Disclosed herein is a solid-state image sensing device comprising a plurality of pixels. Each of the pixels comprises (1) a photodiode for generating an electric signal according to an amount of light projected thereto, (2) a converter capable of logarithmically converting the electric signal into a converted electric signal while a first voltage is biased, and (3) a switching element for electrically connecting and disconnecting the photoelectric converting element and the converter. The switching element electrically disconnects the photodiode and the converter while outputting an electric signal for correcting a sensitivity unevenness among the plurality of pixels. The converting element is temporarily biased by a second voltage before taking the image, the second voltage being suitable for discharging an electric charge from the photodiode and being different from the first voltage.
