Patent number: 8259189Abstract: An electronic camera includes an image sensor having a plurality of pixels and a control section that sets an imaging sensitivity at a time of imaging. Each of the pixels includes a first light receiving element that generates a first image signal, a second light receiving element that generates a second image signal higher in the sensitivity than the first image signal under a same condition, and an output circuit capable of adding the first image signal and the second image signal. The control section specifies an output signal of each of the pixels from the first image signal, the second image signal, and an additional image signal of the first image signal and the second image signal in accordance with an SN ratio at the imaging sensitivity.Type: GrantFiled: June 2, 2010Date of Patent: September 4, 2012Assignee: Nikon CorporationInventor: Sinsuke Sambongi
