  • Image differencing for analog photocell array
    Patent number: 6870150
    Abstract: Under an embodiment, a system includes an array of analog photocells; a first plurality of shift cells, each shift cell in the first plurality of shift cells being coupled to a corresponding analog photocell; and a second plurality of shift cells, each shift cell in the second plurality of shift cells being coupled to a corresponding shift cell in the first plurality of shift cells; and a differential operational amplifier having a first input coupled to a terminating output of the first plurality of shift cells and a second input coupled to a terminating output of the second plurality of shift cells.
    Type: Grant

  • IMAGE DIFFERENCING FOR ANALOG PHOTOCELL ARRAY
    Publication number: 20020033444
    Abstract: An apparatus comprising an analog photocell adapted to capture light energy incident upon it as an analog signal, a sample-and-hold amplifier coupled to the photocell and adapted to store the analog signal and a digital converter coupled to the amplifier, the converter transforming the analog signal into a digital value, the value proportional to the amount of the light energy.
