Abstract
A high definition video signal can be obtained from photographic film by a non-real time scanning operation. The image area to be scanned is divided into blocks and a number of subscans equal to the number of pixels in each block are performed on the image area. In each scan, a different pixel in each block is scanned so that after n scans all pixels in the n pixel blocks have been scanned and a composite video signal can be formed. A plurality of high definition frames are stored at less than real time in a multi-frame store and then read out in real time to give a continuous high definition playback.
