摘要： A moving picture coding/decoding apparatus capable of rapidly finding out a content of recorded moving picture data without completely decoding this moving-picture data content is constructed of an image coding/decoding unit (12) for coding/decoding a picture signal containing moving-picture information, a storage control unit (15), and a storage unit (16). In a small image generating unit (13), reduced resolution image signal (namely, "small image data") for indexing the original image signal is generated by sampling the image signal, or cutting out a portion of an image formed by the picture signal. This small image data is stored via the storage control unit (15) into the storage unit (16), while this small image data is correlated with the decoded image data obtained from the image coding/decoding unit (12). A selection is made of any one of the small image data read from the storage unit (16) and the restored image data derived from the image coding/decoding unit (12). Then, the selected image is displayed.
