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;

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, determining, by the computing device, that the master version of the selected image should be loaded into memory of the computing device based on a comparison of a first load time associated with the master version and a second load time associated with the preview version;

loading the master version of the image into the memory of the computing device; and

displaying the master version of the image.

2. The method of claim 1, further comprising:

determining that the first load time is less than the second load time multiplied by a coefficient; and

displaying the master version of the image based on the determination.

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

4. 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.

5. 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.

6. 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.

7. The method of claim 1, further comprising:

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

8. 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;

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, determining, by the computing device, that the master version of the selected image should be loaded into memory of the computing device based on a comparison of a first load time associated with the master version and a second load time associated with the preview version;

loading the master version of the image into the memory of the computing device; and

displaying the master version of the image.

9. The non-transitory computer-readable medium of claim 8, wherein the instructions cause:

determining that the first load time is less than the second load time multiplied by a coefficient; and

displaying the master version of the image based on the determination.

10. The non-transitory computer-readable medium of claim 8, wherein the instructions that cause displaying the master version include instructions that cause omitting loading the preview into memory of the computing device.

11. The non-transitory computer-readable medium of claim 8, 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.

12. The non-transitory computer-readable medium of claim 8, wherein the first load time and the second load time are determined based on measured load times associated with previously loaded images.

13. The non-transitory computer-readable medium of claim 8, 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.

14. The non-transitory computer-readable medium of claim 8, wherein the instructions cause:

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

15. 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 the system, a user selection of an image, the system storing corresponding thumbnail, preview and master versions of the image;

in response to the user selection, displaying on the display of the system the thumbnail version of the image;

after displaying the thumbnail version, determining, by the system, that the master version of the selected image should be loaded into memory of the system based on a comparison of a first load time associated with the master version and a second load time associated with the preview version;

loading the master version of the image into the memory of the system; and

displaying the master version of the image on the display.

16. The system of claim 15, wherein the instructions cause:

determining that the first load time is less than the second load time multiplied by a coefficient; and

displaying the master version of the image based on the determination.

17. The system of claim 15, wherein the instructions that cause displaying the master version include instructions that cause omitting loading the preview into memory of the computing device.

18. The system of claim 15, 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 15, 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 15, 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 15, wherein the instructions cause:

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