An image sensing device includes a pixel array, a plurality of column amplification units each including a setting unit, and a plurality of reference signal supply units. A first reference signal and a second reference signal are common to a plurality of columns in the pixel array. Each of the plurality of column amplification units amplifies the difference between the first reference signal and the second reference signal to output the amplified difference, or amplifies each of the first reference signal and the second reference signal to output the amplified first reference signal and the amplified second reference signal. The setting unit of each amplification unit sets an amplification factor which is determined in accordance with a signal output from each of the plurality of column amplification units so as to reduce variations of the amplification factor between the plurality of column amplification units. |
