Abstract
Abstract In a motion picture reproducing apparatus, or a motion picture recording and reproducing apparatus, an index picture storage means (33) stores a plurality of index pictures extracted from a series of motion pictures in time sequence at an assigned extraction timing in respective storage positions in a motion picture storage medium by associating each index picture with a different storage position. An index picture display means (25) arranges and displays the index pictures read from the index picture storage means on the display screen in time sequence. Selective means (7,23,24) select a desired target reproduction picture to be reproduced, and reproduction position control means (22,34) allow movement to a recording position corresponding to the selected target reproduction position to initiate a reproducing operation, thus allowing search conditions to be visually and intuitively determined when searching stored data on the motion picture storage medium, and providing substantially improved user-friendliness.
