Abstract
Official abstract text for this publication.
In one application, an imaging device includes an image sensor having an array of pixels, and a mask coupled with the image sensor. The mask is configured to darken a plurality of isolated pixels or groups of pixels interspersed within the array of pixels. The imaging device also includes a processor coupled with the image sensor and configured to receive image data from the image sensor, and determine a dark current fixed pattern noise based on the image data received from the plurality of darkened pixels or groups of pixels.
First claim
Opening claim text (preview).
What is claimed is: 1. A mask coupled with an image sensor wherein the image sensor comprises an array of pixels and a fiber faceplate coupled to the array of pixels, the mask further configured to darken a plurality of isolated pixels or groups of pixels interspersed within the array of pixels, the mask disposed over the fiber faceplate. 2. The mask of claim 1 wherein the mask is configured to darken the plurality of isolated pixels or groups of pixels interspersed within the array of pixels in a random or semi-random distribution. 3. The mask of claim 1 wherein the mask is configured to darken the plurality of isolated pixels or groups of pixels interspersed within the array of pixels in a two dimensional array. 4. The mask of claim 1 wherein the mask is configured to darken a plurality of non-adjacent pixels in the array of pixels. 5. The mask of claim 1 wherein the mask is configured to darken a plurality of a group of more than one adjacent pixel in the array of pixels. 6. The mask of claim 1 wherein the mask comprises a thin sheet of transparent material attached to the fiber faceplate. 7. The mask of claim 1 wherein the mask comprises evaporated absorbing or reflecting material directly onto the fiber faceplate.
