Abstract

Computer processor hardware receives image data specifying element settings for each image of multiple original images in a sequence. The computer processor hardware analyzes the element settings across the multiple original images. The computer processor hardware then utilizes the element settings of the multiple original images in the sequence to produce first encoded image data specifying a set of common image element settings, the set of common image element settings being a baseline to substantially reproduce each of the original images in the sequence.

First claim

1 . A method comprising:
receiving first encoded image data derived from multiple original images in a sequence, the first encoded image data specifying settings for a set of common image elements to be used as a baseline for reproducing each of the multiple original images in the sequence; receiving second encoded image data specifying adjustments; and producing renditions of the multiple original images in the sequence via application of the adjustments to preliminary renditions of the multiple original images reconstructed based at least in part on the settings for the set of common image elements.

2 . The method as in claim 1 , wherein producing renditions of the multiple original images includes:
initially setting image elements in a first rendition of a first image of the multiple images to values based at least in part on the settings of the common image elements in the set; and initially setting image elements in a first rendition of a second image of the multiple images to values based at least in part on the settings of the common image elements in the set.

3 . The method as in claim 2 , wherein producing the renditions of the original images includes:
retrieving a first set of adjustment information from the second encoded image data, the first set of adjustment information indicating how to modify settings of the image elements in the first rendition of the first image; adjusting settings of the image elements in the first rendition of the first image as specified by the first set of adjustment information to reproduce a second rendition of the first image; retrieving a second set of adjustment information from the second encoded data, the second set of adjustment information indicating how to modify settings of the image elements in the first rendition of the second image; and adjusting settings of the image elements in the first rendition of the second image as specified by the second set of adjustment information to reproduce a second rendition of the second image.

4 . The method as in claim 1 , wherein the settings for the common image elements are derived from settings of image elements in the original images over two or more images in the sequence.

5 . The method as in claim 1 , wherein the settings for the set of common image elements correspond to one or more image renditions.

6 . The method as in claim 1 , wherein first encoded data comprises: first data indicating the settings for the common image elements and second data specifying operations to be used to reconstruct preliminary renditions of the multiple original images in the sequence based at least in part on the settings for the common image elements.

7 . The method as in claim 6 , wherein the information for each given preliminary image rendition comprises information that specifies what portion of the common element settings are processed to produce a preliminary image rendition for the given image.

8 . The method as in claim 6 further comprising:
applying a first set of image processing operations as specified by the second data to a first portion of the settings for the common image elements; and
applying a second set of image processing operations as specified by the second data to a second portion of the settings for the common image elements.

9 . The method as in claim 1 , wherein the settings for the set of common image elements defines attributes of objects in a single image frame.

10 . The method as in claim 9 , wherein the renditions of the multiple original images include a rendition of a first image and a rendition of a second image, the method further comprising:
deriving the rendition of the first image and the rendition of the second image from the single image frame.

11 . A system comprising:
computer processor hardware; a repository to store instructions associated with an application executed by the computer processor hardware; and an interconnect coupling the computer processor hardware and the repository, the computer processor hardware executing the instructions to:
receive first encoded image data derived from multiple original images in a sequence, the first encoded image data specifying settings for a set of common image elements to be used as a baseline for reproducing each of the multiple original images in the sequence;
receive second encoded image data specifying adjustments; and
produce renditions of the multiple original images in the sequence via application of the adjustments to preliminary renditions of the multiple original images reconstructed based at least in part on the settings for the set of common image elements.

12 . The system as in claim 11 , wherein the computer processor hardware is further operable to:
initially set image elements in a first rendition of a first image of the multiple images to values based at least in part on the settings of the common image elements in the set; and initially set image elements in a first rendition of a second image of the multiple images to values based at least in part on the settings of the common image elements in the set.

13 . The system as in claim 12 , wherein the computer processor hardware is further operable to:
retrieve a first set of adjustment information from the second encoded image data, the first set of adjustment information indicating how to modify settings of the image elements in the first rendition of the first image; adjust settings of the image elements in the first rendition of the first image as specified by the first set of adjustment information to reproduce a second rendition of the first image; retrieve a second set of adjustment information from the second encoded data, the second set of adjustment information indicating how to modify settings of the image elements in the first rendition of the second image; and adjust settings of the image elements in the first rendition of the second image as specified by the second set of adjustment information to reproduce a second rendition of the second image.

14 . The system as in claim 11 , wherein the settings for the common image elements are derived from settings of image elements in the original images over two or more images in the sequence.

15 . The system as in claim 11 , wherein the settings for the set of common image elements correspond to one or more image renditions.

16 . The system as in claim 11 , wherein first encoded data comprises: first data indicating the settings for the common image elements and second data specifying operations to be used to reconstruct preliminary renditions of the multiple original images in the sequence based at least in part on the settings for the common image elements.

17 . The system as in claim 16 , wherein the information for each given preliminary image rendition comprises information that specifies what portion of the common element settings are processed to produce a preliminary image rendition for the given image.

18 . The system as in claim 16 , wherein the computer processor hardware is further operable to:
applying a first set of image processing operations as specified by the second data to a first portion of the settings for the common image elements; and applying a second set of image processing operations as specified by the second data to a second portion of the settings for the common image elements.

19 . The system as in claim 11 , wherein the settings for the set of common image elements defines attributes of objects in a single image frame.

20 . The system as in clai
