Abstract
A solid-state image sensing device includes: a pixel unit that has plural pixels and outputs analog pixel signals; a ramp signal generator unit that generates a ramp signal having a predetermined initial voltage and a fixed gradient; and an analog-digital converter unit that compares the analog pixel signals output by the pixel unit to the ramp signal generated by the ramp signal generator unit and digitally converts the analog pixel signals based on a comparison time, wherein the analog-digital converter unit can perform operation in a digital addition mode of adding the analog pixel signals output from the plural pixels of the pixel unit among plural pixels and outputting the signals as digital pixel signals, and the ramp signal generator unit can set the initial voltage of the ramp signal to an arbitrary value after resetting a potential of the ramp signal in the digital addition mode.
