Abstract

A data-storage method includes capturing video data, identifying an object of which a high-resolution image is desired, the object being represented by a subset of the captured video data, compressing, to a first resolution, the subset of the captured video data, and compressing, to a second resolution, data of the captured video data other than the subset of the captured video data. According to the method, the first resolution is greater than the second resolution. The method further includes storing the compressed video data.

Claims

1. A data-storage method comprising:

capturing video data;

identifying an object of which a high-resolution image is desired, the object being represented by a subset of the captured video data;

compressing, to a first resolution, the subset of the captured video data;

compressing, to a second resolution, data of the captured video data other than the subset of the captured video data;

wherein the first resolution is greater than the second resolution; and

storing the compressed video data.

2. The data-storage method of claim 1, wherein the identifying step comprises:

obtaining location information corresponding to the object; and

identifying the subset of the captured video data using the location information.

3. The data-storage method of claim 1, wherein the identifying step comprises operation of a license-plate-location algorithm.

4. The data-storage method of claim 1, wherein the identifying step is performed responsive to user input.

5. The data-storage method of claim 1, wherein the location information comprises at least one set of coordinates.

6. The data-storage method of claim 5, wherein the at least one set of coordinates corresponds to corners of at least one vehicular license plate.

7. The data-storage method of claim 1, wherein the object comprises a face of an individual.

8. The data-storage method of claim 1, wherein the identifying step is performed via a fixed area of a display.

9. The data-storage method of claim 1, wherein the subset of the captured video data excludes chroma information.

10. An article of manufacture for data storage, the article of manufacture comprising:

at least one computer readable medium;

processor instructions contained on at least one computer readable medium, the processor instructions configured to be readable from the at least one computer readable medium by at least one processor and thereby cause the at least one processor to operate as to perform the following steps;

capturing video data;

identifying an object of which a high-resolution image is desired, the object being represented by a subset of the captured video data;

compressing, to a first resolution, the subset of the captured video data;

compressing, to a second resolution, data of the captured video data other than the subset of the captured video data;

wherein the first resolution is greater than the second resolution; and

storing the compressed video data.

11. The article of manufacture of claim 10, wherein the identifying step comprises:

obtaining location information corresponding to the object; and

identifying the subset of the captured video data using the location information.

12. The article of manufacture of claim 10, wherein the identifying step comprises operation of a license-plate-location algorithm.

13. The article of manufacture of claim 10, wherein the identifying step is performed responsive to user input.

14. The article of manufacture of claim 10, wherein the location information comprises at least one set of coordinates.

15. The article of manufacture of claim 14, wherein the at least one set of coordinates corresponds to corners of at least one vehicular license plate.

16. The article of manufacture of claim 10, wherein the object comprises a face of an individual.

17. The article of manufacture of claim 10, wherein the identifying step is performed via a fixed area of a display.

18. The article of manufacture of claim 10, wherein the subset of the captured video data excludes chroma information.
