Abstract

An image can be sensed at a first device. The image can have a first orientation. A second orientation expected by or associated with a second device can be determined. The image can be modified so that the image has the second orientation if the first orientation differs from the second orientation. The modified image can be transmitted to the second device.

Claims

1. A computing device comprising:

a camera to generate image data;

a communication interface configured to receive a display orientation from a second computing device; and

a controller to;

modify an image orientation of the image data to the display orientation received from the second computing device in response to a determination that the image orientation of the image data is different from the display orientation; and

transmit the modified image data to the second device.

2. The computing device of claim 1, wherein the image orientation is landscape and the display orientation is portrait.

3. The computing device of claim 1, wherein the controller is configured to determine the image orientation by applying object recognition techniques to determine an orientation of an object represented in the image data.

4. The computing device of claim 1, further comprising:

an accelerometer to determine an orientation of the computing device,

wherein the controller is configured to determine the image orientation of the image data using a value from the accelerometer.

5. The computing device of claim 1, wherein the computing device is a smart phone, a tablet computer, or a slate computer.

6. A method comprising:

sensing, by an image sensor of a first device, an image having a first orientation;

determining, by the first device, a second orientation expected by a second device in communication with the first device;

in response to a determination that the first orientation is different from the second orientation, modifying the image by the first device so that the image has the second orientation; and

transmitting the modified image from the first device to the second device.

7. The method of claim 6, wherein modifying the image so that the image has the second orientation comprises rotating the image.

8. The method of claim 7, wherein modifying the image so that the image has the second orientation further comprises at least one of scaling the image and cropping the image.

9. The method of claim 8,

wherein the image comprises a depiction of a face, and

wherein the at least one of scaling the image and cropping the image is performed such that the depiction of the face is retained in the modified image.

10. The method of claim 8, comprising:

setting the second orientation expected by the second device at a beginning of a communication session between the first device and the second device.

11. The method of claim 9, wherein the second orientation expected by the second device corresponds to an orientation of a display of the second device.

12. The method of claim 9, further comprising:

receiving an indication from the second device that the orientation of the display of the second device has changed to a different orientation; and

updating the second orientation expected by the second device to be the different orientation.

13. The method of claim 6, wherein the first device and the second device are in communication to establish a video call.

14. A non-transitory machine-readable storage medium comprising instructions, which when executed, cause a processor of a first communication device to:

generate an image using a sensor of the first communication device;

determine a first orientation of the image;

determine a second orientation associated with a second communication device;

in response to a determination that the first orientation and the second orientation are different, modify the image to the second orientation; and

transmit the modified image to the second communication device.

15. The machine-readable medium claim 14, further comprising instructions, which when executed, cause the processor to change the resolution of the modified image,

rotated image comprise at least one of scaling the rotated image and cropping the rotated image so that the rotated image has a resolution associated with the second orientation.

16. The machine-readable medium of claim 15, wherein the instructions, which when executed, cause the processor to change the resolution of the modified image comprise scaling the modified image based on a resolution associated with the second orientation.

17. The machine-readable medium of claim 15, wherein change the resolution of the modified image comprise cropping the modified image based on a resolution associated with the second orientation.

18. The machine-readable medium of claim 14, wherein modify the image to the second orientation comprise instructions to rotate the image.

19. The machine-readable medium of claim 14, further comprising instructions, which when executed, cause the processor to:

receive an indication from the second device that the orientation of the display of the second device has changed to a different orientation; and

update the second orientation expected by the second device to be the different orientation.

20. The machine-readable medium of claim 14, wherein the first communication device and the second communication device are to present a video call.
