1. A system to control a camera application executed on a device, the system comprising:
- two or more ambient light sensors arranged at respective surface locations of the device, each of the two or more ambient light sensors configured to measure light intensity of ambient light at the respective surface location; and
a processor configured to;
receive light intensity measurements of ambient light at each of the respective surface locations by the two or more ambient light sensors, wherein the light intensity measurements are obtained by the two or more ambient light sensors at a plurality of different time instants;
compare the light intensity measurements at each of the different time instants to detect movement information of an object in a view of a lens associated with the camera application; and
automatically adjust the camera application to account for the ambient light measured at each of the respective surface locations by the two or more ambient light sensors during image capture by a camera on the device,wherein the two or more ambient light sensors detect the light intensity using narrow viewing angles that define cylindrical-shaped zones of reception rather than cone-shaped zones of reception, the narrow viewing angles being configured such that the cylindrical-shaped zones of reception do not overlap.

Abstract
A system and method to control a camera application executed on a device are described. The system includes two or more ambient light sensors arranged at respective surface locations of the device, each of the two or more ambient light sensors measuring light intensity at the respective surface location. The system also includes a processor to determine an adjustment to the camera application based on information resulting from the light intensity measured at each of the respective surface locations.

12. A method of controlling a camera application executed on a device, the method comprising:
-
measuring, using two or more ambient light sensors arranged at respective surface locations of the device, the light intensity of ambient light at the respective surface locations at a plurality of different time instants; comparing the light intensity at each of the different time instants to detect movement information of an object in a view of a lens associated with the camera application using the light intensity of the ambient light; and using, during image capture by a camera on the device, a processor to automatically adjust the camera application to take into account the ambient light measurements at each of the respective surface locations by the two or more ambient light sensors, wherein the two or more ambient light sensors detect the light intensity using narrow viewing angles that define cylindrical-shaped zones of reception rather than cone-shaped zones of reception, the narrow viewing angles being configured such that the cylindrical-shaped zones of reception do not overlap. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
