    摘要: A photo-sensor image resolution adjustment apparatus is in communication with an array of image photo-sensors that are organized in columns and rows and have multiple sensor types arranged in a pattern such as a Bayer pattern to detect light. The photo-sensor image resolution adjustment apparatus has a photo-sensor array decimation circuit to partition the array of image photo-sensors into a plurality of sub-groups. A column averaging circuit averages the light conversion electrical signals from common color photo-sensors within the sub-groups. A row averaging circuit averages the common color adjacent light conversion electrical signals from color adjacent rows within the sub-groups in high light intensity condition. In low light conditions, a row binning circuit integrates the common color adjacent light conversion electrical signals from color adjacent rows within the sub-groups.

    摘要: A circuit and method for correcting for power supply voltage noise using two dummy pixels in each row of pixels of an imager having a number of pixels arranged in rows and columns are described. The dummy pixels are driven by the same power supply as the active pixels but do not have the capability to sense light energy. The first dummy pixel is read at the time the active pixels in a row are reset and stores a signal in a first dummy register related to the voltage level of the power supply at the time the active pixels are reset. The second dummy pixel is read at the time the active pixels in the row are read and stores a signal in a second dummy register related to the voltage level of the power supply at the time the active pixels are read. The signals in the first storage register and second storage register can then be used to correct the signals from the active pixels in the row for the effect of noise caused by power supply voltage level fluctuations.

    摘要: An active pixel sensor circuit comprising a photodiode, a storage node, and a transfer gate between the photodiode and storage node, where the potential barrier between the photodiode and the storage region is maintained during charge accumulation, thereby preventing charge tunneling between the photodiode and the storage region. This is achieved by electrically connecting the transfer gate, which controls charge transfer between the photodiode and the storage region, to the storage region. Connecting the transfer gate to the storage region maintains the potential barrier between the photodiode and the storage region at a threshold voltage during the charge integration period which prevents charge tunneling between the photodiode and the storage node. The threshold voltage is determined by the implant levels used to form the active pixel sensor and can be optimized by using optimum implant levels. This prevention of charge tunneling between the photodiode and the storage node eliminates image lag.

    摘要: A method and apparatus for resolving relative times-of-arrival of a plurality of light pulses includes a plurality of drift-field detectors. Each drift-field detector includes a light sensor and a semiconductor drift region. Each light sensor generates an electrical charge from at least one of the plurality of light pulses. Each semiconductor drift region receives the electrical charge from its respective light sensor and, pursuant to an electric field therein, produces a spatial charge distribution. The spatial charge distribution for each of the semiconductor drift regions is stored in an analog storage device associated therewith. The relative positions of the charge distributions in the semiconductor drift regions are used to calculate the relative times-of-arrival of the light pulses.

    摘要: A DC-DC switching converter with an LC output filter has a switched capacitor converter providing the capacitance of the output filter. The switched capacitor converter may be a multi-phase switched capacitor converter. Topology of connections between capacitors of the multi-phase switched capacitor converter may be dependent on phases of clock signal(s) provided to the multi-phase switched capacitor converter. The switched capacitor converter may rely on parasitic inductances, or include discrete inductors, in series between connected capacitors to allow for adiabatic or near adiabatic voltage conversion.

    摘要: A digital color imager providing an extended luminance range, an improved color implementation and enabling a method for an easy transformation into another color space having luminance as a component has been achieved. Key of the invention is the addition of white pixels to red, green and blue pixels. These white pixels have either an extended dynamic rang as described by U.S. patent (U.S. Pat. No. 6,441,852 to Levine et al.) or have a larger size than the red, green, or blue pixels used. The output of said white pixels can be directly used for the luminance values Y of the destination color space. Therefore only the color values and have to be calculated from the RGB values, leading to an easier and faster calculation. As an example chosen by the inventor the conversion to YCbCr color space has been shown in detail.
