Patent ID: 8786708

Claim:
A method for characterizing image sensor pixels arranged in an array, comprising the steps of: (a) illuminating a first portion of the array formed of pixels associated with a color filter of a first color; (b) measuring a response by a central pixel of the first portion; (c) illuminating a second portion of the array formed of a central pixel associated with a color filter of a second color and of peripheral pixels associated with a color filter of the first color; (d) measuring responses by the central pixel and the peripheral pixels of the second portion; (e) comparing the response by the central pixel of the first portion of the array and the responses by the central pixel and the peripheral pixels of the second portion of said array; and (f) outputting data indicative of a characterization of crosstalk between the central pixel and at least one peripheral pixel of the second portion based at least in part on a result of step (e).
