Publication number: 20130188045Abstract: The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for security cameras/systems with wide angle lenses, high resolution image sensors and intelligent control, image processing and image/video storage. After capturing a high resolution image of the large area, downscaling and subsequent storage of the captured image is performed based on the determined importance levels of regions throughout the captured high resolution image.Type: ApplicationFiled: January 20, 2012Publication date: July 25, 2013Inventor: Ossi M. Kalevo

Patent number: 8446484Abstract: Disclosed is an image signal processing chain or functionality having an image data scaler. A method includes receiving a stream of image data having a first resolution; scaling the received stream of image data using a substantially freely configurable downscaling ratio to generate scaled image data having a second resolution that is less than the first resolution; outputting the scaled image data to at least one of a viewfinder image signal processing functionality or a video image signal processing functionality to create image data for at least one of display to a user or provide to a video encoder; and during at least one of receiving, scaling or outputting, simultaneously storing the stream or a subset of the stream of image data having the first resolution into a memory as a set of frames of image data for being processed as needed.Type: GrantFiled: April 21, 2010Date of Patent: May 21, 2013Assignee: Nokia CorporationInventors: Mikko J. Muukki, Ossi M. Kalevo, Juha Sarkijarvi

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. Koskinen, Ossi M. Kalevo, Tero Rissa, Juha H. Alakarhu
