Abstract: A method and system of electronic image storage and display wherein the display is viewed on a raster scan TV display and the incoming signal comprises a sequence of scan lines whose line rate is lower than that of the horizontal TV line rate within a field of the TV display and is an odd integer submultiple thereof. The incoming signal is stored in the memory of a scan converter and the stored image is scanned and displayed on a conventional television raster scan display.The scan converter mode is alternated between read and write such that the writing is carried out during the time required to scan one horizontal TV line in the field and the reading is carried out during the time required to scan the next horizontal TV line in the field to thereby write and read on alternate horizontal lines of the same field.To produce a spatially uniform raster, the horizontal TV lines of alternate TV fields are offset by one line from the horizontal TV lines of the preceding field.
