Abstract
In high definition or ordinary television transmission/reception systems, and picture recording systems, for example those utilizing a laser readable disk, and in general in digital picture processing systems a picture is divided into several parts and each picture part is examined for determining thereof--in the presence of a series of pictures (20, 21, 22) succeeding each other in time--a movement vector (V). If it is desired to create intermediate pictures (23, 24) should be created between the pictures initially available, it is possible that several different vectors exist, which all yield equivalent results for certain picture parts. In order to eliminate the ambiguity, for each equivalent movement vector (16) susceptible to being utilized to create an intermediate picture (24) the position (17) is determined, in which the picture part (25) concerned would be located in a preceding picture (23) if the movement vector should be applied to this picture part, and each time the difference between a movement vector utilized to arrive at the position (17) and the movement vector which had been determined for this position in the preceding picture (23) is calculated. The movement ve…
