Abstract
A solid-state imaging device of the invention is provided with a CCD-structured branching unit which selects one signal charge sensor having characteristics suitable for the conditions of use from among a plurality of signal charge sensors each having different characteristics and forms a signal charge transmission path leading from the horizontal CCD to the selected signal charge sensor. As a result, there is no need to switch over the external circuit of the solid-state imaging device according to the conditions of use, which makes it possible to hold down the cost and reduce the size of the external size.
