Abstract: An image interpolator for converting an original image into an enhanced image, the interpolator including rule logic for embodying a rule specifying how pixel patterns associated with first subband image data transform into corresponding pixel patterns associated with second subband image data, the first and second subband image data being derived from a reference image; and conversion logic for generating the enhanced image from the original image based upon the rule.

Family: Show 2 known family members
First Claim:
Show all 36 claims		 What is claimed is:     1. An image interpolator for converting an original image into an enhanced image, the interpolator comprising:
  • rule logic for embodying a rule specifying how pixel patterns associated with first subband immage data transform into corresponding pixel patterns associated with second subband image data, said first and second subband image data being spatial frequency subband image data derived from a reference image that is generated by a single sensor; and
  • conversion logic for generating the enhanced image from the original image based upon said rule, wherein said conversion logic comprises:
  • means for generating high resolution subband image data from the second subband image data in accordance with said rule; and
  • means for combining the original image with the high resolution image data to generate the enhanced image.
