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 increasing blurriness of visual content captured in the real world, the system comprising:

a display configured to present images; and

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

obtain visual information that represents visual content, wherein the visual content has been captured in the real world by one or more image sensors;

determine a display field-of-view within the visual content to be presented on the display during playback of the visual content, the display field-of-view acting as a viewfinder into the visual content, the display field-of-view including a first field-of-view of the visual content during a first period of playback;

receive input that defines a modification of the display field-of-view, the modification of the display field-of-view defining a change of the display field-of-view from including the first field-of-view of the visual content during the first period of playback into including a second field-of-view of the visual content during a second period of playback, wherein the second field-of-view of the visual content is to be presented on the display during the second period of playback, wherein the second period is subsequent to the first period;

determine presentation information based on the visual information and the modification of the display field-of-view, wherein the presentation information represents modified visual content, the modified visual content including the visual content modified based on the modification of the display field-of-view, 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, and wherein the images are two-dimensional images.

8. The system of claim 1, wherein the visual content includes spherical video content.

9. The system of claim 1, wherein the input that defines the modification is user input received from a user associated with a client computing platform.

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.

20. The method of claim 1, 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.

11. A computer-implemented method to increase blurriness of visual content captured in the real world, 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, wherein the visual content has been captured in the real world by one or more image sensors;

determining a display field-of-view within the visual content to be presented on a display during playback of the visual content, the display field-of-view acting as a viewfinder into the visual content, the display field-of-view including a first field-of-view of the visual content during a first period of playback;

receiving input that defines a modification of the display field-of-view, the modification of the display field-of-view defining a change of the display field-of-view from including the first field-of-view of the visual content during the first period of playback into including a second field-of-view of the visual content during a second period of playback, wherein the second field-of-view of the visual content is to be presented on the display during the second period of playback, wherein the second period is subsequent to the first period;

determining presentation information based on the visual information and the modification of the display field-of-view, wherein the presentation information represents modified visual content, the modified visual content including the visual content modified based on the modification of the display field-of-view, 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 images are two-dimensional images.

18. The method of claim 11, wherein the visual content includes spherical video content.

19. The method of claim 11, wherein the input that defines the modification is user input received from a user associated with a client computing platform.
