Abstract
Methods and apparatus implementing image-sharpening profiles. In one aspect, the invention provides a method that includes creating an image-sharpening profile and storing the image-sharpening profile as a separate file external to any electronic image. An image-sharpening profile includes digital data encoding sharpening parameters. Sharpening parameters are control parameters for guiding the operation of an image-sharpening engine to provide a desired sharpening of an image.
Claims33
A method for specifying an image processing operation, comprising:
- creating an image-sharpening profile, the image-sharpening profile comprising digital data encoding sharpening parameters, the sharpening parameters being control parameters for guiding the operation of an image sharpening engine to provide a desired sharpening of an electronic image, wherein the image-sharpening profile is designed for a particular resolution, rendering device, or subject matter;
- associating the image-sharpening profile with a specific electronic image and at least one other electronic image;
- and
- storing the image-sharpening profile as a separate file external to any electronic image.
A method for specifying an image processing operation, comprising:
- creating an image-sharpening profile, the image-sharpening profile comprising digital data encoding sharpening parameters, the sharpening parameters being control parameters for guiding the operation of multiple image sharpening engines to provide a desired sharpening of an electronic image;
- and
- storing the image-sharpening profile as a separate file external to any electronic image.
A system, comprising:
- a collection of image-sharpening profiles, each image-sharpening profile comprising digital data encoding sharpening parameters, the sharpening parameters being control parameters for guiding the operation of an image sharpening engine to provide a desired sharpening of an electronic image, the collection including generic sharpening profiles designed to specify sharpening for different resolutions, different rendering devices, and different subject matters in an electronic image, and
- means for selecting an image-sharpening profile from the collection and associating the selected profile with an electronic image.
A method of processing image data, comprising:
- receiving an electronic image;
- obtaining an image-sharpening profile associated with the electronic image and at least one other electronic image, the profile being separate from and external to the electronic image, the profile comprising sharpening parameters, the sharpening parameters being control parameters for guiding the operation of an image sharpening engine to provide a desired sharpening for an electronic image, wherein the image-sharpening profile is designed for a particular resolution, rendering device, or subject matter;
- and
- providing the electronic image and the profile to a sharpening engine to sharpen the electronic image according to the image-sharpening profile.
A computer program product, tangibly stored on a computer-readable medium, for specifying an image processing operation, comprising instructions operable to cause a programmable processor to:
- create an image-sharpening profile, the image-sharpening profile comprising digital data encoding sharpening parameters, the sharpening parameters being control parameters for guiding the operation of multiple image sharpening engines to provide a desired sharpening of an electronic image;
- and
- store the image-sharpening profile as a separate file external to any electronic image.
