A detector pixel signal readout circuit and an imaging method thereof |
摘要 |
A pixel readout circuit for use with an imaging pixel array, said pixel readout circuit comprising: an input channel for receiving an image signal corresponding to electrical output of a photosensitive element of the pixel; and an electronic circuit interconnected between said 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 said input channel for accumulating a charge corresponding to received intensity generated by said pixel during a single frame period, and is connected to said output readout utility for transmitting image data thereto. The signal analyzer unit is controllably linked to said input channel for receiving and analyzing at least a part of said image signal, and is connected to said output readout utility, and is configured and operable for analyzing said at least a part of said image signal by determining an amount of accumulated charge corresponding to said received intensity, and upon detecting that said amount of the accumulated charge satisfies a predetermined condition generating data indicative of a detected event and transmitting said data to said output readout utility. |
