ABSTRACT:
A video processing system for use in creating apparent three dimensional movement of a two dimensional video image on a display screen 20. At least one set of axes is displayed on the image to be moved. A computer 24, in response to signals from a user operated stylus 21 and touch tablet 22, controls the manipulation of image data in an image store 26 to control apparent rotation of the image about, and/or linear movement along, an axis selected by the user. In the described embodiment several sets of linked axes are defined. Rotation or linear movement with respect to an axis is controlled respectively by selecting a marker identifying the axes or a line representing the axis. Selection is made by way of a cursor under the control of the stylus and touch tablet. The system can also display a line representing the user defined movement of e.g. the center of the image.
