  • Patent number: 9961238
    Abstract: A gamut size metric is used in all phases of color image processing (e.g., capture, transmission, and display). In general, the gamut size metric is a single-valued metric that changes as image content changes. More particularly, a gamut boundary histogram is determined and used to estimate a gamut size metric. A gamut size metric identifies a minimum size gamut needed to encompass each pixel in an image, where the gamut size is limited at one end by a first device independent gamut (S1), and at another end by a second device independent color space (S2), where S1 is wholly enclosed within S2. The gamut size metric may be based on strict pixel color value differences. In other embodiments the gamut size metric may take into effect perceptual color differences and significance.

  • Patent number: 9950434
    Abstract: System and method for improving the shaving experience by providing improved visibility of the skin shaving area. A digital camera is integrated with the electric shaver for close image capturing of shaving area, and displaying it on a display unit. The display unit can be integral part of the electric shaver casing, or housed in a separated device which receives the image via a communication channel. The communication channel can be wireless (using radio, audio or light) or wired, such as dedicated cabling or using powerline communication. A light source is used to better illuminate the shaving area. Video compression and digital image processing techniques are used for providing for improved shaving results. The wired communication medium can simultaneously be used also for carrying power from the electric shaver assembly to the display unit, or from the display unit to the electric shaver.

  • Patent number: 9916645
    Abstract: A chroma subsampling having reduced artifacts is achieved by detecting high contrast areas in a luminance channel of an image to be chroma subsampled so as to partition the image into a first region composed of the high contrast areas and a second region distinct from the first region, with chroma subsampling the image in the first region using a first chroma subsampler and chroma subsampling the image in the second region using a second chroma subsampler, with the first chroma subsampler having a higher edge preserving property than compared to the second chroma subsampler. Thereby, bleeding artifacts may be avoided at least partially, while the saturation of the image may be substantially preserved.

  • Patent number: 9900485
    Abstract: An image generation device includes: a projector for projecting pattern light of a near-infrared wavelength at intervals; an imager for outputting an imaging signal of an imaged image; a unit for generating a pattern light image by obtaining a difference between the imaging signal when the pattern light is projected and the imaging signal when the pattern light is not projected, and generating an ambient light image from the imaging signal when the pattern light is not projected; a determiner for determining a type of the ambient light; and a generator for estimating, from the type, a component due to light of a near-infrared wavelength in the ambient light image, and generating a visible light image by subtracting the component from the ambient light image. The determiner determines the type from a proportion of R, G, and B components in the imaged image, ambient light image, or visible light image.

  • Patent number: 9870667
    Abstract: A system, method and computer program for tabulating votes and creating an audit trail is provided. A ballot processing device may include a paper feed mechanism, a computer, a ballot processing application loaded on the computer, and a digital scanning device linked to the computer. The ballot processing application may process the digital image to establish a series of processing results defining one or more voting results for the paper ballot, and also an audit trail. The ballot processing application may process the digital image to define the voting results based on criteria established by election officials, including ambiguous mark criteria. The audit trail enables election officials to verify that particular paper ballots have been processed correctly in accordance with these criteria.
