| 20100163972 | MULTI-DRAIN SEMICONDUCTOR POWER DEVICE AND EDGE-TERMINATION STRUCTURE THEREOF - An embodiment of a semiconductor power device provided with: a structural body made of semiconductor material with a first conductivity, having an active area housing one or more elementary electronic components and an edge area delimiting externally the active area; and charge-balance structures, constituted by regions doped with a second conductivity opposite to the first conductivity, extending through the structural body both in the active area and in the edge area in order to create a substantial charge balance. The charge-balance structures are columnar walls extending in strips parallel to one another, without any mutual intersections, in the active area and in the edge area. | 07-01-2010 |
| 20110049616 | SEMICONDUCTOR STRUCTURE FOR A POWER DEVICE AND CORRESPONDING MANUFACTURING PROCESS - An embodiment of a semiconductor structure for a power device integrated on a semiconductor substrate, of a first type of conductivity, and comprising:—an epitaxial layer, of said first type of conductivity, made on said semiconductor substrate, and having a plurality of column structures, of a second type of conductivity, to define a charge balancing region;—an active surface layer made on said epitaxial layer for housing a plurality of active regions; said epitaxial layer comprising a semiconductor separating layer arranged between the charge balancing region and the active surface layer, said semiconductor separating layer decoupling said column structures from said active regions. | 03-03-2011 |

| 20110052053 | DIGITAL IMAGE PROCESSING APPARATUS AND METHOD - An image processing apparatus suitable for processing a digital image in YCrCb color space, the image having an initial luminance plane Y and two initial Cr, Cb chrominance planes, the processing apparatus including a first block that receives the initial luminance plane Y of the digital image and processes and modifies the initial luminance plane Y in order to provide a modified luminance plane Y in output; a color artifact correction block, operating in parallel with the first block, the correction block receiving the initial planes Y, Cr, Cb of the image and modifying the initial chrominance planes Cr and Cb through a pixel by pixel processing approach with a mobile working window, the correction block having a false colors correction sub-block and a purple fringing correction sub-block, or both, the sub-blocks structured to modify values of the initial Cr, Cb chrominance planes based on information contained in the initial Cr, Cb chrominance planes and also based on information contained in the initial luminance plane Y. | 03-03-2011 |
| 20110158511 | METHOD AND APPARATUS FOR FILTERING RED AND/OR GOLDEN EYE ARTIFACTS - Processing method of a digital image to filter red and/or golden eye artifacts, the digital image comprising a plurality of pixel each comprising at least one digital value represented on a plurality of bits, the method comprising: a step of selecting at least one patch of pixels of the digital image comprising pixels potentially representative of a red and/or golden eye artifact; a step of classifying the at least one patch of pixels as “eye” or “non-eye”; a step of filtering said potentially representative pixels if said patch of pixels is classified as “eye”; wherein the classifying step comprises the operations of: converting the digital values of said patch of pixels into a Gray Code representation, overall obtaining a plurality of bit maps from said patch of pixels, each bit map being associated with a respective bit of said Gray Code; an operation of individually comparing said bit maps with corresponding bit map models belonging to a patch classifier produced by a statistical analysis of bit maps obtained by converting patches of pixels of digital images containing or not red and/or golden eye artifacts into said Gray Code representation. | 06-30-2011 |

| 20090010539 | Method and relative device of color interpolation of an image acquired by a digital color sensor - A method calculates statistical parameters in function of stochastic momentums of the pixel intensities of a same primary color or complementary hue of a first working window (2k+1)×(2k+1), and of at least a second working window of smaller size, both centered on the pixel to be filtered and in choosing, as a function of the values of these statistical parameters, for each pixel of the color image to be filtered, the most appropriate filtering algorithm for enhancing as much as possible the contour sharpness and reducing noise and artifacts. | 01-08-2009 |
| 20100097491 | Compound camera sensor and related method of processing digital images - In one embodiment, a light sensor includes four cell arrays, one for each color of the Bayer pattern, and four lenses each focusing the light coming from the scene to be captured on a respective cell array. The lenses are oriented such that at least a second green image, commonly provided by the fourth cell array, is both horizontally and vertically shifted (spaced) apart by half a pixel pitch from a first (reference) green image. In a second embodiment, the four lenses are oriented such that the red and blue images are respectively shifted (spaced) apart by half a pixel pitch from the first or reference green image, one horizontally and the other vertically, and the second green image is shifted (spaced) apart by half a pixel pitch from the reference green image both horizontally and vertically. | 04-22-2010 |
