit (102) dynamically calculates a text scroll speed (v) on the basis of a time length of a picture section presently under reproduction, a text quantity of the corresponding text section and text display setting information. A picture text control unit (104) scroll-displays text of the text section at a predetermined reference position of the text display screen (TW) according to the scroll speed (v). By displaying preceding and succeeding texts with respect to the text corresponding to the picture section presently under reproduction, it is possible to read back and pre-read. |
