  • Patent number: 9215386
    Abstract: A pixel readout circuit for use with an imaging pixel array, comprising: an input channel for receiving an image signal corresponding to an electrical output of a photosensitive element of the pixel; and an electronic circuit interconnected between an input channel and an output readout utility. The electronic circuit comprises a capacitive unit, and a single analyzer. The capacitive unit is controllably linked to the input channel for accumulating a charge corresponding to received intensity generated by the pixel during a single frame period, and is connected to the output readout utility.
    Type: Grant

The electronic circuit comprises a capacitive unit, and a single analyzer. The capacitive unit is controllably linked to input channel for accumulating charge corresponding to received intensity generated by said pixel during a single frame period, and is connected to output readout utility. The signal analyzer unit is controllably linked to input channel and connected to output readout utility, and is configured for analyzing at least a part of said image signal by determining change in amount of accumulated charge corresponding to the received intensity, and upon detecting that the amount of charge satisfies a predetermined condition generating data indicative of a detected event.

  • Patent number: 7135680
    Abstract: A focal plane array detector in a sensor for IR imaging. Pixel readout and analog to digital conversion is performed in an integrated circuit which includes the imaging array. The charge of each pixel is accumulated in a capacitor (16) and a digital to analog charge converter cancels this charge. A controller controls this charge converter providing the appropriate amount of charge. An analog to digital converter incorporating a comparator (92) switches the controller on/off. In some embodiment a programmable device external to the sensor participates in the control of the analog to digital converter. In a typical embodiment of the invention a cycle generator controls the charge output of the digital to analog converter. In a preferred embodiment the analog to digital converters are grouped wherein all such converters group operate simultaneously.
