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 to receive display aspect ratio from a second computing device; and

a controller to;

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

transmit the modified image data to the second device.

2. The computing device of claim 1, wherein:

the communication interface is further to receive a display orientation from the second device; and

the controller is further to;

store the display orientation received from the second computing device in a memory of the first device as an expected orientation of the second device; and

generate the modified image data based on the stored expected orientation.

3. The computing device of claim 1, wherein the display aspect ratio is a ratio represented by a width of a display area of a display of the second computing device by a height of the display area when the display is oriented according to the display orientation.

4. The computing device of claim 1, wherein the controller is to modify the aspect ratio of the image data by cropping the image data.

5. The computing device of claim 1, wherein the controller is to transmit the modified image data during a video call with the second computing device.

6. A method comprising:

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

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

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

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

7. The method of claim 6, comprising:

storing a display orientation expected by the second device in a storage of the first device as an expected orientation of the second device; and

modifying, by the first device, the image based on the stored expected orientation.

8. The method of claim 7, further comprising:

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

updating, by the first device, the stored expected orientation to be the different orientation.

9. The method of claim 6, wherein modifying the image so that the has the second aspect ratio comprises cropping the image.

10. The method of claim 9, wherein modifying the image so that the image has the second aspect ratio further comprises scaling the image.

11. The method of claim 10,

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.

12. The method of claim 6, wherein the second aspect ratio is a ratio represented by a width of a display area of a display of the second computing device by a height of the display area when the display is oriented according to the display orientation.

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

14. An article comprising a non-transitory machine-readable storage medium storing instructions that upon execution cause a processor of a first communication device to:

receive a display aspect ratio from a second computing device;

generate image data using an image sensor;

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

transmit the modified image data to the second device.

15. The article of claim 14, further comprising instructions to:

store a display orientation expected by the second device in a storage of the first device as an expected orientation of the second device; and

modify the image based on the stored expected orientation.

16. The article of claim 15, further comprising instructions 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 stored expected orientation to be the different orientation.

17. The article of claim 14, further comprising instructions to crop the image based on the display aspect ratio.

18. The article of claim 14, further comprising instructions to scale the image based on the display aspect ratio.

19. The article of claim 14, wherein the display aspect ratio is a ratio represented by a width of a display area of a display of the second computing device by a height of the display area when the display is oriented according to the display orientation.

20. The article of claim 14, wherein the first communication device is to transmit the modified image data during a video call with the second communication device.
