Patent Images

1. A method for generating electronic representations of animated images from stored image data elements, comprising the steps of:

  • computing, from said stored image data elements, a first sequence of relatively low resolution frames representing animated images over a given time period and low pass filtering the information in said relatively low resolution frames;

    computing, from said stored image data elements, a second sequence of relatively high resolution frames representing said animated images over the given time period and high pass filtering the information in said relatively high resolution frames, the number of frames in said second sequence being less than the number of frames in said first sequence; and

    combining corresponding frames of said first and second sequences to obtain output high resolution frames representative of said animated images over said given time period.
