Abstract

Example refrigerators having internal content cameras, and methods of operating the same are disclosed. A disclosed example refrigerator includes a cabinet, an internal compartment disposed within the cabinet, a closing member operatively coupled to the cabinet providing selective access to the internal compartment, two cameras disposed in the compartment and positioned to capture images of different portions of the compartment, two light sources disposed in the compartment, and a controller communicatively coupled with the cameras and light sources and configured to control the light sources to provide two different illuminations for respective ones of the two cameras.

First claim

What is claimed is:

1 . A method of capturing images within an appliance, comprising:
coupling one or more doors to a cabinet to allow selective access to an internal compartment; coupling at least one camera and at least one light to said appliance to view the internal compartment; sensing a door closure event; sending a start notice from a controller of said appliance to an external server indicating that a new group of images of the internal compartment are being obtained; capturing a first image of a first portion of the internal compartment; capturing a second image of a second portion of the internal compartment; and sending an end notice to the external server to indicate the new group of images is complete.

2 . The method of claim 1 , further comprising:
setting the at least one light to a first illumination before the first image is captured; and setting the at least one light to a second illumination before the second image is capture.

3 . The method of claim 1 , further comprising:
setting the at least one light to a first color before the first image is captured; and setting the at least one light to a second color before the second image is capture.

4 . The method of claim 1 , further comprising:
adjusting a position of the at least one camera to a first angle to capture the first portion of the internal compartment in the first image; and adjusting the position of the at least one camera to a second angle to capture the second portion of the internal compartment in the second image.

5 . The method of claim 1 , further comprising:
sending the first image to the external server after the first image has been captured and before the second image has been captured; and sending the second image to the external server after the second image has been captured and before the end notice has been sent.

6 . The method of claim 1 , further comprising:
storing the first and second images locally in the controller until the new group of images is complete; and sending the first and second images to the external server when the new group of images is complete.

7 . A method capturing and storing images of contents of a refrigerator, comprising:
receiving a start notice from a controller of said refrigerator at an external server; initializing a record for a new group of images in the external server; receiving a first image of a first portion of an internal compartment of said refrigerator; storing the first image in the record of the external server; receiving a second image of a second portion of the internal compartment; storing the second image in the record in the external server; receiving an end notice from the controller; closing the record; and sending a notice to a user device when the first and second images are stored in the external server.

8 . The method of claim 7 , further comprising:
receiving a third image of a third portion of the internal compartment after storing the second image and before receiving the end notice; and storing the third image in the record.

9 . The method of claim 7 , further comprising:
coupling cameras to said refrigerator; and positioning the cameras at different angles to view different portions within the internal compartment, the different portions including the first portion and the second portion.

10 . The method of claim 9 , further comprising:
coupling lights to said refrigerator to provide for different illuminations of the internal compartment during capture of the first and second images.

11 . The method of claim 10 , further comprising:
adjusting the illuminations generated by the lights via a pulse-width modulator.

12 . The method of claim 10 , further comprising:
adjusting the lights via the controller between different angles.

13 . The method of claim 10 , further comprising:
sealing the cameras and the lights to reduce exposure to liquid.

14 . A method of imaging an internal compartment of an appliance, comprising:
coupling at least one camera and at least one light to an internal compartment of a cabinet of said appliance containing a door; initiating a starting event; adjusting the at least one camera to a first position; adjusting the at least one light to a first intensity; capturing a first image of the internal compartment of the cabinet with the at least one camera; adjusting the at least one camera to a second position; adjusting the at least one light to a second intensity; and capturing a second image of the internal compartment of cabinet with at least one camera, the second image being different than the first image.

15 . The method of claim 14 , further comprising:
adjusting the at least one camera to a first angle before capturing the first image; and adjusting the at least one camera to a second angle before capturing the second image.

16 . The method of claim 14 , wherein the step of initiating the starting event includes at least one of moving the door to a closed position and receiving a request from a user.

17 . The method of claim 14 , further comprising:
sending a notice to a server that the cabinet is to be imaged; establishing a record for the first and second images in the server; and storing the first and second images in the record in the server.

18 . The method of claim 17 , further comprising:
marking the first and second images in the record to indicate a portion of the cabinet that was captured; recording the record as a current image record; communicating an alert to a user device that the current image record has been stored on the server; and permitting access the record after the first and second images have been stored on the server.

19 . The method of claim 14 , wherein the step of coupling the at least one camera includes:
coupling the at least one camera to at least one of a liner of the door and a bottom of a storage bin coupled to the door.

20 . The method of claim 19 , wherein the step for coupling the camera to the liner of the door includes:
spacing the camera from contents in the internal compartment of cabinet to allow for a wider view of the contents.
