Abstract

Claims (38)

1. An information handling system for providing computer implemented services to users, comprising:

a camera;

a low power manager that manages operation of the camera;

a storage for storing:

context data regarding an operating state of the information handling system, and management policies for managing operation of the camera; and

a camera settings manager that dynamically updates operation of the low power manager using the context data and the management policies, wherein the camera settings manager is programmed to:

obtain the context data, wherein the context data specifies that the information handling system is in a presentation mode of operation;

obtain the management policies;

generate a low power manager update using the context data and the management policies, wherein the low power manager update specifies that an amount of time in which a user is detected using the camera is increased; and

update the operation of a low power manager using the low power manager update.

2. The information handling system of claim 1 , further comprising:

a system manager that manages a power state of the information handling system.

3. The information handling system of claim 2 , wherein the system manager disables operation of the camera settings manager when the information handling system is in a low power state and enables the operation of the camera settings manager when the information handling system is in a nominal power state.

4. The information handling system of claim 3 , wherein the low power manager continues to operate regardless of the power state of the information handling system.

5. The information handling system of claim 1 , wherein the low power manager is adapted to:

obtain image data using the camera;

identify an alert using the image data; and

modify a power state of the information handling system based on the alert.

6. The information handling system of claim 1 , wherein the low power manager manages the operation of the camera by modifying firmware that defines the operation of the camera based on camera management data maintained by the low power manager.

7. The information handling system of claim 6 , wherein dynamically updating the operation of the low power manager dynamically modifies the camera management data in response to changes in the context data.

8. The information handling system of claim 1 , wherein the low power manager is a system on a chip comprising a processor executing code which provides the camera controller.

9. A method for managing operation of a camera of an information handling system using context data and management policies, comprising:

obtaining, by a camera settings manager executing on a processor subject to suspension of operation based on a power state of the information handling system, the context data, wherein the context data specifies that the information handling system is in a presentation mode of operation;

obtaining, by the camera settings manager, the management policies;

generating, by the camera settings manager, a low power manager update using the context data and the management policies, wherein the low power manager update specifies that an amount of time in which a user is detected using the camera is increased; and

updating, by the camera settings manager, operation of a low power manager of the information handling system using the low power manager update.

10. The method of claim 9 , wherein updating the low power manager causes the low power manager to modify firmware of a camera of the information handling system.

11. The method of claim 9 , wherein the low power manager operates regardless of the power state of the information handling system.

12. The method of claim 9 , wherein the low power manager is a companion chip.

13. The method of claim 12 , wherein the companion chip continues to operate during a low power state of the information handling system that suspends execution of entities using one or more processors of the information handling system.

14. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for managing operation of a camera of an information handling system using context data and management policies, the method comprising:

obtaining, by a camera settings manager executing on a processor subject to suspension of operation based on a power state of the information handling system, the context data, wherein the context data specifies that the information handling system is in a presentation mode of operation;

obtaining, by the camera settings manager, the management policies;

generating, by the camera settings manager, a low power manager update using the context data and the management policies, wherein the low power manager update specifies that an amount of time in which a user is detected using the camera is increased; and

updating, by the camera settings manager, operation of a low power manager of the information handling system using the low power manager update.

15. The non-transitory computer readable medium of claim 14 , wherein updating the low power manager causes the low power manager to modify firmware of a camera of the information handling system.

16. The non-transitory computer readable medium of claim 14 , wherein the low power manager operates regardless of the power state of the information handling system.

17. The non-transitory computer readable medium of claim 14 , wherein the low power manager is a companion chip.
