    摘要: A method for reducing the row noise from complementary metal oxide semiconductor (CMOS) image sensor by using average values from sub-regions of the shielded pixels. The method operates on sensor with and without a Color Filter Array (CFA) before any interpolation is applied and estimates the local offset by subtracting out outliers and averaging the averages of sub-regions in the shielded pixels. The method also reduces the pixel-to-pixel noise while reducing the row noise.

    摘要: The present invention is directed at method of designing a Color Filter Arrays (CFA) for CMOS image sensors under the effects of crosstalk for optimal color reproduction. Instead of a focus on lowering crosstalk, a novel method of designing color filter spectral responses to compensate for the effect of crosstalk at the color imaging system level is proposed. As part of this method, a color reproduction model for CMOS and CCD image sensor under the effect of crosstalk is also proposed.

    摘要: A shallow water mooring system applies to offshore industry for oil and gas exploration, and production. This mooring system employs non-steel synthetic lines to provide the desired flexibility for shallow water mooring system applications. Piled submerged towers at seabed serve as elevated anchors to keep the whole synthetic mooring lines off the seabed under environmental loading conditions. Other buoyant means such as a buoy is also utilized to further help the synthetic mooring lines off the seabed during their service life.

    摘要: A scanner has a window in its housing through which the scanning beam emerges to impinge upon an indicia to be read. The beam scans in a raster fashion over the window, and as it does so it impinges upon beam position indicating means which locate the position of the beam with respect to the scanner in at least certain portions of the scan pattern. Specifically, the beam position indicating means determines the position of the beam in a direction perpendicular to the overall scanning direction. In a preferred embodiment, the beam position indicating means may comprise one or more CCD's which provide electrical output signals dependent upon the position of the beam when it impinges upon them. Alternatively, the beam position indicating means may comprise passive code means such as a stacked series of bar code symbols. The location of the beam when it scans across the symbol can be determined by the unique pattern of reflections.

    摘要: An image capture apparatus comprises an image sensor array including a plurality of image sensors arranged in a two-dimensional (2-D) array and an analog-to-digital converter (ADC) array including a plurality of ADCs arranged in a 2-D array. The image sensor array is divided into a plurality of sub-arrays, each of which includes at least two image sensors. The image sensor array is vertically stacked on the ADC array. Each ADC corresponds to one sub-array of image sensors and is coupled to process signals output by the image sensors in the corresponding sub-array.
