    摘要: Differential non-linearity errors in an A/D converter are corrected by an analog system. The system produces different analog voltages which are used to correct the input voltage to the capacitor. The input voltage is changed by an amount which is effective to correct the CAV to be the same as it would have been if the DNL error had not occurred.

    摘要: A current mode device for an active pixel sensor includes a voltage to current converter which includes an operation that occurs inside a source follower. The device operates to draw no current while the current is incoming. The device uses two stages of double sampling—one before the current-mode op amp and one after.

    摘要: An image sensor operable to vary the output spatial resolution according to a received light level while maintaining a desired signal-to-noise ratio. Signals from neighboring pixels in a pixe patch with an adjustable size are added to increase both the image brightness and signal-to-noise ratio. One embodiment comprises a sensor array for receiving input signals, a frame memory array for temporarily storing a full frame, and an array of self-calibration column integrators for uniform column-parallel signal summation. The column integrators are capable of substantially canceling fixed pattern noise.

    摘要: The invention computes the optimum path across a terrain or topology represented by an array of parallel processor cells interconnected between neighboring cells by links extending along different directions to the neighboring cells. Such an array is preferably implemented as a high-speed integrated circuit. The computation of the optimum path is accomplished by, in each cell, receiving stimulus signals from neighboring cells along corresponding directions, determining and storing the identity of a direction along which the first stimulus signal is received, broadcasting a subsequent stimulus signal to the neighboring cells after a predetermined delay time, whereby stimulus signals propagate throughout the array from a starting one of the cells. After propagation of the stimulus signals throughout the array, a master processor traces back from a selected destination cell to the starting cell along an optimum path of the cells in accordance with the identity of the directions stored in each of the cells.

    摘要: A charge-coupled device (CCD) is formed by first defining relatively deep trenches having relatively small lateral dimensions in the surface of a silicon bulk region. A relatively thin silicon dioxide layer is formed over the silicon surface and inside each trench to cover the internal surfaces thereof. Finally, respective conducting electrode layers are formed over each trench covering the silicon dioxide layer within the trench. Such a CCD structure provides improved packing density and versatility of function over a conventional surface electrode CCD structures. When used in an image-sensing device, the trench-defined CCD structure provides improved quantum efficiency, owing to the deeper potential wells which may be formed in such structures for capturing photogenerated charge carriers.

    摘要: Multiple scans of a digital integration image sensor are combined to form an output image. The sensor scans or portions thereof may be positionally-shifted relative to one another, and may be acquired in uniform or non-uniform exposure intervals. Selected pixels within at least one of the scans may be excluded from the combination. The scans may also be non-uniformly weighted prior to being combined, with the scan weighting profile corresponding to the scan order.
