ABSTRACT:
A solid-state image sensor device comprises a photoelectric converter for converting incident light to electric charge, a logarithmic converter for logarithmically converting a photoelectric current output from the photoelectric converter, the logarithmic converter consisting of a first MOS transistor including a source connected to the photoelectric converter and a drain connected to a power source, and a read-out section for reading out a signal obtained by the first MOS transistor converting the photoelectric current output from the photoelectric converter, the read-out section including a second MOS transistor including a gate connected to the photodiode and a source of the first MOS transistor and a drain connected to a drain of the first MOS transistor. A gate potential of the first MOS transistor is fixed between a power source potential and a ground potential.
