Abstract

A method and image data acquisition service arrangement are disclosed that facilitate standardizing the process of adding metadata to acquired image information downloaded from a connected image capture device to a computer system. An image acquisition service analyzes image information downloaded from the image capture device and renders new metadata values based upon applied analytical algorithms/filters. Thereafter, the image information and new metadata are rendered available to other processes that use the image information and new metadata.

Claims

1. A method, in a computer system, for generating metadata based upon data contained within image information provided by an image capture device, the image information including image data suitable for processing by an image display application program to render a displayed image, the method comprising:

acquiring, by a data transfer interface, image information responsive to a request to acquire image data;

analyzing, by an image data analysis component associated with an image acquisition service, the acquired image information to render at least one new metadata value for the image information;

integrating the at least one new metadata value with the acquired image information;

converting, by a decoder associated with the image acquisition service, image data in a first format to image data in a second format; and

applying, during the analyzing step, at least one image recognition algorithm to the image data in the second format to render the at least one new metadata value.

2. The method of claim 1 wherein the analyzing step includes the sub-step of:

prompting a user to provide further information based upon a preliminary analysis of the image information to facilitate rendering the at least one new metadata value.

3. The method of claim 2 further comprising grouping, during the analyzing step, a set of temporally related images, and wherein the prompting step comprises requesting a descriptive label for the set of temporally related images.

4. The method of claim 2 further comprising detecting, during the analyzing step, a face within the image data and wherein the prompting step comprises requesting an identity corresponding to the face.

5. The method of claim 1 wherein the analyzing step comprises rendering the at least one new metadata value based upon header data contained within the acquired image information.

6. The method of claim 1 wherein the image data analysis component comprises a set of special-purpose image metadata generators.

7. The method of claim 6 further comprising selectively activating ones of the set of special-purpose image metadata generators prior to the analyzing step.

8. The method of claim 6 wherein a subset of the set of special-purpose image metadata generators includes default metadata generators that render a base set of metadata for each acquired image.

9. A computer-readable storage medium including computer-executable instructions for facilitating the generation of metadata based upon data contained within image information provided by an image capture device, the image information including image data suitable for processing by an image display application program to render a displayed image, the computer executable instructions facilitating performing a set of steps comprising:

invoking acquisition, by a data transfer interface, of image information in response to a request to acquire image data;

analyzing, by an image data analysis component associated with an image acquisition service, the acquired image information to render at least one new metadata value for the image information;

integrating the at least one new metadata value with the acquired image information;

converting, by a decoder associated with the image acquisition service, image data in a first format to image data in a second format; and

applying, during the analyzing step, at least one image recognition algorithm to the image data in the second format to render the at least one new metadata value.

10. The computer-readable storage medium of claim 9 wherein the analyzing step includes the sub-step of:

prompting a user to provide further information based upon a preliminary analysis of the image information to facilitate rendering the at least one new metadata value.

11. The computer-readable storage medium of claim 10 further comprising executable instructions for performing the step of grouping, during the analyzing step, a set of temporally related images, and wherein the prompting step comprises requesting a descriptive label for the set of temporally related images.

12. The computer-readable storage medium of claim 10 further comprising executable instructions for performing the step of detecting, during the analyzing step, a face within the image data, and wherein the prompting step comprises requesting an identity corresponding to the face.

13. The computer-readable storage medium of claim 9 wherein the image data analysis component comprises a set of special-purpose image metadata generators.

14. The computer-readable storage rriedium of claim 13 further comprising executable instructions for performing the step of selectively activating ones of the set of special-purpose image metadata generators prior to the analyzing step.

15. The computer-readable storage medium of claim 13 wherein a subset of the set of special-purpose image metadata generators includes default metadata generators that render a base set of metadata for each acquired image.

16. A method for integrating metadata into image data comprising:

instantiating at least an extensible portion of a set of metadata generation algorithms from DLLs or plugins associated with an image acquisition component;

obtaining, by the image acquisition component, interposed between a source of captured image data and a user mode process, image data from the source of captured image data;

rendering raw image data from the image data;

applying at least one of the metadata generation algorithms to the raw image data, in a non-interactive manner, to generate new metadata in response to one or more detected characteristics of images corresponding to the raw image data; and

storing the metadata in at least one metadata field associated with the image data.

17. The method of claim 16 further comprising the steps of:

receiving a request from the user mode process for the image data, and in response performing the obtaining step; and

providing at least one image data file including the image data and the new metadata to the user mode process.
