METHOD APPARATUS FOR TRANSITIONING BETWEEN SEQUENCES OF IMAGES

A method and apparatus for generating and viewing a transition between a first and second sequence of images on a computer controlled display system. The method of the invention involves several steps, including: providing a first and second sequence of digitized images, which are typically stored in the computer system; providing the duration of total time of the transition between the first and second sequence of images; providing a resource means for specifying the transition between the first and second sequence; determining a first portion of the first sequence of images (the first portion having a duration in time less than or equal to the duration of the transition); determining a second portion of the second sequence (the second portion of the second sequence of images having a duration in time less than or equal to the duration of the transition); creating a transition template from the transition resource, the transition template having a duration equal to the transition; and combining the first portion of the first sequence and the second portion of the second sequence with the transition template to thereby produce a third sequence of images. The step of creating a transition template from the transition resource is further comprised of the steps of selecting objects, interpolating objects and/or a source image area and mapping objects to a source image area. In the combining step, the transition template is used to determine which portions of the first source sequence, the second source sequence, or both will be displayed in the third sequence of images. Also provided is a means for modifying a duration of the entire transition or for modifying a duration of individual frames within the transition.
