Abstract: An apparatus for controlling a pixel output level includes a column signal line connected to an output node of at least one pixel sensor. The apparatus includes a load circuit is connected between the column signal line and a ground terminal. The apparatus also includes a level adjusting circuit configured to adjust a voltage level of a pixel signal output from the at least one pixel sensor to the column signal line based on a correction target value.
