Abstract

The various embodiments described herein include a method for zooming a remote video feed performed at a client device. The method includes: receiving a first video feed having a first field of view from a camera located remotely from the client device; displaying the first field of view; and detecting a user input to zoom in on a particular portion. The method further includes: in response to detecting the user input, performing a software zoom function at the client device to display a second field of view corresponding to the particular portion at a first resolution; sending a crop command to the camera; in response to sending the crop command, receiving a second video feed from the camera, the second video feed corresponding to a cropped version of the first video feed and having a second resolution that is higher than the first resolution; and displaying the second video feed.

First claim

What is claimed is:

1 . A method of zooming a remote video feed, the method comprising:
receiving a first video feed from a camera located remotely from a client device, the first video feed having a first field of view; displaying, on a display of the client device, the first video feed with the first field of view; detecting a first user input to zoom in on a particular portion of the first video feed, the particular portion based on the first user input; in response to detecting the first user input, performing a software zoom function at the client device to display a second field of view at a first resolution, the second field of view corresponding to the particular portion; sending a camera crop command to the camera to generate a cropped version of the first video feed at the camera, the cropped version of the first video feed corresponding to the second field of view; in response to sending the camera crop command, receiving a second video feed from the camera, the second video feed corresponding to the cropped version of the first video feed and having a second resolution that is higher than the first resolution; and displaying, on the display, the second video feed at the second resolution.

2 . The method of claim 1 , wherein the display is a touch-screen display, and wherein the first user input is a pinch-out gesture performed on the first video feed.

3 . The method of claim 1 , further comprising, prior to the sending, detecting a second user input selecting a video enhancement affordance, wherein the sending is performed in response to detecting the second user input.

4 . The method of claim 3 , further comprising, in response to detecting the second user input and prior to sending the command, displaying a warning message indicating that saved video footage will be limited to the respective portion.

5 . The method of claim 1 , further comprising, in response to detecting the first user input, displaying a perspective window indicating a location of the particular portion relative to the first video feed.

6 . The method of claim 1 , further comprising, after displaying the second video feed, providing an affordance for resetting the camera to display the first video feed.

7 . The method of claim 1 , wherein displaying the first video feed with the first field of view comprises displaying the first video feed with the first field of view in a video monitoring user interface.

8 . The method of claim 1 , further comprising, prior to sending the camera crop command:
determining a current zoom magnification of the software zoom function and coordinates of the particular portion of the first video feed; and generating the camera crop command based on the current zoom magnification and the coordinates of the particular portion of the first video feed.

9 . An electronic device, comprising:
a display; one or more processors; and memory storing one or more programs to be executed by the one or more processors, the one or more programs comprising instructions for:
receiving a first video feed from a camera located remotely from a client device, the first video feed having a first field of view;
displaying, on the display, the first video feed with the first field of view;
detecting a first user input to zoom in on a particular portion of the first video feed, the particular portion based on the first user input;
in response to detecting the first user input, performing a software zoom function at the electronic device to display a second field of view at a first resolution, the second field of view corresponding to the particular portion;
sending a camera crop command to the camera to generate a cropped version of the first video feed at the camera, the cropped version of the first video feed corresponding to the second field of view;
in response to sending the camera crop command, receiving a second video feed from the camera, the second video feed corresponding to the cropped version of the first video feed and having a second resolution that is higher than the first resolution; and
displaying, on the display, the second video feed at the second resolution.

10 . The electronic device of claim 9 , wherein the display is a touch-screen display, and wherein the first user input is a pinch-out gesture performed on the first video feed.

11 . The electronic device of claim 9 , wherein the one or more programs further comprise instructions for, prior to the sending, detecting a second user input selecting a video enhancement affordance, wherein the sending is performed in response to detecting the second user input.

12 . The electronic device of claim 11 , wherein the one or more programs further comprise instructions for, in response to detecting the second user input and prior to sending the command, displaying a warning message indicating that saved video footage will be limited to the particular portion.

13 . The electronic device of claim 9 , wherein the one or more programs further comprise instructions for, in response to detecting the first user input, displaying a perspective window indicating a location of the particular portion relative to the first video feed.

14 . The electronic device of claim 9 , wherein the one or more programs further comprise instructions for, after displaying the second video feed, providing an affordance for resetting the camera to display the first video feed.

15 . A non-transitory computer-readable storage medium storing one or more programs, the one or more programs comprising instructions, which, when executed by an electronic device with a display and one or more processors, cause the electronic device to perform operations comprising:
receiving a first video feed from a camera located remotely from a client device, the first video feed having a first field of view; displaying, on the display, the first video feed with the first field of view; detecting a first user input to zoom in on a particular portion of the first video feed, the particular portion based on the first user input; in response to detecting the first user input, performing a software zoom function at the electronic device to display a second field of view at a first resolution, the second field of view corresponding to the particular portion; sending a camera crop command to the camera to generate a cropped version of the first video feed at the camera, the cropped version of the first video feed corresponding to the second field of view; in response to sending the camera crop command, receiving a second video feed from the camera, the second video feed corresponding to the cropped version of the first video feed and having a second resolution that is higher than the first resolution; and displaying, on the display, the second video feed at the second resolution.

16 . The non-transitory computer-readable storage medium of claim 15 , wherein the display is a touch-screen display, and wherein the first user input is a pinch-out gesture performed on the first video feed.

17 . The non-transitory computer-readable storage medium of claim 15 , wherein the instructions cause the electronic device to perform operations further comprising, prior to the sending, detecting a second user input selecting a video enhancement affordance, wherein the sending is performed in response to detecting the second user input.

18 . The non-transitory computer-readable storage medium of claim 17 , wherein the instructions cause the electronic device to perform operations further comprising, in response to detectin
