Patent ID: 8149917

Claim:
A method for calculating data representative of at least one intermediary transition image between a first image and a second image wherein the first and second images are represented by transform encoded data and each image having a plurality of locations associated with the transform encoded data, the method comprising: determining if the intermediary image will be intraframe or interframe encoded; for each corresponding location within the first and second image, calculating a transform coded value for the at least one intermediary image using the transform encoded data of the first and second images without transform decoding the transform encoded data; if the intermediary image is to be intraframe encoded, selecting an intraframe encoded equation for determining the transform coded value for the at least one intermediary image; if the intermediary image is to interframe encoded, selecting an interframe encoded equation for determining the transform coded values for the at least one intermediary image; and storing the transform coded values for the at least one intermediary image to memory.
