An object of the present invention is to provide a simultaneous picture recording and reproducing method and apparatus capable of readily storing a plurality of simultaneous independent picture information and efficiently storing or reproducing information while continuously storing a new piece of independent picture information. <??>A simultaneous picture recording and reproducing method is characterized in: that a plurality of independent picture information (P1,P2), which are digitized and independent of each other, is stored in at least one of temporary storage means (12); that the independent picture information stored in the temporary storage means (12) and independent picture information inputted from outside are synthesized (10) in synchronization with each other to generate at least one of synthesized picture information; that, thereafter, the synthesized picture information is stored directly in a main storage means (15), or the synthesized picture information is subjected to a writing process (13) such as a compressing process and is stored in the main storage means (15), and also the synthesized picture information is read directly from the main storage means (15), or the synthesized picture information is subjected to a reading process (21) such as an extending process and is read from the main storage means (15); and that, thereafter, at least one of the independent picture information is extracted (22) and processed from the read piece of synthesized picture information and is reproduced (30). <IMAGE>
