Abstract
Wide screen film frames are scanned in full width and in a first intermediate store a horizontal section of the frame is defined by a read-out start address and expanded by reading out at a lower speed. Only a part of the desired expansion is produced before the picture is stored for interlaced read-out in pairs of television fields. Thereafter the rest of the desired expansion is produced, with a further selection of the portion of each line to be viewed. Varying the read-out start address to shift the section of the picture to be reproduced in television form is done frame by frame in the first store and field by field in the second store and the two shift adjustments can be programmed in combination for smooth transitions.
