Equipment and method for data retrieving

Abstract: PURPOSE: To simplify user's instruction operation and to easily find desired data by displaying representative data and designating a retrieval range by a user. CONSTITUTION: A scroll bar display 21 is used to set an initial frame retrieval range by the user. In a window display are Q, a predetermined number (e.g. 10) of reduced frames 23, i.e., representative frames, and a start-point icon 22A and an end-position 22B are displayed. All data to be retrieved are divided into 10 and the frames positioned at the division positions are read out of a file storage device and reduced with the indication of a CPU for a frame 23. Each frame 23 indicates a division position in the currently set retrieval range, so the icon 22A and 22B and representative frames are selectively used for the range specification of retrieval. Then the user reduces the retrieval range by using a representative screen on a display screen and can retrieve a desired frame.
