Abstract

A method includes capturing a first image associated with a portion of a display screen being shared. The method further includes rendering the first image in a preview window of the display screen being shared to form a second image. The second image is captured so as to determine whether the first image is duplicated in the second image. The duplication of the first image in the second image is masked to form a third image. The third image is rendered in the preview window.

First claim

What is claimed is:

1 . A computer-implemented method, comprising:
capturing a first image associated with a portion of a display screen being shared in an online environment; altering an aspect of the first image to form a second image; rendering the second image in a preview window of the display screen being shared, in the online environment, to form a third image; altering an aspect of the third image to form a fourth image; determining whether the fourth image comprises duplication of the second image; and responsive to determining that the fourth image comprises the duplication of the second image, masking the duplication of the second image in the fourth image.

2 . The computer-implemented method of claim 1 , wherein masking the duplication of the second image comprises superimposing a masking window.

3 . The computer-implemented method of claim 1 , wherein the first image is altered in response to capturing the first image.

4 . The computer-implemented method of claim 1 , wherein the second image comprises an updated window that displays the preview window.

5 . The computer-implemented method of claim 1 , wherein the altering the aspect of the third image is opposite but equal in value to the altering the aspect of the first image.

6 . The computer-implemented method of claim 1 , further comprising rendering the fifth image in the preview window to form a sixth image.

7 . The computer-implemented method of claim 1 , wherein the altering the aspects is undetectable by human eye.

8 . A non-transitory, computer-readable medium, storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
capturing a first image associated with a portion of a display screen being shared in an online environment; altering an aspect of the first image to form a second image; rendering the second image in a preview window of the display screen being shared, in the online environment, to form a third image; altering an aspect of the third image to form a fourth image; determining whether the fourth image comprises duplication of the second image; and responsive to determining that the fourth image comprises the duplication of the second image, masking the duplication of the second image in the fourth image.

9 . The non-transitory, computer-readable medium of claim 8 , wherein masking the duplication of the first image comprises superimposing a masking window.

10 . The non-transitory, computer-readable medium of claim 8 , wherein the first image is altered in response to capturing the first image.

11 . The non-transitory, computer-readable medium of claim 8 , wherein the second image comprises an updated window that displays the preview window.

12 . The non-transitory, computer-readable medium of claim 8 , wherein the altering the aspect of the third image is opposite but equal in value to the altering the aspect of the first image.

13 . The non-transitory, computer-readable medium of claim 8 , wherein the instructions further comprise rendering the fifth image in the preview window to form a sixth image.

14 . The non-transitory, computer-readable medium of claim 8 , wherein the altering the aspects is undetectable by human eye.

15 . A system, comprising:
one or more processors; a memory operatively connected to the one or more processors and storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
capturing a first image associated with a portion of a display screen being shared in an online environment;
altering an aspect of the first image to form a second image;
rendering the second image in a preview window of the display screen being shared, in the online environment, to form a third image;
altering an aspect of the third image to form a fourth image;
determining whether the fourth image comprises duplication of the second image; and
responsive to determining that the fourth image comprises the duplication of the second image, masking the duplication of the second image in the fourth image.

16 . The system of claim 15 , wherein masking the duplication of the first image comprises superimposing a masking window.

17 . The system of claim 15 , wherein the first image is altered in response to capturing the first image.

18 . The system of claim 15 , wherein the second image comprises an updated window that displays the preview window.

19 . The system of claim 15 , wherein the altering the aspect of the third image is opposite but equal in value to the altering the aspect of the first image.

20 . The system of claim 15 , wherein the instructions further comprise rendering the fifth image in the preview window to form a sixth image.
