    • A solid state image sensor comprising a plurality of photosensors (8A) including a plurality of avalanche photodiodes (12A) arranged at least in the form of a one-dimensional array and delivering pulse signals each representing the number of photons incident to each of the photosensors; counters (10A) connected to the respective photosensors (8A) to count the pulse signals and hold the count value as a video output; a reset circuit (5) for resetting the counters (10A) to the initial states at a predetermined frequency; and a scanning circuit (14) for sequentially reading out the count value in the counters (10A). The counter (10A) counts the number of photons subjected to photoelectric conversion by the photodiode (12A) so that the video signal is directly derived in the form of a digital signal and thus the video signal with a high S/N ratio is obtained.

    • A two-dimensional solid-state image sensor device comprising a plurality of picture cells two-dimensionally arranged in column and row directions. Each cell has a static induction transistor having drain and source regions disposed on opposite sides of a high resistance semiconductor channel region, and a gate region adjacent to the channel region to control a current flowing between the drain and source regions, and a transparent electrode disposed via a capacitance on at least a portion of the gate region, in a manner that light is incident through the transparent electrode to the gate region in which the charge produced by the light excitation is stored to control the current. Selection lines connected to the gate regions in each column in common via the capacitances are sequentially selected. A readout pulse voltage is applied to the selected selection line during one horizontal scanning period and a refresh pulse voltage larger than the readout pulse voltage is applied to the selected selection line during one horizontal blanking period subsequent to the horizontal scanning period. Each picture cell is selected in the column and row directions so that a signal is read out therefrom.
