Abstract

Adaptive loading of images is described. In some implementations, the process of loading of images by a computing device can be adapted to account for image size, image load times and/or user behavior. In some implementations, the process of preloading of images can be adapted to account for image size and/or user behavior. In some implementations, presentation of an image loading indicator can be adapted to account for image size and/or amount of time required to load an image.

Claims

1. A method comprising:

receiving, by a computing device, a user selection of an image, the computing device storing corresponding thumbnail, preview and master versions of the image, wherein the preview version of the image is designated for loading before the master version of the image is loaded;

in response to the user selection, displaying on a display of the computing device the thumbnail version of the image;

after displaying the thumbnail version and prior to loading either the master version or the preview version, determining, by the computing device, that a first load time associated with the master version is less than a threshold load time, the threshold load time based on a second load time associated with the preview version, and, in response, determining that the master version of the selected image should be loaded into memory of the computing device instead of the preview version;

responsive to determining that the master version of the selected image should be loaded into memory of the computing device instead of the preview version, loading the master version of the image into the memory of the computing device instead of the preview version; and

displaying the master version of the image instead of the preview version,

wherein the threshold load time comprises the second load time multiplied by a coefficient, and wherein the threshold load time is different than the second load time.

2. The method of claim 1, wherein displaying the master version includes omitting loading the preview version into memory of the computing device.

3. The method of claim 1, wherein loading the master version includes loading the master version when the first load time is less than a maximum load time.

4. The method of claim 1, wherein the first load time and the second load time are determined based on measured load times associated with previously loaded images.

5. The method of claim 1, further comprising:

delaying the loading of the master version based on an expected dwell time, where the expected dwell time is determined based on the amount of time that each of a previous number of images were displayed.

6. The method of claim 5, wherein determining the expected dwell time comprises determining an average amount of time the user has dwelled on a previous number of images.

7. The method of claim 6, comprising comparing the expected dwell time to the first load time associated with the master version and an the second load time associated with the preview version to determine whether the master version, the preview version, or neither can be loaded within the expected dwell time, and in response, choosing the master version, the preview version, or neither for loading.

8. The method of claim 1, further comprising:

delaying the loading of the master version based on the first load time associated with the master version of the image, where the first load time is determined based on the amount of time that the computing device took to load each of a previous number of images.

9. The method of claim 1, wherein the master version comprises a higher resolution than the preview image.

10. A non-transitory computer-readable medium including one or more sequences of instructions which, when executed by one or more processors, causes:

receiving, by a computing device, a user selection of an image, the computing device storing corresponding thumbnail, preview and master versions of the image, wherein the preview version of the image is designated for loading before the master version of the image is loaded;

in response to the user selection, displaying on a display of the computing device the thumbnail version of the image;

after displaying the thumbnail version and prior to loading either the master version or the preview version, determining, by the computing device, that a first load time associated with the master version is less than a threshold load time, the threshold load time based on a second load time associated with the preview version, and, in response, determining that the master version of the selected image should be loaded into memory of the computing device instead of the preview version;

responsive to determining that the master version of the selected image should be loaded into memory of the computing device instead of the preview version, loading the master version of the image into the memory of the computing device instead of the preview version; and

displaying the master version of the image instead of the preview version,

wherein the threshold load time comprises the second load time multiplied by a coefficient, and wherein the threshold load time is different than the second load time.

11. The non-transitory computer-readable medium of claim 10, wherein the instructions that cause displaying the master version include instructions that cause omitting loading the preview version into memory of the computing device.

12. The non-transitory computer-readable medium of claim 10, wherein the instructions that cause loading the master version include instructions that cause loading the master version when the first load time is less than a maximum load time.

13. The non-transitory computer-readable medium of claim 10, wherein the first load time and the second load time are determined based on measured load times associated with previously loaded images.

14. The non-transitory computer-readable medium of claim 10, wherein the instructions cause:

delaying the loading of the master version based on an expected dwell time, where the expected dwell time is determined based on the amount of time that each of a previous number of images were displayed.

15. The non-transitory computer-readable medium of claim 10, wherein the instructions cause:

delaying the loading of the master version based on the first load time associated with the master version of the image, where the first load time is determined based on the amount of time that the computing device took to load each of a previous number of images.

16. A system comprising:

one or more processors;

a display; and

a non-transitory computer-readable medium including one or more sequences of instructions which, when executed by one or more processors, causes;

receiving, by a computing device, a user selection of an image, the computing device storing corresponding thumbnail, preview and master versions of the image, wherein the preview version of the image is designated for loading before the master version of the image is loaded;

in response to the user selection, displaying on a display of the computing device the thumbnail version of the image;

after displaying the thumbnail version and prior to loading either the master version or the preview version, determining, by the computing device, that a first load time associated with the master version is less than a threshold load time, the threshold load time based on a second load time associated with the preview version, and, in response, determining that the master version of the selected image should be loaded into memory of the computing device instead of the preview version;

responsive to determining that the master version of the selected image should be loaded into memory of the computing device instead of the preview version, loading the master version of the image into the memory of the computing device instead of the preview version; and

displaying the master version of the image instead of the preview version,

wherein the threshold load time comprises the second load time multiplied by a coefficient, and wherein the threshold load time is different than the second load time.

17. The system of claim 16, wherein the instructions that cause displaying the master version include instructions that cause omitting loading the preview version into the memory of the system.

18. The system of claim 16, wherein the instructions that cause loading the master version include instructions that cause loading the master version when the first load time is less than a maximum load time.

19. The system of claim 16, wherein the first load time and the second load time are determined based on measured load times associated with previously loaded images.

20. The system of claim 16, wherein the instructions cause:

delaying the loading of the master version based on an expected dwell time, where the expected dwell time is determined based on the amount of time that each of a previous number of images were displayed.

21. The system of claim 16, wherein the instructions cause:

delaying the loading of the master version based on the first load time associated with the master version of the image, where the first load time is determined based on the amount of time that the system took to load each of a previous number of images.

22. A method comprising:

receiving, by a computing device, a user selection of an image, the computing device storing corresponding preview and master versions of the image, wherein the preview version of the image is designated for loading before the master version of the image is loaded;
