Abstract

Systems and method to increase blurriness of visual content may be based on user control, field-of-view, and/or changes in field-of-view. By adding or increasing blurriness at the periphery of the field-of-view, more attention may be drawn to unblurred sections.

Claims

1. A system for dynamically changing blurriness of visual content, the system comprising:

one or more physical processors configured by machine-readable instructions to;

obtain visual information that represents visual content;

determine a display field-of-view for playback of the visual content on a display, the display field-of-view including fields-of-view of the visual content to be presented during the playback, the display field-of-view including a change in the fields-of-view of the visual content such that the display field-of-view includes a first field-of-view of the visual content for a first period of playback and a second field-of-view of the visual content for a second period of playback subsequent to the first period of playback;

determine presentation information based on the visual information and the change in the fields-of-view of the visual content, wherein the presentation information represents modified visual content, the modified visual content including the visual content modified based on the change in the fields-of-view of the visual content, wherein;

(i) responsive to the first field-of-view being greater than the second field-of-view, at least a first portion of the visual content within the first field-of-view during the first period is modified in the modified visual content to increase blurriness, and

(ii) responsive to the second field-of-view being greater than the first field-of-view, at least a second portion of the visual content within the second field-of-view during the second period is modified in the modified visual content to increase blurriness; and

effectuate presentation of the modified visual content on the display based on the presentation information.

2. The system of claim 1, wherein increased blurriness is characterized by a reduction of one or both of acutance and contrast.

3. The system of claim 1, wherein the first portion of the visual content includes one or more peripheral sections of the visual content within the first field-of-view and the second portion of the visual content includes one or more peripheral sections of the visual content within the second field-of-view.

4. The system of claim 1, wherein increased blurriness is applied to the first portion of the visual content such that one or more levels of blurriness of the first portion of the visual content increase with increased distance from a focal point within the first field-of-field.

5. The system of claim 1, wherein increased blurriness is applied temporarily.

6. The system of claim 1, wherein increased blurriness is applied to mimic motion blur.

7. The system of claim 1, wherein the display is a two-dimensional display.

8. The system of claim 1, wherein the visual content includes wide-angled visual content.

9. The system of claim 1, wherein the change in the fields-of-view of the visual content is determined based on user input.

10. The system of claim 1, wherein the one or more physical processors are further configured to capture the presentation of the modified visual content on the display as video content.

11. A computer-implemented method to dynamically changing blurriness of visual content, the method being implemented on a computing platform that includes one or more physical processors configured by machine-readable instructions, the method comprising:

obtaining visual information that represents visual content;

determining a display field-of-view for playback of the visual content on a display, the display field-of-view acting including fields-of-view of the visual content to be presented during the playback, the display field-of-view including a change in the fields-of-view of the visual content such that the display field-of-view includes a first field-of-view of the visual content for a first period of playback and a second field-of-view of the visual content for a second period of playback subsequent to the first period of playback;

determining presentation information based on the visual information and the change in the fields-of-view of the visual content, wherein the presentation information represents modified visual content, the modified visual content including the visual content modified based on the change in the fields-of-view of the visual content, wherein;

(i) responsive to the first field-of-view being greater than the second field-of-view, modifying at least a first portion of the visual content within the first field-of-view during the first period in the modified visual content to increase blurriness, and

(ii) responsive to the second field-of-view being greater than the first field-of-view, modifying at least a second portion of the visual content within the second field-of-view during the second period in the modified visual content to increase blurriness; and

effectuating presentation of the modified visual content on the display based on the presentation information.

12. The method of claim 11, wherein increased blurriness is characterized by a reduction of one or both of acutance and contrast.

13. The method of claim 11, wherein the first portion of the visual content includes one or more peripheral sections of the visual content within the first field-of-view and the second portion of the visual content includes one or more peripheral sections of the visual content within the second field-of-view.

14. The method of claim 11, wherein increased blurriness is applied to the first portion of the visual content such that one or more levels of blurriness of the first portion of the visual content increase with increased distance from a focal point within the first field-of-field.

15. The method of claim 11, wherein increased blurriness is applied temporarily.

16. The method of claim 11, wherein increased blurriness is applied to mimic motion blur.

17. The method of claim 11, wherein the display is a two-dimensional display.

18. The method of claim 11, wherein the visual content includes wide-angled visual content.

19. The method of claim 11, wherein the change in the fields-of-view of the visual content is determined based on user input.

20. The method of claim 11, further comprising capturing the presentation of the modified visual content on the display as video content and storing the video content on electronic storage media.
