Abstract
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.
Claims7
A mask configured to be coupled with an image sensor wherein the image sensor comprises an 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 also configured to darken a continuous frame of pixels at a circumference of the image sensor.
