Abstract

A computer system automatically corrects a view of an image capture device. A view of an image capture device is adjusted by applying one or more modifications selected from a group of: a zoom modification, a pan modification, and a tilt modification, wherein the view is displayed at a client device during a viewing session and the one or more modifications are indicated by the client device. One or more corrective operations are applied to the adjusted view based on user input, wherein the one or more corrective operations include a rotational operation to correct the adjusted view. Subsequent operations based on the one or more corrective operations are applied during a subsequent viewing session with corresponding view settings. Embodiments of the present invention further include a method and program product for automatically correcting a view of an image capture device in substantially the same manner described above.

First claim

The invention claimed is:

1. A computer-implemented method for automatically correcting a view of an image capture device, the computer-implemented method comprising:
adjusting a view of an image capture device by applying one or more modifications selected from a group of: a zoom modification, a pan modification, and a tilt modification, wherein the view is displayed at a client device during a viewing session and the one or more modifications are indicated by the client device;
applying one or more corrective operations to the adjusted view based on user input, wherein the one or more corrective operations include a rotational operation to correct the adjusted view; and
applying subsequent operations automatically based on the one or more corrective operations during a subsequent viewing session with corresponding view settings, wherein the subsequent operations repeat at least a portion of the one or more corrective operations.

2. The computer-implemented method of claim 1 , wherein the rotational operation corrects the view based on a tilt angle of the client device relative to a user's head.

3. The computer-implemented method of claim 2 , wherein the tilt angle is determined when the client device is stationary for a predetermined amount of time.

4. The computer-implemented method of claim 1 , wherein the one or more corrective operations further include one or more corrective operations selected from a group of: a contrast adjustment, a color adjustment, a deskewing operation, and a defishing operation.

5. The computer-implemented method of claim 1 , wherein the subsequent operations based on the one or more corrective operations are automatically performed when the subsequent viewing session surpasses a threshold of similarity to the adjusted view.

6. The computer-implemented method of claim 1 , wherein the subsequent operations based on the one or more corrective operations are scaled based on a difference between the adjusted view and a view of the image capture device during the subsequent viewing session.

7. The computer-implemented method of claim 1 , wherein the subsequent operations based on the one or more corrective operations are further based on corrective operations determined from a plurality of previous viewing sessions.

8. A computer system for automatically correcting a view of an image capture device, the computer system comprising:
one or more computer processors;
one or more computer readable storage media;
program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more computer processors, the program instructions comprising instructions to:
adjust a view of an image capture device by applying one or more modifications selected from a group of: a zoom modification, a pan modification, and a tilt modification, wherein the view is displayed at a client device during a viewing session and the one or more modifications are indicated by the client device;
apply one or more corrective operations to the adjusted view based on user input, wherein the one or more corrective operations include a rotational operation to correct the adjusted view; and
apply subsequent operations automatically based on the one or more corrective operations during a subsequent viewing session with corresponding view settings, wherein the subsequent operations repeat at least a portion of the one or more corrective operations.

9. The computer system of claim 8 , wherein the rotational operation corrects the view based on a tilt angle of the client device relative to a user's head.

10. The computer system of claim 9 , wherein the tilt angle is determined when the client device is stationary for a predetermined amount of time.

11. The computer system of claim 8 , wherein the one or more corrective operations further include one or more corrective operations selected from a group of: a contrast adjustment, a color adjustment, a deskewing operation, and a defishing operation.

12. The computer system of claim 8 , wherein the subsequent operations based on the one or more corrective operations are automatically performed when the subsequent viewing session surpasses a threshold of similarity to the adjusted view.

13. The computer system of claim 8 , wherein the subsequent operations based on the one or more corrective operations are scaled based on a difference between the adjusted view and a view of the image capture device during the subsequent viewing session.

14. The computer system of claim 8 , wherein the subsequent operations based on the one or more corrective operations are further based on corrective operations determined from a plurality of previous viewing sessions.

15. A computer program product for automatically correcting a view of a camera, the computer program product comprising one or more computer readable storage media collectively having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:
adjust a view of an image capture device by applying one or more modifications selected from a group of: a zoom modification, a pan modification, and a tilt modification, wherein the view is displayed at a client device during a viewing session and the one or more modifications are indicated by the client device;
apply one or more corrective operations to the adjusted view based on user input, wherein the one or more corrective operations include a rotational operation to correct the adjusted view; and
apply subsequent operations automatically based on the one or more corrective operations during a subsequent viewing session with corresponding view settings, wherein the subsequent operations repeat at least a portion of the one or more corrective operations.

16. The computer program product of claim 15 , wherein the rotational operation corrects the view based on a tilt angle of the client device relative to a user's head.

17. The computer program product of claim 16 , wherein the tilt angle is determined when the client device is stationary for a predetermined amount of time.

18. The computer program product of claim 15 , wherein the one or more corrective operations further include one or more corrective operations selected from a group of: a contrast adjustment, a color adjustment, a deskewing operation, and a defishing operation.

19. The computer program product of claim 15 , wherein the subsequent operations based on the one or more corrective operations are automatically performed when the subsequent viewing session surpasses a threshold of similarity to the adjusted view.

20. The computer program product of claim 15 , wherein the subsequent operations based on the one or more corrective operations are scaled based on a difference between the adjusted view and a view of the image capture device during the subsequent viewing session.
