Claim 0:
1. A solid-state sensing image device comprising:
a pixel array including a plurality of pixels arranged in a matrix form and a plurality of pixel signal lines connected to the plurality of pixels and receiving pixel signals supplied from the plurality of pixels;
a column-parallel A/D converting circuit connected to the plurality of pixel signal lines; and
a reference-voltage generating circuit generating a ramp-wave reference voltage that linearly changes in accordance with time passage,
wherein the column-parallel A/D converting circuit includes a first A/D converter,
wherein the first A/D converter includes:
a first input terminal connected to the pixel signal line;
a second input terminal receiving the reference voltage; and
an offset generating circuit connected to the first input terminal and generating an offset voltage for the first input terminal,

wherein the offset generating circuit includes two switch elements and a capacitance element, and
wherein the offset voltage is generated by the two switch elements and the capacitance element.
