A method is disclosed for recording picture information, in which pictures (2) on an image carrier (3) are scanned and converted into a picture information signal, the picture information signal being converted into a coded picture, which is recorded on a record carrier (184). For a plurality of scanned pictures the information signal is converted into n independently coded pictures (TV/ 16, TV/4, TV) for each picture scanned, n being greater than or equal to two. The resolutions of the picture representations defined by these n coded pictures are different. For each of said plurality of scanned pictures (2) the associated coded pictures (TV/16, TV/4 TV) are recorded on the record carrier (184). Moreover, a picture retrieval and reproduction device (11) for reading the record carrier (184) thus obtained is disclosed.
