determining that the second application has priority over the first application to control the first camera; and

based on the second application having priority over the first application to control the first camera, denying the first application control of the first camera and granting the second application control of the first camera.

8 . The method of claim 7 , wherein the determination that the second application has priority to control the first camera over the first application is based on a priority table.

9 . The method of claim 7 , wherein the determination that the second application has priority to control the first camera over the first application is based on a query provided to a user.

10 . The method of claim 7 , further comprising granting the first application control of another camera of the plurality of cameras.

11 . A method for managing control of cameras, the method comprising:

granting a first application running on a device control of a first camera of a plurality of cameras of the device;

controlling the first camera based on one or more settings;

responsive to a request from the first application to control a second camera of the plurality of cameras, granting the first application control of the second camera;

controlling the second camera based on the one or more settings;

receiving a request from a second application running on the device to control one or more cameras of the plurality of cameras; and

granting the second application control of one or more unused active cameras of the plurality of cameras while the first application maintains control of the first camera.

12 . The method of claim 11 , wherein the method is performed by an application programming interface (API) that manages control of the plurality of cameras of the device.

13 . The method of claim 11 , wherein the one or more settings are related to at least one of:

ISO value;

exposure time;

aperture size;

lens defocus value;

exposure gain;

focus window;

color temperature;

color channel gains;

automatic exposure control (AEC);

automatic white balance (AWB); or

automatic focus (AF).

14 . The method of claim 11 , wherein the one or more settings comprise one or more first settings, wherein the method further comprises:

receiving data output by two or more cameras of a plurality of cameras of a device; and

determining one or second more settings for operation of the plurality of cameras based on the data.

15 . The method of claim 11 , wherein granting the first application control of the first camera comprises granting the first application control over image- capture settings of the first camera and wherein granting the second application control of the one or more unused active cameras comprises granting the second application control over image- capture settings of the one or more unused active cameras.

16 . The method of claim 11 , further comprising:

receiving a request from a third application to control one or more cameras of the plurality of cameras; and

granting the third application control of one or more unused active cameras of the plurality of cameras.

17 . The method of claim 11 , further comprising:

determining that the second application has priority to control the first camera over the first application;

denying the first application control of the first camera; and

granting the second application control of the first camera.

18 . The method of claim 17 , wherein the determination that the second application has priority to control the first camera over the first application is based on a priority table.

19 . The method of claim 17 , wherein the determination that the second application has priority to control the first camera over the first application is based on a query provide to a user.

20 . The method of claim 11 , further comprising granting the first application control of another camera of the plurality of cameras.
