Abstract
A method of storing image files in digital storage media begins by arranging a given set of image files into a composite image. A transformation may be applied to a given image file prior to being arranged into the composite image. A compression routine is then applied to the composite image, with the result then being stored in the digital storage media. This process reduces the amount of storage that would be otherwise required if the individual files were compressed and stored separately.
Claims8
A method of storing digital image files in digital storage media, comprising the steps of:
- dividing each of a set of digital image files into subcomponents;
- rating the subcomponents;
- performing given transformations on selected subcomponents of the image files;
- generating a composite image file from the subcomponents based at least partially on the subcomponents' rating;
- applying a given compression routine to the composite image file;
- and
- storing the composite image file as compressed.
A method of storing image files in digital storage media, comprising the steps of:
- responsive to a request to store an image file, dividing the image file into subcomponents;
- rating the subcomponents;
- performing given transformations on selected subcomponents of the image file;
- aggregating the subcomponents into a composite image file based at least partially on the subcomponents' rating;
- applying a given compression routine to the composite image file;
- and
- storing the composite image file as compressed.
In a digital camera having a digital storage medium and a compression routine for storing digital photographs in a compressed form in the digital storage medium, the improvement comprising:
- means for dividing each of a set of image files into subcomponents;
- means for rating the subcomponents;
- means for performing given transformations on selected subcomponents of the image files;
- and
- means for generating a composite image file from the subcomponents based at least partially on the subcomponents' rating;
- wherein the compression routine is applied to the composite image file.
