Abstract

Techniques for displaying content on a display to reduce screenshot quality are described herein comprising generating a set of degradation frames based on a source frame, with each degradation frame in the set of degradation frames based on applying one or more alterations to the data in the source frame based on a set of degradation parameters. A frame display order is determined and at least a subset of the degradation frames is displayed, corresponding to the frame display order.

Claims

1. A computer-implemented method, comprising:

determining a set of degradation parameters based at least in part on content configured for displaying on a display;

calculating, based at least in part on a first subset of the set of degradation parameters, a number of degradation frames;

generating the number of degradation frames to obtain a set of degradation frames comprising multiple degradation frames such that each degradation frame of the set of degradation frames at least comprises degradation frame content, the degradation frame content at least including non-degraded content corresponding to at least a part of the content, the degradation frame content further at least including degraded content based at least in part on a second subset of the set of degradation parameters;

determining a frame display order based at least in part on a third subset of the set of degradation parameters; and

providing, to one or more computing devices, one or more degradation frames selected from the set of degradation frames in an order corresponding to the frame display order.

2. The computer-implemented method of claim 1, wherein the content includes image content.

3. The computer-implemented method of claim 1, wherein the content includes text content.

4. The computer-implemented method of claim 1, wherein the one or more degradation frames are further selected from the set of degradation frames based at least in part on one or more psychophysical properties of vision.

5. The computer-implemented method of claim 1, wherein the frame display order includes at least one of:

sequential order, random order, stochastic order, an order based on psychophysics, or an acyclic order.

6. The computer-implemented method of claim 1, further comprising:

selecting, from each degradation frame of the one or more degradation frames selected from the set of degradation frames, at least a art of the non-degraded content based at least in part on one or more properties associated with each degradation frame of the one or more degradation frames selected from the set of degradation frames;

adding the at least the part of the non-degraded content to a set of non-degraded content; and

creating a non-degraded image based at least in part on the set of non-degraded content.

7. A system, comprising:

at least one computing device configured to implement one or more services, wherein the one or more services are configured to;

generate a set of degradation frames that comprises multiple degradation frames, each degradation frame of the set of degradation frames based at least in part on a source frame, each degradation frame of the set of degradation frames generated from the source frame using a set of degradation parameters;

determine a frame display order; and

display at least a subset of the set of degradation frames in an order corresponding to the frame display order, the at least a subset of the set of degradation frames selected from the set of degradation frames based at least in part on a set of non-degraded content associated with the degradation frame.

8. The system of claim 7, wherein the set of degradation parameters is based at least in part on the source frame.

9. The system of claim 7, wherein the set of degradation parameters is based at least in part on one or more psychophysical properties of vision.

10. The system of claim 7, wherein the frame display order is acyclic.

11. The system of claim 7, wherein the set of degradation parameters at least comprises:

a first subset of degradation parameters configured to cause the one or more services to generate a first one of more portions of the degradation frame by copying data from one or more portions of the source frame corresponding to the first one or more portions of the degradation frame; and

a second subset of degradation parameters configured to cause the one or more services to generate a second one or more portions of the degradation frame by altering data from one or more portions of the source frame corresponding to the second one or more portions of the degradation frame.

12. The system of claim 7, wherein each frame of the set of degradation frames at least includes a subset of the source frame;

and a set of subsets of the source frame included in the set of degradation frames at least comprises the source frame.

13. The system of claim 7, wherein the set of non-degraded content associated with the degradation frame is generated from the source frame based at least in part on a randomly selected portion of the source frame.

14. A non-transitory computer-readable storage medium having code stored thereon that, when executed by a computer, causes the computer to perform operations including:

determine a set of degradation parameters based at least in part on a source frame;

generate a set of degradation frames that comprises multiple degradation frames, each degradation frame of the set of degradation frames at least comprising a set of non-degraded data based at least in part on the source frame, each degradation frame of the set of degradation frames at least comprising a set of degraded data based at least in part on the set of degradation parameters;

determine a frame display order based at least in part on the set of degradation parameters; and

provide one or more degradation frames selected from the set of degradation frames in an order corresponding to the frame display order, the one or more degradation frames selected from the set of degradation frames based at least in part on the set of non-degraded data.

15. The non-transitory computer-readable storage medium of claim 14,

wherein the set of degradation parameters is based at least in part on persistence of vision.

wherein the source frame includes one or more text elements.

17. The non-transitory computer-readable storage medium of claim 16,

wherein the first set of characters is selected randomly.

19. The non-transitory computer-readable storage medium of claim 16,
