    摘要： An imaging system for identifying the location of the center of mass (“COM”) in an image. In one aspect, an imaging system includes a plurality of photosensitive elements arranged in a matrix. A center of mass circuit coupled to the photosensitive elements includes a resistive network and a normalization circuit including at least one bipolar transistor. The center of mass circuit identifies a center of mass location in the matrix and includes: a row circuit, where the row circuit identifies a center of mass row value in each row of the matrix and identifies a row intensity for each row; a horizontal circuit, where the horizontal circuit identifies a center of mass horizontal value; and a vertical circuit, where the vertical circuit identifies a center of mass vertical value. The horizontal and vertical center of mass values indicate the coordinates of the center of mass location for the image.

    摘要： A cascaded imaging storage system for a pixel is disclosed for improving intrascene dynamic range. Charges accumulated in a first capacitor spill over into a second capacitor when a charge storage capacity of the first capacitor is exceeded. A third capacitor may also be provided such that charges accumulated by said second capacitor spill over into the third capacitor when the charge storage capacity of the second capacitor is exceeded.

    摘要： An image sensor is formed with shifts among the optical parts of the sensor and the photosensitive parts of the sensor. The optical parts of the sensor may include a color filter array and/or microlenses. The photosensitive part may include any photoreceptors such as a CMOS image sensor. The shifts allow images to be formed even when the light received at a given pixel location varies in angle of incidence as a function of pixel location within the array. The relative shifts among the pixel components may be, for example, plus or minus some fraction of the pixel pitch. The shift may be variable across the array or may be constant across the array and may be deterministically determined.

    摘要： A circuit and method for reducing kTC noise in CMOS imagers while minimizing power dissipation is disclosed. Correlated double sampling (CDS) is performed within each pixel such that the reset voltage and the integration voltage are sampled and stored within the pixel until the voltages are forwarded to a differential amplifier for subtraction.
