Abstract

A camera selection system and method for automatically selecting an appropriate camera to use for capturing photos and videos is provided. The method includes the steps of detecting that a camera application has been opened, activating a first camera and a second camera of the mobile device, analyzing a feed received from the first camera and a feed received from the second camera to detect whether a face is present in a field of view of the first camera or the second camera, determining that the user intends to use the first camera based on a detection of the face in the field of view of the first camera, deactivating the second camera in response to the determining and displaying the feed received from the first camera on the main display of the mobile device for viewing by the user while using the camera application.

First claim

What is claimed is:

1. A method for automatically selecting an appropriate camera to use for capturing photos and videos, the method comprising:
detecting, by a processor of a computing system, that a camera application loaded on the computing system has been opened by a user;
activating, by the processor, a first camera located on a first side of a mobile device and a second camera located on a second side of the mobile device in response to the detecting, the first camera facing the user and being located on a same side as a main display of the mobile device;
analyzing, by the processor, a feed received from the first camera and a feed received from the second camera to detect whether a face is present in a field of view of the first camera or the second camera;
first determining, by the processor, that the user intends to use the first camera if the face present in the field of view of the first camera that is at a position below the first camera or at an angled orientation to the first camera, and an identity of the user is confirmed, wherein in response to the first determining:
deactivating, by the processor; the second camera in response to the first determining, and
displaying, by the processor, the feed received from the first camera on the main display of the mobile device for viewing by the user while using the camera application;

second determining, by the processor, that another user other than the user is operating the camera application to take a standard photograph of the user if the identity of the user is not confirmed when the face is present n the field of view of the first camera, wherein in response to the second determining:
deactivating, by the processor, the second camera in response to the second determining, and
displaying, by the processor, the feed received from the first camera on the main display of the mobile device for viewing by the another user while using the camera application.

2. The method of claim 1 , wherein the identity of the user is confirmed by identifying, by the processor, the face as that of the user, using facial recognition software loaded on the computing system.

3. The method of claim 1 , further comprising: prior to deactivating and displaying as part of the first determining, confirming, by the processor, that the user intends to use the first camera by detecting an object placed over or partially over the second camera.

4. The method of claim 3 , wherein the object is a hand, a finger, or thumb of the user as the user holds the mobile device while using the camera application.

5. The method of claim 1 , wherein the second camera is a selected as a default if the face is not detected in the field of view of the first camera.

6. The method of claim 1 , wherein the detection of the face in the field of view of the first camera requires the face to be within a predetermined proximity to the first camera.

7. The method of claim 1 , wherein the analyzing of the feed received from the first camera is performed prior to the analyzing of the feed received from the second camera, to detect whether the face is present in the field of view of the first camera.

8. A computer system, comprising:
a processor;
a memory device coupled to the processor; and
a computer readable storage device coupled to the processor, wherein the story device contains program code executable by the processor via the memory device to implement a method for automatically selecting an appropriate camera to use for capturing photos and videos, the method comprising:
detecting, by a processor of a computing system, that a camera application loaded on the computing system has been opened by a user;
activating, by the processor, a first camera located on a first side of a mobile device and a second camera located on a second side of the mobile device in response to the detecting, the first camera facing the user and being located on a same side as a main display of the mobile device;
analyzing, by the processor; a feed received from the first camera and a feed received from the second camera to detect whether a face is present in a field of view of the first camera or the second camera;
first determining, by the processor, that the user intends to use the first camera if the face present in the field of view of the first camera that is at a position below the first camera or at an angled orientation to the first camera, and an identity of the user is confirmed, wherein in response to the first determining:
deactivating, by the processor, the second camera in response to the first determining, and
displaying, by the processor, the feed received from the first camera on the main display of the mobile device for viewing by the user while using the camera application;

second determining, by the processor, that another user other than the user is operating the camera application to take a standard photograph of the user if the identity of the user is not confirmed when the face is present in the field of view of the first camera, wherein in response to the second determining:
deactivating, by the processor, the second camera in response to the second determining, and
displaying, by the processor, the feed received from the first camera on the main display of the mobile device for viewing by the another user while using the camera application.

9. The computing system of claim 8 , wherein the identity of the user is confirmed by identifying, by the processor, the face as that of the user, using facial recognition software loaded on the computing system.

10. The computing system of claim 8 , further comprising: prior to deactivating and displaying as part of the first determining, confirming, by the processor, that the user intends to use the first camera by detecting an object placed over or partially over the second camera.

11. The computer system of claim 8 , wherein the detection of the face in the field of view of the first camera requires the face to be within a predetermined proximity to the first camera.

12. The computer system of claim 8 , wherein the analyzing of the feed received from the first camera is performed prior to the analyzing of the feed received from the second camera, to detect whether the face is present in the field of view of the first camera.

13. A computer program product, comprising a computer readable hardware storage device storing a computer readable program code, the computer readable program code comprising an algorithm that when executed by a computer processor of a computing system implements a method for automatically selecting an appropriate camera to use for capturing photos and videos, comprising:
detecting, by a processor of a computing system, that a camera application loaded on the computing system has been opened by a user;
activating, by the processor, a first camera located on a first side of a mobile device and a second camera located on a second side of the mobile device in response to the detecting, the first camera facing the user and being located on a same side as a main display of the mobile device;
analyzing, by the processor, a feed received from the first camera and a feed received from the second camera to detect whether a face is present in a field of view of the first camera or the second camera;
first determining, by the processor, that the user intends to use the first camera if the face present in the field of view of the first camera that is at a position below the first camera or at an angled orientation to the first camera, and an identity of the user is confirmed, wherein in response to the first determining:
deactivating, by the processor, the second camera in re
