Patent number: 8420996Abstract: An apparatus includes an array containing N sub-diffraction limit light sensors each having an associated light absorption activation threshold for switching from a reset state to an activated state, where the light absorption activation values lie within a range of values. The apparatus further includes a processor connected with a memory including computer program code, where the memory and computer program code are configured to, with the processor, cause the apparatus at least to perform estimating an intensity of light that illuminates the array based on electrical outputs of the array.Type: GrantFiled: December 23, 2009Date of Patent: April 16, 2013Assignee: Nokia CorporationInventors: Tero P.

Patent number: 8198578Abstract: An apparatus includes an array of sub-diffraction limit-sized light receptors formed in a substrate having a light receiving surface. Each light receptor may be configured to output a binary valued bit element and to change state between an off-state and an on-state by the absorption of at least one photon. The apparatus further includes an optical filter structure disposed over the light receiving surface, the optical filter structure having of an array of filter pixels each having an associated passband spectral characteristic. A data element obtained from the array of sub-diffraction limit-sized light receptors is composed of a plurality of the bit elements output from a plurality of light receptors that underlie filter pixels having at least two different passband spectral characteristics.Type: GrantFiled: June 23, 2009Date of Patent: June 12, 2012Assignee: Nokia CorporationInventors: Samu T. Koskinen, Ossi M. Kalevo, Tero Rissa, Juha H. Alakarhu

Patent number: 8179457Abstract: An apparatus includes an array of sub-diffraction limit-sized light receptors formed in a substrate having a light receiving surface. Each receptor is configured to output an n-bit element and to change state based on the absorption of at least one photon (n is an integer >0). The apparatus includes an optical filter structure disposed over the light receiving surface, the structure having an array of filter pixels, each having an associated passband spectral characteristic. A data element obtained from the array of receptors is generated from a combination of a plurality of the n-bit elements output from a plurality of light receptors that underlie filter pixels having at least two different passband spectral characteristics. The filter pixels having at least two different passband spectral characteristics form a gradient filter wherein bandpass regions increase when moving from a central region of the gradient filter towards an edge region.Type: GrantFiled: June 23, 2009Date of Patent: May 15, 2012Assignee: Nokia CorporationInventors: Samu T.

Publication number: 20100321511Abstract: At a digital imaging system, a first set of samples of a scene are digitally captured with a first array of image sensing nodes while simultaneously a second set of samples of the scene are digitally captured with a second array of image sensing nodes. Image sensing nodes of the second array are oriented in a rotated position relative to the image sensing nodes of the first array. The first and second sets of samples are integrated with one another while correcting for the rotated orientation of the image sensing nodes of the second array relative to the image sensing nodes of the first array, and from that integration is output a high resolution image. In specific embodiments, there may be additional arrays of image sensing nodes, different arrays may sample different size portions of the scene, and be also rotated relative to other sensing node arrays.Type: ApplicationFiled: June 18, 2009Publication date: December 23, 2010Inventors: Samu T.
