Image Adaptation With Target Size, Quality and Resolution Constraints
First Claim
Patent Images
1. A computer-implemented method for image adaptation, comprising:
- accepting a digitally-represented input image;
accepting a target size requirement; and
modifying the input image by reducing at least one of a resolution of the input image and a quality of the input image, the quality defining an amount of information allocated to represent each pixel value of the input image, so as to produce a compressed output image meeting the target size requirement.

Abstract
A computer-implemented method for image adaptation includes accepting a digitally-represented input image and a target size requirement. The input image is modified by optimally determining at least one of a resolution of the input image and a quality of the input image, the quality defining an amount of information allocated to represent each pixel value of the input image, so as to produce a compressed output image meeting the target size requirement.

31. A communication system, comprising:
-
one or more communication terminals, which are arranged to accept and display digitally-represented images; and a media adaptation server, which is arranged to accept a digitally-represented input image addressed to a destination terminal selected from the one or more communication terminals, to accept a target size requirement, to modify the input image by reducing at least one of a resolution of the input image and a quality of the input image, the quality defining an amount of information allocated to represent each pixel value of the input image, so as to produce a compressed output image meeting the target size requirement, and to send the compressed output image to the destination terminal. - View Dependent Claims (32)

33. A computer software product for image adaptation, the product comprising a computer-readable medium, in which program instructions are stored, which instructions, when read by a computer, cause the computer to accept a digitally-represented input image and a target size requirement, and to modify the input image by reducing at least one of a resolution of the input image and a quality of the input image, the quality defining an amount of information allocated to represent each pixel value of the image, so as to produce a compressed output image meeting the target size requirement.
