Abstract
Processing images of a scene taken with different focus includes, for each of at least some of the images, determining at least one portion of the image having a predetermined characteristic. A representation of the scene is generated that includes an array of elements, where each of at least some of the elements corresponds to a determined portion of at least one of the images. An element of the array is based on a correspondence between a distance associated with a determined portion of at least one image and a focused distance associated with at least one image. The generated representation is stored or provided as output.
Claims27
A method for processing images of a scene taken with different focus, comprising:
- for each of at least some of the images, determining at least one portion of the image having a predetermined characteristic;
- generating a representation of the scene comprising an array of elements, where each of at least some of the elements corresponds to a determined portion of at least one of the images, wherein an element of the array is based on a correspondence between a distance associated with a determined portion of at least one image and a focused distance associated with at least one image;
- and
- storing the generated representation or providing the generated representation as output.
A method for generating an image of a scene, comprising:
- receiving a first representation of the scene comprising a first array of elements that each represents an intensity for a given part of the scene;
- receiving a second representation of the scene comprising a second array of elements that each represents a distance to a given part of the scene;
- generating an image of the scene in which each portion of the generated image is based on an element from the first array and an element from the second array that represent substantially the same part of the scene;
- and
- storing the generated image or providing the generated image as output.
A computer-readable medium storing a computer program for processing images of a scene taken with different focus, the computer program comprising instructions for causing a computer system to:
- for each of at least some of the images, determine at least one portion of the image having a predetermined characteristic;
- generate a representation of the scene comprising an array of elements, where each of at least some of the elements corresponds to a determined portion of at least one of the images, wherein an element of the array is based on a correspondence between a distance associated with a determined portion of at least one image and a focused distance associated with at least one image;
- and
- store the generated representation or provide the generated representation as output.
A system, comprising:
- an image capture subsystem configured to capture images of a scene taken with different focus;
- and
- an image processing subsystem configured to,
- for each of at least some of the images, determine at least one portion of the image having a predetermined characteristic, and
- generate a representation of the scene comprising an array of elements, where each of at least some of the elements corresponds to a determined portion of at least one of the images, wherein an element of the array is based on a correspondence between a distance associated with a determined portion of at least one image and a focused distance associated with at least one image.
