Abstract
Systems and methods for identifying camera sensors are disclosed. In an exemplary implementation, a method for identifying camera sensors may include exposing a plurality of camera sensors at a time T1, each of the plurality of camera sensors having an array of pixels, and storing the location of unique pixels within the array of pixels for each of the camera sensors exposed at time T1 in a data structure. The method may also include exposing one of the plurality of camera sensors at time T2, and comparing the unique pixels within the array of pixels for the one camera sensor exposed at time T2 with locations of unique pixels of each of the camera sensors exposed at time T1. The one camera sensor may be identified based on the comparing step.
Claims21
A system for identifying camera sensors, comprising:
- a data structure including at least a first field for storing a pixel location, a second field for storing a plurality of camera sensor identifiers corresponding to the pixel location if a camera sensor is determined to have a unique pixel during at least one exposure of a plurality of camera sensors during exposure at a first time T1;
- and
- a comparison engine for comparing unique pixels from exposure of one of the plurality of camera sensors during at least one exposure at a second time T2, the comparison engine identifying the camera sensor from the camera sensor identifier corresponding to the most matching unique pixels during exposure at time T1 and time T2.
A method for identifying camera sensors comprising:
- exposing a plurality of camera sensors at a time T1, each of the plurality of camera sensors having an array of pixels;
- storing the location of unique pixels within the array of pixels for each of the camera sensors exposed at time T1 in a data structure;
- exposing one of the plurality of camera sensors at time T2;
- comparing the unique pixels within the array of pixels for the one camera sensor exposed at time T2 with locations of unique pixels of each of the camera sensors exposed at time T1;
- and
- identifying the one camera sensor based on the comparing step.
A system for identifying camera sensors, comprising:
- means for storing pixel data for a plurality of camera sensors during a manufacturing process;
- means for comparing pixel data for at least one of the plurality of camera sensors at a later time to the pixel data stored during the manufacturing process;
- and
- means for identifying the at least one camera sensor based on matching pixel data.
