ABSTRACT:
A known method of generating intermediate pictures is based on an assumed linear interpolation of the positional change of corresponding objects in successive reference pictures. Such intermediate pictures, however, do not correspond to real pictures, notably when the reference pictures originate from a sensor moves along a curved path. In accordance with the invention the assignment of corresponding object points in successive reference pictures is subdivided so that the resultant assignment, starting from one reference picture, can be repeatedly performed on the successive intermediate pictures so that ultimately the next reference picture is obtained. Such an assignment algorithm produces faithful intermediate pictures also when the sensor is moved along a curved path.
