Method for reading a recorded moving scene, in particular on a videodisk, and application of said method to driving simulators

摘要

In a method for reading a moving scene previously recorded in the form of successive images, the images are restituted by successive reading frames each corresponding to one image, the frames being intended to follow each other at a predetermined rate corresponding to a nominal speed of displacement of the moving scene. The method essentially consists:PPin defining an apparent speed at which the moving scene is required to travel,PPin automatically determining a function which expresses the ratio of the apparent speed V to the nominal speed Vnom by a number of recorded images to be skipped or to be repeated periodically at the time of reading,PPand in automatically initiating transfer from one image to another at each reading frame by a program which takes said function into account including a fractional portion of the number of images to be skipped or to be repeated at each reading frame.
