Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A method, comprising:
capturing, using an optical sensor comprising first and second sensing matrices, an image of a scene;
analyzing a first pixel of the image to detect imbalanced pixel sensing values from the first and second sensing matrices;
analyzing a second pixel of the image to detect balanced pixel sensing values from the first and second sensing matrices;
comparing the imbalanced pixel sensing values and the balanced pixel sensing values to generate a result;
determining, based on the result, that a first portion of the scene associated with the first pixel corresponds to a background of the scene, and that a second portion of the scene associated with the second pixel corresponds to a pre-determined light source;
capturing, using a camera device comprising the optical sensor, a sequence of images comprising the image;
detecting, based on a pattern of local light change across the sequence of images, the pre-determined light source in the scene;
comparing, in response to detecting the pre-determined light source, a location of the pre-determined light source in at least one image of the sequence of images and a target position within the at least one image to generate a result; and
generating, based on the result, a control signal for changing a field-of-view of the camera device such that the pre-determined light source substantially aligns with the target position within the field-of-view.
