PROBLEM TO BE SOLVED: To attain a wide dynamic range and a high low-illumination sensitivity of a solid state imaging apparatus having a photodiode and a first transistor provided in series between a ground and a drain for every pixel, to output a signal corresponding to a current or charge generated by the photodiode according to a light input from a detection node between the photodiode and the first transistor. SOLUTION: The imaging apparatus controls to alternately repeat a logarithmic operating period for obtaining a logarithmic-converted photoelectric conversion signal with the gate potentialϕ<SB>R</SB>of a first transistor set to a first level and a linear operating period for obtaining a linear photoelectric conversion signal with the gate potentialϕ<SB>R</SB>of the first transistor set to a second level.
