Abstract
A solid-state imaging apparatus has a plurality of pixels arranged linearly along columns of N, a plurality of clamping capacitors each arranged corresponding to each column of the pixels, for accumulating the charge amplified by an amplifying unit in the pixel, and a common node arranged corresponding to each set including the clamping capacitors of L (L is equal to or larger than 2, and a divisor of N), and connectable to each set including the clamping capacitors of L. A plurality of pixel selection switches are connected between the clamping capacitor and the common node, and a clamping unit clamps the common nodes to a reference potential. In addition, a sampling and holding circuit connects to the common nodes through the clamping unit, and samples and holds a charge corresponding to a charge of the common node.
