Abstract

A reference image of one or more objects is displayed on the display of a mobile device in a manner that allows a user of the mobile device to simultaneously view the reference image and a preview image of the one or more objects currently in a field of view of a camera of the mobile device. An indication is provided to the user of the mobile device whether the camera of the mobile device is currently located within a specified amount of a distance at which the reference image was acquired. In response to a user request, the camera acquires a second image of the one or more objects and optionally a distance between the camera and the one or more objects at the time the second image was acquired is recorded. An image management application provides various functionalities for accessing and managing image sequences.

First claim

What is claimed is:

1. A mobile device comprising:
a camera;
a display;
one or more processors;
one or more memories communicatively coupled to the one or more processors; and
an image acquisition application executing on the mobile device, wherein the image acquisition application is configured to:
subsequent to acquisition of a reference image of one or more objects, cause the camera to automatically acquire a plurality of images of the one or more objects, wherein each image of the one or more objects, from the plurality of images of the one or more objects, is acquired using different exposure settings than the other images of the one or more objects, from the plurality of images of the one or more objects, and wherein the exposure settings for the plurality of images of the one or more objects are different than exposure settings used to acquire the reference image of the one or more objects, and a difference in the exposure settings for successive images, from the plurality of images, is based upon a user selection via the mobile device, wherein the reference image was acquired prior to the plurality of images of the one or more objects,
retrieve the reference image of the one or more objects, and
analyze the plurality of images of the one or more objects and determine one or more particular images of the one or more objects from the plurality of images of the one or more objects that best match the reference image of the one or more objects.

2. The mobile device of claim 1 , wherein the user selection via the mobile device specifies an exposure value step between successive images from the plurality of images.

3. The mobile device of claim 1 , wherein the exposure settings include one or more of an aperture setting, a shutter speed or an ISO setting.

4. The mobile device of claim 1 , wherein the exposure settings provide a range of exposures from dark to light.

5. The mobile device of claim 1 , wherein the image acquisition application is configured to analyze the plurality of images of the one or more objects and determine one or more particular images of the one or more objects from the plurality of images of the one or more objects that best match the reference image of the one or more objects using one or more of keypoint matching, histogram matching, keypoint+decision tree matching, hash-based matching, perceptual hash-based (phash) matching or feature-based matching.

6. The mobile device of claim 1 , wherein the image acquisition application is configured to:
generate, for the one or more particular images of the one or more objects, metadata that identifies the reference image, and
cause the one or more particular images of the one or more objects and the metadata that identifies the reference image of the one or more objects to be transmitted over one or more networks to an application server that is external to the mobile device.

7. The mobile device of claim 1 , wherein the image acquisition application is configured to cause the reference image of one or more objects to be displayed, on the display of the mobile device, as a background image in a manner that allows a user of the mobile device to simultaneously view one or more preview images of the one or more objects currently in a field of view of the camera by changing one or more attribute values for the reference image.

8. The mobile device of claim 1 , wherein the image acquisition application is configured to provide an indication to the user of the mobile device whether the camera is currently located within a specified amount of a distance at which the reference image was acquired by one or more of causing a visual indication to be displayed on the display of the mobile device or causing the mobile device to make one or more audible sounds.

9. A one or more non-transitory computer-readable media storing instructions which, when processed by one or more processors, causes:
an image acquisition application executing on a mobile device to:
subsequent to acquisition of a reference image of one or more objects, cause a camera on the mobile device to automatically acquire a plurality of images of the one or more objects, wherein each image of the one or more objects, from the plurality of images of the one or more objects, is acquired using different exposure settings than the other images of the one or more objects, from the plurality of images of the one or more objects, and wherein the exposure settings for the plurality of images of the one or more objects are different than exposure settings used to acquire the reference image of the one or more objects, and a difference in the exposure settings for successive images, from the plurality of images, is based upon a user selection via the mobile device, wherein the reference image was acquired prior to the plurality of images of the one or more objects,
retrieve the reference image of the one or more objects, and
analyze the plurality of images of the one or more objects and determine one or more particular images of the one or more objects from the plurality of images of the one or more objects that best match the reference image of the one or more objects.

10. The one or more non-transitory computer-readable media of claim 9 , the user selection via the mobile device specifies an exposure value step between successive images from the plurality of images.

11. The one or more non-transitory computer-readable media of claim 9 , wherein the exposure settings include one or more of an aperture setting, a shutter speed or an ISO setting.

12. The one or more non-transitory computer-readable media of claim 9 , wherein the exposure settings provide a range of exposures from dark to light.

13. The one or more non-transitory computer-readable media of claim 9 , wherein the image acquisition application is configured to analyze the plurality of images of the one or more objects and determine one or more particular images of the one or more objects from the plurality of images of the one or more objects that best match the reference image of the one or more objects using one or more of keypoint matching, histogram matching, keypoint+decision tree matching, hash-based matching, perceptual hash-based (phash) matching or feature-based matching.

14. The one or more non-transitory computer-readable media of claim 9 , further comprising additional instructions which, when processed by the one or more processors, cause the image acquisition application to:
generate, for the one or more particular images of the one or more objects, metadata that identifies the reference image, and
cause the one or more particular images of the one or more objects and the metadata that identifies the reference image of the one or more objects to be transmitted over one or more networks to an application server that is external to the mobile device.

15. The one or more non-transitory computer-readable media of claim 9 , wherein the image acquisition application is configured to cause the reference image of one or more objects to be displayed, on the display of the mobile device, as a background image in a manner that allows a user of the mobile device to simultaneously view one or more preview images of the one or more objects currently in a field of view of the camera by changing one or more attribute values for the reference image.

16. The one or more non-transitory computer-readable media of claim 9 , wherein the image acquisition application is configured to provide an indication to the user of the mobile device whether the camera is currently located within a specified amount of a distance at which
