Reducing noise in digital images

A target digital image is received from an image sensor. The image is contaminated by noise of unknown magnitude that is represented by a reference digital image. A process 5 is applied that uses statistical analysis of the target digital image and of the reference digital image to estimate a magnit...

Summary:A target digital image is received from an image sensor. The image is contaminated by noise of unknown magnitude that is represented by a reference digital image. A process 5 is applied that uses statistical analysis of the target digital image and of the reference digital image to estimate a magnitude of the noise for at least some pixels of the target digital image. 1292757 1 (GHMItters) P80185.AU.1 OPTICS CMVOS SENSOR ARRAY INPUT DIGITAL IMAGE (T) 10 22 NOISES-I -STO1RAGE, 38)REDUCTION .2 T, 10 SOFTWARE FUGPUT DIGITAL IMAGE, () QUANTITATIVE DETERMiNATIO.N, 30
