Publication number: 20100259622Abstract: A method of automatically determining a need to service a digital image acquisition system including a digital camera with a lens assembly includes analyzing pixels within one or more acquired digital images according to probability determinations that such pixels correspond to blemish artifacts. It is automatically determined whether a threshold distribution of blemish artifacts is present within one or more of the digital images. A need for service is indicated when at least the threshold distribution is determined to be present.Type: ApplicationFiled: March 8, 2010Publication date: October 14, 2010Applicant: FotoNation Vision LimitedInventors: Eran Steinberg, Yury Prilutsky, Peter Corcoran, Petronel Bigioi, Adrian Zamfir, Vasile Buzuloiu, Danutz Ursu, Marta Zamfir

Patent number: 7545995Abstract: A method of automatically correcting dust artifact within images acquired by a system including a digital camera includes determining that certain pixels correspond to dust artifact regions within a first digitally-acquired image. The dust artifact regions are associated with one or more extracted parameters relating to a variable optical system of the digital camera when the first image was acquired. An associated statistical dust map is formed including mapped dust regions based on known correspondence between effects on dust artifact data of values of extracted parameters. Pixels corresponding to correlated dust artifact regions within a second image acquired with said digital camera are corrected according to one or more different values of the extracted parameters relating to the variable optical system based on the associated statistical dust map.Type: GrantFiled: February 25, 2008Date of Patent: June 9, 2009Assignee: FotoNation Vision LimitedInventors: Eran Steinberg, Yury Prilutsky, Peter Corcoran, Petronel Bigioi, Adrian Zamfir, Vasile Buzuloiu, Danutz Ursu, Marta Zamfir

Patent number: 7536060Abstract: A method automatically corrects dust artifact within images acquired by a system including a digital acquisition device including a lens assembly. Multiple original digital images are acquired with the digital acquisition device. Probabilities that certain pixels correspond to dust artifact regions within the images are determined based at least in part on a comparison of suspected dust artifact regions within two or more of the images. Probable dust artifact regions are associated with extracted parameter values relating to the lens assembly when the images were acquired. A statistical dust map is formed including mapped dust regions based on the determining and associating. Pixels corresponding to correlated dust artifact regions are corrected within further digitally-acquired images based on the associated statistical dust map.Type: GrantFiled: February 15, 2008Date of Patent: May 19, 2009Assignee: FotoNation Vision LimitedInventors: Eran Steinberg, Yury Prilutsky, Peter Corcoran, Petronel Bigioi, Adrian Zamfir, Vasile Buzuloiu, Danutz Ursu, Marta Zamfir
