description A one-dimensional time-delay integration type solid-state imager includes a plurality of photo-electricity conversion parts which stores signal charges caused by incident light arranged on a semiconductor substrate, a vertical CCD provided corresponding to a train of the photoelectricity conversion parts for reading out signal charges stored at the photo-electricity conversion parts, and gate means for reading out signal charges stored at the photoelectricity conversion parts to the vertical CCD. The signal charges corresponding to the same observed image among signal charges successively moving on the plurality of photo-electricity conversion parts are added onto the same vertical CCD thereby to enhance the signal-to-noise ratio, and a background signal charge removing region for removing background signal charges, is provided at the vertical charge transfer part at a later stage of the vertical CCD, and background signals are removed in the period of the vertical charge transfer of signal charges.
