Abstract:
1. A photosensor system comprising: a photosensor array including a plurality of photosensors arranged two-dimensionally; initializing means for applying a reset pulse signal to each of the photosensors of the photosensor array, thereby initializing the photosensors; signal readout means for applying a pre-charge pulse signal to each of the photosensors of the photosensor array, applying a readout pulse signal to each of the photosensors, and receiving a voltage output from each of the photosensors; and effective voltage adjusting means for applying, to each of the photosensors, correction signals for correcting, to optimal values, effective voltages of the signals applied to each of the photosensors by the initializing means and the signal readout means, wherein the correction signals applied by the effective voltage adjusting means set, at 0 V, average effective voltages of the signals applied to the photosensors by the initializing means and the signal readout means.
